Skid Shoe
The space between the shave plate and the ground can
be adjusted by raising or lowering the skid shoes.
For close snow removal, as when using on a smooth
concrete or asphalt driveway, place the skid shoes in
the low position. Use the middle or high position when
the area to be cleared is uneven. When operating on
gravel, always put skid shoes in the high position.
See Figure 15.
Adjust skid shoes as follows:
• Loosen, but do not remove, the hex flange locknuts
which fasten the skid shoe to the auger housing.
• Raise or lower the skid shoe to desired position.
• Retighten the hex nuts loosened earlier.
NOTE: Make certain the bottom surface of skid shoe is
flat against the ground to avoid uneven wear .
• Repeat on the other side of the snow thrower.

SECTION 6: 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 hardware to
make sure these are tight.
Lubrication
Drive and Shifting Mechanism
• At least once a season or after every 25 hours of
operation, remove rear cover. Lubricate any chains,
sprockets, gears, bearings, shafts, and the shifting
mechanism at least once a season. Use engine oil
or a spray lubricant. Refer to Figure 14.
IMPORTANT: Avoid spillage of oil on rubber friction
wheel and aluminum drive plate.
Gear Shaft
• Lubricate the gear shaft with 6-in-1 grease (part
number 737-0170) at least once a season, or after
every 25 hours of operation. Refer to Figure 14.
IMPORTANT: Keep all grease and oil off the rubber
friction wheel and drive plate.
Engine
Refer to the engine manual for instructions.
Gear Case
The gear case is lubricated with grease at the factory
and it does not require checking.
• If disassembled for any reason, lubricate with 2
ounces of Shell Alvania grease EPR00, part
number 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.
Auger Shaft
• At least once a season, remove the shear pins from
the auger shaft and spray lubricant inside the shaft.
See Figure 16.
