WARNING: Always disconnect spark plug wire
and place it where it can not con tact plug in order to pre vent ac ci den tal start ing when setting up, trans port ing, ad just ing or making re pairs.
WARNING: This snow thrower is for use on
sidewalks, driveways and other ground level sur­faces. Caution should be exercised while using on sloping surfaces. Do not use snow thrower on surfaces above ground level such as roofs of residences, garages, porch es or other such structures or buildings.
Training
1. Read, understand and follow all instructions on the machine and in the manual(s) before operating this unit. Be thoroughly familiar with the controls and the proper use of the equipment. Know how to stop the unit and disengage the controls quickly.
2. Never allow children to operate the equipment. Never allow adults to operate the equipment without proper instruction.
3. Keep the area of operation clear of all persons, par­ticularly small children.
4. Exercise caution to avoid slipping or falling, especially when operating the snow thrower in reverse.
Preparation
1. Thoroughly inspect the area where the equipment is to be used and remove all doormats, sleds, boards, wires, and other foreign objects.
2. Ensure the control bar is released before starting the engine.
3. Do not operate the equipment without wearing adequate winter garments. Avoid loose fitting clothing that can get caught in moving parts. Wear footwear that will improve footing on slippery surfaces.
4. Handle fuel with care; it is highly flammable (a) Use an approved fuel container. (b) Never add fuel to a running engine or hot engine. (c) Fill fuel tank outdoors with extreme care. Never fill

ents, and certain vehicle com po nents contain or emit chem i cals known to the State of Cal i for nia to cause can cer and birth defects or oth er re pro­duc tive harm.
(d) Never fill containers inside a vehicle or on a truck or
trailer bed with a plastic liner. Always place containers on the ground, away from your vehicle, before filling.
(e) When practical, remove gas-powered equipment
from the truck or trailer and refuel it on the ground. If this is not possible, then refuel such equipment on a trailer with a portable container, rather than from a gasoline dispenser nozzle.
(f) Keep the nozzle in contact with the rim of the fuel
tank or container opening at all times, until refueling is complete. Do not use a nozzle lock-open device.
(g) Replace gasoline cap securely and wipe up spilled
fuel.
(h) If fuel is spilled on clothing, change clothing

Filling the Engine with Oil
ENGINE
See engine manual.
LUBRICATION
NOTE: Although multi-viscosity oils (5W30, 10W30 etc.)
improve starting in cold weather, these multi-viscosity oils will result in increased oil consumption when used above 32°F. Check your engine oil level more frequently to avoid
possible engine damage from running low on oil.
Change the oil after every 25 hours of operation or at least once a year if the snow thrower is not used for 25 hours in one year.
Check the crankcase oil level before starting the engine and after each five (5) hours of continuous use. Tighten oil fill cap / dipstick securely each time you check the oil level.
1. Move the snowthrower to a level surface.
2. Clean around the dipstick (Figure 7). NOTE: Dipstick location may vary depending on engine
type.
3. Remove either side mounted filler cap dipstick or high oil fill dipstick and wipe it clean.

OPERATION
Operation
NOTE: Determine the left and right sides of the machine
from the normal operating position.
• Gasoline is extremely flammable and explosive. A fire or explosion from gasoline can burn you and others.
• To prevent a static charge from igniting the gaso­line, place the container and/or snowthrower on the ground before filling, not in a vehicle or on an object.
• Fill the tank outdoors when the engine is cold. Wipe up spills.
• Do not handle gasoline when smoking or around an open flame or sparks.
• Store gasoline in an approved fuel container, out of the reach of children.
• Do not tip the snowthrower with fuel in the fuel tank.
The operation of any snow thrower can result in foreign objects thrown into the eyes, which can result in severe eye damage. Always wear safety glasses or eye shields while operating
your snow thrower or performing any ad just­ ments or repairs. We recommend standard safe ty glasses or a wide vision safety mask worn over spectacles.
IMPORTANT: Know how to operate all controls before adding fuel or attempting to start the engine.
IMPORTANT: Do not use E85 blended fuels. This engine is not E20/E30/E85 compatible. Alternative fuels with high alcohol content can cause hard starting, poor engine performance, and may cause internal engine damage.
NOTE: For best results, purchase only the quantity of gasoline that you expect to use in 30 days. Otherwise, you may add fuel stabilizer to newly purchased gasoline to keep it fresh for up to 6 months.
Checking the Engine Oil Level
1. Move the snowthrower to a level surface.
2. Clean around the dipstick (Figure 9). NOTE: Dipstick location may vary depending on engine
type.
3. Remove either side mounted filler cap dipstick or high oil fill dipstick and wipe it clean.
Fill if oil is below “Add” on the
GLSVWLFN
Fill if oil is below letter “L” on the
¿OOHUFDS
Filling the Fuel Tank
Fill the fuel tank with fresh, unleaded gasoline (minimum 87 AKI octane rating) (Figure 8).
Figure 8
IMPORTANT: Do not add oil to the gasoline.
Figure 9
1. Oil filler cap/dipstick
4. Insert the dipstick into the filler neck and turn clockwise until fully seated. Then remove the dipstick by turning it counter-clockwise.
5. Fill oil to "FULL" on dipstick with the recommended oil.
