OPERATION

Guards and Flanges
It is important to choose the correct guards and flanges to use with
the grinder accessories. See page 6 and this page for the correct
accessories.
NOTE: Edge grinding and cutting can be performed with Type 27
wheels designed and specified for this purpose.
WARNING: Accessories must be rated for at least the speed
recommended on the tool warning label. Wheels and other acces-
sories running over rated accessory speed may burst and cause
injury. Every unthreaded accessory must have a 7/8" arbor hole. If
it does not, it may have been designed for a circular saw and
should not be used. Use only the accessories shown on pages 6–7.
Accessory ratings must be above listed minimum wheel speed as
shown on tool nameplate.
Switches
CAUTION: Hold the side handle and body of the tool firmly to
maintain control of the tool at start up and during use and until the
O
wheel or accessory stops rotating. Make sure the wheel has come
N
to a complete stop before laying the tool down.
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.
PADDLE SWITCH (D28402, D28402N)
CAUTION: Before connecting the tool to a power source depress
and release the paddle switch (A) once [D28402: without depress-
ing the lock-on button (J)] to ensure that the switch is off. Depress
and release the paddle switch as described above after any inter-
ruption 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. If the paddle switch is locked on, the
tool will start unexpectedly when it is reconnected.
To turn the tool on, push the
lock-off lever (B) toward the back of
the tool, then depress the paddle
switch (A). 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.
