OPERATION Attachment Clutch – Right Hand Lever WARNING: AVOID INJURY. Read and understand the entire Safety section before proceeding. 2 WARNING: To avoid injury to hands and feet, always disengage clutches, shut off engine, and wait for all movement to stop before unclogging or working on snow thrower. Keep hands and feet away from auger and impeller. CONTROLS AND FEATURES See CONTROLS and FEATURES on pages 12 and 13 for all Controls and Features locations.
Choke Control Knob 2 1 692 ',3/) OS7275 1.Choke Closed position: chokes off air to engine for easier start. 2.Choke Open position: allows for normal operation. IMPORTANT: Gradually open choke after engine starts. Snow Clean-Out Tool Throttle 3 2 1 Figure 11 The throttle controls the engine speed. To increase or decrease the engine speed, adjust to: 1. Fast 2. Part-Throttle 3.
IMPORTANT: Before starting or operating ensure that the bypass rod is pushed fully into the machine. Failure to close the bypass rod may result in damage to the transmission. Heated Handles Turn the heated handles switch to the ON (1) position to activate. Turn the switch to the OFF (2) position to deactivate. 1 2 OS1950 Scraper Blade The scraper blade allows better contact with the surface being cleared. It also prevents damage to the housing from normal usage.
Stored Position Normal Transport Operating Position Deep Cutting OS7111 Figure 15 FILLING FUEL TANK Figure 14 WARNING: AVOID INJURY. Read and understand the entire Safety section before proceeding. OS7110 Track Angle (926056) GASOLINE (Figure 15) The track angle can be adjusted to position the auger housing for level clearing, deep cutting or transport. Squeeze the handlebar trigger and press down on the handlebars to move the auger housing into an up position.
NOTE: All gasoline is not the same. If the engine experiences starting or performance problems after using a new gasoline, switch to a different fuel provider or fuel brand. IMPORTANT: Excessively oxygenated or reformulated fuels (fuels blended with alcohols or ethers) can damage the fuel system or cause performance problems. If any undesirable operating problems occur, use a gasoline with a lower percentage of alcohol or ether.
5. Check Engine Fuel & Crankcase Oil WARNING: AVOID INJURY. Read and understand the entire Safety section before proceeding. Check and add fuel if required. Check that the engine crankcase oil is full using dipstick. Refer to Engine Manual for detailed instructions. TO STOP IN AN EMERGENCY Immediately release both control levers to stop unit in an emergency. Stop engine, remove key and wait for all rotating parts to stop before leaving operator’s position.
SNOW REMOVAL IMPORTANT: Allow unit and engine to adjust to the outdoor temperature before clearing snow. NOTE: Attachment clutch should be engaged before traction drive clutch when throwing snow. 1. Select Speed Control position and direction. 2. Engage Attachment Clutch – Right Hand Lever. 3. Engage Traction Drive Clutch – Left Hand Lever. IMPORTANT: DO NOT overload unit capacity by attempting to clear snow at too fast a rate. Use slow speed to clear deep or hard packed snow.
MAINTENANCE Ariens Dealers will provide any service or adjustments which may be required to keep your unit operating at peak efficiency. Should engine service be required, contact an Ariens dealer or an authorized engine manufacturer's service center. MAINTENANCE SCHEDULE The chart below shows the recommended maintenance schedule that should be performed on a regular basis. More frequent service may be required. MAINTENANCE SCHEDULE WARNING: AVOID INJURY.
CHECK CLUTCH OPERATION Auger / impeller must stop within 5 seconds when attachment clutch lever is released. Wheels must stop quickly when traction drive clutch lever is released. If clutches do not engage or disengage properly, adjust or repair before operation. See Attachment Clutch/Brake Adjustment on page 26 and Traction Drive Clutch Adjustment on page 28.
GENERAL LUBRICATION (Figure 18) IMPORTANT: Wipe each fitting clean before and after lubrication. IMPORTANT: DO NOT allow grease or oil to get on belts. NOTE: Apply Ariens Hi-Temp Grease or equivalent to the lubrication fittings. See SERVICE PARTS on page 31. Sno-Thro should be lubricated (Figure 18) at beginning of season or every 25 operating hours. Auger Shaft To grease auger shaft, remove shear bolt nuts and shear bolts per instructions in Shear Bolts on page 24.
