DESCRIPTION ELGIN PELICAN® Series P DESCRIPTION Sweeper efficiently cleans large, paved areas, such as streets and parking lots. It can be equipped with a broom on each side to increase total sweeping path. Side brooms also help to bring debris out of the gutter and onto the conveyor.
PRINCIPLES OF OPERATION WHY SWEEP? DESCRIPTION Street sweeping is an essential part of sanitation. In health, ecology and aesthetics, the community benefits from clean streets. Clean streets reduce dust and dust-borne contaminants, bacteria from decomposition of organic matter, pollutants entering stormwater systems and accidents due to debris in the roadway. Community pride is enhanced by a clean environment. People are less likely to litter in a clean area.
The amount of water is adjustable through use of a knob inside the cab. A 180-gallon (681 L) water tank is standard on the Pelican P, with an optional 40-gallon (151 L) tank available. CONVEYOR The heavy-duty, multi-ply reinforced No Jam™ debris conveyor (Figure D-1) transports debris BROOMS The pattern that the brooms produce when the sweeper is stationary is a tool to evaluate the most efficient positioning of the brooms. The brooms can be adjusted to produce the best pattern and result.
deposited on it by the main broom to the hopper. Speed is in-cab controlled for variable forward and reverse. full-width windshield and rear windows allow the operator to see everything that is happening while sweeping. Pavement contact is maintained by rubber dirt shoes on the sides and rubber deflectors under the chassis. DESCRIPTION HOPPER Debris is collected in the 3.5 yd3 (2.7 m3) volumetric capacity hopper. The forward dumping hopper allows dumping to occur using only one lane of traffic.
CONTROLS DRIVE WHEELS All sweeping functions, including brooms and hopper, are powered through in-cab controls (Figure D3), located comfortably within reach. The Pelican P features a unique wheel motor design (Figure D-4) to provide power to handle all road conditions include steep grades. Sensors adjust the power required according to the load. DESCRIPTION For a complete description of all controls, see the Operations Section.
GUIDE WHEEL The rear, dual-tire, guide wheel (Figure D-5) allows superior maneuverability to get around parked cars and tight corners. DESCRIPTION An optional sprung guide wheel increases operator comfort and decreases stress on the sweeper. The 4spring suspension absorbs shock and is especially important in areas with a number of potholes.

DO NOT modify or tamper with the exhaust system. NOTICE Never operate the starter for more than 10 seconds. Longer operation will lead to an over discharge of the batteries, as well as starter seizure. Wait at least 30 seconds between attempts to start the engine. 3.
Check the Engine Oil Pressure and Fuel gauges (16 and 11, Figure O-1) to be sure there are no problems. COLD WEATHER STARTING ! WARNING NOTICE Never operate the starter for more than 10 seconds. Longer operation will lead to an over discharge of the batteries, as well as starter seizure. Wait at least 30 seconds between attempts to start the engine. 3.
6. 7. Allow the engine to warm up at normal idling speed of 1000 rpm. To raise RPM, depress the button on the Engine Throttle Control knob (53, Figure O-2) to release the lock, and pull the knob up. For fine tuning, rotate the knob clockwise or counterclockwise. Check the Engine Oil Pressure and Fuel gauges (16 and 11, Figure O-1) to be sure there are no problems. ating and monitor them for people outside of your direct field of vision.
2. At the front of the sweeper, properly adjust the round, convex mirrors (Figures O-3 and O-4) to give an operator in either operating position a clear view of any and all obstacles and/or pedestrians in front of the sweeper. After starting and warming up the engine, turn on the needed lights by using the Hazard (33, Figure O-1), Head Lights (35), and optional Beacon (34) switches. 3. Release the parking brake. 4.
suspension, use the CONV LOWER / MB/CONV UP switch (47) to raise the main broom and conveyor. 7. Set the Engine Throttle Control (53, Figure O-2) for transport RPM. 8. Turn on the lights, using the Hazard switch (33), Head Lights switch (35), and optional Beacon switch (34) as needed. 9. Ensure that the front of the machine is clear before moving it forward. During operation of the sweeper, monitor the front round mirrors for people outside of your direct field of view.
