8-3 Cleaning (Optic)
Wipe clean the Glass Rod tip with an alcohol-immersed cotton swab. Remove all debris and oil (Fig. 7).
CAUTION
Do NOT use a sharp tool to clean the Glass Rod. It could damage the glass and reduce the light
transmission.
8-4 Cleaning (Spray Port)
When spray ports are clogged, or spray does not exit evenly from the ports, clean the ports (Fig. 8).
CAUTION
Do not forcibly insert the wire into the port. Resultant port damage could cause the spray to be
directed away from the bur, and the cooling efficiency reduces.
Do not blow air into the Clean Head Hole.
