WARNING:

Turn off and unplug the tool before making any adjustments or 

removing or installing attachments or accessories. 

Before reconnecting the tool, 

depress and release the paddle switch to ensure that the tool is off.

WARNING:

 Guards must be used with all grinding wheels, sanding flap discs, wire 

brushes, and wire wheels. The tool may be used without a guard only when sanding 

with conventional sanding discs. Some D

E

(Type 27) and hubbed grinding wheels (Type 27). 

The same guard is designed for use with sanding 

flap discs (Type 27 and 29) and wire brushes. 

Grinding and cutting with wheels other than Type 

27 and 29 require different accessory guards not 

included with tool. Mounting instructions for 

these accessory guards are included in the 

accessory package.
  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 lugs engage        

I

and rotate freely in the groove on the gear case hub.

  3.  With the guard latch open, rotate the guard (I) into    

the 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. You should not be able to rotate the guard by hand when the latch is 

closed. Do not operate the grinder with a loose guard or the 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

P

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

the guard becomes loose, tighten the adjusting screw 

(P) with clamp lever in the closed position.

CAUTION:

 If guard cannot be tightened by adjusting 

clamp, do not use tool and take the tool and guard to 

a service center to repair or replace the guard.

CAUTION:

 Do not tighten the adjusting screw with the clamp lever in open position. 

Undetectable damage to the guard or the mounting hub may result.

OPERATION

Guards and Flanges

It is important to choose the correct guards and flanges to use with the grinder 

accessories. See pages 7–8 for the correct accessories.

NOTE:

 Edge grinding and cutting can be performed with Type 27 wheels designed and 

specified for this purpose.

WARNING:

  Accessories must be rated for at least the speed recommended on the 

tool warning label. Wheels and other accessories running over rated accessory speed 

may burst and cause injury. Every unthreaded accessory must have a 22 mm (7/8") 

arbor hole. If it does not, it may have been designed for a circular saw and should not 

be used. Use only the accessories shown on pages 7–8. Accessory ratings must be 

above listed minimum wheel speed as shown on tool nameplate.

 Switches 

WARNING:

  Hold the side handle and body of the tool firmly to maintain control of 

the tool at start up and during use and until the wheel or accessory stops rotating. 

Make sure the wheel has come to a complete stop before laying the tool down.

NOTE:

 To reduce unexpected tool movement, do not switch the tool on or off while 

under load conditions. Allow the grinder to run up to full speed before touching the 

work surface. Lift the tool from the surface before turning the tool off. Allow the tool 

to stop rotating before putting it down.
