INSTALLING ABRASIVE WHEELS
Always use the arbor nut that has same
thread size as the output shaft.
1. Install abrasive wheel onto output shaft.
2. Thread arbor nut provided onto
output shaft finger tight, depress shaft lock
and tighten wheel with the wrench provided
(Fig. 4).
Do not overtighten. Cracks
in the wheel can occur if
overtightened. Use wrench provided with
tool. Other wrenches may promote
overtightening.
Do not depress shaft lock
while the tool is running.
Depressing the shaft lock may cause wheel
to spin off or damage to attachment.

Operating Instructions
MAKING A CUT
1. Make sure material being cut is secured in
a vise or fixture before attempting to cut.
2. Keep your body positioned to either side of
the wheel, but not in line with wheel. It is
important to support the tool properly and to
position your body such as to minimize body
exposure from possible wheel binding and
recoil.
3. Grip the tool with both hands when cutting
and always be ready and able to manage the
cut.
4. Avoid jamming, twisting or pinching the
wheel with the workpiece or otherwise
applying excessive side pressure to the wheel.
5. Keep guard covering between wheel and
user.
6. Make sure the guard lock lever is in the
closed position and the guard is securely
mounted to the attachment. Use the allen
wrench to adjust the guard adjustment screw.
7. Maximum cutting depth is 11/16”.
Overtightening the guard
adjustment screw can
permanently damage the locking mechanism.
Test the tightness of the lever after each full
turn of the adjustment screw.
To prevent recoil and
damage to the tool, always
ensure that the inner or outer flanges never
contacts the workpiece surface.
8. Generally, the harder the material being
worked on, the faster the wheel will wear.
9. When cutting thicker material, never make
the cut in one pass. Make successive passes
until you reach desired depth.
10. When using the Diamond Wheel, do not
make long, continuous cuts. Allow the blade to
cool for approximately 10 seconds for each
minute cutting.
APPLICATIONS
This tool is intended for cutting the following
materials.
1/8˝ maximum thick sheet steel.
Floor and wall tile.
Concrete cinder blocks and bricks.
Reinforcing rod-generally under 5/8˝ diameter.
1/8˝ concrete wire mesh.
Electrical conduit 1/8˝ wall thickness.
1/8” maximum thick structural forms such as:
channels, angles, plate and etc.
ATTENTION: If you run the tool continuously
for more than 5 minutes, it is normal for the
housing to feel warm.
It is important to read and understand the
section in this manual called “Causes and
Operator Prevention of Recoil”.