SERVICE AND ADJUSTMENTS SHEAR BOLTS WARNING: AVOID INJURY. Read and understand the entire Safety section before proceeding. (Figure 20) SCRAPER BLADE IMPORTANT: Damage to auger/impeller housing will result if blade wears down too far. Scraper blade is adjustable to compensate for wear. To adjust scraper blade: 1. Tip unit back onto handlebar, support housing and loosen nuts retaining blade. 2. Reposition scraper blade and tighten lock nuts. 3. Adjust skid shoes.
HANDLEBAR HEIGHT 7. Re-install bottom cover. (Figure 21) REMOTE DEFLECTOR CONTROL CAUTION: AVOID INJURY. Adjust the attachment clutch, speed selector and traction clutch after changing the handlebar height. See Attachment Clutch/Brake Adjustment on page 26, Traction Drive Clutch Adjustment on page 28 and Speed Selector Adjustment on page 26. To raise or lower the handlebar: 1. Place unit in service position (see Service Position on page 21). 2. Remove bottom cover. 3.
DISCHARGE CHUTE CONTROL (Figure 23) If chute does not stay in position while throwing snow or if chute does not rotate freely, adjust the cable under the gear cover so the chute lock fingers engage or disengage the locking gear. If chute does not stay in position: Loosen the cable by loosening the rear adjustment nut, and then tightening the forward adjustment nut against the bracket until the lock arm engages the gear teeth. 1 3 4 5 2 Forward Adjustment Nut 1. 2. 3. 4. 5.
Check Attachment Idler Arm Roller Clearance 1 2 3 OS7185 OS7191 1. Attachment Clutch Cable 2. Adjustment Barrel 3. Jam Nut Figure 25 5. With the attachment clutch disengaged, check that the attachment idler arm lightly touches the frame (Figure 26). 6. Tighten jam nut on the adjustment barrel. (Figure 27) NOTE: It will be difficult to check the measurement inside the frame. Use a 1/2" (12.7 mm) minimum spacer as a gauge to check the clearance between the roller and the frame. 1.
Check Attachment Brake (Figure 28) 1. With the clutch lever disengaged, brake pad must contact attachment belts. With clutch lever engaged, brake pad must be more than 1/16" (1.6 mm) from belts. If there is more than 1/16" (1.6 mm) gap, go to Check Belt Finger Clearance on page 28. If there is less than 1/16" (1.6 mm) gap, go to step 2. Check belt finger clearance here. With the attachment clutch engaged, there should be less than 1/8" (3 mm) clearance between the belts and the belt finger.
7. Remove attachment drive belts from engine sheave (it may be necessary to turn engine sheave using recoil starter handle). IMPORTANT: To avoid bending bottom cover when tipping unit apart, support handlebars firmly or tip unit up on housing and remove bottom cover by removing six cap screws before separating unit. 8. Support Sno-Thro frame and housing. CAUTION: Always support SnoThro frame and blower housing when loosening the cap screws holding them together.
TRACK TENSION ADJUSTMENT (926056) (Figure 32 and 33) Check the track tension by applying pressure on the track midway between the upper and rear track rollers. Deflection should be approximately 3/8" (9.6 mm) (Figure 32). If deflection is excessive, tighten the track tension. 3/8" (9.6 mm) HEIGHT ADJUSTER CABLE ADJUSTMENT (926056) (Figure 34): 1. Make sure that height adjustment lock finger is fully engaged. 2. Loosen jam nut on cable adjustment barrel. 3.
Keep all nuts, bolts and screws properly tightened and know unit is in safe working condition. Store unit in a cool, dry protected area. SERVICE PARTS Order the following parts through your Dealer: Part No. LONG TERM Clean unit thoroughly with mild soap and low pressure water and lubricate (see MAINTENANCE on page 21). Touch up all scratched painted surfaces. Remove weight from wheels by putting blocks under frame or axle.
