4. To install or remove an abrasive disc remove the 3/8 bolts that are located just under the table and on
either side of the table. Tilt the table away from the disc. Install the PSA disc taking care to position it
concentric to the aluminum backing disc.
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.
5. As before assure that the disc spins freely.
6. Reposition the table, reinstall the 3/8 bolts.
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 right hand table support. Note: Use of a precision protractor is recommended
where angles of plus/minus 2 degrees are required.
4. Disc rotation can be selected using the provided control if so equipped. This control may be a simple
selector switch, or an electric control module depending on how your model 12 is equipped.
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.
Maintenance for the model 12
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.
2. Keep the dust channel under the disc and any connected dust conduits free from dust build up.
3. Use spark arrest devices to minimize the risk of fire or explosion.
Remember for optimum operator safety and the continued
effectiveness of your model 12:
Read and understand these instructions and the included “Operator
and Operating Area Safety” instructions.
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.
Never grind material that is less than ¼ inch thick in its smallest dimension without the use of work
piece holding devices to protect the operator and/or bystanders. Failure to use a holding device 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.
Do not operate the model 12 until you are fully trained to do so safely.
Do not defeat the safety guards and other safety provisions of the model 12.
Do not operate the model 12 with safety guards removed, or counter to these instructions.
