Operating Tips
NOTE: Allow the engine to warm up for a few minutes
as the engine will not develop full power until it reaches
operating temperature.
For most efficient snow removal, remove snow
immediately after it falls.
Discharge snow downwind whenever possible.
Slightly overlap each previous swath.
Set the skid shoes 1/4" below the scraper bar for
normal usage. The skid shoes may be adjusted
upward for hard-packed snow.
NOTE: It is not recommended that you operate this
snow thrower on gravel as loose gravel can be easily
picked up and thrown by the auger causing an injury or
damage to the snow thrower.
WARNING: The temperature of muffler and
surrounding areas may exceed (150
o
F (65
o
C). Avoid these areas.
12
If for some reason, you have to operate the snow
thrower on gravel, keep the skid shoe in the highest
position for maximum clearance between ground
and shave plate.
Clean the snow thrower thoroughly after each use.
Chute Clean-Out Tool
The chute clean-out tool is conveniently fastened to the
rear of the auger housing with a mounting clip. Never
use your hand to clean a clogged chute.
1. Release both the auger control lever and the
traction/auger control lock lever.
2. Stop the engine by removing the ignition key.
3. Remove the clean-out tool from the clip which
secures it to the rear of the auger housing. See

SECTION 4: MAINTAINING YOUR SNOW THROWER
General Recommendations
Always observe safety rules when performing any
maintenance.
The warranty on this snow thrower does not cover
items that have been subjected to operator abuse
or negligence. To receive full value from the
warranty, operator must maintain the snow thrower
as instructed in this manual.
Some adjustments will have to be made
periodically to maintain your unit properly.
Periodically check all fasteners and make sure
these are tight.
Engine
Refer to the separate engine manual packed with your
unit for all engine maintenance.
Lubrication
Engine: Refer to the separate engine manual
packed with your unit.
Drive Mechanism: Once a season or after every
25 hours of operation, remove rear frame cover and
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 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™
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. Be sure the vent plug
is free of grease in order to relieve pressure.
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
snowthrower should be lubricated with a light oil
once a season. If the unit is equipped with grease
fittings, use a grease gun to lubricate these.
Drive/Auger Control Lock: The cam on the ends
of the control rods which interlock the traction drive
and auger drive clutches must be lubricated at least
once a season or every 25 hours of operation using
a multi-purpose automotive grease. The cam can
be accessed beneath the handle panel
