Pressure Relief Procedure

WARNING

SKIN INJECTION HAZARD: This sprayer builds up an internal pressure of

1000 psi (6.9 MPa, 69 bar) during use. To help prevent serious injury from pressurized fluid, such as skin injection and splashing fluid, follow this Pressure

Relief Procedure whenever you stop spraying and before cleaning, checking, servicing, or transporting equipment.

ELECTRIC SHOCK HAZARD: AC powered (corded) equipment must be grounded. Improper grounding, setup, or usage of the equipment can cause electric shock. Turn off and disconnect power cord before servicing the equipment.

2.

Turn Prime Knob downward to PRIME position to relieve pressure.

NOTICE

Removing the pump locking device or spinning the gear before installation will permanently damage the pump. Do not turn the pump gear before installing the enclosure cover.

1.

Disconnect power (remove battery or unplug power cord).

Use only genuine Graco replacement parts.

The use of non-Graco replacement parts may void warranty .
