DO NOT install the spray tip in the gun yet.
Install an air line filter (H) in the main air line, to re- move harmful dirt and moisture from the compressed air supply. Install a bleed±type master air valve (J) close to the pump air inlet, and downstream from the pump air regulator (K). Install a second bleed valve (L) upstream from all other accessories, to isolate the accessories for servicing.Connect an air supply hose between the main air supply line and the sprayer's air inlet swivel (1).
CAUTION
To avoid contaminating the air supply to the gun, do not use an automatic air line lubricator; lubricate the motor manually, instead. See OPERATION on page 11.

The air relief valve (supplied) opens automatically to relieve air pressure to the pump if the pressure exceeds a preset level. This valve prevents over- pressurization of the spray gun.
The fluid drain valve assists in relieving fluid pres- sure in the displacement pump, hose, and gun; triggering the gun to relieve pressure may not be sufficient.
