Unpacking
Any missing parts or damage should be reported
immediately to your JET
®
distributor. Read this
instruction manual thoroughly for operation,
maintenance and safety instructions.
Operation
1. The drill must be properly lubricated before
operating. See “Maintenance” section for
lubricating instructions.
2. Install a bit (not provided) into the chuck,
and rotate the chuck by hand until firmly
tight. Make sure the bit is centered in the
chuck.
3. Remove the protective cap from the air inlet,
and connect the air supply hose. Make sure
the air pressure is set to 90psi.
IMPORTANT:
Connecting a quick-change
coupling directly to the Air Drill is not
recommended, as vibration may cause the
connection to fail. Instead, add a leader
hose and install any quick-change couplings
farther down the line.
Maintenance
The drill should be lubricated daily (or before
each use) with air tool oil through the air inlet.
During continual operation, it should be re-oiled
every 1 to 2 hours. This can be done either with
an in-line oiler, or manually. If done manually,
proceed as follows:
1. Disconnect the air hose from the drill.
2. Place 4 or 5 drops of air tool oil* into the air
inlet (Figure 1).
[*NOTE: Air tool oil not provided. It may be
purchased from your JET dealer, or is
available at most major hardware and tool
stores. SAE #10 weight oil or sewing
machine oil may be used as a substitute. Do
not use detergent oil.]
3. Re-connect the air. Run the drill without load
for a few seconds to distribute the oil
throughout the tool.

4. When you are finished operating the air drill,
before storing it disconnect the air hose and
place 4 or 5 drops of air tool oil into the air
inlet; re-connect the air and run the tool for a
few seconds to distribute the oil.
5. Avoid storing the drill in very humid locations
which promotes rusting of internal
mechanisms, and always oil it before
storage.
Air Connection
1. Make sure that the air compressor supplies
clean air at the correct CFM for the drill.
2. Set air pressure to 90 psi.
Excess air pressure and/or
unclean air will shorten the tool’s life and
may create a hazardous situation.
3. Drain the water from the air compressor tank
daily, as well as any condensation from the
air lines. Water in the air line may enter the
tool and cause damage.
4. Change filters on the air system on a regular
basis.
5. Air line pressure should be increased
accordingly to compensate for extra long air
hoses (usually over 25 feet). Inside diameter
of the hose should be a minimum of 3/8”.
