and to a stable base below the guard. The brace should be capable of supporting
75 pounds and be safely out of the operator’s way.
3. A wheel running in reverse rotation can unscrew from the spindle, creating a serious
personnel safety hazard. Always check for proper wheel rotation prior to
mounting wheels on the Model 1200 (see item 4 below) Insure that the Model 1200
spindle operates CCW when viewed from the right side of the machine. Note that the
left spindle has a left-hand thread that assures the left buffing wheel will not spin off
of the machine during correct rotation of the spindle. The right spindle has a right-
hand thread. After determining correct rotation mount the wheels with proper bushing
and flanges, then tighten securely.
4. Your model 1200 has been shipped to you with 2 cap plugs on each end of the spindle
it is very important that once you have selected the wheel you will be using on your
machine that you cut the plug to the size of the exposed thread. Failure to do so may
expose the operator to risk of injury should clothing or loose objects become snagged
on the exposed area.
4. Engage the motor by placing the ON/OFF switch to ON. The wheel should rotate
smoothly in a CCW direction with the front face of the buffing wheel moving toward the
floor. If either of these conditions are not met turn the machine OFF immediately.
If the Model 1200 runs in reverse direction you must correct this by changing the main
drive motor rotation. FIRST DISCONNECT THE MACHINE FROM ITS AC
POWER SOURCE. A COMPETENT ELECTRICIAN SHOULD PERFORM ALL
ELECTRICAL WORK ON THE MODEL 1200.
All single phase Model 1200 buffers are set up for correct rotation at the factory.
The phasing of your “in-house” electric service will effect three phase Model 1200
rotation.
1) Reverse the motor direction of a fixed speed three-phase motor by
reversing any two legs of the input power lines.
2) Reverse the motor direction of a fixed speed 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.
3) Reverse the direction of a variable speed motor by following the
instructions supplied with the motor.
If your Model 1200 is equipped with variable speed control the wheel speed can be
adjusted using the speed control that will be mounted on the motor or on a separate
control box.
If your Model 1200 is fixed speed, or variable speed turn the machine ON or OFF using
the controls provided, or by using the controls that are provided in your or by Burr King
magnetic starters, etc.
