! RISK OF ELECTRIC SHOCK
WHAT COULD HAPPEN
HOW TO PREVENT IT
• Using air tools to attach electrical wiring can result in
electrocution or death.
• Never use nail/staplers to attachelectrical wiring
while energized.
•This tool is not provided with an insulated gripping
surface. Contact with a "live" wire will also make
exposed metal parts of the tool "live" and can result
in electrocution or death.
• Avoid body contact with grounded surfaces such as
pipes, radiators, ranges and refrigerators. There is
an increased risk of electric shock if your body is
grounded.
• Fasteners coming in contact with hidden electrical
wiring could cause electrocution or death.
• Thoroughly investigate the workpiece forpossible
hidden wiring before performing work.
! RISK OF ENTANGLEMENT
WHAT COULD HAPPEN
HOW TO PREVENT IT
•TooIs which contain moving elements, or drive other
moving parts, such as grinding wheels, sockets, sanding
discs, etc., can become entangled in hair, clothing,
jewelry andotherloose objects, resulting in severe injury.
« Neverwear loose fitting clothes orapparelthat
contains loose straps or ties, etc., which could
become entangled inmoving parts ofthetools.
• Remove any jewelry, watches, identifications,
bracelets,necklaces, etc.,whichmightbecome
caught by the tool.
• Keep hands away from moving parts.Tie up orcover long
hair.
• Always wear proper fittingclothingandothersafety
equipment when using the tool.
! RISK OF CUT OR BURNS
WHAT COULD HAPPEN
HOW TO PREVENT IT
•TooIs that cut, shear, drill, staple, punch, chisel, etc.
are capable of causing serious injury.
• Keep theworking part of the tool away from hands
and body.
• Replace warning labels if they become obscured orremoved.
• Do not use this tool for other than its intended use.
• Excessive air pressure or too much free rotation will decrease the life of the
tool and may cause a hazardous situation.
• Check air hosefor wear,and keep themaway from heatand sharp edges. Do not
carry the tool by the air hose.
• Slip / trip/ fall isa major causeof serious injuryor even death.Be aware of
excess hose left on your walking way or on the working surface and be aware
of the whipping air hosetoo.
• Continuous operation and bad working condition will injure hands. Once hand
numbs oraches, operator shall stop the toolfora while for relaxing and re-start the
work after recovery. Operator shall immediately see a doctor if such a serious
symptom occurs.

• Keep visitors a safe distance from the work area. keep children away.
• This product may contain one or more chemicals known to cause cancer
and birth defects or other reproductive harm. Wash hands after handling.
AIR SUPPLY
Please refer to the diagram below.
1. Make surethat the aircompressor being usedfor the airtool operation supplies
the correct output (CFM).
2. Have the tool in the “off” position when connecting the tool to the air supply.
3. Use normal 90 psi (or ranging from 6.0 to 8.0 kg.) air pressure while running the tool.
High pressure and unclean air will shorten the tool’s life due to faster wear and also may
create a hazardous situation.
4. Drain water from air compressor tank daily, as well asany condensation inthe air lines.
Water in the air line may enter the tool and damage the tool mechanisms at operation.
5. Clean the air inlet filter cartridge weekly. The recommended hook-up procedure can be
viewed in the diagram below.
6. Line pressure should be increased accordingly to make up for extra-long air hoses (usually
over 8meters). The minimum hose diameter should be 1/4” I. D. and the
fittings should have the same inside dimensions. But usually a 3/8” l.D. air hose is
recommended for air supply to get the best function of air tool operation.
7. Use proper hoses and fittings. We do not suggest connecting quick change couplings
directly to the tool since they may ca use failure due to vibration. Instead, add a
leader hose and connect coupling between air supply and hose whip.
8. Check hosesfor wear before individual use. Makecertain that allconnections are in
security.

