OPERATOR, and OPERATING AREA SAFETY
Subject equipment includes Grinders, buffers, polishers, and other rotating equipment. Serious injury
or death may occur if minimum safety precautions are not understood, and obeyed by operators and
those other persons who may be in the immediate vicinity of the subject equipment. Persons who
operate, or are in the immediate vicinity of the subject equipment must be properly trained in, and
use, minimum safety precautions and procedures for such machinery.
Minimum safety requirements to operate, or work in the immediate vicinity subject equipment:
1. Read and understand all operating instructions, manuals, labels, and other information provided with the
equipment.
2. Install the equipment according to manufacturer’s instructions.
3. Securely bolt the equipment to a rigid, structurally sound mounting surface.
4. Use and wear proper eye and face protection.
5. Use and wear proper protection for the body, hands, fingers, feet, and legs.
6. Review and understand all machine guards, adjustments, and points of exposure to potential injury.
7. Do not remove, tamper with, or otherwise alter, equipment guards, and other safety features.
8. Insure the machine is adjusted, and remains adjusted according to manufacture’s requirements.
9. Maintain the equipment in good operating condition.
10. Have another person who is knowledgeable in proper and safe operation of the subject equipment
demonstrate proper and safe operation to all operators, and to those persons who might be in the immediate
vicinity of the subject equipment.
11. Use work piece holding devices when ever possible that diminish the possibility that persons will come
in contact with moving machine pieces, or spark/debris output from the machine.
12. Use spark and debris arresting apparatus. Such apparatus should be connected to the machine so as to
contain dust and debris that is generated, and to suppress sparks thereby limiting human inhalation risk, and
the risk of fire or explosion.
13. Use appropriate inhalation apparatus to protect person from ingestion and/or inhalation of sparks, debris,
smoke, particulates, etc.
14. Avoid mixing different metals, alloys, and materials. To mix such materials might create a fire or
explosion hazard.
15. Protect persons from work pieces, particulates, etc. that could be forcibly ejected from the machine. For
example, a buffing wheel or grinding belt can “grab” a work piece while the work piece is being buffed,
polished, ground, or otherwise conditioned, resulting in forcible ejection toward the operator or those in the
vicinity of the machine. The use of leather aprons, gloves, and eye shields are examples of protective gear
that may be effective. In general do not grind, buff, or otherwise engage the traveling belt, wheel, or disc
surface with the work piece pointing into the direction from which the belt, wheel, or disc is traveling.
However, if you choose to do so be aware the work piece may lodge in the traveling belt, wheel, or disc and
be forcibly, and dangerously ejected.
16. Do not operate this machine if the gap (nip point) between a moving belt, wheel or disc and the work
support surface exceeds 1/8 inch.
17. Do not operate this machine if the gap between the moving abrasive belt, disc or wheel and the adjacent
face
page 1 continued on next page

Continued from page 1
of the work rest (or table) will permit passage of the work piece through the gap (nip point). Note, however,
that certain alloys such as titanium may create conditions where grinding debris can accumulate in a tight gap
creating a potential fire hazard. When in doubt consult with your safety officer. Failure to observe this
warning may result in the work piece or other item being caught in this gap, and/or being forcibly ejected.
Failure to heed this warning may cause serious bodily harm to the operator and/or bystanders. NEVER USE
THIS EQUIPMENT IF YOU ARE NOT PROPERLY TRAINED IN ITS OPERATION and/or SAFE
USE! IF IN DOUBT STOP and ASK FOR GUIDANCE!
18. Never position the work rest table at an acute angle between the top of the work rest table and the moving
belt or wheel. Doing so will create “nip point” that can cause serious injury should an operator body part
become entangled (pulled into) the nip point created by this acute angle.
19. Do not operate the equipment, or allow others to operate the equipment without proper training in these
and other rotating machinery safety requirements.
20. Do not perform maintenance on the equipment unless you are fully qualified to do so, and understand all
necessary safety and operating requirements.
21. Do not leave the machine unattended while it is running.
22. Correct equipment or safety problems immediately. Do not operate the equipment when it requires
maintenance, or correction.
23. Install and use high quality abrasive belts, wheels, discs, media, etc., as appropriate to your machine.
Understand and follow the operating requirements provided by the manufacturer of these materials.

