Pressure Relief Procedure

WARNING

SKIN INJECTION HAZARD

Fluid under high pressure can be in-

jected through the skin and cause

serious injury. To reduce the risk of an

injury from injection, splashing fluid, or moving

parts, follow the Pressure Relief Procedure

whenever you:

D Are instructed to relieve the pressure

D Stop spraying/dispensing

D Check or service any of the system equipment

D Install or clean the spray tip/nozzle

1. Lock the gun/valve trigger safety.

2. Turn off the hydraulic supply line valve (E) first,

then the return line valve (R).

3. Unlock the gun/valve trigger safety.

4. Hold a metal part of the gun/valve firmly to a

grounded metal waste container and trigger it to

relieve the fluid pressure.

5. Lock the trigger safety.

6. Open the pump drain valve (required in your

system), having a container ready to catch the

drainage.

7. Leave the drain valve open until you are ready to

spray again.

If you suspect that the spray tip or hose is completely

clogged, or that pressure has not been fully relieved

after following the steps above, very slowly loosen the

hose end coupling and relieve pressure gradually, then

loosen completely. Now clear the tip or hose obstruc-

tion.
