TO ADJUST TRACK
Ifthe snow throwerdoes not move forward evenly and the
track slips slightly, you need to check the track as follows:
® Pull up gently on the center of the track near the
center.
• Measure the distance between the track and the top
of the track support frame (See Fig.. 38). The dis-
tance should not be more than one and one quarter
(1-I/4) inches.
If the distance is greater, you need to adjust the track as
follows:
e Loosen or tighten the adjusting bolt at the rear of the
track support frame (See Fig 38) to obtain the
proper distance between the track and the track
support frame.
• Adjust the track on the opposite side in the same
manner.
