SECTION 5: MAKING ADJUSTMENTS
WARNING: NEVER attempt to make any
adjustments while the engine is running,
except where specified in the operator’s
manual.
Tire Pressure (Pneumatic Tires)
• The tires are over-inflated for shipping purposes.
Before operating, check tire pressure and reduce, if
necessary, to between 15 psi and 20 psi.
NOTE: If the tire pressure is not equal in both tires, the
unit may pull to one side or the other.
Traction Control and Shift Lever
• To check the adjustment of the traction control and
shift lever, proceed as follows:
• With the engine off, move the shift lever all the way
forward to sixth (6) position. With the traction
control released, push the snow thrower forward.
The unit should move forward freely. Then engage
the traction control grip. Wheels should stop
turning.
• Now release the traction control grip, and push the
unit again.
• Move the shift lever back to the fast reverse
position, then all the way forward again. There
should be no resistance in the shift lever, and
wheels should keep turning.
• If you feel resistance when moving the shift lever or
the wheels stop when they should not, loosen the
jam nut on the traction control cable and unthread
the cable one turn.
• If the wheels do not stop when you engage the
traction control grip, loosen the jam nut on the
traction control cable and thread the cable in one
turn. Recheck the adjustment and repeat as
necessary. Tighten the jam nut to secure the cable
when correct adjustment is reached.
WARNING: Drain the gasoline out of snow
thrower engine, place a piece of plastic film
under the gas cap to avoid spillage before
beginning the job.
To test further for correct adjustment, if necessary,
proceed as follows:
• Tip the snow thrower forward, allowing it to rest on
the auger housing. See Figure 11.
Figure 11
• Remove the frame cover underneath the snow
thrower by removing six self-tapping screws.
• With the traction control released, there must be
clearance between the friction wheel and the drive
plate in all positions of the shift lever.
• With traction control engaged, the friction wheel
must contact the drive plate. See Figure 12.
Figure 12
If adjustment is necessary:
• Loosen the jam nut on the traction drive cable and
thread the cable in or out as necessary.
• Retighten the jam nut to secure the cable when
correct adjustment is reached.
• Reassemble the frame cover.
NOTE: If you placed plastic film under the gas cap, be
certain to remove it before operating the snow thrower.
