SAFE OPERATION PRACTICES
SAFE HANDLING OF GASOLINE
To avoid personal injury or property damage use extreme care
in handling gasoline. Gasoline is extremely flammable and the
vapors are explosive. Serious personal injury can occur when
gasoline is spilled on yourself or your clothes which can ignite.
Wash your skin and change clothes immediately.
1. Use only an approved gasoline container.
2. Extinguish all cigarettes, cigars, pipes and other sources of
ignition.
3. Never fuel machine indoors.
4. Never remove gas cap or add fuel while the engine is hot or
running.
5. Allow engine to cool at least 5 minutes before refueling.
6. Never over fill fuel tank. Fill tank to no more than ½ inch
below bottom of filler neck to provide space for fuel
expansion.
7. Replace gasoline cap and tighten securely.
8. If gasoline is spilled, wipe it off the engine and equipment.
Move machine to another area. Wait 5 minutes before
starting the engine. If fuel is spilled on clothing, change
clothing immediately.
9. Never store the machine or fuel container inside where there
is an open flame, spark or pilot light (e.g. furnace, water
heater, space heater, clothes dryer etc.).
10. Allow machine to cool at least 5 minutes before storing.
11. 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.
12. If possible, 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.
13. Keep the nozzle in contact with the rim of the fuel tank or
container opening at all times until fueling is complete. Do
not use a nozzle lock-open device.
OPERATION
1. Do not put hands or feet near rotating parts, in the auger
housing or chute assembly. Contact with the rotating parts
can amputate hands and feet.
2. The auger control lever is a safety device. Never bypass its
operation. Doing so makes the machine unsafe and may
cause personal injury.
3. The control levers must operate easily in both directions
and automatically return to the disengaged position when
released.
4. Never operate with a missing or damaged chute assembly.
Keep all safety devices in place and working.
5. Never run an engine indoors or in a poorly ventilated area.
Engine exhaust contains carbon monoxide, an odorless and
deadly gas.
6. Do not operate machine while under the influence of alcohol
or drugs.
7. Muffler and engine become hot and can cause a burn. Do not
touch. Keep children away.
8. Exercise extreme caution when operating on or crossing
gravel surfaces. Stay alert for hidden hazards or traffic.
9. Exercise caution when changing direction and while
operating on slopes. Do not operate on steep slopes.
10. Plan your snow-blowing pattern to avoid discharge towards
windows, walls, cars etc. Thus, avoiding possible property
damage or personal injury caused by a ricochet.
11. Never direct discharge at children, bystanders and pets or
allow anyone in front of the machine.
12. Do not overload machine capacity by attempting to clear
snow at too fast of a rate.
13. Never operate this machine without good visibility or light.
Always be sure of your footing and keep a firm hold on the
handles. Walk, never run.
14. Release auger control lever to disengage power to the auger
when transporting or not clearing snow.
15. Never operate machine at high transport speeds on slippery
surfaces. Look down and behind and use care when backing
up.
16. After striking a foreign object or if the machine should start
to vibrate abnormally, stop the engine, remove the safety
key or disconnect spark plug wire. Inspect thoroughly for
damage. Repair any damage before starting and operating.
4
SAFE OPERATION PRACTICES
17. Disengage all control levers, stop engine, remove the
safety key or disconnect spark plug wire before you leave
the operating position (behind the handles). Wait until the
auger comes to a complete stop before unclogging the chute
assembly, making any adjustments, or inspections.
18. Never put your hand in the discharge or collector openings.
Always use the clean-out tool provided to unclog the
discharge opening. Do not unclog chute assembly while
engine is running. Shut off engine, remove the safety key or
disconnect spark plug wire. Remain behind handles until all
moving parts have stopped before unclogging.
19. Use only attachments and accessories approved by the
manufacturer (e.g. wheel weights, tire chains, cabs etc.).
20. When starting engine, pull cord slowly until resistance is felt,
then pull rapidly. Rapid retraction of starter cord (kickback)
will pull hand and arm toward engine faster than you can let
go. Broken bones, fractures, bruises or sprains could result.
21. If situations occur which are not covered in this manual,
use care and good judgment. Contact Customer Support for
assistance and the name of your nearest servicing dealer.
CLEARING A CLOGGED DISCHARGE CHUTE
Hand contact with the rotating impeller or auger inside the
discharge chute is the most common cause of injury associated
with snow blowers. Never use your hand to clean out the
discharge chute.
To clear the chute:
1. SHUT THE ENGINE OFF!
2. Remove the safety key or disconnect spark plug wire.
3. Wait 10 seconds to be sure the impeller or auger has stopped
rotating.
4. Always use a clean-out tool, not your hands.
MAINTENANCE & STORAGE
1. Never tamper with safety devices. Check their proper
operation regularly. Refer to the maintenance and
adjustment sections of this manual.
2. Before cleaning, repairing, or inspecting machine, disengage
all control levers, stop the engine, remove the safety key or
disconnect spark plug wire. Wait until the auger comes to a
complete stop.
3. Check bolts and screws for proper tightness at frequent
intervals to keep the machine in safe working condition. Also,
visually inspect machine for any damage.
4. Do not change the engine governor setting or over-speed the
engine. The governor controls the maximum safe operating
speed of the engine.
5. Snow blower shave plates and skid shoes are subject to
wear and damage. For your safety protection, frequently
check all components and replace with original equipment
manufacturer’s (OEM) parts only. “Use of parts which do
not meet the original equipment specifications may lead to
improper performance and compromise safety!”
6. Check control levers periodically to verify they engage and
disengage properly and adjust, if necessary. Refer to the
adjustment section in this operators manual for instructions.
7. Maintain or replace safety and instruction labels, as
necessary.
8. Observe proper disposal laws and regulations for gas, oil, etc.
to protect the environment.
