Air and Fluid Hoses
Be sure all air hoses (AI) and fluid hoses (AH) are properly sized and pressure-rated for your system. Use only
electrically conductive hoses. Fluid hoses must have
spring guards on both ends. Use of a short whip hose
and a swivel between the main fluid hose and the
gun/valve allows freer gun/valve movement.

Before Beginning Repair
Grounding
The equipment must be grounded. Grounding
reduces the risk of static and electric shock by providing an escape wire for the electrical current due to
static build up or in the event of a short circuit.
Pump: use a ground wire and clamp. Loosen grounding
lug locknut and washer. Insert one end of a 1.5 mm2(12
ga) minimum ground wire into the slot in lug and tighten
the locknut securely. Connect the other end of the wire
to a true earth ground.

IG.9
Pressure Relief Procedure
1. Lock the gun/valve trigger.
2. For D200s, D200, S20, and D60 Air Controls: See
FIG. 3, page 12.
a. Close the air motor slider valve (BF) and the
main air slider valve (BA).
b. Set the ram director valve to DOWN. The ram
will slowly drop.
c. Jog the director valve (BC) up and down to
bleed air from ram cylinders.
3. For L20c Air Controls: See FIG. 7, page 14.
a. Close the air motor valve (DC) and the elevator
director valve (DD). The ram will slowly drop.
4. Unlock the gun/valve trigger.
Air hoses: use only electrically conductive hoses.
Fluid hoses: use only electrically conductive hoses.
Air compressor: follow manufacturer’s recommenda-
tions.
Spray gun/dispense valve: ground through connection
to a properly grounded fluid hose and pump.
Fluid supply container: follow local code.
Object being sprayed: follow local code.
All solvent pails used when flushing: follow local
code. Use only conductive metal pails placed on a
grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which
interrupts the grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure, always hold a metal part of the
gun/valve firmly to the side of a grounded metal pail,
then trigger the gun/valve.
5. 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.
6. Lock the gun/valve trigger.
7. Open the fluid line drain valve and the pump bleeder
valve (P). Have a container ready to catch the drainage.
8. Leave the pump bleeder valve (P) open until ready
to spray again.
If you suspect that the spray tip/nozzle or hose is completely 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.

Maintenance Procedures
Flush Before Using Equipment
The pump was tested with lightweight oil, which is left in
the fluid passages to protect parts. To avoid contaminating your fluid with oil, flush the pump with a compatible
solvent before use. See your pump manual for flushing
directions.
Maintenance Procedures
To reduce the risk of serious injury whenever you are
instructed to relieve pressure, always follow the
Pressure Relief procedure.
Platen Maintenance
See FIG. 10. If the platen does not come out of the pail
easily when the pump is being raised, the air assist tube
(F), or check valve may be plugged. A plugged valve
prevents air from reaching the underside of the plate to
assist in raising it from the pail.
Adjust Spacers
Use Platen with Tapered and Straight Sided
Pails
The platen is supplied for use with 20 liter (5 gallon), 30
liter (8 gallon), and 60 liter (16 gallon) straight sided
pails, but only single wiper platens can be easily modified for use with tapered pails.
Use platen with tapered pails
1. Working from the bottom, use screwdriver to pry
spacer (EG) loose. Work spacer upward completely
above the flange of the platen. See F
2. By hand, angle spacer (EG) and work it off the plate,
pulling it down over the flange and bottom wipers
(EB). See FIG. 12.
3. Save spacer (EG), as it is required for other applications.
IG. 11.
1. Relieve pressure. Refer to parts illustration on page
58 and disassemble air assist valve as shown.
2. Clear air assist tube (F) in platen. Clean all parts of
valve and reassemble.
3. Remove bleed stick (EK) from platen. Push bleed
stick through bleed relieve ports to remove material
residue.
