Universal Tool a Division of Florida-Pneumatic Manufacturing Corporation
851 Jupiter Park Lane, Jupiter FL 33458
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 cut-off tool
□This cut-off tool 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 cut-off wheel
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.
□Loosen the collet nut with the spanner wrenches enclosed.
□Insert the cut-off wheel into the collet.
3 Removing the cut-off wheel
WARNING: Disconnect the tool from the air supply before
servicing or changing accessories.
□Loosen the collet nut with the spanner wrenches.
□Pull the cut-off wheel out and tighten the collet nut with the
spanner wrenches.
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
[rotective respirator is recommended.
□Connect the cut-off tool 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.

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.
