SAFETY PRECAUTIONS The Hydra-Spray equipment develops extremely high material pressure which remains in the system until relieved by shutting off theair to pump and releasing the material pressureby opening manifold dump valve. In operation, ifthe fine high pressure streamof material released from spray gun is allowed to come in direct contact with the hand or any part of human body it could penetrate the skin and cause physical harm. suspension and held there dbring the entire spray HANDLE THE HYDFA-SPRAY GUN AS CAUTIOUSLY AS YOU WULU ANYGUN: LO-OR UNLOADED.

Always be sure that the equipment supplying the material'to spraygun is properly grounded to prevent sparking. The high velocity flow of material through the spray tipmay cause static electricity to bedeveloped. Use only metal braid material dispensing hoses or static pro- tected hose. Also be sure to providefor the proper grounding out of the compressor. .. PREVENTIVE MAINTENANCE filter cartridge or screen, if used. Close drain valve.
