Setup and Assembly
Any missing parts or damage should be reported
immediately to your JET
®
distributor. Do not use a
damaged tool. Read this instruction manual
thoroughly for operation, maintenance and safety
instructions.
Box contents:
1 Angle grinder
1 Pin wrench
1 Dead handle
1 Operation and parts manual
1 Warranty card
Operation
The angle grinder must be
properly lubricated before operation. See
“Lubrication” section.
Figure 1
1. Install dead handle (A, Figure 1) into
threaded hole on either left or right side of
grinder.
2. Press spindle lock (B) while rotating outer
flange (C), until you feel spindle lock engage.
Continue pressing spindle lock.
3. Place pin wrench (D) into holes of outer
flange. Rotate counterclockwise to loosen
flange, and remove it.
4. Install grinding wheel. Reinstall and tighten
outer flange, using pin wrench (clockwise)
and spindle lock.
5. Remove protective cap from air inlet (Figure
2). If an in-line oiler is not being used, add 4
or 5 drops of air tool oil (not included) into the
air inlet.
Figure 2
6. Blow out air line to remove any dirt or
moisture, then connect air supply hose to
tool. Set air pressure to 90 psi.
IMPORTANT: Connecting a quick-change
coupling directly to the tool 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.
7. Hold grinder with a light but secure grip. Slide
throttle lock out of the way while pressing
throttle lever. Pressure against throttle lever
determines speed of rotation.
8. Position grinding wheel against workpiece
with a steady pressure. Wheel rotation is
clockwise when viewed from above the tool.
9. Release throttle lever to stop grinder.
10. To reposition disc guard, push tab (E, Figure
1) toward housing, rotate guard to desired
position, then release tab. Continue rotating
guard until it “clicks” into position.
Maintenance
Lubrication
The 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 1 to 2 hours. This can be done with an in-
line oiler, or manually. If done manually, proceed
as follows:
1. Disconnect air hose from tool.
2. Place 4 or 5 drops of air tool oil into air inlet.
