Adjusting the Traction Control
If traction control does not engage or it slips during
operation, an adjustment is required.
1. Move the traction control to the Disengaged
position.
2. Loosen the retainer securing the V-belt cover and
pivot the cover open (Figure 33).
3. To increase the cable tension, loosen the front
cable jam nut and tighten the back cable jam nut
(Figure 36) until a force of 7 to 9 lb is required to
engage the traction control. Measure the force at the
control knob.

Leveling the Rear Drum to the
Reel
1. Position the machine on a flat, level surface,
preferably a precision steel work plate.
2. Place a 1/4 x 1 inch (0.6 x 2.5 cm) flat steel strip,
approximately 29 inches (73.6 cm) long, under the
reel blades and against the front edge of the bedknife
to prevent the bedbar from resting on the work
surface.
3. Raise the front roller so only the rear drum and reel
are on the surface.
4. Firmly press down on the machine above the reel so
all reel blades contact the steel strip.
5. While pressing down on the reel, slide a feeler gauge
under one end of the drum, then check the other
end of the drum.
If there is a gap between the drum and the work
surface, greater than 0.010 inch (.025 cm), on either
end, adjust the drum (proceed to step 6). If the gap
is less than 0.010 inch (.025 cm) no adjustment is
required.
6. Remove the rear belt cover from the right side of
the machine (Figure 37).
