2. Push the guard down until the
M
O
N
guard lugs engage and rotate
freely in the groove on the gear
case hub.
3. With the guard latch open, rotate the
guard (I) into the desired working
position. The guard body should
be positioned between the spindle and the operator to provide
maximum operator protection.
4. Close the guard latch to secure the guard
I
on the gear case. You should not be able
to rotate the guard by hand when the
latch is closed. Do not operate the grind-
er with a loose guard or the clamp lever
in open position.
5. To remove the guard, open the guard latch, rotate the guard so
that the arrows are aligned and pull up on the guard.
NOTE: The guard is pre-adjusted to the
P
diameter of the gear case hub at the fac-
tory. If, after a period of time, the guard
becomes loose, tighten the adjusting screw
(P) with clamp lever in the closed position.
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
recom mended 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 be fore 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.
