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.

jewelry or loose clothing. Secure long hair. Scalping can occur
if hair is not kept away from tool and accessories. Choking
can occur if neckwear is not kept away from tool and
accessories.
• Do not force tool beyond its rated capacity.
• RPM of the accessory must exceed tool RPM. Use
accessories rated at 4,500 RPM or higher.

AIR SUPPLY
Tools operate on a wide range of air pressures. It is recommended
that air pressure of these tools 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 1/2" NPT.
Line pressure should be increased to compensate for unusually long
air hoses (over 25 feet). Minimum hose diameter should be 3/4" I.D.
and fittings should have the same inside dimensions and be tightly
secured.
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
connection 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.
OPERATION
Always turn off the air supply, drain hose of air pressure and detach
tool from air supply before installing, removing or adjusting any part
or accessory on this tool, or before performing any maintenance on
this tool.
Needle Scalers are used for removal of rust, old paint, concrete
and slag from new welds on many uneven metal surfaces. Needles
adapt themselves to flat, curved and uneven surfaces.
Excessive speed reduction indicates too much force being applied
to the work surface.
Apply moderate hand pressure to the tool and allow the tools acces-
sories to do the work.
NOTE: During operation, safety goggles must always be worn
to guard against flying debris (users and bystanders).
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.
