Air Supply:
Tools of this class operate on a wide range of air
pres sures. It is recommended that air pressure of
these tools mea s ures 90 PSI at the tool while
running free. Low pressure (under 90 psig; 6.2 bar)
re d uc e s the speed of all air tools. Low air pressure
not only wastes time, but also costs money. Higher
pres s ure (over 90 psig; 6.2 bar) raises performance
beyond the rated capacity of the tool, which will
short e n tool life be c ause 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
rec om mend ed hookup pro ce dure can be viewed in the
above figure.
The air inlet used for con nect ing air supply, has
stan dard 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 quality air tool oil.
If no air line oiler is used, run a 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 nec tion to the air
supply, then run the tool. Overfilling will cause a
re d uc t ion in the power of the tool.
Operating Instruction:
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.
