Operation
Pressure Relief Procedure
1. Lock the gun/valve trigger.
2. For D200 Air Controls: See F
a. Close the air motor slider valve (AF) and the
main air slider valve (AA).
b. Set the ram director valve (AC) 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.
6. Open the fluid line drain valve and the pump bleeder
valve (P). Have a container ready to catch the drain-
age.
7. Leave the pump bleeder valve (P) open until ready
to spray again.
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 pump manual for flushing
directions.

Start and Adjust Ram
Moving parts can pinch or amputate fingers. When the
pump is operating and when raising or lowering the
ram, keep fingers and hands away from the pump
intake, platen, and lip of the drum.
1. Refer to F
. 1. Close all air regulators and air
IG
valves.
2. Open main air slider valve (AA) and set ram air reg-
ulator (AB) to 40 psi (0.28 MPa, 2.8 bar). Set direc-
tor valve handle (AC) to UP and let the ram rise to
its full height. See F
IG
3. Lubricate the platen seals (B) with grease or other
lubricant compatible with the fluid you will pump.
4. Remove the drum cover and smooth the surface of
the fluid with a straightedge.
5. Put a full drum of fluid on the ram base, slide it back
against the drum stops, and center it under the
platen (B). An optional drum roller kit is available for
D200 and D200s rams to make it easier to load the
drum on the base. Order Kit 255627.
NOTICE
To avoid damage to the platen seals, do not use a
drum that is dented or damaged.
