tool. Distractions are able to result in
the loss of control of the tool.
Personal safety
Stay alert. Watch what you are do-a.
ing and use common sense when
operating the tool. Do not use the
tool while tired or under the inuence of drugs, alcohol, or medication. A moment of inattention while
operating the tool increases the risk
of injury to persons.
Dress properly. Do not wear loose b.
clothing or jewelry. Contain long
hair. Keep hair, clothing and gloves
away from moving parts. Loose
clothes, jewelry, or long hair increases risk of injury to persons as a result
of being caught in moving parts.
Avoid unintentional starting. Be c.
sure the switch is off before connecting to the air supply. Do not
carry the tool with your nger on the
Trigger or connect the tool to the air
supply with the switch on.

sure to high intensity noise
is able to cause hearing loss.
Tool use and care
Use clamps or another practical a.
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.
Do not force the tool. b. Use correct
tool for application. The correct tool
will do the job better and safer at the
rate for which the tool is designed.
Do not use the tool if the switch c.
does not turn the tool on or off.
Any tool that cannot be controlled
with the switch is dangerous and
must be repaired.
Disconnect the tool from the air d.
source before making any adjustments, 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.
Store the tool when it is idle out of e.
reach of children and other untrained persons. A tool is dangerous
in the hands of untrained users.
Maintain the tool with care. f. Keep
tool sharp and clean. A properly
maintained tool reduces the risk of
binding and is easier to control.

Check for misalignment or bind-g.
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.
Use only accessories that are h.
identied by the manufacturer for
the specic tool model. Use of an
accessory not intended for use with
the specic tool model, increases the
risk of injury to persons.
Never use oxygen, carbon dioxide, b.
combustible gases or any bottled
gas as an air source for the tool.

TO PREVENT
EXPLOSION:
Use only clean, dry, regulated,
compressed air to power this
tool. Do not use oxygen,
carbon dioxide, combustible
gases, or any other bottled
gas as a power source for this
tool.
1. Incorporate an in-line oiler, shut-off
valve, regulator with pressure gauge,
and lter for best service, as shown in
the diagram above. An in-line 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 continual use.
Attach an air hose to the compres-2.
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 efcient, 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 undersized air supply components.
The air hose must be long enough 3.
to reach the work area with enough
extra length to allow free movement
while working.
If the tool will not be used at this 9.
time, 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 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.
Make sure the tool’s throttle or switch 4.
is in the off position; refer to Operation section for description of controls.
Close the in-line safety valve be-5.
tween the compressor and the tool.
Turn on the air compressor according 6.
to the manufacturer’s directions and
allow it to build up pressure until it
cycles off.
Adjust the air compressor’s output 7.
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.
Inspect the air connections for leaks. 8.
Repair any leaks found.
