SAFETY

Any power equipment can cause injury if operated improperly or if the user does not understand how to operate the equipment. Exercise caution at all times, when using power equipment.

• Read this owner's manual carefully and know how

to operate your snow thrower and how to stop the unit and disengage the controls quickly.

• Never allow children to operate the equipment.

• Never allow adults to operate the equipment

without proper instruction.

• Keep the area of operation clear of all persons,

especially small children, and pets.

• Thoroughly inspect the area where the equipment

is to be used and remove all door mats, sleds, boards, wires and other foreign objects.

• Disengage all clutches and shift into neutral before

starting engine.

• Do not operate equipment without wearing ad-

equate 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 the rear

weight 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 and adjustment or repair.

• Do not place hand or feet near rotating parts. Keep

clear of the discharge opening at all times.

• Use extreme caution when operating on or crossing

gravel surfaces.

• 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.

• 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 transport-

ing 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 27 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 enclo-

sures, automobiles, window wells, drop offs etc. without proper adjustment of the snow thrower discharge angle.

• Never direct discharge at bystanders or allow

anyone in front of the snow thrower.

• Never run the snow thrower into material at high

speeds.

• Do not overload the machine capacity by attempt-

ing to clear snow at too fast a rate.

• Never operate the machine at high transport speed

on slippery surfaces. Look behind and use care when backing.

• Watch for traffic and stay alert when crossing or

operating near roadways.

• Disengage power to the snow thrower when trans-

porting 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.)

• Never operate the snow thrower without good

visibility or light.

panel to the disengaged (down) position.

• Screw the trunnion onto the end of the snow

thrower engagement rod as shown in figure 11.

was connected) underneath the right hand side the tractor, just to the inside of the suspension arm. If there is an extension attached to the clutch lever, the extension, bolt and nut must be removed and stored with the mower deck. IMPORTANT: Re-attach the extension to the clutch lever before reinstalling the mower deck.
