Grounding
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes
to ignite or explode. Grounding provides an escape
wire for the electric current.
• Pump: Order Grounding Wire and Clamp Kit,
Part No. 222011. See Grounding the Pump and

Pressure Relief Procedure

This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief
Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.
The system pressure must be manually relieved to pre-
vent the system from starting or dispensing accidentally.
For the following instructions, see F
1. Shut off hydraulic power supply.
2. Close supply line shut-off valve (L).
3. Open dispensing valve to relieve pressure.
4. Open pump outlet drain valve. Have a container
5. Close return line shut-off valve (H).
6. If you suspect the nozzle or hose is completely
