Maintenance

Pressure Relief Procedure

The system pressure must be manually relieved to pre­vent the system from starting or spraying accidentally.
Fluid under high pressure can be injected 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:

• are instructed to relieve the pressure,

• stop spraying,

• check or service any of the system equipment,

• or install or clean the spray tip.

1. Lock gun trigger safety.

2. Turn engine ON/OFF switch to OFF.

3. Move pump valve to OFF (down) and turn pressure control
knob fully counter clockwise.

4. Unlock trigger safety. Hold metal part of gun firmly to side of
grounded metal pail, and trigger gun to relieve pressure.

5. Lock gun trigger safety.

6. Open pressure drain valve. Leave valve open until 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

tip guard retaining nut or hose end coupling to relieve
pressure gradually, then loosen completely. Now clear
tip or hose.

Maintenance