! CAUTION If the operator has not operated a vehicle with rear-wheel steering, the operator must practice driving the Pelican in a non-congested, open area until totally familiar with the steering. ! before and while moving forward. Properly adjust front round convex mirrors before operating and monitor them for people outside of your direct field of vision. ! 1. Before operating the sweeper, adjust the front round mirrors as instructed at Transport. 2.
4. With the conveyor completely lowered, if the main broom is not at proper height, use the same switch (50) to adjust broom height. This adjustment will not affect the height of the conveyor. 5. Start conveyor rotation by using the Conveyor Rotate switch (49). OPERATION 6. Lower the side broom(s) by using the Broom Height switch(es) (26 and/or 46). 7. As necessary, start rotation of brooms by using the Broom Rotate switches (22, 27, 45). 8.
12. Ensure that the front of the machine is clear before moving it forward. During operation of the sweeper, monitor the front round mirrors for people outside of your direct field of view. When sweeping, to keep the sweeper evenly aligned with the curb, choose a focal point on the front of the sweeper, such as the edge of the mirror or a place on the hopper, and line it up with the edge of the curb ahead of the sweeper. This eliminates any tendency to oversteer the sweeper.
While sweeping light material like leaves, if the sweeper starts pushing a pile of the material, sweeping may be improved by raising the conveyor slightly. To make this change, tap the MB / Conv Height switch (50, Figure O-1). SWEEPING PATTERNS Side Broom Patterns (Must overlap Main Broom Pattern) Broom sweeping patterns are a guideline of sweeping performance. Patterns should be checked daily. A pattern may be wrong because of incorrect broom downpressure, incorrect broom angle, or excessive broom wear.
If a broom’s bristles have worn to less than half of their original length, the broom will produce a small pattern and poor sweeping performance. 5. Using the Engine Throttle Control knob (53, Figure O-2), increase engine speed to about 2500 rpm. 6. Sweep in one spot for about 15 seconds. 7. Stop broom rotation by using the Broom Rotate switches (22, 27, and/or 45, Figure O-1). 8. Use the Broom Height switch(es) (26 and/or 46) to raise the side brooms. 9.
at the top. The patterns should overlap the path of the main broom (Figure O-8). 12. Check that the main broom pattern is of an even width along its whole length (does not taper). The pattern should be 4 to 6 inches (10 to 15 cm) wide. After sweeping, the broom bristle tips should have an even amount of dirt on all of them. If the patterns do not conform to those in Figure O8, adjust or replace the brooms, as necessary, by the procedures in the Service Procedures section.
To reverse the conveyor, take the following steps. 1. Slow the engine. 2. Press the 3-position Conveyor Rotate switch (49, Figure O-1) to Off until the conveyor stops. 3. Press the switch to Reverse just long enough to remove the jammed object. DUMPING THE HOPPER ! clearance of 3 ft (1 m). Do not raise hopper while under trees, bridges, etc. ! 1. Come to a complete stop on level surface. 2. Stop rotation of conveyor by using Conveyor Rotate switch (49, Figure O-1). 3.
sion, use CONV LOWER / MB/CONV UP switch (47) to raise main broom and conveyor. 6. Use the Hopper Dump Control (Figure O-10) to control hopper raising and rollout. To raise hopper: move control forward To lower hopper: move control back To roll out hopper: move control to left To roll back hopper: move control to right Hopper requires alternate operation of raise and rollout functions. Be careful not to roll out hopper too far until sweeper is in position to dump hopper. 7.
SHUTTING DOWN THE UNIT Park the sweeper. 2. Use the Engine Throttle Control (53, Figure O-2) to set engine speed to idle (about 1000 RPM). 3. Set the parking brake. 4. Stop rotation of the conveyor by using the Conveyor Rotate switch (49, Figure O-1). 5. As necessary, stop rotation of the brooms by using the Broom Rotate switches (22, 27, 45). 6. Raise the side broom(s) by using the Broom Height switches (26 and/or 46). 7.
