IMPORTANT SAFETY
INSTRUCTIONS
INSTRUCTIONS PERTAINING
TO A RISK OF FIRE,
ELECTRIC SHOCK, OR
INJURY TO PERSONS
WARNING – When using tools, basic pre-
cautions should always be followed,
including the following:
General
a. To reduce the risks of electric
shock, re, and injury to persons,
read all the instructions before us-
ing the tool.
Work area
a. Keep the work area clean and well
lighted. Cluttered benches and dark
areas increase the risks of electric
shock, re, and injury to persons.
b. Do not operate the tool in explo-
sive atmospheres, such as in the
presence of ammable liquids,
gases, or dust. The tool is able to
create sparks resulting in the ignition
of the dust or fumes.
c. Keep bystanders, children, and
visitors away while operating the

SKU 66886 For technical questions, please call 1-800-444-3353. Page 3
tool. Distractions are able to result in
the loss of control of the tool.
Personal safety
a. Stay alert. Watch what you are do-
ing and use common sense when
operating the tool. Do not use the
tool while tired or under the inu-
ence of drugs, alcohol, or medica-
tion. A moment of inattention while
operating the tool increases the risk
of injury to persons.
b. Dress properly. Do not wear loose
clothing or jewelry. Contain long
hair. Keep hair, clothing, and
gloves away from moving parts.
Loose clothes, jewelry, or long hair
increases the risk of injury to persons
as a result of being caught in moving
parts.
c. Avoid unintentional starting. Be
sure the switch is off before con-
necting to the air supply. Do not
carry the tool with your nger on the
switch or connect the tool to the air
supply with the switch on.
d. Remove adjusting keys and
wrenches before turning the tool
on. A wrench or a key that is left
attached to a rotating part of the tool
increases the risk of personal injury.
e. Do not overreach. Keep proper
footing and balance at all times.
Proper footing and balance enables
better control of the tool in unexpect-
ed situations.
f. Use safety equipment. A
dust mask, non-skid safety
shoes and a hard hat must
be used for the applicable
conditions. Wear heavy-duty work
gloves during use.
g. Always wear eye protec-
tion. Wear ANSI-ap-
proved safety goggles.
h. Always wear hearing
protection when using
the tool. Prolonged expo-
sure to high intensity noise
is able to cause hearing loss.
Tool use and care
a. Use clamps or another practical
way to secure and support the
workpiece to a stable platform.
Holding the work by hand or against
the body is unstable and is able to
lead to loss of control.
b. Do not force the tool. Use the
correct tool for the application. The
correct tool will do the job better and
safer at the rate for which the tool is
designed.
c. Do not use the tool if the switch
does not turn the tool on or off.
Any tool that cannot be controlled
with the switch is dangerous and
must be repaired.
d. Disconnect the tool from the air
source before making any adjust-
ments, changing accessories, or
storing the tool. Such preventive
safety measures reduce the risk of
starting the tool unintentionally. Turn
off and detach the air supply, safely
discharge any residual air pressure,
and release the throttle and/or turn
the switch to its off position before
leaving the work area.

SKU 66886 For technical questions, please call 1-800-444-3353. Page 4
e. Store the tool when it is idle out of
reach of children and other un-
trained persons. A tool is dangerous
in the hands of untrained users.
f. Maintain the tool with care. Keep a
cutting tool sharp and clean. A prop-
erly maintained tool, with sharp cut-
ting edges reduces the risk of binding
and is easier to control.
g. Check for misalignment or bind-
ing of moving parts, breakage of
parts, and any other condition that
affects the tool’s operation. If dam-
aged, have the tool serviced before
using. Many accidents are caused
by poorly maintained tools. There is a
risk of bursting if the tool is damaged.
h. Use only accessories that are
identied by the manufacturer for
the specic tool model. Use of an
accessory not intended for use with
the specic tool model, increases the
risk of injury to persons.
Service
a. Tool service must be performed
only by qualied repair personnel.
b. When servicing a tool, use only
identical replacement parts. Use
only authorized parts.
c. Use only the lubricants supplied
with the tool or specied by the
manufacturer.
Air source
a. Never connect to an air
source that is capable of
exceeding 90 PSI. Over
pressurizing the tool may
cause bursting, abnormal operation,
breakage of the tool or serious injury
to persons. Use only clean, dry,
regulated compressed air at the rated
pressure or within the rated pressure
range as marked on the tool. Always
verify prior to using the tool that the
air source has been adjusted to the
rated air pressure or within the rated
air-pressure range.
b. Never use oxygen, carbon dioxide,
combustible gases or any bottled
gas as an air source for the tool.
Such gases are capable of explosion
and serious injury to persons.

