OPERATING INSTRUCTIONS
Read the ENTIRE IMPORTANT
SAFETY INFORMATION
section at the beginning of this
manual including all text under
subheadings therein before set
up or use of this product.
Inspect tool before use, looking

repaired.
Tool Set Up
TO PREVENT
SERIOUS INJURY
FROM ACCIDENTAL
OPERATION:
Turn off the tool, detach the
air supply, safely discharge
any residual air pressure in
the tool, and release the
throttle and/or turn the switch
to its off position before
performing any inspection,
maintenance, or cleaning
procedures.
TO PREVENT SERIOUS
INJURY:
Do not adjust or tamper with
any control or component in a
way not specifically explained
within this manual. Improper
adjustment can result in
tool failure or other serious
hazards.
1. To install a bit (with 1/8” shank),
loosen the Clamping Nut (22), slide
the bit’s shank through the Clamping
Nut and through the 1/8” Collet (21).
2. Tighten finger tight, then use the two
Collet Nut Wrenches, one on the top
of the Clamping Nut, and the other on
the Collet Holder (18) and tighten the
tip securely.
Work Piece and Work Area Set Up
1. Designate a work area that is clean
and well-lit. The work area must not
allow access by children or pets to
prevent injury and distraction.
2. Route the air hose along a safe route
to reach the work area without creat-
ing a tripping hazard or exposing the
air hose to possible damage. The air
hose must be long enough to reach
the work area with enough extra
length to allow free movement while
working.
3. Secure loose workpieces using a vise
or clamps (not included) to prevent
movement while working.
4. There must not be hazardous ob-
jects (such as utility lines or foreign
objects) nearby that will present a
hazard while working.
General Operating Instructions
1. If an automatic oiler is not used, add
a few drops of Pneumatic Tool Oil to
the air-line connection before use.
Add a few more drops after each
hour of continual use.
2. Have the desired bit installed in the
end of the grinder and secured.
3. Wear ANSI-approved safety glasses.
4. Ensure that the Control Ring (3) is
in the “OFF” position. Plug the Male
Coupler Plug to an air compressor.