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.
See our catalog at www.burrking.com Contact us at [email protected] 1

See our catalog at www.burrking.com Contact us at [email protected] 2
2. Verify that the disc spins freely. Note that on models with motor brakes the disc will be locked. At the
rear of the motor you will find a control that when rotated will free the brake to rotate. This control
should be left in the locked position for normal operation of the machine.
3. Verify that the gap (nip point) between the PSA abrasive disc and the table edge next to the front of the
disc is less than 1/8 inch. This gap is set at the factory to comply with this requirement. The gap should
not change unless table erosion occurs, maintenance to the machine is attempted, or damage has
occurred.
4. To install or remove an abrasive disc push the disc guard to its rear most position. Install the PSA disc
taking care to position it concentric to the aluminum backing disc.
Note: To remove or replace a PSA disc it is necessary to lower the disc grinder table clear of the aluminum
backing disc. To do this first unlock the table by loosing the table clamp at the rear of the machine. Lower or
raise the table by rotating the large hand wheel to the right of the table.
Note: PSA abrasive discs can leave a residue on the aluminum backing disc. Normally this can be cleaned
with isopropyl alcohol and a soft rag.
Note: Do not spin or otherwise force the table mechanism to the end of travel up or down. To do so
may shear keepers, shafts, or gears inside the table gear box. Always secure the table with the table
locking clamp before using the model 20 grinder.
5. As before assure that the disc spins freely.
6. Loose the table locking knob to the left of the table. Using the small hand wheel to the right of the table
verify that the table can be angled in respect to the disc. Always re-lock the table.
Grinding modes
1. The direction of disc rotation determines the point of grinding.
Never grind on the side of the disc where the movement of the abrasive disc is upward from the table.
Doing so may create an operator hazard from debris, and or ejected work pieces.
2. Supported work: Always use work piece holding devices to minimize the risk of operator contact with
the rotating abrasive disc.
3. For controlled angle grinding tilt the table down to any angle from 0 to 45 degrees. Read the angle on the
indicator found on the small hand wheel. Note: Use of a precision protractor is recommended where
angles of plus/minus 2 degrees are required.
4. Use the available miter attachment for grinding compound or other angles.
5. Use reduced disc speed (variable speed models) for many materials where abrasive speed is critical. The
abrasive speed at the outer disc perimeter is approximately 9000 SFPM at 1750 RPM.
Note: Never grind with the table tilted in an acute angle (up) in respect to the disc while holding the
work piece by hand. The disc may seize the part stall the machine, and or injure the operator. This
operating mode should only be used where the work part is firmly secured to the table as in bolting,
clamping, etc. and the operator is well protected from potential injury.
Note: Never position work pieces at an acute up angle with disc with the table at any angle.
Doing so may lead to serious operator or bystander injury.
Note: Never grind material that is less than ¼ inch thick in its smallest dimension with out the use of
work piece holding devices that protect the operator and bystanders. Doing so may lead to serious
operator or bystander injury.
Beware that thin (less than ¼ inch) material can lodge in the gap between the table and the disc
creating a potential for serious injury, and/or property damage.
Maintenance for the model 20
ALWAYS DISCONNECT THE MACHINE FROM ITS AC POWER SOURCE PRIOR TO
CHANGING THE PSA DISC OR PERFORMING MACHINE MAINTENANCE.
1. Vacuum or otherwise remove dust and debris build-up from the machine.

See our catalog at www.burrking.com Contact us at [email protected] 3
2. Lightly grease the gears inside the table rotator and table gear box every 6 months or when ever
movement seems restricted.
3. Apply a light coat of thin machine oil to the central column every 30 days.
4. Keep the dust channel under the disc and any connected dust conduits free from dust build up.
5. Use spark arrest devices to minimize the risk of fire or explosion.
6.
Remember for operator safety and the continued effectiveness of your
model 20:
Read and understand these instructions and the included “Operator
and Operating Area Safety” instructions.
Do not operate the model 20 until you are fully trained to do so safely.
Do not defeat the safety guards and other safety provisions of the model 20.
Do not operate the model 20 with safety guards removed, or counter to these instructions.
Do not reach inside the safety guards while the machine is running.
Do not use fluids in your grinding process unless your model 20 is designed for liquid operation
(NEMA 4, 4X). To do so may create an electrical safety hazard. Only specially ordered model 20
grinders are “liquid safe”.
Do not use your model 20 to grind/polish explosive materials unless it is equipped with explosion proof
electrical devices and motor.
Do not mix alloys in your grinding. To do so may create an explosion/fire hazard.
Do not modify the model 20 other than securing holding devices to the work table.
Do use eye, hand, face, arm, leg, feet and body protection that is adequate to protect against flying
debris, forcibly ejected work pieces, etc. Note: Consult with your safety officer in regard to your
facilities policy regarding attire such as gloves when using rotating equipment.
Do train operators and others in safe operating practices.
Post these or equivalent instructions such that they are available for
ready operator reference.
