Periodic adjustment of the cables may be required due to
normal stretch and wearon the belts. To check for correct
adjustment, the control lever must be in the full forward
position, resting on the plastic bumper. The control cables
are conectiy adjusted when the center of the "2" Fitting is
in the center of the hole and there is no droop in the cable
(See Fig.
22)..
If adjustment is necessary:
• Push the cable through the spring (See Fig, 23) to
expose the threaded portion of the cable.
• Hold the square end of the threaded portion with
pliers and adjust the locknut in or out until the excess
slack is removed.
• Pull the cable back through the spring and connect
the cable.
• Do the same for the other lever cable.
NOTE: Whenever the track drive or auger belts are
adjusted or replaced, the cables will need to be adjusted ,

the belts due to wear or stretch, proceed as follows:
TRACK DRIVE BELT (See Fig. 25)
The track drive bell has constant spring pressure and
does not require adjustment. Check the clutch control
cable adjustment before replacing the belt.
Replace the track drive belt if it is still slipping (see To
Replace Belts par agraph on page 19).
AUGER DRIVE BELT (See Fig. 25)
If your snow thrower will not discharge snow, check the
control cable adjustment. If it is correct, then check the
condition of the auger drive belt . It may be loose or dam­
aged. If it is damaged, replace it. See To Replace Belts
paragraph on page 19. If the auger drive belt is loose,
adjust as follows:
• Disconnect the spark plug wire,
• Remove the belt cover,
• Loosen the nut on the idler pulley (See Fig. 24) and
move the pulley toward the belt about 1/8".
• Tighten the nut
• Press the auger drive lever. Checkthe tension on the
bell (opposite Idler pulley). The belt should deflect
about 1/2" with moderate pressure (See Fig. 24).
NOTE; You may have to move the idler pulley more than
once to obtain the correct tension
• Replace the belt cover.
• Check the clutch control cable adjustment.
• Reconnect the spark plug wire.
