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 one wrench over the collet
seat to stop the tool from rotating.
3. Use the other wrench to fully
tighten the collet and grip the
stone in position as shown.
OPERATING THE DIE GRINDER
1. Use your thumb to slide the
throttle locking lever forward while
squeezing the trigger against the
body of the tool.
2. Do not use excess pressure on the
grinding stone as this will shorten
its life.
3. Release the trigger to stop the
grinder.
• The tool will continue to rotate
very briefly after the trigger has been released.
Always ensure the grinder has stopped before putting it down.
SETTING THE SPEED
1. Adjust the tool speed by setting
the air regulator on top of the tool
body using a suitable screwdriver.
DISCONNECTING THE AIR SUPPLY
1. Do not disconnect the air supply hose until the compressor has been shut
down and the compressed air released.
