the adjustments on the Model g0659 allow the
upper and lower wheels to be tilted relative to
each other to reach coplanarity.
To adjust the wheel coplanarity:
1. detension the blade.
2. Behind the upper wheel, loosen the cap
screws indicated in figure 56. only slightly
loosen the upper two cap screws. this mini-
mizes lateral movement of the upper wheel
and ensures accurate adjustments.
3. through the lower wheel, loosen the three
hex nuts indicated in figure 57. only slightly
loosen the upper two hex nuts. this again
minimizes lateral movement of the lower
wheel and ensures accurate adjustments.
4. locate the set screws indicated in figures
56–57. Adjusting these set screws changes
the angle of the wheels.
5. properly tension the blade (page 26).
6. Again use your coplanarity gauge to check
the tilt of the upper and lower wheels. if pos-
sible, have an assistant hold the gauge while
you make adjustments to the set screws.
Adjust as necessary until the gauge touches
the top and bottom of both wheels, as shown
in
figure 58.
Note: The two set screws on the lower wheel
assembly must be adjusted in equal incre-
ments to ensure proper wheel alignment.
