Maintenance - DeWalt D28065-XE Instruction Manual

2. Push the guard down until the guard lug engages
and rotates freely in the groove on the gear case
hub.
3. Rotate guard (D) into 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 cover. You should be unable to rotate
the guard by hand when the latch is in closed
position. If rotation is possible, tighten the
adjusting screw (M) with clamp lever in the
closed position. Do not operate grinder with a
loose guard or 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: If, after a period of time, the guard becomes loose, tighten the adjusting screw
(M) with the clamp lever in the closed position.
CAUTION: Do not tighten adjusting screw with clamp lever in open position.
Undetectable damage to guard or mounting hub may result.
MOUNTING CUTTING WHEELS
CAUTION: Turn off and unplug the tool before making
any adjustments or removing or installing attachments or
accessories. Before reconnecting the tool, turn the switch
on and off as previously described to ensure that the tool
is off.
CAUTION: Matching diameter threaded backing flange
and clamp nut (included with tool) must be used for cutting
wheels.
1. Place the unthreaded backing flange on spindle with the
raised section (pilot) facing up. The raised section (pilot)
on the backing flange will be against the wheel when the
wheel is installed.
2. Place the wheel on the backing flange, centering the wheel on the raised section
(pilot).
3. Install the threaded clamp nut with the raised section (pilot) facing away from
the wheel.
4. Depress the spindle lock button and tighten clamp nut with a wrench.
5. To remove the wheel, grasp and turn while depressing the spindle lock button.
USING CUTTING WHEELS
WARNING: Do not use edge grinding/ cutting wheels for surface grinding
D
applications because these wheels are not designed for side pressures encountered
with surface grinding. Wheel breakage and injury may result.
1. Allow tool to reach full speed before touching tool to work surface.
2. Apply minimum pressure to work surface, allowing tool to operate at high
M
speed. Cutting rate is greatest when the tool operates at high speed.
3. Once a cut is begun and a notch is established in the workpiece, do not change
the angle of the cut. Changing the angle will cause the wheel to bend and may
cause wheel breakage.
4. Remove the tool from work surface before turning tool off. Allow the tool to stop
rotating before setting it down.

MAINTENANCE

WARNING: To reduce the risk of serious personal injury, turn tool off and
disconnect tool from power source before making any adjustments or removing/
installing attachments or accessories.
Cleaning
WARNING: Blowing dust and grit out of motor and switch actuator using clean,
dry compressed air is a necessary regular maintenance procedure. Dust and grit
containing metal particles often accumulate on interior surfaces and could create an
electrical shock or electrocution if not frequently cleaned out. It is recommended that
a ground fault circuit interrupter (GFCI) is utilized to further protect the user from
electric shock resulting from the accumulation of conductive particles. If the tool is
deactivated by the GFCI, unplug the tool and check and clean the tool before resetting
the GFCI. ALWAYS WEAR SAFETY GLASSES when cleaning or using this tool.
CAUTION: Never use solvents or other harsh chemicals for cleaning the
non-metallic parts of the tool. Use a clean, dry cloth only. Never let any liquid get
inside the tool; never immerse any part of the tool into a liquid.
