•
and prevent freeze up of auger/impeller.
Never store the machine or fuel container inside where there is an open
•
flame, spark or pilot light such as a water heater, furnace, clothes dryer
etc.
Always refer to the operator’s manual for proper instructions on
•
off-season storage.
Do not modify engine
To avoid serious injury or death, do not modify engine in any way. Tampering
with the governor setting can lead to a runaway engine and cause it to operate
at unsafe speeds. Never tamper with factory setting of engine governor.

bow-tie clips. If the auger should strike a foreign object or ice jam,
the snow thrower is designed so that the shear pins may shear. If the
augers will not turn, check to see if the pins have sheared. See Figure
11.
CAUTION
NEVER replace the auger shear pins with anything other than OEM
Part No. 738-04124A replacement shear pins. Any damage to the
auger gearbox or other components as a result of failing to do so will
NOT be covered by your snow thrower’s warranty.
WARNING
Always turn off the snow thrower’s engine and remove the key prior to
replacing shear pins.
NOTE: Allow the engine to warm up for a few minutes after starting.

ADJUSTMENTS
Shift Cable
If the full range of speeds (forward and reverse) cannot be achieved,
refer to the figure to the right and 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 Figure
2.
18.
Pivot the bracket downward to take up slack in the cable.
3.
Retighten the hex nut.
4.
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. Also,
if there is excessive slack in the drive cable or if the unit experiences
intermittent drive while using, the cable may need to be adjusted.
Check the adjustment of the drive control as follows:
With the drive control released, push the snow thrower gently
1.
forward. The unit should roll freely.
Engage the drive control and gently attempt to push the snow
2.
thrower forward. The wheels should not turn. The unit should not
roll freely.
With the drive control released, move the shift lever back and
3.
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 adjust-
4.
ment. Proceed as follows:
Loosen the lower hex bolt on the drive cable bracket. See Figure
5.
19.
Position the bracket upward to provide more slack (or downward
6.
