 Mounting and Using Wire Brushes and Wire Wheels

Wire cup brushes or wire wheels screw directly on the grinder spindle without the use 

of flanges. Use only wire brushes or wheels provided with a 14M2 threaded hub. A 

Type 27 guard is required when using wire brushes and wheels.

WARNING: Wear work gloves when handling wire brushes and wheels. 

They can 

become sharp.

CAUTION: 

Wheel or brush must not touch guard when mounted or while in use. 

Undetectable damage could occur to the accessory, causing wires to fragment from 

accessory wheel or cup.

MOUNTING WIRE CUP BRUSHES AND WIRE WHEELS

WARNING: Turn off and unplug the tool before making any adjustments or 

removing or installing attachments or accessories.

 Before reconnecting the tool, 

turn the switch on and off as previously described to ensure that the tool is off.
  1.  Thread the wheel on the spindle by hand.
  2.  Depress spindle lock button and use a wrench on the hub of the wire wheel or 

brush to tighten the wheel.

  3.  To remove the wheel, reverse the above procedure.
CAUTION: Failure to properly seat the wheel hub before turning the tool on may result 

in damage to tool or wheel.

USING WIRE CUP BRUSHES AND WIRE WHEELS

Wire wheels and brushes can be used for removing rust, scale and paint, and for 

smoothing irregular surfaces.
  1.  Allow the tool to reach full speed before touching 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 operates at high speed.

  3.  Maintain a 5

˚

 to 10

˚

 angle between the tool and 

5

˚

-10

˚

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 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 (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, 2-sided cutting wheel guard is not included with this tool but 

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 page 8 for more 

information.

making any adjustments or removing or installing 

attachments or accessories.

 Before reconnecting 

the tool, turn the switch on and off as previously 

described to ensure that the tool is off.
  1.  Open the guard latch (M). Align the lugs  (N) on 

the guard with the slots (O) on the gear case.

  2.  Push the guard down until the guard lug engages    

I

and rotates freely in the groove on the gear case 

hub.

  3.  Rotate guard (I) into desired working position. 

The guard body should be positioned between 

the spindle and the operator to provide maximum 

operator protection.
