SPINDLE LOCK BUTTON (FIG. 2)
The spindle lock button (C) is provided to prevent the spindle from rotating when
installing or removing wheels. Operate the spindle lock button 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
button 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 (C) and rotate the spindle until
you are unable to rotate the spindle further.

MOUNTING AND REMOVING HUBBED WHEELS
WARNING: To reduce the risk of serious personal injury, turn tool off and
remove the battery pack before making any adjustments or removing/installing
attachments or accessories. An accidental start-up can cause injury.
Hubbed wheels install directly on the 5/8"-11 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.
NOTICE: 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. 9)
WARNING: To reduce the risk of serious personal
injury, turn tool off and remove the battery pack
before making any adjustments or removing/installing
attachments or accessories. An accidental start-up can
cause injury.
Depressed center Type 27 grinding wheels must be
used with included flanges. See pages 12 and 13 of this
manual for more information.
1. Install the unthreaded backing flange (G) on spindle
(D) with the raised section (pilot) against the 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 3.17 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 (Fig. 10A). 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
section (pilot) is not against the wheel (Fig. 10B).
4. While depressing the spindle lock button, tighten the clamp nut with a wrench.
