SAFETY
184045 |
Read and understand the operating instructions before using.
Keep the area of operation clear of all persons, especially small children and pets.
Thoroughly inspect the area to be cleared and remove all door mats, sleds, boards, wires and other foreign objects. Use extreme caution when operating on or crossing gravel surfaces. Never direct discharge at bystanders or allow anyone in front of the snow thrower.
199682 |
Do not place hands near rotating parts. Keep clear of the discharge opening at all times.
•Never allow children to operate the equipment.
•Never allow adults to operate the equipment without proper instruction.
•Disengage all clutches and shift into neutral before starting engine.
•Do not operate equipment without wearing adequate winter outer garments.
•Wear substantial footwear which will protect feet and improve footing on slippery surfaces.
•Check fuel before starting the engine. Do not remove the fuel cap or fill the fuel tank while the engine
is running or hot. Do not fill the fuel tank indoors. Gasoline is an extremely flammable fuel.
•Make sure the snow thrower height is adjusted to clear the type surface it will be used on.
•Do not use the snow thrower without wheel weights attached to the tractor.
•Never make any adjustments while the engine is running.
•Always wear safety glasses or eye shield during operation or while performing adjustment or repair.
•Do not place hands or feet near rotating parts. Keep clear of the discharge opening at all times.
•Do not carry passengers.
•After striking a foreign object, stop the engine, remove the wire from the spark plug and then thoroughly inspect the snow thrower for damage. Repair any damage before restarting and operating the snow thrower.
•If the snow thrower starts to vibrate abnormally, stop the engine immediately and check for the cause.
Vibration is generally a warning of trouble.
•Stop the engine whenever you leave the operating position, before unclogging the snow thrower or making any adjustments or inspections.
199683 |
Do not place feet near rotating parts.
•Take all possible precautions when leaving the unit unattended. Disengage the attachment clutch lever or switch, lower the snow thrower, shift into neutral, set the parking brake, stop the engine and remove the key.
•When cleaning, repairing or inspecting, make certain all moving parts have stopped. Disconnect the spark plug wire and keep it away from the plug to prevent accidental starting.
•Do not run engine indoors except when transporting the snow thrower in or out of the building. Open the outside doors. Exhaust fumes are dangerous.
•Do not clear snow across the face of slopes. Exercise extreme caution when changing direction on slopes.
Do not attempt to clear steep slopes. Refer to the slope guide on page 35 of this manual.
•Never operate the snow thrower without guards, plates or other safety protection devices in place.
•Never operate the snow thrower near glass enclosures, automobiles, window wells, drop offs etc. without proper adjustment of the snow thrower discharge angle.
•Never run the snow thrower into snow at high speeds.
•Do not overload the snow thrower capacity by attempting to clear snow at too fast a rate.
•Never operate the snow thrower at high transport speed on slippery surfaces. Look behind and use care when backing up.
•Watch for traffic and stay alert when crossing or operating near roadways.
•Disengage power to the snow thrower when transporting or when not in use.
•Use only attachments and accessories approved by the manufacturer of the snow thrower (such as wheel weights, counter weights, cabs etc.)
