Run-in Attachment Belt 1. Start unit in a well-ventilated area according to Starting and Shut-Off in Operation. 2. Engage attachment clutch lever and run attachment for about 15 minutes. 3. Stop unit, wait for all moving parts to stop, and remove spark plug wire. 4. Adjust belt finger, if necessasry. See Attachment Drive Belt Replacement on page 22. 5.

OPERATION IMPORTANT: If the belt squeals when the attachment clutch lever is engaged, the attachment drive may be frozen. Immediately release the attachment clutch lever and move the unit into a heated area to thaw. WARNING: AVOID INJURY. Read and understand the entire Safety section before proceeding. Ignition Switch 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.
Throttle 1 2 3 STOP The throttle controls the engine speed. To increase or decrease the engine speed, adjust to: 1. Fast (normal or warm starts) 2. Part-Throttle 3. Slow (cold weather starts) 4. Stop (engine is off) 4 Push deflector remote forward to throw snow lower. Pull deflector remote back to throw snow higher. Discharge Chute Discharge chute rotates 215°. ALWAYS position discharge chute in safe direction and angle, away from operator and bystanders, before starting engine.
FILLING FUEL TANK Scraper Blade The scraper blade allows the back of the housing to keep better contact with the surface being cleared. It also prevents damage to the housing from normal wear. IMPORTANT: DO NOT allow Scraper Blade to wear too far or Auger/Impeller housing will become damaged. Runners The runners control the distance between the scraper blade and the ground. Adjust runners equally to keep blade level with the ground. Refer to Pre-Start for recommended settings.
3. Check Dual Handle Interlock Without the engine running, press down (engage) both clutch levers. Release attachment clutch lever. Attachment clutch should remain engaged until traction clutch lever is released, then both clutches must disengage. If clutches do not engage or disengage properly, adjust or repair before operation (see Service and Adjustments). 4. Adjust Axle Lock Use the axle lock pin to lock or unlock the right wheel.
IMPORTANT: DO NOT operate starter more than 15 seconds per minute, as overheating and damage can occur. (If engine does not start, refer to Troubleshooting.) 10. Adjust choke as needed. 11. Disconnect power cord from outlet, then starter. 12. Set throttle to Part Throttle or Slow position for travel or adaptation to outside temperature. Once achieved, set throttle to Fast position for normal operation. Shut Off 1. Release Traction Drive Clutch Lever and allow unit to come to a complete stop. 2.
CHECK ENGINE OIL MAINTENANCE SCHEDULE Service Performed Each Every Every Yearly Use 5 hrs. 25 hrs. Check Dual Handle Interlock • Check Fasteners • Check Clutches • Clean Engine • The engine crankcase oil should be checked every 5 hours of operation. Oil level MUST be maintained in safe operating range on dipstick at all times or engine damage will result (See Engine Manual). Park unit on a level surface. Refer to Engine Manual for detailed instructions.
GENERAL LUBRICATION Auger Shaft IMPORTANT: Wipe each fitting clean before and after lubrication. IMPORTANT: DO NOT allow grease or oil to get on friction disc, friction plate or belts.
