PLEASE REVIEW ALL WARNING INSTRUCTIONS PRIOR TO OPERATION. SAVE THIS MANUAL FOR FUTURE REFERENCE.
AIR SUPPLY
Tools of this class operate on a wide range
of air pressures. It is recommended that air
pressure of these tools measures 90 PSI at the
tool while running free. Low pressure (under 90
psig; 6.2 bar) reduces the speed of all air tools.
Low air pressure not only wastes time, but also
costs money. Higher pressure (over 90 psig; 6.2
bar) raises performance beyond the rated capacity
of the tool, which will shorten tool life because of
faster wear 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 air tank daily. Clean the air
inlet filter screen on at least a weekly schedule.
The recommended hookup procedure can be
viewed in the above figure.
The air inlet used for connecting air supply, has
standard 1/4" NPT American Thread. 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.
LUBRICATION
Lubricate the air motor daily with NAPA air tool
oil. If no air line oiler is used, run a teaspoon 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.
The amount of oil to be used is 1 ounce.Over-
filling will cause a reduction in the power of the
tool.
OPERATING INSTRUCTIONS
Locate center of new hole by using a center
punch. Place drill bit tip in punch mark. Hold drill
square with work and start motor. Apply steady,
even pressure. Do not force. Too much pressure
can cause bit to break or overheat. Too little
pressure will keep bit from cutting and cause it to
overheat.
Reduce pressure just before bit cuts through the
work. When bit has penetrated work and is
spinning freely, take it from the work while the
motor is running, then turn off drill. If the drill
jams in the work, release throttle immediately.
Disconnect the drill before removing bit and
determining cause of trouble. Do not attempt to
free the bit by starting and stopping the motor.
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, and tool continues erratic action or low
power, disconnect tool from hose and contact
your nearest NAPA/EVERCRAFT authorized service
center.
