Safety Information (continued)
AIR COMPRESSOR AND AIR TOOL SAFETY
1. Risk of Bursting. Do not adjust the regulator to result in output
pressure greater than the marked maximum pressure of this air
tool.
2. Ensure the hose is free of obstructions or snags. Entangled or
snarled hoses can cause loss of balance or footing and may
become damaged.
3. Never leave a tool unattended with the air hose attached.
4. Do not operate this tool if it does not contain a legible warning
label.
5. Do not continue to use a tool or hose that leaks air or does not
function properly.
6. Never direct a jet of compressed air toward people or animals.
7. Protect your lungs. Wear a face or dust mask if the operation is
dusty.
WARNING: Some dust created by power sanding, sawing,
grinding, drilling and other construction activities contains
chemicals known to cause cancer, birth defects or other
reproductive harm. Some examples of these chemicals are:
Lead from lead based paint, crystalline silica from bricks
and cement and other masonry products, arsenic and
chromium from chemically-treated lumber.
Your risk from those 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 specically designed to lter out microscopic particles.
Important Warnings - Die Grinders
Specications
1. Only use mounted grinding stones or mounted carbide burrs that meet ANSI standards, ISO standards or both.
2. Never adjust the die grinder, adjust the collets or change the mounted stones or mounted burrs unless the air supply and air hose is
disconnected from the die grinder.
3. Only personnel trained in the correct methods to adjust collets and change mounted stones and mounted burrs should conduct these
operations.
4. Always ensure that you are aware of the direction of the sparks being created by the grinding operation and ensure that the sparks are
not directed toward the operator or other persons in the area.
5. Never use a die grinder close to any explosive or ammable materials or air conditioners.
6. Only use mounted stones or carbide burrs that have the correct spindle diameter that matches the original collet size provided by the die
grinder manufacturer.
7. Particular care must be taken not to use metric size mounted stones and mounted burrs with die grinders that have imperial size collets,
or use imperial mounted stones and mounted burrs with die grinders that have metric collets.

Installation
1 Cleaning the air hose
□A 3/8" air hose is required, with a maximum length of 25 ft.
□Clean the air hose of accumulated dust and moisture
before connecting it to the air supply.
NOTE: If a longer air hose is required, connect a 1/2" air
hose to the 3/8" air hose to ensure the die grinder has the
necessary air supply.
Ensure the air line is shut-off and drained of air before removing this tool for service or changing sockets. This will prevent the tool from
operating if the throttle is accidentally engaged.
LUBRICATION
□An in-line lter-regulator-lubricator is recommended as it increases tool life and keeps the tool in sustained operation.
□Regularly check and ll the in-line lubricator with air tool oil. Avoid using excessive amounts of oil.
□Adjust the in-line lubricator by placing a sheet of paper next to the tool’s exhaust ports and holding the throttle open approximately 30
seconds. The lubricator is properly set when a light stain of oil collects on the paper.
□If it is necessary to store the tool for an extended period of time (overnight, weekend, etc.), generously lubricate the tool through the air
inlet. Run the tool for approximately 30 seconds to ensure the oil is evenly distributed throughout the tool. Store the tool in a clean and
dry environment.
□Recommended lubricants: Air tool oil or any other high grade turbine oil containing moisture absorbent, rust inhibitors, metal wetting
agents, and an EP (extreme pressure) additive.

Operation
1 Operating the die grinder
□This Die Grinder is designed to operate on 90 PSIG. Lower
pressure (below 90 PSIG) will reduce performance of
the tool. Higher air pressure (over 90 PSIG) raises the
performance of the tool beyond its rated capacity and
could cause serious damage to the tool and the user.
2 Installing the grinding stone
WARNING: Disconnect the tool from the air supply before
servicing or changing accessories.
WARNING: Always use ANSI approved grinding stones
with the rated tool RPM.
3 Removing the grinding stone
WARNING: Disconnect the tool from the air supply before
servicing or changing accessories.
□Loosen the collet nut with the angle double ended spanner
wrench and the double headed spanner wrench.
□Pull the grinding stone out and tighten the collet nut with the
angle double ended spanner wrench and the double headed
spanner wrench.
4 Grinding and deburring
WARNING: You must wear the ANSI approved eye
protection during the operation; failure to follow this this may
result in serious injury or damage to the operator.
WARNING: Hearing protection is strongly recommended. A
protective respirator is recommended.
Lever
□Loosen the collet nut with the angle double ended spanner
wrench and the double headed spanner wrench.
□Insert the grinding stone in the collet. If using a 1/8 in.
collet stone, an adapter (not included) must be inserted
before placing the stone into the tool.
□Tighten the collet nut with the angle double ended spanner
wrench and the
double headed
spanner wrench.
□Connect the die grinder to the air supply.
□This tool features the safety lock-off mechanism.
□Operate the tool by disengaging the lock-off mechanism and
depressing the throttle lever to run the tool for grinding or
deburring.

Troubleshooting
Problem Possible Cause Solution
The tool runs slowly or will not
operate.
There is grit or gum in the tool. Flush the tool with air tool oil or gum solvent.
The tool is out of oil. Lubricate the tool according to the lubrication
instructions in this manual.
The air pressure is low. □Adjust the regulator on the tool to the
maximum setting.
□Adjust the compressor regulator to the tool’s
maximum setting of 90 psi.
The air hose leaks. Tighten and seal the hose ttings with pipe thread
tape if leaks are found.
The air pressure drops. □Ensure the hose is the proper size. Long
hoses or tools using large volumes of air may
require a hose with an I.D. of ½" or larger
depending on the total length of the hose.
□Do not use a multiple number of hoses
connected together with a quick connect
tting. This causes additional pressure drops
and reduces the tool power. Directly connect
the hoses together.
There is a worn rotor blade in the motor. Replace the rotor blade.
There is a worn ball bearing in the motor. Remove and inspect the bearing for rust, dirt, and
grit. Replace or clean and grease the bearing with
bearing grease.
There is moisture blowing out
of the tool’s exhaust.
There is water in the tank. Drain the tank. (See the air compressor manual
for instructions.) Lubricate the tool and run it until
water is not evident. Lubricate the tool again and
run for 1-2 seconds.
