operation and use of the machine. The following basic safety precautions should be followed at all times to
reduce the risk of fire, electric shock and serious personal injury to you or others. Keep these important
operating instructions with this product.
WARNING!
1. Know your power tool - read owner’s/operator’s
manual carefully. Learn its applications and
limitations as well as the specific potential
hazards unique to this tool.
2. Keep guards in place - and in working order.
3. Ground all tools - if tools are equipped with
three prong plug, it should be plugged into a
three-hole electrical receptacle. If an adapter is
used to accommodate a two-prong receptacle,
the adapter lug must be attached to a known
ground. Never remove the third prong.
4. Remove wrenches - Form a habit of checking to
see that adjusting wrenches are removed from
tool before turning it “on”.
5. Keep work area clean. Cluttered areas and
benches invite accidents.
6. Do not use in dangerous environment. Do not
use power tools in damp or wet locations, or
expose them to rain. Keep work area well
lighted. Do not use tool in the presence of
flammable liquids or gasses.
7. Keep children and visitors away. All children and
visitors should be kept at a safe distance from
work area.
8. Make workshop childproof with padlocks,
master switches or by removing starter keys.
9. Do not force tool. It will do the job better and be
safer at the rate for which it was designed.
10. Use right tool. Do not force tool or attachment
to do a job for which it was not designed.
11. Wear proper apparel. Do not wear loose
clothing, gloves, neckties, rings, bracelets or
other jewelry that may get caught in moving
parts. Non-slip footwear is recommended.
Wear protective hair covering to contain long
hair.
12. Always use safety glasses. Wear safety
glasses (must comply with ANSI Z87.1) at all
times. Everyday eyeglasses only have impact
resistant lenses; they are not safety glasses.
Use face or dust mask if cutting operation is
dusty, and ear protectors (plugs or muffs)
during extended periods of operation.
13. Do not overreach. Keep proper footing and
balance at all times.
14. Maintain tools in top condition. Keep tools
sharp and clean for best and safest
performance. Follow instructions for lubricating
and changing accessories. Inspect tool cords
periodically and if damaged, have repaired by
authorized service facility.
15. Disconnect tools. When not in use, before
servicing, and when changing accessories, such
as blades, bits, cutters.
16. Avoid accidental starting. Make sure switch is in
“off” position before plugging in power cord.
17. Use recommended accessories only. Consult
the owner’s manual for recommended
accessories. The use of improper accessories
may cause risk of injury to persons.
18. Never stand on tool. Serious injury could occur
if the tool is tipped or if the cutting tool is
accidentally contacted.
19. Check Damaged Parts. Before further use of the
tool, a guard or other part that is damaged
should be carefully checked to ensure that it will
operate properly and perform it’s intended
function. Check for alignment of moving parts,
binding of moving parts, breakage of parts,
mounting, and any other conditions that may
affect it’s operation. A guard or part that is
damaged should be properly repaired or
replaced.
20. Never leave tool running unattended. Turn
power “off”. Do not leave tool until it comes to a
complete stop.
21. Extension cords. Make sure your extension
cord is in good condition. When using an
extension cord, be sure to use one heavy
enough to carry the current your product will
draw. An undersized cord will cause a drop in
line voltage resulting in loss of power and
overheating. If in doubt, use the next heavier
gage. The smaller the gage numbers the heavier
the cord.

CALIFORNIA PROPOSITION 65: Sawing and drilling generates dust. Excessive airborne
particles may cause irritation to eyes, skin and respiratory tract. To avoid breathing impairment always employ
dust controls and protection suitable to the material being saw or drilled in accordance with OSHA (29 CFR Part
1910.1). Diamond blades improperly used are dangerous. Comply with ANSI Safety Code B7.1 and OSHA covering
speed, safety guards, flanges, mounting procedures, general operating rules, handling, storage and general
machine condition.
WARNING!
8. Before use each day place 2-3 drop of pneumatic tool oil
in the air inlet of the tool. Run tool for 2-3 seconds to
allow moving parts to become lubricated. Lubricating the
tool before and during work is not needed. Excessive oil
will turn into a tar-like substance inside the tool, causing
the vanes to stick in the rotor and slow the tool down.
9. At the end of the shift disconnect air and water line and
hang the tool upside down to allow any water to drain
from the tool.
10. Clean coupler fittings on air hoses so that a motor will
not ingest powder dust and sand. Also, use clean water
from a tap.
11. If you notice deformation of a backing pad in any way,
discontinue its use and replace the backing pad.
12. Do not submerge the tool in water. This will expose the
inner moving parts to moisture that will shorten the life
expectancy.
13. Do not leave accessories attached to the threads of the
spindle. This can result in damage to the spindle or
accessory. Excessive force to the spindle trying to
remove corroded accessories could damage the gears
and bearings.
14. If you notice any abnormal noise or vibration when
operating the product, immediately discontinue its use.
Inspect and replace any damaged parts. If abnormal
noise or smell persist, return the machine for service or
repair.
15. For further operational and handling information or for
replacement of parts and components, please contact

iii. SILICA DUST WARNING
Grinding/cutting/drilling of tile, masonry, concrete, metal and other materials with silica in their composition may give off
dust or mists containing crystalline silica. Silica is a basic component of sand, quartz, brick clay, granite and numerous
other minerals and rocks. Repeated and/or substantial inhalation of airborne crystalline silica can cause serious or fatal
respiratory diseases, including silicosis. In addition, California and some other authorities have listed respirable
crystalline silica as a substance known to cause cancer. When cutting such materials, always follow respiratory
precautions.
Use appropriate NIOSH-approved respiratory protection where dust hazard may occur. Paper masks or surgical masks
without NIOSH approval number are not recommended because they do little to protect the worker. For more information
about respirator programs, including what respirators have received NIOSH approval as safe and effective, please visit the
NIOSH website at http://www.cdc.gov/niosh/topics/respirators
Observe OSHA regulations for respirator use (29 C.F.R.§1910.134).

6. Regularly clean the tool’s air vents.
7. Connect the tool to the air supply as shown
below.
viii. ABOUT AIR PRESSURE AND VOLUME
1. The manufacturer specification on the tool is
10,000 RPM at 80-90 PSI. Pressure over 90
PSI exceeds the max speed rating for the rotor
bearings that could potentially cause them to
overheat and lock.
2. The air consumption of this grinder is very
important. This tool requires 15 CFM (cubic
feet per minute) for the tool to run at a constant
speed. Each additional tool that is attached to
an air compressor will require 15 CFM.
ix. ABOUT SILENCE
To comply with OSHA code 1926.52 Noise exposure Standard, this grinder comes fitted with and
internal silencer. When operated within factory specifications (80-90 PSI @ 16 CFM) the silencer
bring the noise to less than 84 db. The silencer also provides back pressure to help assure that you are
getting a constant RPM level.