After washdown is complete, maintenance must be performed as directed in the Maintenance and Service Procedures sections. Filling the fuel tank at the end of the shift will force most of the air out of the tank. This action will minimize the water condensation that can happen in the air space as the tank cools.
SCHEDULED MAINTENANCE Wash down machine after every sweeping shift. See Daily Washdown procedure later in this chapter. DAILY SERVICE CHECKLIST The numbers below correspond with the locations on Figures M-1, M-2, M-3 and M-4.
MAINTENANCE PERIODIC SERVICE CHECKLIST The numbers below correspond with the locations on Figures M-1, M-2, M-3 and M-4.
After 5000 hours or 5 years (whichever occurs first), or when servicing the guide wheel as a result of impact damage, replace the guide wheel pivot pin. Examples of impact damage might be, but are not limited to: Bent rim, tire damage, axle damage, etc. Contact Elgin dealer with any questions.

Park the sweeper on a flat, level surface, away from power lines, trees, etc. ! Raise hopper only in areas with minimum overhead clearance of 16 ft (5 m) and forward clearance of 3 ft (1 m). Do not raise hopper while under trees, bridges, etc. 3.
5. MAINTENANCE Raise Roll out Roll back Lower Hopper Dump Control Figure M-6 Lower the main broom, conveyor and side broom(s) to sweeping positions. Start rotation of the main broom and conveyor. 6. Fill the water tank to overflowing, allowing the water to flush the conveyor belt for one to two minutes. Reverse the conveyor several times during this flushing. 7. With the conveyor still running forward, use high pressure water to flush the conveyor and belt backing plate. 8.
11. After engine has cooled, washdown engine compartment, including engine radiator and oil cooler. 1. Thoroughly clean the window with ammonia and water, being sure to remove all dirt that may be embedded in scratches or cracks. MAINTENANCE NOTICE Never steam clean or wash an engine while it is running. Water can cause a hot manifold to crack. 2. Rinse the window completely and allow it to dry.
MAINTENANCE 3. After window is completely dry, apply a goodquality floor wax with a poly base. This will fill in any scratches and restore the clarity of the window. To avoid cracking the bubble window, always use the latches on the inside of the cab to close the window. Do not apply force to the window itself.
MAINTENANCE Higher temperatures may make it necessary to change oil more frequently. Oil Fill Level and Volume Unit should be half full. Approximate volume of hub is 37 oz (1.1 L). To check oil level: • For a hub with oil plugs 180º apart (Figure M-8), turn the hub until the plugs are level with the disconnect cover. • For a hub with oil plugs 90º apart (Figure M-9), turn the hub until the check plug is level with the disconnect cover. To drain oil, turn hub until one plug is at the bottom.

MAIN BROOM ADJUSTMENT Standard (Chain) Suspension 2. Adjust the spring tension on one side as necessary using the chain. For example, if the left side shows more wear (or taper) than the right side, shorten the chain on the left side to raise the left side of the broom. To adjust the main broom contact area with a chain suspension (Figure SP-11), take the following steps.
4. Tighten the jam nut. DIRT SHOE ADJUSTMENT Dirt shoes ride perpendicular to the ground to act as a guide to keep debris between the main broom and the conveyor. SERVICE PROCEDURES The main broom rotates between the two dirt shoes. Wings at the rear of each dirt shoe assure that the bristles are turned in and ride flush within the dirt shoe housings. Hydraulic Main Broom Suspension Figure SP-12 2. Loosen the jam nut. 3. Turn the adjusting nut up or down as needed.
raised transport position the dirt shoes should be parallel to, but not touching the ground. To raise the rear of the dirt shoes, lift the plate toward the lifting rod. To lower the rear of the dirt shoes, move the plate away from the lifting rod. Dirt Shoe Figure SP-13 3. Drive the sweeper forward to allow brooms to attain proper sweeping position. DIRT DEFLECTORS Dirt deflectors are located in various places in the Pelican. They aid in keeping debris moving toward the hopper. 4.
On Pelicans equipped with dual side brooms there are two dirt deflectors (Figure SP-14) mounted in the center of the unit. These dual dirt deflectors form a “V” under the hopper area. beyond the reach of the main broom. This runner may be adjusted by loosening the nuts in the metal plate and raising or lowering the runner as needed. All dirt deflectors should be inspected regularly and changed if damaged or worn.
