⚠ WARNING
⚠ 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.
⚠ WARNING
FAILURE TO OBSERVE THESE WARNINGS COULD RESULT IN 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
accessories to do the work.
NOTE: During operation, safety goggles should always be worn to guard against
flying debris (users and bystanders).
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 the water from air lines and compressor
prior to running tool. Clean the air inlet filter screen weekly. The
recommended hook-up procedure can be viewed in FIG. 1.
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.
Ensure an accessible emergency shut off valve has been installed in the air
supply line and make others aware of its location.
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.
LUBRICATION AND MAINTENANCE
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.
