Safety Information (continued)
AIR COMPRESSOR AND AIR TOOL SAFETY
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:
1. Risk of Bursting. Do not adjust the regulator to result in output
pressure greater than the marked maximum pressure of this air
tool.
Lead from lead based paint, crystalline silica from bricks
and cement and other masonry products, arsenic and
chromium from chemically-treated lumber.
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.
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 specifically designed to filter out microscopic particles.
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.
Important Warnings - Die Grinders
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 flammable 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.

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 fittings with pipe thread
tape if leaks are found.

□□ 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 &frac12;&quot; or larger
depending on the total length of the hose.
□□ Do not use a multiple number of hoses
connected together with a quick connect
fitting. This causes additional pressure drops
and reduces the tool power. Directly connect
the hoses together.
There is moisture blowing out
of the tool’s exhaust.
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 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.

Frequently Answers and Questions

How do I install the grinding stone?

Loosen the collet nut with the spanner wrenches. 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 spanner wrenches.

What is the recommended operating pressure for the die grinder?

The recommended operating pressure for the die grinder is 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.

How do I lubricate the die grinder?

An in-line filter-regulator-lubricator is recommended as it increases tool life and keeps the tool in sustained operation. Regularly check and fill 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.

What should I do if the tool runs slowly or will not operate?

Flush the tool with air tool oil or gum solvent. Lubricate the tool according to the lubrication instructions in this manual. Adjust the regulator on the tool to the maximum setting. Adjust the compressor regulator to the tool’s maximum setting of 90 psi. Tighten and seal the hose fittings with pipe thread tape if leaks are found. 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 fitting. This causes additional pressure drops and reduces the tool power. Directly connect the hoses together.