! WARNING 1. Install a 1/2 x 2 1/2-inch bolt in each of the two holes located above the spring-loaded door latches on the sides of the hopper (Figure SP-15). The bolts will hold the hopper door closed during roll-out. 2. Raise the hopper slightly and begin to tilt ("roll") the hopper completely over, raising and tilting the hopper as needed. 3.
NOTICE Do not attempt to adjust the conveyor belt with the conveyor system in the raised position. Proper conveyor belt adjustment involves first setting tension and then adjusting alignment by the procedures under Belt Tension and Belt Alignment. NOTICE SERVICE PROCEDURES Conveyor Belt Adjustments Belt tension and alignment for both rolls are interrelated. During tension adjustment, the belt must be kept nearly centered, but tension must be correct before final adjustment of alignment.
BELT TENSION The conveyor belt has correct tension when there is clearance between the tip of any cleat and conveyor backing plate. If too loose, the belt may slip on the upper roll and the cleats may show wear from dragging over the backing plate. DO NOT overtighten belt, as this will cause premature failure. To adjust belt tension, use the following procedure. ! WARNING DO NOT work under or around a raised hopper. 1.
ADJUSTING NUT 5. If the belt "flaps" against the lower conveyor cover, increase overall belt tension by continuing adjustment steps on both sides of the upper conveyor roll. 6. If alignment does not need adjusting, tighten the jam nuts. SERVICE PROCEDURES BELT ALIGNMENT Proper belt alignment will require making small adjustments to the upper roll as outlined below. As a result, upper conveyor roll take-ups may not have equal final adjustments.
Reference to right or left side of the sweeper is relative to the operator's position in the driver's seat. ! WARNING DO NOT work under or around a raised hopper. Before beginning belt alignment, follow the procedure under Conveyor Access. Follow these guidelines for correct belt alignment: Adjust the conveyor to give correct belt tension before making final adjustments in alignment.
Other Conveyor Adjustments LOWER ROLL SCRAPER ADJUSTMENT SERVICE PROCEDURES Lower roll scraper adjustment should be checked periodically and whenever the belt is removed. The square opening just above the lower roll bearing (Figure SP-18) provides access for adjustment. To adjust the scraper, take the following steps. 1. Loosen two nuts at each end of the scraper. 2. Adjust the scraper to clear the roll by no more than 1/16 inch (1.6 mm). 3. Tighten the nuts.
CONVEYOR GROUND CLEARANCE Conveyor ground clearance (height) should be adjusted after the new belt is in place to ensure good conveyor performance. The clearance may be out of adjustment for a machine in the field due to wear and loosening of the lower roll bearings and conveyor lift cylinders. 6. Place a 1-5/8 ± 1/4 inch (41 ± 6 mm) wooden block under the cleat at the middle of the conveyor belt (Figure SP-19). (A standard 2 x 4 block can be used to estimate this dimension.
NOTICE Due to the lower roll offset, clearance at the left side will be slightly less than the clearance at the middle, and clearance at the right side will be greater. 7. If adjustment is necessary, take the following steps. a. Raise the conveyor. SERVICE PROCEDURES b. Block and support the conveyor. c. With the pistons of the conveyor lift cylinders (Figure SP-20) retracted, remove the snap ring at the bottom of each cylinder, and remove both cylinders. d.
! WARNING 2. Rotate the conveyor belt to expose the belt splice at the upper conveyor roll area (Figure SP-21). DO NOT work under or around a raised hopper. 3. Loosen the jam nuts and back them off the adjusting nuts on both sides of the conveyor (Figure SP-17). In preparation for replacement of the conveyor belt, the sweeper must be parked on a flat, level surface. 4. Turn the adjusting nuts to reduce overall belt tension on both sides of the belt.
