Making Adjustments - MTD 614E Operator's Manual

SECTION 6: MAKING ADJUSTMENTS
WARNING:
adjustments while the engine is running,
except where specified in operator's
manual.
Tire Pressure
(Pneumatic Tires)
• The tires are overinflated for shipping purposes.
Before operating check tire pressure and reduce
pressure to between 15psi 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
clutch and shift lever, proceed as follows:
• With the engine off, move the shift lever all the way
forward to the highest speed. With the traction
control lever released, push the snow thrower
forward. The unit should roll forward. Then engage
the traction control grip. The 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 the
wheels should keep turning.
• If you have 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 clutch 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:
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 so that it rests on the auger
housing. See Figure 17.
• Remove the frame cover underneath the snow
thrower by removing six self-tapping screws.
• When the traction control is released, there must be
clearance between the friction wheel and the drive
plate in all positions of the shift lever.
Never attempt to make any
