CAUTION: Do not tighten the adjusting screw with the clamp
lever in open position. Undetectable damage to the guard or the
mounting hub may result.
CAUTION: If guard cannot be tightened by adjusting clamp, do
not use tool and take the tool and guard to a service center to repair
or replace the guard.
OPERATION
Guards and Flanges
It is important to choose the correct guards and flanges to use
with the grinder accessories. See pages 6–8 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
accessories 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 6–8. 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
wheel or accessory stops rotating. Make sure the wheel has come
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.
SOFT START FEATURE
The soft start feature allows a slow speed build-up to avoid an initial
jerk when starting. This feature is particularly useful when working in
confined areas. Current surge will also be reduced.
PADDLE SWITCH (D28114, D28114N, D28144, D28144N)
CAUTION: Before connecting the tool to a power source depress
and release the paddle switch (A) once without depressing the
lock-on button (Fig. 1, J) [D28114, D28144 only] 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 (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.
SLIDER SWITCH (D28131, D28140)
CAUTION: Before connecting the tool to a power supply, be sure
the switch is in the off position by pressing the rear part of the switch
and releasing. Ensure the switch is in the off position 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 start the tool, slide the ON/OFF switch
(L) toward the front of the tool. To stop the
