Operating instructions for the Model 760 belt grinder
The model 760 belt grinder is a three wheel path belt grinder that uses either a 1 1/2 x 60 inch or a 2 x 60
inch continuous loop abrasive belt. When fit with a model 1400, 1401, 1402, 1411 or 1412 internal grinding
attachment (optional) the belt width ranges from 1/2 to 2 inches (depending on the internal grinding
attachment model in use), and the belt length changes to 72 inches. For maximum effectiveness, and operator
safety use abrasive belts manufactured by well respected abrasive manufacturers.
* Use abrasive belts that are the proper size and type for your machine.
* Do not use abrasive belts that are old or excessively worn.
* Do not use abrasive belts that use lap splice joints. Lap spliced belts are prone to separation. They
may also tend to snag your work and create a potential safety hazard by snagging and propelling the
work part in the operator’s direction.
Prior to operating the model 760 please take time to do the following:
1. Insure that you have received all of the items that you ordered. Compare the packing slip with your
purchase order, and of course with the physical items received.
2. Verify that there is no obvious shipping damage. If shipping damage is discovered notify the freight carrier
of your intention to file a freight damage claim. They will assist you.
3. Verify that the AC power that is identified on the machine as received matches the AC power that you
intend to operate the machine with. Do not modify the machine’s wiring without first contacting your
distributor and/or Burr King Manufacturing.
4. Do not modify or defeat any AC wiring safety feature. In example, do not remove the grounding pin on the
AC plug.
5. Verify that you have received a warranty card, parts lists, catalog, and Operator, and Operating Area
Safety Instructions.
6. Complete the warranty card and return it to Burr King Manufacturing.
7. Verify that the various guards for the machine are in place and functional. See the parts list for the
indicated part numbers.
a. The contact wheel guard and backup platen are mounted and adjusted such that the platen lightly
touches the back of the abrasive belt (P/N 703, 704A, 704B).
b. The full safety guard is in place, closed and its door latch is functional such that it will securely
hold the safety door closed (P/N 742A. 742B, 742D, and 742C).
c. If an internal grinding attachment is installed insure that all pinch guards are adjusted so as to
guard the belt wheel entry points. This means that the pinch guards need to very close, but not touching the
abrasive belt (P/N 1429, 2 places, see the internal grinding attachment parts list).
8. Prior to operating the model 760 carefully read the Operator, and Operating Area Safety Instructions.
Insure that all persons who will operate the model 760, or who will work in the vicinity of the model 760
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 safe 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 760 AC power source is properly sized, and properly fused. You should consult a
competent electrician, or you may call Burr King Manufacturing for guidance.
