turned off, unplugged from the power supply, and has come to a complete stop. Do
not engage the spindle lock while the tool is operating because damage to the tool
will result.

Mounting and Using Depressed Center Grinding Wheels
and Sanding Flap Discs
MOUNTING AND REMOVING HUBBED WHEELS
WARNING: To reduce the risk of serious personal injury, turn tool off and
disconnect tool from power source before making any adjustments or removing/
installing attachments or accessories.
Hubbed wheels install directly on the 14m2 threaded spindle. Thread of accessory
must match thread of spindle.
1. Backing flange is retained to the grinder by an o-ring on the spindle. Remove
backing flange by pulling and twisting flange away form the machine.
2. Thread the wheel on the spindle by hand.
3. Depress the spindle lock button and use a wrench to tighten the hub of the
wheel.
4. Reverse the above procedure to remove the wheel.
CAUTION: Failure to properly seat the wheel before turning the tool on may result
in damage to the tool or the wheel.
MOUNTING NON-HUBBED WHEELS
WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect tool from power
source before making any adjustments or removing/
installing attachments or accessories.
Depressed center Type 27 grinding wheels must be
used with included flanges.
1. Install the unthreaded backing flange (G) on spindle (N)
with the raised section (pilot) against the wheel. Be
sure the backing flange recess is seated onto the
flats of the spindle by pushing and twisting the flange
before placing wheel.
2. Place wheel against the backing flange, centering the wheel on the raised
section (pilot) of the backing flange.
3. While depressing the spindle lock button, thread
the clamp nut (H) on spindle. If the wheel you are
installing is more than 3.31 mm (1/8") thick, place
the threaded clamp nut on the spindle so that the
raised section (pilot) fits into the center of the
wheel. If the wheel you are installing is 3.31 mm
(1/8") thick or less, place the threaded clamp nut
on the spindle so that the raised section (pilot) is
not against the wheel.
4. While depressing the spindle lock button, tighten the
clamp nut with a wrench.
5. To remove the wheel, depress the spindle lock button and loosen the threaded
clamp nut with a wrench.
NOTE: If the wheel spins after the clamp nut is tightened,
check the orientation of the threaded clamp nut. If a thin
wheel is installed with the pilot on the clamp nut against
the wheel, it will spin because the height of the pilot
prevents the clamp nut from holding the wheel.
SURFACE GRINDING WITH GRINDING WHEELS
1. Allow the tool to reach full speed before touching
the tool to the work surface.
G
2. Apply minimum pressure to the work surface,
allowing the tool to operate at high speed. Grinding
rate is greatest when the tool operates at high speed.
N
3. Maintain a 20˚ to 30˚ angle between the tool
and work surface.
4. Continuously move the tool in a forward and
back motion to avoid creating gouges in the work
surface.
5. Remove the tool from work surface before turning
tool off. Allow the tool to stop rotating before laying it down.
