CHECK ITEMS BEFORE OPERATING
･ READ THE AIR PRESSURE ON THE GUAGE
Hold air pressure as specified before use. Operating the polisher at air pressure
more than the specified value could cause damage of the polisher and the flexible
polishing pad and, in the worst case, injuries to operator.
･ DO NOT USE POWER SOURCES OTHER THAN COMPRESSED AIR
Use of high-pressure gas ( e.g. oxygen, acetylene gas, propane gas etc. ) could
result in dangerous explosion. Do not use air other than compressed by air
compressor.
WARNING
･ DO NOT USE THE POLISHER FOR APPLICATIONS OTHER THAN SPECIFIED IN
THIS INSTRUCTION MANUAL
This polisher is exclusively for polishing stone materials. Do not apply it for
grinding and polishing of metal, wood, etc.
･ CARRY OUT VISUAL INSPECTION BEFORE OPERATING
Ensure each screw is not loose and the part are located as designated. In
addition, make sure that the wrenches and / or screwdriver is not left on the
polisher.
CAUTION
Ensure the following items before operating.
1. KEEP-IN-ORDER OF WORKPLACE
Keep the workplace in order before the start of polishing operation. When there is dust
around, it would be flown by the exhaust air conducted through the exhaust air duct
hose ( see Figure 3 and 6, page 6 and 11 ). Flying dust would cause respiratory
diseases at throat and lungs.
2. COMPRESSOR CAPACITY
Select and install a compressor with sufficient capacity margin for air consumption. Use
of the compressed air containing water and dust could cause rusting and other troubles.
Before operating, therefore, drain out water completely through the drain port provided at
the bottom of the compressor tank.
3. OPERATING AIR COMPRESSED PRESSURE
This polisher is designed for operation at the maximum air pressure of 0.6MPa. Since
the higher air pressure leads the higher rotational speed, do not apply the exceeded air
pressure against specified to prevent the bursting of the flexible polishing pad and / or
the rubber pad, which may cause injuries, and the short life of the motor of the polisher.

Adjust airflow rate by turning the airflow control valve in the range MIN position to
MAX position shown in Figure 9. Turning it over MAX position to STOP position
reduces the airflow rate due to valve structure.
3. HOW TO POLISH A WORK PIECE WITH THE FLEXIBLE POLISHING PAD
When the polisher rotation gets stable after the start, begin the polishing operation, Put
the flexible polishing pad slowly on the face to be polished when it comes in touch with
a work piece. Too much force to the pad would damage the work piece and cause
quick worn-out of the pad, and would not be an efficient polishing.
The efficient polishing depends on many elements, characteristics of work piece, the
flexible polishing pad, pressure between the flexible polishing pad and work piece, water
flow rate, skill of operator and polisher speed.
The operator would have an experience of optimum water flow rate. Contact of polisher
speed is utilized by airflow control value ( see Figure 1, page 6 ) The optimum polishing
speed, therefore, could not be specified in this instruction manual due to too many
elements.
Relation of r/min and compressed air pressure is shown in Figure 5 in page 8. The
operator would have an experience of optimum polisher speed.
4. CAUTIONS IMMEDIATELY AFTER USE
After the polishing operation, turn OFF the switch lever and place the polisher on floor
ensuring that its rotation is completely stopped. Failure to do so could cause accidents.
Inordinate impact to the polisher body could result in tear or crack of the polisher and
the flexible polishing pad. Handle them with good care.
