The bond of a cutting wheel holds the abrasive grains in
place, and the wheel is reinforced with fiberglass for
added strength and support.
Blotters are compressible washers that must be placed
between the wheel and mounting flange to evenly
distribute the clamping pressure on the wheel. Blotters,
when they are provided with the cutting wheels, should
be used as they help to prevent wheel breakages. Only
use blotters that are supplied or recommended by the
abrasive wheel manufacturer.
Installing & Removing
Cut-Off Wheels
Figure 5: Installing & Removing Cut-Off Wheels
1 - Remove the battery from the tool.
2 - Lay the tool on a firm surface with the opening of the
guard facing up.
3 - Engage spindle lock by depressing on the spindle lock
button to keep the spindle from spinning.
4 - Using the supplied 1/8" Allen wrench, remove spindle
screw, outer flange, and used cutting wheel, if one is
installed.
5 - Inspect the cut-off wheel for damage and replace if
necessary. Place the wheel onto the spindle, making
sure the wheel goes over the pilot diameter of the inner
flange.
6 - Place the outer flange on the spindle with the recessed
side toward the wheel.
7 - Thread the spindle screw onto the spindle and, while
engaging the spindle lock, tighten the screw securely
with the 1/8" Allen wrench.
8 - Turn the wheel by hand to ensure it is properly mounted
and not hitting the guard.
9 - Re-insert the battery and run the tool at no-load for at
least 1 minute to ensure the wheel is centered and
tightened before putting into use.

Workpiece Support
When using the cut-off tool, it is paramount to secure
and support the workpiece properly. This is essential for
the safety of the operator, accuracy and quality of the
cut. Some methods of securing the workpiece include
clamping in a vise or chuck, fixturing it to a jig or
supporting devices to prevent vibration or deflection in
long, thin workpieces.
Operation
Read, understand and
follow Safety Information
in the front of this manual.
Before each use, inspect tool and cutting wheel for damage.
1. Remove flange and screw from spindle.
2. Select a flat, reinforced resin 3" Type 1 cutting wheel to
be used with the tool.
3. Install the new wheel onto the spindle. Make sure the
wheel is flush against the face of the spindle and the
hole in the wheel fits over the boss on the spindle.
4. Engage the spindle lock and secure the wheel to the
spindle with the screw and flange. Make sure the
wheel is securely attached to the spindle.
5. This tool is started by depressing the throttle lever
tilting the safety lock to the forward direction, and
returns to the OFF position when released.
6. Allow newly mounted wheels to run free at least one
minute before using.
7. The tool is intended to cut with the edge of the wheel.
Apply the tool to the work with light pressure, allowing
the wheel to cut. Keep the wheel square with the cut,
and do not apply side loads.
8. During tool operation, it is normal for the tool to
become warm. This does not indicate a defect.
9. Always wear recommended protection and keep the
work area clean when operating the tool.
Storage and Handling of Accessories
Abrasive cut-off wheels are fragile and are easily
chipped, cracked or broken; therefore, they should be
handled with care to avoid dropping or bumping. Place
wheels and blotters flat on shelf or rack or in bins, boxes
or drawers away from excessive heat, moisture, and
other liquids to prevent warpage. Improperly stored
wheels can become damaged and lead to breakages that
can result in injuries.
