the tool to rest on the work surface
without moving, or moving the tool in
a circular motion causes burning and
swirling marks on the work surface.
6. Remove the tool from the work surface
before turning the tool off. Allow the tool
to stop rotating before setting it down.
Use extra care when working over an
edge, as a sudden sharp movement of
grinder may be experienced.
MOUNTING AND USING CUTTING
(TYPE 1) WHEELS
Cutting wheels include diamond wheels and
abrasive discs. Abrasive cutting wheels for
metal and concrete use are available. Diamond
blades for concrete cutting can also be used.
A closed, 2-sided type 1 cutting wheel guard
is included with this tool and is re quired when
using cutting wheels. Fail ure to use proper
flange and guard can re sult in injury resulting
from wheel breakage and wheel contact. See
pages 10 and 11 for more information.
MOUNTING CLOSED (TYPE 1) GUARD
Turn off tool and remove battery before
making any adjustments or removing or
installing attachments or accessories.
1. Open the guard latch (10), and align the
arrow on the guard (9) with the arrow on
the hub (11). This will align the lugs with
slots on the gear case cover. Position
the guard facing backward.
2. Push the guard down until the guard lug
engages and rotates freely in the groove
on the gear case hub.
3. Rotate guard (9) 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. 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
: The guard is pre-adjusted to the
dia met er of the gear case hub at the factory.
If, after a period of time, the guard becomes
loose, tighten the adjusting screw (12) with
the clamp lever in the closed position with
guard installed on the tool.
Do not tighten adjusting screw with clamp
lever in open position. Undetectable damage
to guard or mounting hub may result.
MOUNTING CUTTING WHEELS
Turn off tool and remove battery before
making any adjustments or removing or
installing attachments or accessories.
Matching diameter backing flange and
threaded 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 included wrench.
5. To remove the wheel, depress the
spindle lock button and loosen the
threaded clamp nut with included wrench.
USING CUTTING WHEELS
Do not use edge grinding/cutting wheels for
surface grinding 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
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
CLEANING
Blowing dust and grit out of the motor
housing using compressed air is a necessary
maintenance procedure. Dust and grit from
metal grinding often accumulate on interior
surfaces and could create an electrical
shock hazard if not cleaned out.
• Always handle accessories with care
when mounting or removing.
• The best storage place for accessories is
one that is cool and dry away from direct
sunlight and excess heat or cold.
WARNING:
glasses. Everyday eyeglasses are NOT
safety glasses. Also use face or dust mask
if cutting operation is dusty. ALWAYS
WEAR CERTIFIED SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.
Use only mild soap and a damp cloth to clean
the tool. Never let any liquid get inside the tool;
