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:
1. With the drive control released, push the snow thrower
gently forward. The unit should roll freely.
2. Engage the drive control and gently attempt to push the
snow thrower forward. The wheels should not turn. The
unit should not roll freely.
If any of the above tests failed, the drive cable is in need of
adjustment. Proceed as follows:
1. Shut off the engine as instructed in the separate engine
manual.
2. Loosen the lower hex screw on the drive cable bracket. See
Figure 6-7.
3. Position the bracket upward to provide more slack (or
downward to increase cable tension).
4. Retighten the upper hex screw.
5. Check the adjustment of the drive control as described
above to verify proper adjustment has been achieved as
follows:
a. With the drive control released, move the shift lever
back and forth between the R2 position and the F6
position several times. There should be no resistance
in the shift lever.

assembly on the chute rotation assembly. See Figure 6-8.
Figure 6-8
2. Pull out the chute control rod until the hole in it lines up
with the hole furthest from the chute assembly on the
chute rotation assembly.
3. Reinsert the hairpin clip through this hole and the chute
control rod. See Figure 6-8.
Off-Season Storage
If the snow thrower will not be used for 30 days or longer, follow
the storage instructions below.
1. Run the engine until the fuel tank is empty and it stops due
to lack of fuel. Do not attempt to pour fuel from the engine.
2. Lubricate the machine as instructed earlier in this section.
3. Store in a clean, dry area.
4. If storing the snow thrower in an unventilated area,
rustproof the machine using a light oil or silicone to coat
the snow thrower.
5. Clean the exterior of the engine and the snow thrower.
IMPORTANT: When storing unit or when it is not being
serviced, it is to remain in the operating position with both
wheel and auger housing on the ground.
NOTE: Refer to the Engine Operator's Manual for
information on storing your engine.
