NOTE: To reduce unexpected tool movement, do not switch the
tool on or off while under load conditions. Allow the grinder to run
up to full speed before touching the work surface. Lift the tool from
the surface before turning the tool off. Allow the tool to stop rotating
before putting it down.

CAUTION: Before connecting the tool to a power source depress
and release the paddle switch (G) to ensure that the switch is off.
Depress and release the paddle switch as described above after any
interruption in power supply to the tool, such as the activation of a
ground fault interrupter, throwing of a circuit breaker, accidental
unplugging, or power failure.
To turn the tool on, push the lock-off lever (I) toward the back of the
tool, then depress the paddle switch (G). The tool will run while the
switch is depressed. Turn the tool off by releasing the paddle switch.
WARNING: Do not disable the lock-off lever. If the lock-off lever is
disabled, the tool may start unexpectedly when it is laid down.
LOCK-ON BUTTON (FIG. 6)
The lock-on button (H) offers increased comfort in extended use
applications. To lock the tool on, push the
lock-off lever (I) toward the back of the
tool then depress the paddle switch (G).
With the tool running, depress the
lock-on button (H). The tool will continue
to run after the paddle switch is released.
To unlock the tool, depress and release
the paddle switch. This will cause the tool

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 (FIG. 7)
The spindle lock button (A) is provided to
prevent the spindle from rotating when
installing or removing wheels. Operate the
spindle lock only when the tool is turned off,
unplugged from the power supply, and has
come to a complete stop. Do not engage the
spindle lock button while the tool is operating
because damage to the tool will result. To engage the lock, depress
the spindle lock button and rotate the spindle until you are unable to