5. Disassemble the belt splice and allow the belt to fall beneath the sweeper. b. Block and support the conveyor. 6. Remove the belt from under the sweeper. c. Squaring Conveyor Structure SERVICE PROCEDURES The conveyor structure should be checked and adjusted for squareness in the sweeper and to the sweeping surface. Use the following procedure. 1. On the conveyor structure, select a reference point (e.g., a bolt or bracket) that is common to both sides. 2.
Above the conveyor lift cylinders, there are two stop bolts (Figure SP-20) that guide the conveyor in tow through U-turns and sweeping, preventing damage to the conveyor and other components under the sweeper. There should be a 1/8-inch (3 mm) gap between these bolts and the sweeper side plates. The bolts should not ride against the side plates.
SERVICE PROCEDURES Left Hand Lower Roll Bearing Figure SP-22 Figure SP-23 Right-Hand Lower Roll Bearing Installing Conveyor Belt NOTICE NOTICE These settings may require slight readjustment, similar to adjustment of the upper roll, during belt tensioning and alignment. See CONVEYOR BELT ADJUSTMENT. SP-28 If the lower roll offset is properly adjusted before a new belt is installed, belt adjustment is easier.
To install a conveyor belt, use the following procedure. 1. Lower one end of the conveyer belt (cleats out) past the upper roll and down through the underside of the conveyor to the lower roll. 3. Position the entire belt as close to the center of each roller as possible. The belt edges should run parallel to the conveyor belt guide plates. 4. From a position under the machine at the lower roll, gather both ends of the belt, and install the belt splice as if you were closing a zipper (Figure SP-24).
A torn or damaged belt may be repaired in the field by cutting out the damaged part with a squared cut across the whole width of the belt and inserting a new section also squared off to match the length of the part removed (Figure SP-25). This requires two splices, one at each end of the new belt section added. Should damage occur near the original splice, the new section may be added at the end and only one splice need be added.

MAIN BROOM REPLACEMENT To prepare for the removal of the main broom on a Pelican with standard (chain) broom suspension (Figure SP-26), raise the main broom and release the suspension chains on both sides of the machine. To prepare for removal of the main broom on a Pelican with hydraulic broom suspension (Figure SP-27), lower the broom to just touch the ground. This will properly balance and suspend the main broom, making disassembly of the lefthand lower broom arm easier.
1. Turn the steering wheel all the way to the left. This will allow room to handle the main broom. ! WARNING Contact with rotating main broom can cause personal injury or property damage. Turn broom(s) and engine off before inspecting or servicing broom. 2. Shut down the engine. 3. Remove the three main broom drive hub mounting bolts from the broom core on the right side of the machine. 4. Remove the main broom lower arm mounting bolts from the left-hand upper main broom arm. 5.
10. Install the three main broom drive hub mounting bolts on the broom core on the right side of the machine. CAB AIR FILTER SERVICE PROCEDURES Clean air for the heater, air conditioner and cab pressurizer is drawn through a filter. This filter should be checked and replaced on a regular basis. The exact frequency will depend on operating conditions. To change a rear guide wheel, use a small bottle jack between the two guide wheel tires to lift the sweeper.
light. Never check battery charge by placing a metal object across the posts. Use a voltmeter or hydrometer. Always remove the grounded (—) battery cable first and connect it last. 2. Drain the fuel water separator. 3. Remove and clean the battery . Store in a cool, dry place and keep fully charged. This action will keep the battery in good condition. a. Open the water tank drain. 5. Coat all exposed metal surfaces with grease or corrosion inhibitor.
take the following steps to minimize corrosion and deterioration. 1. Change engine oil and replace the oil filter. Used oil will not give adequate protection. 2. Drain and flush the cooling system only if the engine will be stored for a year or more. SERVICE PROCEDURES 3. Loosen all belts to relieve tension. Remove the belts, if desired. 4. Seal all openings on the engine with plastic bags and tape. CAUTION Battery gas can explode. Keep sparks and flames away from batteries.
c. At the water pump, take the following steps. 5. Install a fully-charged battery, and connect the cables. 6. Follow all instructions in the Startup Checklist at the beginning of the Operation section. SERVICE PROCEDURES 1) Remove the plug at the top of the pump. 2) Fill the pump t o overflowing with water. 3) Install the plug.
