INSTALLING THE COLLET

1. Select the grinding stone you require.

2. Three 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 another 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

IMPORTANT: Never use chipped or cracked grindstones.

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.

ADJUSTING THE SPEED

1. Set the tool speed by rotating the

control to one of the four settings.

• The graduations on the speed

control indicate the speed

setting when aligned with the

reference mark on the air inlet.

• Speeds available are: 12000,

17500, 22000 or 25000 rpm (+/-

10%).
