Making
Adjustments
WARNING
Read, understand,
and follow all instruc-
tions and warnings
on the machine and
in this manual before
operating.
Never attempt to
make any adjust-
ments while the
engine is running,
except where speci-
fied in operator’s
manual.
Run the engine
completely dry of
gasoline before
tipping snowthrower.
Shift Rod
If the full range of speeds (forward and reverse) cannot
be achieved, refer to Figure 5-1 and adjust the shift rod
as follows:
1. Looking underneath the handle panel, note which
of the three holes in the shift lever the ferrule is
inserted into. Also note the direction of insertion.
Then remove the internal cotter pin and flat washer
from the ferrule and withdraw the ferrule from the
shift lever. See Figure 5-1.
2. Place shift lever in sixth (6) position or fastest
forward speed.
3. Push shift rod and shift arm assembly down sharply,
as far as it will go to put the drive into the fastest
forward position.
4. As necessary, rotate the ferrule up or down the shift
rod until the ferrule lines up with the hole from which
it was earlier removed. See Figure 5-1.
5. From the direction noted earlier, insert the ferrule
into the proper hole.
6. Reinstall the washer and the internal cotter pin.
Drive Control
WARNING: Run the engine com-
pletely dry of gasoline before tipping
snowthrower.
Refer to the Final Adjustment section of the Set-Up
instructions to adjust the drive control. To further check
the adjustment, proceed as follows:
1. Tip the snow thrower forward, allowing it to rest on
the auger housing.
2. Remove the frame cover underneath the snow
thrower by removing the self-tapping screws. See
Figure 5-2.
3. With the wheel drive control released, check if there
is clearance between friction wheel and drive plate in
all positions of the shift lever. See Figure 5-3.
4. With the drive control lever engaged, check if the
friction wheel solidly contacts the drive plate. See
Figure 5-3. If not, adjust as follows:
a. Loosen the jam nut on the drive cable and thread
the cable in or out as necessary.
b. Retighten the jam nut to secure the cable when
correct adjustment is reached.
5. Reassemble the frame cover.
