Installation/Operating instructions for the model 20 disc grinder
The model 20 disc grinder is a three horse power heavy duty disc grinder intended for de-burring, shaping,
beveling, metals, plastics, woods, and other materials using a 20 inch PSA abrasive disc that rotates at up to
1750 RPM. Various models are available that include fixed disc speed, fixed disc speed with disc brake, and
electronic variable speed with integrated disc braking.
Models with disc brakes are recommended. The heavy rotating disc and connected motor armature
will rotate for several minutes after power is removed. Should an unsuspecting person touch the
rotating disc serious injury may occur. Do not use this machine if it does not include a disc brake and
your operating needs are such that personnel could be exposed to this hazard.
Prior to operating the model 20 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.
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 all guards are in place and functional.
8. 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.
9. 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. Note that models with variable speed control supplied by Burr King
include the foregoing safety features without the addition of a magnetic starter.
10. Insure that the model 20 AC power source is properly sized, and properly fused. In general, the three
horse power motor that is standard will draw 8 or 4 amperes with a 220v or 440v three phase supply. You
should consult a competent electrician for the correct electrical feed arrangements, or you may call Burr King
Manufacturing for guidance.
Functional operating instructions for the model 20 belt grinder
The model 20 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. Securely bolt the machine to the floor. Note that the pedestal base has four holes that are sufficient for ½
inch anchor bolts. Do not use anchor bolts that are less than 3/8 inch in diameter and/or that do not
provide for at least 2 ½ inches of depth grip in secure concrete.
