Safety Rules for the Operation of Snow Throwers

BEFORE STARTING:

1. Read the instruction manual and safety precautions furnished with your snow thrower before attempt
ing to assemble or start it.

2. Familiarize yourself with the controls and use of the equipment.

3. Check the fuel level before each use to avoid refilling the tank while the engine is hot. Wipe off
any gasoline spills and be sure the tank cap is snug.

4. Keep the area to be plowed free of sticks, stones, toys and other obstacles which could be picked
up and thrown by the impeller.

5. If your thrower is electrically powered, assure yourself that the unit is effectively and continously
grounded and that the power and extension cords are in good condition.

6. If your engine has a wind-up (rächet or impulse) starter, assure yourself that the engine will operate
freely before actuating the starter release.

7. Before starting the engine, be sure to disengage all clutches and check to see that all rotors, augers,
and impellers are free to rotate.

8. Assume a firm stance and keep your feet at a safe distance from the auger before pulling the starter
rope.

9. Do not loan your snow thrower to any person who is not familiar with its operation or the safety
rules concerning it, and don’t allow children or young teenagers to operate it.

DURING OPERATION:

1. Never attempt to clear debris from your snow thrower, make adjustments, or change the “throw”
direction of the discharge chute (unless a control is provided for this purpose near the handle), with
out first shutting off the engine and disconnecting the spark plug wire. The wire should be kept at
least two inches from the spark plug. If the thrower is electrically powered, unplug the power cord.

2. Keep children and pets away from the area being plowed, and never walk in front of the discharge
chute while the unit is running.

3. Do not place hands, feet, and loose clothing near any moving parts and always keep all guards
in place.

4. Never leave the thrower running unattended.

5. Be sure of your footing at all times and never operate the unit on precarious surfaces.

6. Never attempt to scrape off all the snow from gravel and crushed rock surfaces. Instead, adjust the
height to approximately an inch above the surface.

7. If it is necessary to operate the engine in a garage or other enclosed space, open doors and win
dows to provide sufficient ventilation.

8. Never attempt to operate the unit faster than the speeds specified by the manufacturer.

9. Keep all nuts and bolts tight. If undue vibration is noted, do not use until the condition has been
corrected.
