Checking Oil Level
CAUTION:
engine. You must, however, check the oil level prior
to operating the snow thrower. Running the engine
with insufficient oil can cause serious engine
damage and void the engine warranty.
NOTE: Be sure to check the engine on a level surface with the
engine stopped.
1. Remove the oil filler cap/dipstick and wipe the dipstick clean. See
Fig. 3-9.
Fill
between
high
and low
marks
2. Insert the cap/dipstick into the oil filler neck,
screw it in.
3. Remove the oil filler cap/dipstick. If the level is low, slowly add
oil until oil level registers between high (H) and low (L), Fig.
3-9. Refer to the Engine Maintenance section for correct oil
viscosity and engine oil capacity.
NOTE: Do not overfill. Overfilling with oil may result in
engine smoking, hard starting or spark plug fouling.
4. Replace and tighten cap/dipstick firmly before starting engine.
Tire Pressure
WARNING:
manufacturer's recommended psi. Equal tire pressure
should be maintained at all times. Excessive pressure
when seating beads may cause tire/rim assembly to
burst with force sufficient to cause serious injury.
Refer to sidewall of tire for recommended pressure.
The tires are over-inflated for shipping purposes.
Check the tire pressure before operating the snow thrower. Refer
to the tire side wall for tire manufacturer's recommended psi and
deflate (or inflate) the tires as necessary.
Note: Equal tire pressure is to be maintained at all times for
performance purposes.

Adjustments
Skid Shoes
The snow thrower skid shoes are adjusted upward at the factory
for shipping purposes. Adjust them downward prior to operating
the snow thrower.
CAUTION:
It is not recommended that you operate
this snow thrower on gravel as it can easily pick up
and throw loose gravel, causing personal injury or
damage to the snow thrower and surrounding
property.
For close snow removal on a smooth surface, adjust the skid
shoes so that the shave plate on the bottom of the auger
housing is just off the ground.
Adjust the skid shoes to a lower position to raise the shave plate
off the ground when clearing uneven areas, such as a ribbon
type driveway or a gravel driveway
NOTE: If you choose to operate the snow thrower on a gravel
surface, keep the skid shoes in position for maximum clearance
between the ground and the shave plate.
CAUTION:
Operating a snow thrower equipped
with steel skid shoes may result in damage to
natural stone paver surfaces (e.g. sandstone,
bluestone, limestone). Refer to the Replacement
Parts or Attachments & Accessories sections for
information on available polymer skid shoes.
To adjust the skid shoes:
1. Adjust skid shoes by loosening the six (three on each side) hex
nuts, washers, and carriage bolts securing the skid shoes
to the auger housing. Refer to Fig. 3-10.
