WARNING
Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known 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 and other masonry
products, and
• 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 filter out microscopic particles.

AIR SUPPLY
Tools operate on a wide range of air pressures. It is recommended
that air pressure measures 90 psig at the tool with the trigger fully
depressed and no load applied to the tool. Higher pressure (over 90
psig; 6.2 bar) raises performance beyond the rated capacity of the
tool, which will shorten tool life and could cause injury.
Always use clean, dry air. Dust, corrosive fumes and/or water in the
air line will cause damage to the tool. Drain water from air lines
and compressor prior to running tool. Clean the air inlet filter screen
weekly. The recommended hookup procedure can be viewed in the
above figure.
The air inlet used for connecting air supply has standard 1/4" NPT.
Line pressure should be increased to compensate for unusually long
air hoses (over 25 feet). Minimum hose diameter should be 3/8" I.D.
and fittings should have the same inside dimensions and be tightly
secured.
Always turn off the air supply, drain hose of air pressure and detach
tool from air supply before installing, removing or adjusting any part
of accessory on this tool, or before performing any maintenance on
this tool.
Ensure an accessible emergency shut off valve has been installed in
the air supply line and make others aware of its location.
LUBRICATION
Lubricate the air motor daily with high quality air tool oil. If no air
line oiler is used, run 1/2 oz. of oil through the tool. The oil can be
squirted into the tool air inlet or into the hose at the nearest con-
nection to the air supply, then run the tool. A rust inhibitive oil is
acceptable for air tools.
WARNING: After an air tool has been lubricated, oil will discharge
through the exhaust port during the first few seconds of operation.
The exhaust port must be covered with a towel before applying air
pressure to prevent serious injury.
TROUBLESHOOTING
Other factors outside the tool may cause loss of power or erratic
action. Reduced compressor output, excessive drain on the air
line, moisture or restrictions in air pipes or the use of hose
connections of improper size or poor conditions may reduce air
supply. Grit or gum deposits in the tool may cut power and may be
corrected by cleaning the air strainer and flushing out the tool with
gum solvent oil or an equal mixture of SAE #10 and kerosene. If
outside conditions are in order, disconnect tool from hose and take
tool to your nearest authorized service center.
OPERATION
OPERATION NOTE: Always shut off air supply, drain hose of air
pressure and disconnect tool from air supply when not in use,
before changing accessories or when making repairs.
Ensure an accessible emergency shut off valve has been installed
in the air supply line and make others aware of its location.
Ensure the work piece is securely fixed.
Always place the needle tube onto the tool and hold tool down to
the work before operating. Damage to the tool may result if this
precaution is not followed.
To avoid injury, the throttle must never be depressed unless the
needles are held firmly against the work place. Do not use wire or
any other fixing to lock the throttle lever in the on/open position.
NOTE: During operation, safety goggles should
always be worn to guard against flying debris
(users and bystanders).
Make sure needle tube (#20) is tightened securely on cylinder (#14)
before operating tool.
To Change Needles:
1. Remove needle tube (#20) and slide the needle holder (#18)
out of tube.
2. Remove old needles from holder and insert new ones. The holes
in the needle holder are countersunk; make sure needles drop
inside holder so that top of needle is flush with top of holder.
Never use dull, chipped or damaged accessories. Never cool a
hot accessory in water as brittleness and early failure can result.
Accessory breakage or tool damage may result from prying. Take
smaller bites to avoid getting stuck.
NOTE: Never operate tool until inspected and confirmed
needles are properly secured in the tool.
Never operate tool until inspected and confirmed needles are
properly secured in the tool.
