4. Keep all shields and safety devices in place. If a

shield, safety device or decal is illegible, damaged or lost, repair or replace it before beginning operation. Also, tighten any loose nuts, bolts or screws.

5. Wear adequate winter clothing and rubber boots

that will ensure proper footing on slippery surfaces. Do not wear loose fitting clothing that could possibly get caught in moving parts.

6. Always wear safety glasses or eye shields during

operation or while performing an adjustment or repair to protect eyes from foreign objects that may be thrown from the machine.

7. Adjust both skids so auger/impeller housing

clears gravel or crushed rock surfaces.

8. Before starting the engine, ensure auger/impeller

drive control and traction (wheel drive) control are in disengaged position.

9. Always use a grounded three wire plug and cord

to start snowthrower equipped with an electric starter. Extension cord must be connected to a properly grounded outlet.

16. Be attentive when using the snowthrower, and

stay alert for holes in the terrain and other hidden hazards. Be careful when clearing snow from a gravel drive because stones could be picked up and thrown if skids are not adjusted so auger/impeller housing clears all rocks.

17. Do not make any adjustments while the engine is

running, with the exception of carburetor adjustments.

18. Never direct discharge of snow or operate

snowthrower near bystanders, glass enclosures, automobiles and trucks, window wells or a drop–off without proper adjustment of the snow chute and deflector angle.

19. Clear snow from slopes by going up and down,

never across the face. Use caution when changing directions. Use lower gear when operating on slopes. Never clear snow from steep slopes.

snow at too fast a rate.

21. Do not use snowthrower on a roof.

22. If a foreign object is hit or snowthrower vibrates

abnormally, stop engine by turning key to OFF and wait for all moving parts to stop. Pull wire off spark plug and check snowthrower immediately for possible damage, an obstruction or loose parts. Vibration is generally a sign of trouble. Repair any damage before starting engine and operating snowthrower again.
