USING A FLARING CUP WHEEL (FIG. 17)

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 (Fig. 18, 19)

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, two-sided cutting wheel guard is included with this tool and is required when using cutting wheels. Failure to use proper flange and guard can result in injury resulting from wheel breakage and wheel contact. See pages 62–64 for more information.

MOUNTING CLOSED (TYPE 1) GUARD

1.Open the guard latch (K), and align the lugs (L) on the guard with the slots on the hub (M). 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 (F) 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 with the guard latch in open position.

5.To remove the guard, follow the procedure above in reverse order.

NOTE: The guard is pre-adjusted to the

MOUNTING CUTTING WHEELS (FIG. 20)

CAUTION: Matching diameter threaded backing flange and clamp nut (included with tool) must be used for cutting wheels.

1.Install wheel backing flange, aligning flats on spindle (T) with flats on backing flange (O).

2.Place the wheel on the backing flange, centering the wheel on the backing flange pilot.

3.Install the clamp nut, ensuring that the wheel remains centered on the backing flange.
