Pressure Relief Procedure

Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
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 Proce-
dure when you stop spraying and before cleaning,
checking, or servicing the equipment.
1. Turn engine OFF.
2. Release pressure on bead tank to 0 psi (0 bar, 0
MPa). Turn pressure relief valve (8) to vertical posi-
tion and watch bead tank pressure gauge until pres-
sure reads 0 psi (0 bar, 0 MPa). Do not use safety
valve (3) to release pressure from bead tank.

(0 bar, 0 MPa) and open lid.
4. Secure lid over opening and tighten wing nut until lid
is level with hopper.