PACKAGING CONTENTS
PREPARATION
Figure 1
Before beginning assembly or operation of the product, make sure that all parts are
present. Compare the parts with the package contents list. If any part is missing or
damaged, do not attempt to assemble, install or operate the product. Contact the
distributor or sales agent for replacement.
OPERATING INSTRUCTIONS
1. Lubricate thetool before operating. See “CARE AND
MAINTENANCE” section for oilinginstructions.
2. Loosen the collet fixing cap (Part #31) counterclockwise with
one wrench while holding the other wrench on the flats of
the collet base (Part #27). (See Figure 1)
3. Insert a grinding accessory like a grinding stone (not
provided) into the collet hole. (See Figure 2)
4. Tighten the collet fixing cap clockwise with one wrench while
holding the other wrench on the flats of the collet base. Make
sure the collet fixing cap is securely tightened. (See Figure 3)
! Only use grinding accessories that have an RPM
rating equal to or greater than the tool itself.

5. Remove the air cap from the tool air inlet and connect the air
supply hose to the tool. Set the air pressure at 90 PSI.(See Figure
4)
6. Push forward the lever block (Part #4)and press down on the
lever trigger (Part #3). How far the lever trigger is pressed
determines the tool rotation speed. Then the tool starts to
work. (See Figure 5)
CARE AND MAINYENANCE
The tool shouldbe lubricated daily(or before eachuse) with air
tool oil (not included).
Air tool oil is available at major tool hardware stores. SAE
#10 weightoil or sewingmachine lubricant orany other
high grade turbine oil containing moisture absorbent,
rust inhibitors, metal wetting agents and an EP (extreme
pressure) additive may be used as a substitute. Do not
use detergent oil.
During continuous operation, the tool should be oiled
every 1 to 2 hours. This may be done using an in-line oiler,
or manually. If done manually, proceed as follows:
1. Disconnect the tool from air supply. (See Figure 6)
2. Place a few drops of air tool oil into the air inlet.
(See Figure 7)
Avoid the misuse of thicker oil which may lead to the reduced
performance or malfunction.
3. Connect thetool to theair supply. Run thetool without load for
a fewseconds to distribute the oil through the tool.
Any excess oilmay be propelledfrom the exhaustarea. So
keep the tool away in a safedirection.
4. After operating the tool and before storing the tool,
disconnect the airhose and place4 or 5drops of airtool oil into
the air inlet, then re-connect the air hose and run the tool to
evenly distribute the oil throughout the tool for 30 seconds
approximately. This will prolong thetool life.
5. Avoid storing the tool in a humid environment which
promotes rusting of internal mechanisms. Always oil the tool
before storage.
6. When thetool is seriously damaged or outof life, itshould be
left ina resource recyclingcan. Never dropit into fire.

TROUBLESHOOTING
Problem
Possible Cause
Corrective Action
Tool runs slowly
or will not
operate
1. Grit orgum in tool.
2. No oil in tool.
3. Low airpressure.
4. Air hose leaks.
5. Pressure drops.
6. Worn rotor blade.
7. Moisture blowing out
of tool exhaust.
1. Flush the tool with air-tool oil or gumsolvent.
2. Lubricate the tool according to the lubrication
instructions in this manual.
3. a. Adjust the regulator on the toolto maximum
setting.
b. Adjust the compressor regulator to tool
maximum of 90 PSIG.
4. Tighten and seal hose fittings if leaks are found. Use
sealing tape.
5. a. Besure the hose is the proper size. Long hose or
tools using large volumes of air may require ahose
with an 1. D. of 1/2in. or largerdepending on the total
length of the hoses.
b. Do not use a multiple number of hoses
connec ted together with quick-connect fittings.
This causes additional pressure drops and reduces
the tool power. Directly connect the hoses
together.
6. Replace rotor blade.
7. Water in tank: drain tank. (See air compressor
manual). Oil tool and run until no water is evident. Oil
tool again and run 1-2 seconds.
Abnormal
vibration and/or
excessive heat
develops in
the tool.
Improper lubrication.
Follow proper lubrication procedures in this manual.
For any special troubles which cannot be settled down by the operator, contact the
distributor or sales agent from whom you purchase the tool.
