INSTALLING/REPLACING GRINDING WHEEL

See Figure 2, page 13.

WARNING:

Thoroughly inspect a new grinding wheel before 
you install it on the grinder.

•  Tap  lightly  around  the  wheel  using  a  wooden 

 hammer.

•  Listen carefully to the resulting sounds. Places 

with fissures or cracks will result in a different 
sound.

Do not use a wheel containing fissures or cracks.
When you install a new grinding wheel, carry out a 
no load revolution test of approximately one minute 
with the grinding wheel facing a safe direction, i.e., 
away from people or objects.

  Unplug the grinder.

  Depress the spindle lock button and rotate the clamp 

nut until the spindle locks. 

NOTE: 

To prevent damage to the spindle or spindle lock, 

always allow motor to come to a complete stop before 
engaging spindle lock. 

  Loosen and remove the clamp nut

 

from the spindle. Do 

not remove the disc flange.

  Make sure the flats on the bottom of the disc flange are 

engaged with the flats on the spindle.

  Place the grinding wheel over the spindle. 

  Thread the clamp nut

 

on the spindle with the flat side of 

the nut facing up. 

  Fit the raised, small diameter portion of the clamp nut

 

 

into the hole in the wheel and finger tighten.

WARNING:

Always install a grinding wheel with the depressed 
center against the disc flange. Failure to do so 
will cause the grinding wheel to crack when 
tightening the clamp nut. This could result in 
serious personal injury because of loose particles 
breaking off and being thrown from the grinder. Do 
not overtighten.

  Depress the spindle lock button and rotate the wheel 

clockwise until the spindle locks in position.

  Tighten the clamp nut

 

 securely with the wrench 

provided. Do not overtighten.

DANGER:

Never attach a TYPE 1 straight or cut-off wheel to 
this angle grinder. It is only designed for grinding. 
Use for any other purpose is not recommended 
and creates a hazard, which will result in serious 
injury.

ATTACHING THE SIDE HANDLE

See Figure 3, page 13.

  Unplug the grinder.

  Screw the handle into the side of the gear housing.

 

NOTE: 

You can install the handle on either the left or right 

side of the grinder, depending on operator preference. 
It must always be used to prevent loss of control and 
possible serious injury.

  Tighten the side handle securely.

POSITIONING THE GUARD

See Figures 4 - 6, page 13

The guard on the grinder should be correctly installed de-
pending on which side the handle is mounted. Never use 
the grinder without the guard correctly in place or when the 
index arrows are aligned.
