Unpacking
The box should include
1 Air Die Grinder
and
2
Wrenches
. Any missing or damaged parts
should be reported to your JET
®
distributor.
Read this instruction manual thoroughly for
operation, maintenance and safety instructions.
Operation
1. The die grinder must be properly lubricated
before operating. See “Maintenance”
section for lubricating instructions.
2. 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 die grinder 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.
3. Loosen the collet nut using the two
wrenches on the flats of the collet nut and
spindle (Figure 1). Keep the wrench on the
spindle stationary while turning the wrench
on the collet nut.
4. Install a grinding point (not included) into the
collet and re-tighten the collet nut securely
using the wrenches.
5. Press forward on the safety lever and down
on the trigger (Figure 2). How far down the
trigger is pressed determines rotation speed
of the tool.
Maintenance
The die grinder 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 3 to 4 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 die grinder.
2. Place four or five drops of air tool oil* into
the air inlet (Figure 3).
[*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 may be used as
a substitute. Do not use detergent oil.]
3. Re-connect the air. Run the die grinder
without load for a few seconds to distribute
the oil throughout the tool.
