USING WIRE CUP BRUSHES AND WIRE WHEELS (FIG. 16)

Wire wheels and brushes can be used for removing rust, scale and paint, and for smoothing irregular surfaces.

NOTE: The same precautions should be taken when wire brushing paint as when sanding paint (refer to Precautions To Take When Sanding Paint).

1.

Allow the tool to reach full speed before touching

FIG. 16

 

the tool to the work surface.

 

 

2.

Apply minimum pressure to work surface,

 

 

allowing the tool to operate at high speed.

 

 

Material removal rate is greatest when the tool

5˚–10˚

 

operates at high speed.

3. Maintain a 5° to 10° angle between the tool and work surface for wire cup brushes.

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

MOUNTING TYPE 27 OR TYPE 1 GUARD

1.Open the guard latch (M), and align the lugs (N) on the guard with the slots on the hub (O). 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.

to stop rotating before setting it down.

CAUTION: Use extra care when working over an edge, as a sudden sharp movement of grinder may be experienced.

Mounting and Using Cutting Disc

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 Type 27 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 10–11 for more information.

NOTE: The guard is pre-adjusted to the diameter of the

FIG. 21

gear case hub at the factory. If, after a period of time,

P

the guard becomes loose, tighten the adjusting screw

 

(P) with the guard latch in the closed position with

 

guard installed on the tool.

 

NOTICE: To reduce the risk of damage to the tool, do not tighten adjusting screw with guard latch in open position. Undetectable damage to guard or mounting hub may result.
