Oregon 760 Mode D'emploi page 8

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.
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.
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.
1. Reverse the motor direction of a three phase motor
by reversing any two legs of the input power lines.
