high pressure can penetrate the human skin and can cause severe 

injury, possibly resulting in amputation or death. Hot liquids and 

chemicals can also cause burns or injury. If any part of the body comes 

in contact with the spray stream, immediately consult a physician.

only genuine factory repair parts supplied by Spraying Systems Co.

DO NOT

 exceed maximum operating pressure of the lowest rated 

accessory item within the spray system even though some of the 

accessories have a higher maximum pressure rating. 

5.

 

DO NOT

 leave equipment under pressure unattended at any time. 

Relieve pressure by shutting off power to pump, turning off the liquid 

supply to the pump, and actuating Trigger until all fluid ceases to flow;
