• SAFETY INSTRUCTIONS Before Operation Carefully follow the operating instructions in this manual. and maintenance An Operator’s Handbook is attached to the operator cab of the Excavator. Its brief instructions are convenient to the operator. The dealer and owner/operator review the recommended uses of the product when delivered. If the owners/ operators will be using the machine for a different application(s) they must ask the dealer for recommendations on the new use.
SAFETY INSTRUCTIONS (CONT’D) A Qualified Operator Must Do The Following: Safe Operation Is The Operator’s Responsibility Understand the Written Instructions, Rules and Regulations Safety Alert Symbol • The written instructions from Bobcat Company include the Delivery Report, Operation and Maintenance Manual, Operator’s Handbook and machine signs (stickers). • Check the rules and regulations at your location. The rules may include an employer’s work safety requirements.
• SAFETY INSTRUCTIONS (CONT’D) Fire Prevention The machines and some attachments have components that are at high temperatures under normal operating conditions. The primary source of high temperatures is the engine and exhaust system. The electrical system, if damaged or incorrectly maintained, can be a source of arcs or sparks. Use the procedure in the Operation and Maintenance Manual for cleaning the spark arrester silencer (if equipped). Figure 1 Flammable debris (leaves, straw, etc.

DAILY INSPECTION Procedure Maintenance work must be carried out at regular intervals. Failure to do so will result in excessive wear and early failures. The Service Schedule is a guide for correct maintenance of the Bobcat Excavator. It is located inside the rear door of the excavator and also in the MACHINE SIGN TRANSLATION SECTION. Check the following items before each day of operation: • Operator Canopy or Cab (ROPS/TOPS) and mounting hardware. • Seat belt and mounting hardware.

Figure OI-89 ATTACHMENTS (CONT’D) Using The X-Change System (Cont’d) Removing Bucket Or Attachment (X-Change System) The excavator is equipped with the X-Change system. The X-Change is used for fast changing of buckets and attachments. 2 NOTE: Removal and installation of the bucket is shown. The procedure is the same for other attachments. Disconnect any hydraulic lines that are operated by hydraulic power before removing any attachments (breaker, auger, etc.).
ATTACHMENTS (CONT’D) To Connect: Quick Connectors Remove any dirt or debris from the surface of both the male and female connectors, and from the outside diameter of the male connector. Check the connectors for corroding, cracking, damage, or excessive wear. If any of these conditions exist, the connector(s) (Item 1) [Figure OI-91] must be replaced. WARNING AVOID BURNS Hydraulic fluid, tubes, fittings and quick connectors can become hot when running machine and attachments.
ATTACHMENTS (CONT’D) Relieving Hydraulic Pressure Auxiliary Hydraulics Stop the engine and turn the key to ON (Standard) or press ENTER CODE Button (Keyless). Figure OI-93 Press AUX HYD Button (Item 1) [Figure OI-93] and then move the switch (Item 1) [Figure OI-94] to the right and left several times. 1 Return To Tank Valve (If Equipped) Figure OI-95 P16616 1 Press the Auxiliary Hydraulics button on the right console (Item 1) [Figure OI-93].
Lowering The Work Equipment With Engine Stopped Make sure the load is evenly weighted and centred on the lifting chain, and is secured to prevent the load from shifting [Figure OI-96]. If the engine stops, the work equipment (boom/bucket, attachments) can be lowered to the ground using hydraulic pressure which is stored in the accumulator. Lift and position the load. When the load is in position and tension is removed from the lift chain (secondary lift system), remove the secondary lift system.
Figure OI-100 OPERATING PROCEDURE (CONT’D) Excavating Lower the blade to provide stability. Figure OI-98 MS-1854 Raise the boom, retract the arm and curl the bucket [Figure OI-100]. Rotate the upperstructure. MS1855 NOTE: Do not allow the bucket teeth to make contact with the ground when slewing the upperstructure. Extend the arm, lower the boom, and open the bucket [Figure OI-98]. Figure OI-99 WARNING Keep all onlookers 6 m away from equipment when operating.
OPERATING PROCEDURE (CONT’D) Figure OI-102 Excavating (Cont’d) WRONG Figure OI-101 MS1857 Do not dig under the excavator [Figure OI-102]. B-19943 Do not use the bucket as a breaker or pile driver. It is better to excavate hard or rocky ground after breaking it with other equipment. This will reduce damage to the excavator. Extend the arm and uncurl the bucket to dump the material into a pile or truck [Figure OI-101]. Do not move the excavator while the bucket is in the ground.
OPERATING PROCEDURE (CONT’D) Figure OI-105 Boom Swing Figure OI-103 B-19996 Slew the upperstructure, swing the boom to the right [Figure OI-103], centre [Figure OI-104] and left [Figure OI-105] to dig a square hole the width of the machine without repositioning the excavator. B-19994 Figure OI-104 Figure OI-106 B-19995 B-19937 The boom swing allows the operator to offset the boom and dig close to buildings and other structures [Figure OI-106].
Figure OI-109 OPERATING PROCEDURE (CONT’D) Backfilling Figure OI-107 B-19939 The bucket can also be used to pull the excavator. Raise the blade, extend the arm and lower the boom. Operate the boom and arm in a digging manner [Figure OI-109]. B-19940 Use the blade to backfill the trench or hole after excavating [Figure OI-107]. Driving The Excavator When operating on uneven ground, operate as slowly as possible and avoid sudden changes in direction.
OPERATING PROCEDURE (CONT’D) WARNING Operating On Slopes WARNING • • • • • AVOID INJURY OR DEATH Do not drive across or up slopes that are over 15 degrees. Do not drive down or back up slopes that exceed 25 degrees. Look in the direction of driving. • AVOID INJURY OR DEATH Avoid steep areas or banks that could break away. Keep boom centred and attachments as low as possible when driving on slopes or in rough conditions. Look in the direction of driving. Always fasten seat belt.
Figure OI-114 OPERATING PROCEDURE (CONT’D) Operating On Slopes (Cont’d) Forward 1 Figure OI-113 Neutral Recommended Position For Working On A Slope Reverse P-49125 To brake the machine when going down a slope, move the steering columns (Item 1) [Figure OI-114] to the NEUTRAL position. This will engage the hydrostatic braking. B-19935 When operating on a slope, level the work area before beginning [Figure OI-113]. When the engine stops on a slope, move the steering columns to the neutral position.
OPERATING PROCEDURE (CONT’D) Operating In Water Mud and water should be removed from the machine before parking. In freezing temperatures, park the machine on planks or concrete to prevent the track or undercarriage from freezing to the ground and preventing machine movement.
