Supply System Operation
Before Operating
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Lock the gun/valve trigger.
2. See F
IG
. 2, page 6.
a. Close the air motor ball valve (BF) and the main
air slider valve (BA).
b.
If the RAM is in a raised position,
set the ram
director valve (BC) to DOWN. The ram will
slowly drop.
c. Jog the director valve up and down to bleed air
from ram cylinders.
3. Unlock the gun/valve trigger.
4. Hold a metal part of the gun/valve firmly to the side
of a grounded metal pail, and trigger the gun/valve
to relieve pressure.
5. Lock the gun/valve trigger.
If you suspect that the spray tip/nozzle or hose is com-
pletely clogged, or that pressure has not been fully
relieved after following the steps above,
very slowly
loosen the tip guard retaining nut or hose end coupling
and relieve pressure gradually, then loosen completely.
Now clear the tip/nozzle or hose.
Flush Before Using Equipment
The pump was tested with lightweight oil, which is left in
the fluid passages to protect parts. To avoid contaminat-
ing fluid with oil, flush the pump with a compatible sol-
vent before use. See
Flush on page 12.
NOTICE
To prevent mixed material from fully curing in the
system requiring replacement of all parts containing
cured material, always be prepared to immediately
begin flushing at the first sign of material curing in the
system and immediately after spraying stops. See
Flush on page 12.
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.
NOTICE
Prolonged exposure to solvent will reduce the life of
the wiper. For maximum performance, do NOT soak
platen soft parts in solvent. Instead, gently wipe down
soft parts with solvent.
