Wheels

WARNING: To minimize the risk of eye injury, always
use eye protection. Carbide is a hard but brittle
material. Foreign objects in the workpiece such as wire
or nails can cause tips to crack or break. Mount the
wheel securely in proper direction of rotation before
using, and always use a clean, sharp wheel.

WARNING: To reduce the risk of injury, only use wheels
that are no greater than 3" (76 mm) in diameter,
have an inner diameter of 3/8" without cutting teeth.
Thickness of wheel not to exceed 0.09" (2.2 mm). Never
force a wheel onto the machine or alter the size of the
arbor hole.
A dull wheel will cause slow inefficient cutting, overload the
motor, could cause excessive splintering, and could increase
the possibility of kickback. Please refer to the table below to
determine the correct wheel for your application.

WARNING: Burn Hazard. Sharp parts. ALWAYS wear
gloves when changing wheels. Wheels have sharp
edges or may get extremely hot during operation, and
may damage bare hands.

1. Remove the battery.
2. Lay unit on a firm surface, with the spindle
facing upward.
3. Hold spindle lock button
from turning. Spindle threads are left hand.
4. Using supplied 6 mm wrench
screw 19 , outer flange
is installed and inner flange
left hand.
5. Slip the inner flange over the spindle.
6. Slip wheel over spindle. Make sure wheel goes over pilot
diameter of inner flange.
NoTE: When installing diamond*** wheels, always
match direction of rotation of the wheel to the desired
direction of rotation of the tool. Diamond*** wheels

will not cut effectively unless the direction marked on
the wheel matches the direction of rotation. Check the
setting of the forward/reverse/lock off button
sure it matches the direction marked on the wheel.
7. Slip on outer flange with the flat side towards the
cut‑off wheel.
NoTE: The text "LOOSE TIGHTEN" will be visible when
installed correctly.
8. Start threading on spindle screw which will self align
outer flange. Make sure the wheel is fitted in the
correct orientation.
9. Engage spindle lock button and tighten spindle screw
with wrench. Do not over tighten spindle screw.
10. Turn wheel by hand to ensure it is properly centered. The
wheel should not hit the shoe, guard or spindle screw.
The spindle screw and flanges should be tight.
Adjusting the Guard Angle (Fig. E)

WARNING: Remove battery first. To reduce the risk of
injury when grinding, ALWAYS adjust the guard to
provide the best control and protection. ALWAYS wear
gloves to protect your hands when adjusting the guard.
You can adjust the angle of the guard.
1. Remove the battery.
2. Grasp the guard firmly and rotate to desired angle.

The guard can rotate 30 degrees, forward or backward.
Mounting, Removing and Adjusting the
Dust Shroud (Fig. F)
NoTE: The dust shroud is only for tile/concrete and drywall
cutting applications to connect to a vacuum for dust
collecting. We do not recommend use of the shroud for
metal cutting applications.
1. Remove the battery.
2. With the wheel properly installed, rotate the guard
all the way forward.
3. Loosen the depth of cut wing nut
the shoe. Hand‑tighten the depth of cut knob.
4. Maneuver the upper guard and wheel into the dust
shroud assembly 9 and rotate tool to lock in place.
The front of the guard will rest against the stop inside
the assembly, and the back of the guard will catch the
release tab 21 .
To Remove the Dust Shroud
1. Remove the battery.
2. Loosen the depth of cut wing nut and fully extend the
shoe. Hand‑tighten the depth of cut wing nut.
3. Press in the shroud release button
out of the dust shroud assembly.
To Adjust the Depth of Cut
1. Loosen the depth of cut wing nut and slide the shroud
up or down. Use the markings on the depth of cut gauge
to help determine proper depth. Adjust the cutting
depth to the thickness of the workpiece. Less than 1/4" of
the wheel should be visible below the workpiece.
