3. Thread the flaring cup wheel on spindle by hand, seating wheel
against backing flange.
4. Depress the spindle lock button and tighten the wheel by hand.
5. To remove the wheel, reverse the above procedure.
CAUTION: Failure to properly seat the wheel against backing
flange before turning the tool on may result in damage to the tool or
the wheel.
NOTE: Adjust the guard skirt so that only 1/8" (3 mm) of the wheel is
exposed below the skirt.
USING A FLARING CUP WHEEL
Flaring cup wheels are designed for heavy material removal.
1. Allow the tool to reach full speed before touching tool to work
surface.
2. Apply minimum pressure to work surface, allowing the tool to
operate at high speed.
3. Maintain a 5˚ to 10˚ angle between the tool and the work surface.
4. Continuously move the tool in a forward and back motion to avoid
creating gouges in the work surface.
5. Remove the tool from work surface before turning tool off. Allow
the tool to stop rotating before setting it down.
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.
WARNING: A closed, cutting wheel guard is not included with
this tool. Cutting wheels require proper flanges and guards. A 7"
(180 mm) cutting guard, is available as an accessory and includes
proper, matching flanges. Failure to use proper flange and guard can
result in injury resulting from wheel breakage and wheel contact.
MOUNTING CLOSED (TYPE 1) GUARD
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. Before reconnecting the tool, depress and
release the trigger switch to ensure that the tool is off. An
accidental start-up can cause injury.
1. Align the lugs with slots on the gear case cover. Position the
guard facing backward, as shown.
2. Push the guard down until the guard lug engages and rotates
freely in the groove on the gear case hub.
3. Rotate guard into desired working position. The guard body
should be positioned between the spindle and the operator to
provide maximum operator protection.
4. 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.
NOTE: The guard is preadjusted to the diameter of the gear case
hub at the factory. If, after a period of time, the guard becomes loose,
tighten the adjusting screw.
MOUNTING CUTTING WHEELS
1. Remove mount.
2. Install wheel backing flange, aligning flats on spindle with flats on
backing flange.
3. Place the wheel on the backing flange, centering the wheel on the
backing flange pilot.
4. Install the clamp nut, ensuring that the wheel remains centered on
the backing flange.
5. Depress the spindle lock button and tighten clamp nut with
wrench.
6. Reverse the above procedure to remove the wheel.
