General

a. To reduce the risks of electric

shock, re, and injury to persons,

read all the instructions before
using 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

explosive 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
tool. Distractions are able to result in

the loss of control of the tool.

Personal safety

a. Stay alert. Watch what you are

doing and use common sense
when operating the tool. Do not
use the tool while tired or under

the inuence of drugs, alcohol, or

b. Dress properly. Do not wear loose

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 trigger is released 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 trigger pressed.

d. Do not overreach. Keep proper

footing and balance at all times.

Proper footing and balance
enables better control of the tool in
unexpected situations.

e. 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.

f. Always wear eye

protection. Wear ANSI-

approved safety goggles

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 trigger

does not turn the tool on or off.
Any tool that cannot be controlled
with the trigger is dangerous and
must not be used until repaired.

precautionary measures reduce the
risk of injury to persons.

e. Store the tool when it is idle out

of reach of children and other

untrained persons. A tool is
dangerous in the hands of untrained
users.

f. Maintain the tool with care. A

properly maintained tool reduces
the risk of binding and is easier to
control.

g. Check for misalignment or binding

of moving parts, breakage of
parts, and any other condition
that affects the tool’s operation.

If damaged, 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

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

chemically treated lumber
Your risk from these exposures
varies, 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

permanent physical injury, particularly to
the hands, arms and shoulders. To reduce
the risk of vibration-related injury:

1. Anyone using vibrating tools regularly

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,

nervous 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

possible.

SAVE THESE

INSTRUCTIONS.

2. Do not smoke during use. Nicotine

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 between

different processes.

2. Attach an air hose to the
compressor’s air outlet. Connect the
air hose to the air inlet of the tool.
Other components, such as a coupler
plug 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

performance, can be hindered by
undersized 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.

1. Incorporate a lter, regulator with
pressure gauge, oiler, in-line shutoff
valve, and quick coupler for best
service, 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 because it can be closed
quickly.

Note: If an automatic oiler system is not

used, add a few drops of Pneumatic
Tool Oil into the airline connection
before operation. Add a few more

4. Release the tool’s trigger.

5. Close the in-line safety valve between
the compressor and the tool.

6. Turn on the air compressor according
to the 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.

Page 9For technical questions, please call 1-800-444-3353.SKU 92917

8. The air pressure setting must
not exceed job site regulations/
restrictions. The air pressure setting
must not exceed 90 PSI when being
used with work pieces that have a
thickness of less than 1-3/4”.

9. Inspect the air connections for leaks.
Repair any leaks found.

10. If the tool will not be used at this time,
turn off and detach the air supply,
safely discharge any residual air
pressure, and release the trigger 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.

the regular checks and maintenance
explained as part of the regular
operation of the air-operated tool.

1. Daily - Air Supply Maintenance:

Every day, perform maintenance
on the air supply according to
the component manufacturers’
instructions. The lubricator’s oil
level needs to be maintained and

the moisture lter must be regularly

drained. Performing routine
maintenance on the air supply will
allow the tool to operate more safely
and will also reduce wear on the tool.

TO PREVENT SERIOUS
INJURY FROM TOOL
FAILURE:
Do not use damaged
equipment. If abnormal noise,
vibration, or leaking air is
detected, have the problem
corrected before further use.

TO PREVENT EXPLOSION:

Lubricate only with specied

lubricants. Lubricate the air
inlet using only pneumatic
tool oil.
