CAUTION:
Allow the tool to reach full
speed before touching tool to the work
surface. Lift the tool from the work
surface before turning the tool off.
SPINDLE LOCK
The spindle lock pin is provided to prevent the
spindle from rotating when installing or removing
wheels. Operate the spindle lock pin only when the
tool is turned off, the battery is removed, and the
wheel has come to a complete stop.
NOTICE:
To reduce the risk of damage
to the tool, do not engage the spindle
lock while the tool is operating. Damage
to the tool will result and attached
accessory may spin off possibly
resulting in injury.
To engage the lock, depress the spindle lock button
and rotate the spindle until you are unable to rotate
the spindle further.

MOUNTING AND REMOVING HUBBED WHEELS (FIG. 6)
WARNING:
To reduce the risk of
serious personal injury, turn tool off and
remove battery pack before making
any adjustments or removing/installing
attachments or accessories.
Hubbed wheels install directly on the M14 threaded
spindle.
1. Thread the wheel on the spindle by hand.
2. Depress the spindle lock button and use a
wrench to tighten the hub of the wheel.
3. 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 (FIG. 1, 6, 7)
WARNING:
To reduce the risk of
serious personal injury, turn tool off and
remove battery pack before making
any adjustments or removing/installing
attachments or accessories.
Depressed centre Type 27 grinding wheels must be
used with included flanges.
1. Install the anti-lockup backing flange (f) on
spindle (r) with the raised centre (k) 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 the
wheel(s).
2. Place wheel against the backing flange, centring
the wheel on the raised centre of the backing
flange.
3. While depressing the spindle lock button, thread
the clamp nut (g) on spindle. If the wheel you
are installing is more than 3.17 mm (1/8") thick,
place the threaded clamp nut on the spindle so
that the raised centre fits into the centre of the
wheel (Fig. 7A). If the wheel you are installing is
3.17 mm (1/8") thick or less, place the threaded
clamp nut on the spindle so that the raised
centre is not against the wheel (Fig. 7B).
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.
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.
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.
