SAFETY PRACTICES AND LAWS 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. Hand contact with the rotating impeller is the most common cause of injury associated with snow throwers. Never use your hand to clean out the discharge chute. Keep hands and feet away from auger and impeller. Practice usual and customary safe working precautions, for the benefit of yourself and others.
1. WARNING! 3. DANGER! Read Owner/Operator Manual. OL1801 OS2080 OL4370 Keep people away from unit while operating. Keep children out of work area and under watchful care of a responsible adult. Never direct discharge towards persons or property that may be injured or damaged by thrown objects. OL0910 Stop engine, remove key, read manual before making any repairs or adjustments. OL4010 Wear appropriate hearing protection. OL4690 ONLY use clean-out tool to clear blockages. NEVER use your hands. 2.
DO NOT operate near drop-offs, ditches, or embankments. Unit can suddenly turn over if a wheel is over the edge of a cliff or ditch, or if an edge caves in. Falling snow, fog, etc. can reduce vision and cause an accident. Operate unit only when there is good visibility and light. NEVER operate unit after or during the use of medication, drugs or alcohol. Safe operation requires your complete and unimpaired attention at all times.
Check clutch and brake operation frequently. Adjust and service as required. All motion of drive wheels and auger/impeller must stop quickly when control levers are released. DO NOT operate on steep slopes. DO NOT clear snow across the face of slopes. Keep all movement on slopes slow and gradual. DO NOT make sudden changes in speed or direction. Use a slow speed to avoid stops or shifts on slopes. Avoid starting or stopping on a slope. DO NOT park unit on a slope unless absolutely necessary.

GASOLINE 2. Check Function of Clutches IMPORTANT: ALWAYS use gasoline that meets the following guidelines: • Clean, fresh gasoline. • A minimum of 87 octane/87 AKI (91 RON). High altitude use may require a different octane. Consult your engine manual. • Gasoline with up to 10% ethanol (gasohol) or up to 15% MTBE (methyl tertiary butyl ether) is acceptable. • Use of any gasoline other than those approved above may void the engine warranty.
STARTING AND SHUT OFF Electric Start (120V) WARNING: FAILURE TO FOLLOW INSTRUCTIONS could result in personal injury and/or damage to unit. DO NOT attempt to start your unit at this time. Read entire Owner/Operator Manual and the Engine Manual first. IMPORTANT: Allow unit and engine to adjust to the outdoor temperature before clearing snow. Before shut-off, run the attachment a few minutes to prevent impeller freeze-up.
SNOW REMOVAL TRAVELING IMPORTANT: Allow unit and engine to adjust to the outdoor temperature before clearing snow. NOTE: Attachment clutch should be engaged before wheel 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 SCHEDULE CHECK CLUTCH OPERATION The chart below shows the recommended maintenance schedule that should be performed on a regular basis. More frequent service may be required. Auger / impeller must stop within 5 seconds when attachment clutch/impeller brake 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.
CHECK AUGER GEARCASE GENERAL LUBRICATION IMPORTANT: Proper oil level must be maintained. Gear cases are filled to the correct level at the factory. Unless there is evidence of leakage, no additional lubricant should be required. Check oil level each season or every 25 hours of operation. To ensure adequate lubricant level: 1. Remove filler plug (Figure 25). Lubricant must be at least up to bottom of lubricant filler hole with unit resting on a levelsurface. 2. Add lubricant if required.
SERVICE AND ADJUSTMENTS SHEAR BOLTS WARNING: AVOID INJURY. Read and understand the entire Safety section before proceeding. 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. Adjust skid shoes to fully raised position (housing closest to ground). 3.
6. Repeat steps 2 – 4 while watching cable to remove slack. 7. Check function of remote wheel lock.
