Daily Care and Cleaning

CAUTION

• Clean all parts with a non-conductive, compatible solvent. Conductive solvents can cause the gun to malfunction.

Do not immerse the gun in fluid.

• Do not use methylene chloride as a flushing or cleaning solvent with this gun as it will damage nylon components.

• Fluid in the air passages could cause the gun to malfunction and could draw current and reduce the electrostatic effect. Fluid in the power supply cavity can reduce the alternator life. Whenever possible, point the gun down when cleaning it. Do not use any cleaning method which could allow fluid into the gun air passages.

Do not point the gun up while cleaning it.
