8. Spray Port Maintenance
When the spray ports are clogged, or spray does not exit evenly from the ports, clean the
ports as follows:
1) Remove the bur from the chuck.
2) Take out the cleaning wire from the back end of the brush holder. Insert the wire straight
into the spray ports with caution.
Do not forcibly insert the wire into the port.
Damaged or disoriented port could cause the spray to diverge or be directed away from the
bur, and the cooling efficiency deteriorates.
3) After use, clean the cleaning wire. Push into the brush holder with the pointed end of the
wire inward.
