Pressure Relief Procedure

WARNING

Read warnings, page 7. Relieve pressure before 
cleaning or repairing gun.

1.

Engage piston safety lock, page 10.

CAUTION

Air supply is required for gun actuation. Do not dis-
connect gun air supply until fluid pressure is relieved.

2.

Close fluid valves A and B. Leave air valve (W) 

open.

3.

Disengage piston safety lock, page 10.

W

TI2410A

4.

Trigger gun onto cardboard or into waste container 

to relieve pressure.

5.

Engage piston safety lock, page 10.

WARNING

Fluid in the hose and proportioner is still under pres-
sure. Follow the Pressure Relief Procedure in the pro-
portioner manual.

To relieve pressure in the hose after the gun is 
removed, place the fluid manifold over containers, fac-
ing away from you. Very carefully open the fluid valves. 
Under high pressure, fluid will spray sideways from the 
fluid ports.
