INSTALLING THE COLLET TO THE DIE GRINDER

1. Select the grinding stone you require.

2. Two collets of different sizes are 

provided. Select whichever fits 
the shank of the stone you have 
chosen.

• The larger collet is probably 

already installed in the grinder.

3. If the other collet is to be used, 

undo the screw cap completely 
and pull out the collet from the 
collet seat. Replace it with the 
new collet and screw the cap loosely back on.

FITTING THE GRINDING STONE INTO THE DIE GRINDER

IMPORTANT: Never use chipped or cracked grindstones.

Never use 

grindstones not rated to operate at a speed equal to, or greater than, the 
full operating speed of the air tool.

1. Slip the shank of the chosen stone 

into the collet and tighten the 
screw cap finger tight.

2. Place the smaller of the two 

wrenches over the collet seat to 
stop the tool from rotating.

3. Use the larger wrench to fully 

tighten the collet and grip the 
stone in position as shown.
