On the back end of the polisher, there is a dial for speed adjustment. Refer
to the speed chart below for settings.
Don’t operate the tool at low speeds under a heavy load for
extended periods of time. This may cause the motor to overheat,
posing damage to your tool.

this tool.

Don’t exert force on the polisher. The weight of the polisher is enough
to supply adequate amount of pressure to get the best results. Let the
pad and polisher do their work. Exerting extra force will put strain on
the motor, wear off the polishing pad quickly, and reduce the
polishing speed. Additional strain on the motor can cause overheating,
thus damaging the polisher.
n
Never polish a specific area for long periods, otherwise 50 and 100 grit
polishing pads will remove more material than you intend to, making
the surface uneven.
n
Don’t apply extra force as it may overheat the motor, causing damage
to the tool.
n
If the motor heats up, switch off the polisher and wait until the motor
comes to a complete halt. Then remove it from the work piece. Take
your hand away from the venting duct, remove the polishing disc and
switch it back on and run the polisher free without any load until the
motor cools down.
Selecting the right polishing pad with correct grit for the task at hand plays
an important role in achieving high quality finish. DiamaPro Systems® has
developed polishing pads for the HGP-5 model bonded to achieve
excellent results when polishing concrete or stone.
Generally, when using diamond polishing pads, coarse grit removes the
most material and fine grits produce the best finish. The condition of the
surface to be polished determines which grit will do the best job. If the sur
-
face is rough, start with a coarse grit and grind until the surface is uniform.
Then use medium grit to remove scratches left by the coarser grit.
At last, use finer grits for finishing the surface. Always continue polishing
with each grit until the surface is uniform.

Owner’s Manual
Some dust produced by power polishing, sawing, grinding, drilling, and
other construction activities contains chemicals known (to the State of Cal
-
ifornia) to cause cancer, birth defects, or other reproductive harm. Some
examples of these chemicals are:
•
Lead, from lead based paints
•
Crystalline silica, from bricks and cement and other masonry products
•
Arsenic and chromium, from chemically treated lumber
Your risk from these exposures varies depending on how often you do
this type of work. To reduce your exposure to these chemicals, work in a
well-ventilated area and work with approved safety equipment, such as
dust masks that are specifically designed to filter out microscopic particles.
