LUBRICATION
An automatic inline filter-regulator-lubricator is recommended as it increases tool life and keeps the tool in sustained op-
eration. The inline lubricator should be regularly checked and filled with air tool oil. Proper adjustment of the inline lubrica-
tor is performed by placing a sheet of paper next to the exhaust ports and holding the throttle open for approximately 30
seconds. The lubricator is properly set when a light stain of oil collects on the paper. Excessive amounts of oil should be
avoided.
In the event that it becomes necessary to store the tool for an extended period of time (overnight, weekend, etc.), it should
receive a generous amount of lubrication at that time. The tool should be run for approximately 30 seconds to ensure oil
has been evenly distributed throughout the tool. The tool should be stored in a clean and dry environment.
• It is most important that the tool be properly lubricated by keeping the inline lubricator filled and correctly
adjusted.
Without proper lubrication the tool will not work properly and parts will wear prematurely.
• Use the proper lubricant in the inline lubricator.
The lubricator should be of low air now or changing air now
type and should be kept filled to the correct level. Use only recommended lubricants, specially made for pneu-
matic applications. Substitutes may harm the rubber compounds in the tool's O-rings and other rubber parts.
USER-MAINTENANCE INSTRUCTIONS
If a filter/regulator/lubricator is not installed on the air system,
air operated tools should be lubricated at least once a day or after
2 hours work with 2 to 6 drops of oil, depending on the work envi-
ronment, directly through the male fitting in the tool housing. Only
a qualified technician should perform procedures not specifically
explained in this manual.
1. Incorporate an in-line oiler, shut-off valve, regulator
with pressure gauge, and filter for best service, as
shown in the diagram at right.
An inline shutoff valve
is an important safety device because it controls the air
supply even if the air hose is ruptured.
Note:
If an automatic oiler system is not used, add a few
drops of pneumatic tool oil to the airline connection
before operation. Add a few more drops after each hour
of continuous use.
2. Attach an air hose to the compressor's air outlet.
Connect the air hose to the air inlet of the tool.
INSTALLATION
1. Attach a standard 1/4" air connector to the tool's air inlet.
Wrap the threaded portion of the air connector
with Teflon tape. Tighten securely.
2. Attach a standard quick-connector to the air pressure source hose.
Attach the air hose to the tool.
3. Set the air pressure regulator on the air compressor to 90 PSI.
Do not exceed the recommended pressure of 90 PSI. Excess pressure could result in damage to
the tool, to your work piece or serious injury.
4. Check the air line and its connections for air leaks.
Do not use this tool until you have repaired all air leaks.
Note:
Turn off the air compressor, disconnect the air pressure hose and discharge any residual pressure before
changing accessories or making any adjustments to the tool. Failure to do so could result in severe injury or
property damage.

DESCRIPTION
The 1/4" Air Die Grinder is ideal for light duty metal fabrication, grinding, porting and polishing applications. Durable,
lightweight composite housing design helps reduce vibration. Lever lock throttle for safety.
OPERATION
1. Connect the tool to the air hose.
2. Release the safety lock and depress the trigger to operate the tool.
3. Allow the tool to reach full speed before applying grinder bit to the work piece.
4. Ensure the air supply is clean and does not exceed 90 PSI while operating the tool.
Higher air pressure
and dirty air will shorten the tool's life due to excessive wear, and could result in damage to the work piece and
serious personal injury.
DO NOT use any additional force upon the grinder in order to work faster.
DO NOT allow tool to run without a load for an extended period of time as this will shorten
its life.
MAINTENANCE
Disconnect tool from air supply before changing accessories, servicing or performing mainte-
nance. Replace or repair damaged parts immediately.
1. Lubricate the tool daily by dropping a few drops of air tool oil into the air inlet, or use an in-line oiler as
described on Page 4.
2. Clean the tool after use.
