To remove shave plate:
Remove the carriage bolts and hex nuts which attach it to 3.
the auger housing.
Reassemble new shave plate, making sure heads of carriage 4.
bolts are to the inside of housing. Tighten securely.
Lubrication
Gear Shaft
The gear (hex) shaft should be lubricated at least once a season
or after every twenty-five (25) hours of operation.
Allow the engine to run until it is out of fuel.1.
Carefully pivot the snow thrower up and forward so that it 2.
rests on the auger housing.
Remove the frame cover from the underside of the snow 3.
thrower by removing the self-tapping screws which secure
it. Refer to Fig 7-3.
Apply a light coating of engine oil (or 3-in-1 oil) to the hex 4.
shaft. See Fig. 6-2.
NOTE: When lubricating the hex shaft, be careful not to get
any oil on the aluminum drive plate or the rubber friction
wheel. Doing so will hinder the snow thrower’s drive
system. Wipe off any excess or spilled oil.
Wheels
At least once a season, remove both wheels. Clean and coat the
axles with a multipurpose automotive grease before reinstalling
wheels.
Auger Shaft
At least once a season, remove the shear pins from the auger
shaft. Spray lubricant inside the shaft and around the spacers and
the flange bearings found at either end of the shaft.
See Fig. 6-3.

Chute Assembly
Refer to the Assembly & Set-up section for instructions on
adjusting the chute assembly.
Skid Shoes
Refer to the Assembly & Set-up section for instructions on
adjusting the skid shoes.
Drive Control
When the drive control is released and in the disengaged “up”
position, the cable should have very little slack. It should NOT be
tight.
NOTE: If excessive slack is present in the drive cable or if the snow
thrower’s drive is disengaging intermittently during operation,
the cable may be in need of adjustment.
Check the adjustment of the drive control as follows:
With the drive control released, push the snow thrower 1.
gently forward. The unit should roll freely.
Engage the drive control and gently attempt to push the 2.
snow thrower forward. The wheels should not turn. The
unit should not roll freely.
With the drive control released, move the shift lever back 3.
and forth between the R2 position and the F6 position
several times. There should be no resistance in the shift
lever.
If any of the above tests failed, the drive cable is in need of
adjustment. Proceed as follows:
Loosen the lower hex screw on the drive cable bracket. See 1.
Fig. 6-5.
Position the bracket upward to provide more slack (or 2.
downward to increase cable tension).
Retighten the upper hex screw. 3.
Repeat Drive Control Test to verify proper adjustment has 4.
been achieved.

Adjustments
Shift Cable
If the full range of speeds (forward and reverse) cannot be
achieved, adjust the shift cable as follows:
Place the shift lever in the fastest forward speed position.1.
Loosen the hex nut on the shift cable index bracket. See 2.
Fig. 6-4.
Pivot the bracket downward to take up slack in the cable. 3.
Retighten the hex nut.4.

Chute Rod Adjustment
If the chute fails to remain stationary during operation, increase
the preload on the chute control rod.
While preventing the chute control rod from turning
tighten the nut on the chute gearbox assembly. See Fig.
6-7.
If the chute directional control is difficult to crank, decrease the
preload by loosening the hex nut counterclockwise in ¼ turn
intervals.
Off-Season Storage
If the snow thrower will not be used for 30 days or longer, follow
the storage instructions below.
Lubricate the machine as instructed earlier in this section.1.
Store in a clean, dry area.2.
If storing the snow thrower in an unventilated area, 3.
rustproof the machine using a light oil or silicone to coat
the snow thrower.
Clean the exterior of the engine and the snow thrower.4.
NOTE: Refer to the Engine Operator’s Manual for information on
storing your engine.
