Operation
CHECKING THE GRINDER
The model 760 was fully tested and veri ed to
comply with requirements prior to shipping from the
factory. You should perform the following steps:
1. Adjust the work support and work support arm to
the desired position with the Attachment Locking
Lever (Figure 7). Take care that the gap between
the face of the abrasive belt and the work rest
is at most 1/8 inch. WARNING: Be aware that
thin section work pieces can pass through this
gap if the gap is not properly adjusted. Ejected
work parts can cause serious personal injury!
2. With the machine securely bolted to its table, pedestal,
and/or oor point connect the AC power to its source.

WARNING:
FIRST DISCONNECT THE MACHINE FROM
ITS AC POWER SOURCE. A COMPETENT
ELECTRICIAN SHOULD PERFORM ALL
ELECTRICAL WORK ON THE MODEL 760.
3. Engage the motor by placing the ON/OFF switch
to ON. The belt should rotate smoothly in a
counterclockwise direction around the machine wheel
belt path. If either of these conditions is not met
immediately turn the machine OFF.

the contact wheel while the belt is moving use the
Tracking Adjustment Knob (Figure 8) on the upper
left side of the machine to track the belt. Turn this
control clockwise to cause the belt to track to the
left; conversely, turn the control counterclockwise
to cause the belt to move to the right.
