•
Check the nut (A) that secures the contact wheel to
its mount.
Ensure it is tightened to 10–15lbs. ft. (1.4–2 kg m)
of torque.
Monthly
•
Apply light machine oil to tracking assembly. Two
drops of oil will be sufficient.
•
Check the drive belt tension. If you can hear the
belt "slap" the frame when the drive motor starts,
the belt may require re-tensioning. Do this by
loosening the two nuts that secure the motor to the
belt guard and slide the guard forward. Do not over
tighten the belt. Doing so will shorten the life of the machine bearings. Tighten the two nuts.
Abrasive Belt Changing
1. Disconnect the grinder from the power source.
2. Rotate the cam handle (A) from front to back to
cause the plunger to push down on the belt tension
assembly (B). This relieves the belt tension so that
the belt can be removed.
3. Open the cover to the belt and drive wheel and
slide the belt outward off of the wheel and out of
the belt housing.
4. Install the new belt onto the drive wheel and center
the belt side to side on the wheels. This is the initial
belt tracking.
5. Release the cam handle (A) to allow the tension
assembly to raise and apply tension to the belt.
6. Turn the contact wheel by hand for one or two
revolutions of the belt to check the install and the
tracking.
7. Close and latch the cover.
8. Connect the grinder to the power supply and test the operation and verify that the belt is
tracking correctly.
9. Adjust tracking if needed.
