1. Disconnect and lockout power to the grinder!
2. Install the rear idler such that its inside-bearing surface is approximately 0.06 inches out from
the wheel support. Secure the wheel with locking set screw.
3. Install the upper wheel such that its inner bearing surface is approximately 0.06 inches out
from its bearing support. Secure the wheel with locking set screw.
4. Loosen the retaining nut that locks the upper idler wheel adjusting screw. Using screw,
adjust the upper idler wheel until a straight line representing the plane passing through the
center of the upper idler exactly passes through the center of the contact wheel. This line
represents the center of belt travel.
Note: Make certain that the bearing support is against the screw end.
5. Project a line from the upper idler outside rim to the outside rim of the rear idler. Adjust the
tracking control until the wheels are on the exact same plane. That is when their radial
centers are aligned.
6. Repeat step 3 and 4 until both conditions are satisfied. That is the upper and rear idlers are
aligned to each other and both wheels are aligned to the contact wheel.
7. Tighten the locking nut.
8. Install a new abrasive belt. Roll the belt manually to assure that it will maintain coarse
tracking. If the belt does not track manually, repeat the prior steps until it does. If after
repeating these steps the belt still will not track the machine requires other maintenance
and/or one or both idler wheels require replacing. The wheels should be replaced in pairs.
9. Connect power to and then start the grinder.
10. Watch the belt tracking and stop the machine immediately if the belt starts to track off of the
wheels. The belt may track to one side or the other but should not start to run off of the
wheels.
11. Adjust the tracking control will sweep the belt across the face of the contact wheel. At least
1/2" adjustment in both directions from center should be possible.
