Warning! Use of this tool can generate and/
or disperse dust, which may cause serious and
permanent respiratory or other injury. Always use
NIOSH/OSHA approved respiratory protection appropriate
for the dust exposure. Direct particles away from face and
body.
Caution! Wear appropriate hearing protection during
use. Under some conditions and duration of use, noise
from this product may contribute to hearing loss.
f Do not operate this tool for long periods of time.
Vibration caused by the operating action of this tool
may cause permanent injury to fingers, hands, and
arms. Use gloves to provide extra cushion, take
frequent rest periods, and limit daily time of use.
Motor
Be sure your power supply agrees with nameplate
marking. Do not operate AC tools on DC. This information
is printed on the nameplate. All Black & Decker tools are
factory-tested; if this tool does not operate, check the
power supply.
Extension cord
Make sure the extension cord is in good condition before
using. Always use the proper size extension cords with the
tool – that is, proper wire size for various lengths of cord
and heavy enough to carry the current the tool will draw.
Use of an undersized cord will cause a drop in line voltage
resulting in loss of power and overheating.
ASSEMBLY
Warning! To prevent accidental operation, turn
off and unplug tool before performing the following
operations. Failure to do this could result in serious
personal injury.
Attaching the wheel guard (Fig. B)
Warning! Never grind or brush without guard in
place.
f Place the tool on a table, with the spindle (9) facing up.
f Place the spring washer (8) over the spindle and
locate it on the shoulder (10).
f Place the guard (5) onto the tool as shown.
f Place the flange (7) over the spindle with the
protruding pips towards the guard.Make sure that the
holes in the flange align with the screw holes.
f Secure the flange with the screws (6). Make sure that
the screws are fully tight and that the guard can be
rotated.
Removing the wheel guard - for sanding only
(Fig. C)
Caution! To prevent loss of control, do not set tool down
until accessory has completely stopped turning. This tool
is fitted with a guard. For sanding only, you can remove the
guard as follows:
f Remove the outer flange, disc and inner flange if they
have been attached.
f Use a screwdriver to remove the screws (6).
f Remove the flange (7), guard (5) and spring washer
(8). Store these parts carefully.
Adjusting the guard
The guard can be rotated 90°.
f Rotate the guard as required.
Fitting the side handle
f A three position auxiliary handle (3) is furnished with
your grinder and can be screwed into either side of the
grinder housing as well as into the top.
Warning! This handle SHOULD BE USED AT ALL
TIMES to maintain complete control of the tool. Always
make sure the handle is tight.
Fitting and removing depressed center wheels
(Fig. D, E y F)
Caution! Never use any depressed-center wheels
without the proper guard.
f Fit the guard as described above.
f Place the inner flange (11) onto the spindle (9), as
shown (Fig.D). Make sure that the flange is correctly
located on the flat sides of the spindle.
f Place the disc (12) onto the spindle (9), as shown
(Fig.4). If the disc has a raised center (13), make sure
that the raised center faces the inner flange.
f Make sure that the disc locates correctly on the inner
flange.
f Place the outer flange (14) onto the spindle. When
fitting a grinding disc, the raised center on the outer
flange must face towards the disc (A in Fig. E). When
fitting a cutting disc, the raised center on the outer
flange must face away from the disc (B in Fig. E).
f Keep the spindle lock (4) depressed and tighten the
outer flange using the two-pin spanner (15)(Fig.F).
f When using a depressed-center wheel, hold the tool
so that an angle of approximately 30° exists between
the wheel and the work.
f When using ready-mount or hubbed wheels, flanges
are not required.
Warning! Check rated speed on depressed-center
wheel. Never use a wheel with rated speed lower than the
speed on the nameplate of the tool.

Edge grinding

Edge grinding may be done with Type 27 depressed center
wheels specifically designed for this purpose. These
wheels are available locally. They must not be subject to
side pressure.
