_ WARNING: This symbol points out important safety instructions which, if not followed, could endangerthe personal safety and/or property of yourself and others. Read and follow all instructions in this manual
before attempting to operate this machine. Failure to comply with these instructions may result in personal
injury. When you see this symbol--heed its warning.
_ ARNING: Engine Exhaust, some of its constituents, and certain vehicle components contain or emitchemicals known to State of California to cause cancer and birth defects or other reproductive harm.
DANGER: This machine was built to be operated according to the rules for safe operation in this manual. As with
any type of power equipment, carelessness or error on the part of the operator can result in serious injury. This
machine is capable of amputating hands and feet and throwing objects. Failure to observe the following safety
instructions could result in serious injury or death.

machine and in the manual(s) before attempting to
assemble and operate. Keep this manual in a safe place
for future and regular reference and for ordering
replacement parts.
2. Be familiar with all controls and their operation. Know
how to stop the machine and disengage controls.
3. Never allow children under 14 years old to operate this
machine. Children 14 years old and over should read and
understand the operation instructions and safety rules in
this manual and should be trained and supervised by a
parent.
4. Never allow adults to operate this machine without
proper instruction.
5. Thrown objects can cause serious personal injury. Plan
your snow-throwing pattern to avoid discharge of material
toward roads, bystanders and the like.
6. Keep bystanders, helpers, pets and children at least 75
feet from the machine while it is in operation. Stop
machine if anyone enters the area.
7. Exercise caution to avoid slipping or falling, especially
when operating in reverse.
Preparation
1. Thoroughly inspect the area where the equipment is to
be used. Remove all doormats, newspapers, sleds,
boards, wires and other foreign objects, which could be
tripped over or thrown by the auger/impeller.
2. Always wear safety glasses or eye shields during
operation and while performing an adjustment or repair to
protect your eyes. Thrown objects which ricochet can
cause serious injury to the eyes.
3. Do not operate without wearing adequate winter outer
garments. Do not wear jewelry, long scarves or other
loose clothing, which could become entangled in moving
parts. Wear footwear which will improve footing on
slippery surfaces.
4. Use a grounded three-wire extension cord and
receptacle for all units with electric start engines.
5. Adjust collector housing height to clear gravel or crushed
rock surfaces.
6. Disengage all clutch levers before starting the engine.
7. Never attempt to make any adjustments while engine is

lubricate any chains, sprockets, gears, bearings,
and shafts with engine oil or lubricant spray.
IMPORTANT: Avoid oil spillage on rubber friction
wheel and aluminum drive plate.
• Hex Gear Shaft: Once a season, lubricate the hex
shaft with a penetrating oil, but not grease,
• Gear Case: The gear case is lubricated with
grease at the factory and does not require regular
lubrication. However, if disassembled for any
reason, lubricate with 2 ounces of Shell Alvania TM
grease (part # 737-0168). Before reassembling,
remove old sealant and apply new sealant.
IMPORTANT: Do not overfill the gear case, since
damage to the seals could result.
• Wheels: Once a season, remove the bolt from
each wheel and take the wheel off the axle. Apply a
multipurpose automotive grease on the shaft
before putting back the wheels.
• Shift Rod: Use a grease or light oil to lubricate the
rotating parts of the shift rod after 25 hours of
operation.
• Pivot Points: All pivoting points on the snow
thrower should be lubricated with a light oil once a
season.

Checking Oil Level
Before operating snow thrower, check the oil level by
following steps below.
NOTE: Although multi-viscosity oils (5W30, 10W30
etc.) improve starting in cold weather, these multi-
viscosity oils also result in higher oil consumption when
used above 32°F. Check your snow thrower's engine oil
level more frequently to avoid possible engine damage
from running low on oil.
1. With engine on level ground, oil must be to FULL
mark on dipstick. See Figure 16.
2. Stop engine and wait several minutes before
checking oil level. Remove oil fill cap and dipstick.
3. Wipe dipstick clean, insert it into oil fill hole and
tighten securely.
4. Remove dipstick and check. Ifoil is not up to the
FULL mark on dipstick, add oil.
