8. Prior to operating the model 562 read the Operator, and Operating Area Safety Instructions
carefully. Insure that all persons who will operate the model 562, or who will work in the
vicinity of the model 562 read, understand, and comply with these instructions.
9. Insure that the grinder is located in an area that provides clear access to the machine such
that operators have clear and unobstructed access to the machine. The work place should be
free from floor obstructions, trip points, and other faults that may reduce operator safety.
10. Burr King recommends that all three phase installations include a magnetic starter.
Magnetic starters protect motors from “single phasing”, overheating, etc. thereby reducing
the risk of damage to the equipment and/or fire hazard to your facility.
11. Insure that the model 562 AC power source is properly sized, and properly fused. You
should consult a competent electrician, or you may call Burr King Manufacturing for
guidance.
Functional operating instructions for the model 562 belt grinder
The model 562 was fully tested and verified to comply with requirements prior to shipping
from the factory. No adjustments should be necessary. You should perform the following
steps:
1. With the machine securely bolted to its table, pedestal, and/or floor point connect the AC
power to its source.
2. Adjust the work support and work support arm (P/N 706, 405) to the desired position.
Take care that the gap between the face of the abrasive belt and the work rest is at most
1/8 inch.
3. Insure that the abrasive belt is tensioned properly. To do this raise the tensioning handle
(P/N 537G). You will hear mechanical clicks as the tensioning ratchet pawl (737F) moves.
Generally, the belt will be adequately tensioned when you hear three to eight clicks. To
reduce or release the belt tension slightly raise the tensioning handle (P/N 437A) then press
the button (P/N 737B) in the center of the tensioning handle. Move the tensioning handle
down slightly to reduce belt tension or all the way down to release belt tension.
4. Engage the motor by placing the ON/OFF switch to ON. The belt should rotate smoothly
in a CCW direction about the machine wheel belt path. If either of these conditions are not
met turn the machine OFF immediately.
a. If the abrasive belt does not remain centered on the contact wheel (P/N 502) while
the belt is moving use the tracking adjustment (P/N 711) on the upper left side of the
machine to track the belt. Turning this control CW to cause the belt to track to the left,
conversely turn the control CCW to cause the belt to move to the right.
b. If the belt runs in reverse ( up from the floor) you may correct this by changing the
main drive motor rotation direction. FIRST DISCONNECT THE MACHINE FROM ITS
AC POWER SOURCE. A COMPETENT ELECTRICIAN SHOULD PERFORM ALL
ELECTRICAL WORK ON THE MODEL 562.
1) Reversed 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.
c. If the machine belt tensions, and tracks properly, but has excessive vibration turn
the machine OFF and call the Burr King factory for assistance.
