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
Important Warnings - Grinders & Cut-Off Tools
1. The stopping time, if longer than 5 seconds, shall be stated, and it shall be recommended to put the grinder in a stable position.
2. When cutting-off, the workpiece shall be so supported that the slot is kept at constant or increasing width during the whole operation.
3. If the abrasive product gets jammed in a cut slot, shut off the grinder and ease the wheel free. Check that the wheel is still correctly
secured and not damaged before continuing the operation.
4. Grinding wheels and cut-off wheels shall not be used for side grinding. (Exception: grinding wheels designed for side grinding.) Grinders
should not be used over the maximum rated speed of an abrasive product.
5. The operator shall pay attention that no bystanders are in the vicinity.
6. The personal protective equipment such as gloves, apron and helmet shall be used.
7.
8.
9. Only use grinding wheels and cut-of wheels and wire brushes that meet ANSI standards, ISO standards or both-this will be shown on the
wheel manufacturers label.
10. Only use grinding wheels and cut-off wheels and wire brushes that have the correct center mounting hole or correct threaded insert
center to match the spindle thread on the grinder.
11. Never adjust the grinder, adjust the guard or change the wheel unless the air supply and air hose is disconnected from the grinder.
12. Only personnel trained in the correct methods to adjust guards and change grinding wheels or cut-off wheels or wire brushes should
conduct these operations.
13. 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 to the operator or other persons in the area.
14.
15.
16. Never attempt to modify or adapt a grinder or cut-off tool to accept a grinding wheel or cut-off wheel or wire brush that the grinder was
not designed for use with.
17. Eye protection, hearing protection, safety gloves and safety aprons must always we worn when operating a grinder

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 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 grinder
□This 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.
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.
□Loosen the collet nut with the wrench.
□Insert the grinding stone in the collet.
□Tighten the collet nut with the wrench.
□Loosen the collet nut with the wrench.
□Remove the grinding stone from the collet.
□Tighten the collet nut with the wrench.

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.
