the operator’s position and shut off the engine. Wait
for ALL moving parts to stop before re-adjusting the
auger control.
1. With the engine running near top speed, move
shift lever to one of six FORWARD positions or two
REVERSE positions. Select a speed appropriate for
the snow conditions that exist.
The muffler, engine
and surrounding
areas become hot
and can cause a
burn. Do not touch.
2. Squeeze drive control against the right handle and
the snow thrower will move. Release it and the drive
motion will stop.
7. To readjust the control cable, loosen the upper hex
nut on the auger cable bracket.
To Engage Augers
1. To engage augers and start snow throwing, squeeze
the left hand auger control against the left handle.
Release to stop augers.
8. Position the bracket upward to provide more slack (or
downward to increase cable tension). See Figure 12.
9. Retighten the upper hex nut.
10.Repeat Auger Control Test to verify proper adjustment
has been achieved.
2. While the auger control is engaged, squeeze the
drive control to move, release to stop. Do not shift
speeds while the drive is engaged.
When selecting a
Drive Speed, use the
slower speeds until
you are comfortable
and familiar with the
operation of the snow
thrower.
NOTE: This same lever also locks auger control so you
can turn the chute control without interrupting the snow
throwing process.
3. Release the auger control; the interlock mechanism
should keep the auger control engaged until the drive
control is released.
4. Release the drive control to stop both the augers and
the wheel drive. To stop the auger, both levers must
be released.
NEVER reposition the
shift lever (change
speeds or direction
of travel) without first
releasing the drive
control and bringing
the snow thrower
Figure 12
to a complete stop.
Doing so will result in
premature wear to the
snow thrower’s drive
system.

Chute Control
Figure 13
Once a season or every 25 hours of operation, whichever
is earlier, check whether the four-way chute control™
cables have slackened. If the chute does not rotate
fully or its pitch cannot be moved up or down, the chute
control cables will have to be adjusted.
WARNING
Read, understand,
and follow all instruc-
tions and warnings
on the machine and
in this manual before
operating.
To adjust these cables, proceed as follows:
1. To tighten cable, loosen the top nut and tighten the
bottom nut on the cable.
2. Adjust equally on both sides by working on both
cables. See Figure 14.
Drive Control & Shift Lever
Never attempt to
make any adjust-
ments while the
engine is running,
except where speci-
fied in operator’s
manual.
When the drive control is released and in the disengaged
“up” position, the cable should have very little slack. It
should NOT be tight.
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.
Figure 14
3. 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.
4. If any of the above tests failed, the drive cable is in
need of adjustment. Proceed as follows:
5. Loosen the lower hex nut on the drive cable bracket.
See Figure 15.
6. Position the bracket upward to provide more slack (or
downward to increase cable tension).
7. Retighten the lower hex nut.
You can also check the adjustment as follows:
1. With the snow thrower tipped forward (be certain to
drain gasoline or place plastic film under the gas cap if
the snow thrower has already been operated), remove
the frame cover underneath the snow thrower by
removing the self-tapping screws. Refer to step 2 on
page 17.