cussed in this manual cannot cover
all possible conditions and situations
that may occur. It must be under-
stood by the operator that common
sense and caution are factors which
cannot be built into this product, but
must be supplied by the operator.
2. WARNING: Some dust created by
power sanding, sawing, grinding, drill-
ing, and other construction activities,
contains chemicals known [to the
State of California] to cause cancer,
birth defects or other reproductive
harm. Some examples of these
chemicals are:
• Lead from lead-based paints
• Crystalline silica from bricks and
cement or other masonry products
• Arsenic and chromium from chemi-
cally treated lumber
Your risk from these exposures var-
ies, 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
those dust masks that are specially
designed to lter out microscopic
particles. (California Health & Safety
Code § 25249.5, et seq.)
WARNING: The brass components
of this product contain lead, a chemi-
cal known to the State of California
to cause birth defects (or other repro-
ductive harm). (California Health &
Safety code § 25249.5, et seq.)
3. Only use with accessories rated to
handle the forces exerted by this tool
during operation. Other accessories
not designed for the forces gener-
ated may break and forcefully launch
pieces.
4. Attach all accessories properly to the
tool before connecting the air sup-
ply. A loose accessory may detach or
break during operation.
5. Obey the manual for the air compres-
sor used to power this tool.
6. Install an in-line shutoff valve to allow
immediate control over the air supply
in an emergency, even if a hose is
ruptured.
7. Use this tool with both hands only.
Using tools with only one hand can
result in loss of control.
8. Do not lay the tool down until it has
come to a complete stop. Moving

Vibration Precautions
This tool vibrates during use. Re-
peated or long-term exposure to vibra-
tion may cause temporary or permanent
physical injury, particularly to the hands,

SKU 66886 For technical questions, please call 1-800-444-3353. Page 6
arms and shoulders. To reduce the risk of
vibration-related injury:
1. Anyone using vibrating tools regu-
larly or for an extended period should
rst be examined by a doctor and
then have regular medical check-
ups to ensure medical problems are
not being caused or worsened from
use. Pregnant women or people
who have impaired blood circulation
to the hand, past hand injuries, ner-
vous system disorders, diabetes, or
Raynaud’s Disease should not use
this tool. If you feel any symptoms
related to vibration (such as tingling,
numbness, and white or blue ngers),
seek medical advice as soon as pos-
sible.
2. Do not smoke during use. Nico-
tine reduces the blood supply to the
hands and ngers, increasing the risk
of vibration-related injury.
3. Wear suitable gloves to reduce the
vibration effects on the user.
4. Use tools with the lowest vibration
when there is a choice.
5. Include vibration-free periods each
day of work.

1. Incorporate a lter, regulator with
pressure gauge, oiler, in-line shutoff
valve, and quick coupler for best ser-
vice, as shown in the diagram above.
An in-line shutoff ball valve is an
important safety device because it
controls the air supply even if the
air hose is ruptured. The shutoff
valve should be a ball valve be-
cause it can be closed quickly.
Note: If an automatic oiler system is not
used, add a few drops of Pneumatic
Tool Oil to the airline connection be-
fore operation. Add a few more drops
after each hour of continual use.
2. Attach an air hose to the compres-
sor’s air outlet. Connect the air hose
to the air inlet of the tool. Other com-
ponents, such as a connector and
quick coupler, will make operation
more efcient, but are not required.
WARNING! TO PREVENT SERIOUS
INJURY FROM ACCIDENTAL
OPERATION:
Do not install a female quick
coupler on the tool. Such a coupler
contains an air valve that will allow
the air tool to retain pressure and
operate accidentally after the air
supply is disconnected.
Note: Air ow, and therefore tool perfor-
mance, can be hindered by under-
sized air supply components.
3. The air hose must be long enough
to reach the work area with enough
extra length to allow free movement
while working.
4. Turn the tool’s throttle or switch to the
off position; refer to Operation section
for description of controls.
5. Close the in-line safety valve be-
tween the compressor and the tool.
6. Turn on air compressor according to
manufacturer’s directions and allow it
to build up pressure until it cycles off.
7. Adjust the air compressor’s output
regulator so that the air output is
enough to properly power the tool,
but the output will not exceed the
tool’s maximum air pressure at any
time. Adjust the pressure gradually,
while checking the air output gauge
to set the right pressure range.
8. Inspect the air connections for leaks.
Repair any leaks found.

SKU 66886 For technical questions, please call 1-800-444-3353. Page 8
9. If the tool will not be used at this
time, turn off and detach the air sup-
ply, safely discharge any residual air
pressure, and release the throttle
and/or turn the switch to its off posi-
tion to prevent accidental operation.
Note: Residual air pressure should not be
present after the tool is disconnected
from the air supply. However, it is a
good safety measure to attempt to
discharge the tool in a safe fashion
after disconnecting to ensure that the
tool is disconnected and unpowered.
