Operation
CHECKING THE GRINDER
The model 760 was fully tested and verified 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 floor point connect the AC power to its source.
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.
a. If the abrasive belt does not remain centered on
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.
b. If the belt runs in reverse (up from the floor) you must
correct this unsafe condition by changing the main drive
motor rotation direction. (See instructions below.)
c. If the abrasive belt tensions and tracks properly,
but has excessive vibration, turn the machine
off and call OREGON® for assistance.
Always unplug the machine before performing
any adjustments to the work platforms.
WARNING:
FIRST DISCONNECT THE MACHINE FROM
ITS AC POWER SOURCE. A COMPETENT
ELECTRICIAN SHOULD PERFORM ALL
ELECTRICAL WORK ON THE MODEL 760.
1. Reverse the motor direction of a three phase motor
by reversing any two legs of the input power lines.
2. Reverse the motor direction of a single phase
motor by reversing leads 5 and 8 found within
the metal wiring box located on the motor, or as
otherwise instructed on the actual motor label.
