4. Maintain contact between the edge of the wheel and the work surface with wire
wheels.
5. Continuously move the tool in a forward and back motion to
avoid creating gouges in the work surface. Allowing 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 cutting wheel guard is included with this tool and is re-
quired when using cutting wheels. Failure to use proper flange and guard can result in
injury resulting from wheel breakage and wheel contact. See pages 13 and 14 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 diameter 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 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 included wrench.
5. To remove the wheel, grasp and turn the wheel while depressing the spindle lock button.
