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

for damaged, loose, and

missing parts. If any problems

are found, do not use tool until

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 specically 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 nger 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.
