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. SAFETY ALERTS Look for these symbols to point out important safety precautions.
1. WARNING! 3. DANGER! Read Owner/Operator Manual. OL1801 OS2080 Keep people away from unit while operating. Keep children out of work area and under watchful care of a responsible adult. OL4370 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.
