MAINTENANCE

PREVENTIVE MAINTENANCE

Turn off air and coating supply and
relieve pressure in the supply lines, or
disconnect from airline and fluid line.
1. Remove air cap (1) and clean. If any of the holes
in the cap are blocked with coating material use
a toothpick to clean. Never use metal wire which
could damage the cap and produce distorted
