Mounting Guard
MOUNTING AND REMOVING GUARD
WARNING:
Turn off and unplug the tool before making any adjustments or
removing or installing attachments or accessories.
Before reconnecting the tool,
depress and release the paddle switch to ensure that the tool is off.
WARNING:
Guards must be used with all grinding wheels, sanding flap discs, wire
brushes, and wire wheels. The tool may be used without a guard only when sanding
with conventional sanding discs. Some D
E
WALT models are provided with a guard
intended for use with depressed center wheels
N
O
M
(Type 27) and hubbed grinding wheels (Type 27).
The same guard is designed for use with sanding
flap discs (Type 27 and 29) and wire brushes.
Grinding and cutting with wheels other than Type
27 and 29 require different accessory guards not
included with tool. Mounting instructions for
these accessory guards are included in the
accessory package.
1. Open the guard latch (M). Align the lugs (N)
on the guard with the slots (O) on the gear
case.
2. Push the guard down until the guard lugs engage
I
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 on the
gear case. You should not be able to rotate the guard by hand when the latch is
closed. Do not operate the grinder 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 diameter of the
P
gear case hub at the factory. If, after a period of time,
the guard becomes loose, tighten the adjusting screw
(P) with clamp lever in the closed position.
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.
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.
OPERATION
Guards and Flanges
It is important to choose the correct guards and flanges to use with the grinder
accessories. See pages 7–8 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 22 mm (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 7–8. Accessory ratings must be
above listed minimum wheel speed as shown on tool nameplate.
Switches
WARNING:
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.
