COLOR CHANGE / CLEAN OUT
CAUTION:
USE ONLY COMPATIBLE SOLVENTS WHEN CLEAN-
ING OUT OIL BASED ENAMELS, LACQUERS, COAL TAR, AND
EPOXIES. CHECK WITH THE FLUID MANUFACTURER FOR A
RECOMMENDED SOLVENT.
1. Reduce pressure by turning the Pressure Adjustment Knob and
the Pressure Bleed Valve on the bleed line counterclockwise.
Follow the Pressure Relief Procedure above. The Pressure Bleed
Valve should be turned counterclockwise at least three full turns.
2. Pull syphon tube out of material container.
3. Remove spray tip from gun. Hold gun trigger open until material
flow stops.
4. Put syphon tube into wash solvent or water as applicable, and
operate pump slowly at low pressure until solvent flows freely from
Pressure Bleed valve line.
5. Close Pressure Bleed Valve and hold gun trigger open until sol-
vent flows freely from gun. If solvent is not too dirty, recirculate it by
flowing gun stream back into solvent container. Use additional
clean solvent and repeat procedure if necessary.
6. Check gun strainer screen and pump outlet filter screen daily.
Use 50 mesh screens with spray tip size .018 and larger. Use 100
or 200 mesh screens with spray tip sizes .015 and smaller.
7. Replace paint filter cap to maximum clockwise rotation. The fil-
ter cover should be hand removable after the first or second use
with new
37)(
O-Ring. IMPORTANT: O-Ring must have
37)(
backup washer to seal properly.
8. If unit has been spraying a water soluble material, flush with
water and then repeat procedure with mineral spirits or Varsol
solvent.
9. Wash spray tip in solvent. Blow tip clean with air pressure
directed through the tip in the reverse direction.
MAINTENANCE
HYDRAULIC SYSTEM
IMPORTANT INFORMATION:
Use of Titan/Speeflo's Coolflo™
Hydraulic Fluid is mandatory in the PowrTwin 3500™ hydraulic
system. Do not use any other hydraulic fluid. Use of any other
hydraulic fluid will seriously damage hydraulic system and
void warranty.
1. Check the hydraulic fluid daily. It should read "Full" on the dip-
stick. If it is low, add only Titan/Speeflo Coolflo™ Hydraulic Fluid,
Part # 430-361. Never add or change hydraulic fluid except in a
clean dust free area. Contamination of the hydraulic fluid will short-
en Hydraulic pump life and may void warranty.
2. Change the hydraulic fluid every six months. Drain old fluid from
tank and fill with 5 quarts of Titan/Speeflo Coolflo™ Hydraulic
Fluid. Start operation of the system at just enough pressure to
operate the fluid pump. Run the system at this low pressure for at
least 5 minutes. This removes air from the system. Check the fluid
level after this procedure.
3. The Hydraulic System has an external replaceable Hydraulic
Filter. Change the filter every six months.
4. The Hydraulic Pump should not be serviced in the field. If ser-
vice on the Hydraulic Pump is required, it must be returned to
Titan/Speeflo.
GENERAL FLUID PUMP MAINTENANCE
If the paint pump is going to be out of service for an extended peri-
od of time, it is recommended that following cleanup a kerosene
and oil mixture be introduced as a preservative. Packings may tend
to dry out from lack of use. This is particularly true of the upper
packing set for which upper packing lubricant, Piston Lube,
Titan/Speeflo Part # 700-925, is recommended in normal usage. A
sample of Lubrisolv accompanies each new unit. Do not substitute
water or paint solvent for Lubrisolv. Ordinary oil may contaminate
the paint material and is not recommended.
If the paint pump has been out of service for an extended peri-
od of time, it may be necessary to prime the suction by pouring
some of the paint solvent into the inlet syphon tube to restart. It is
extremely important that the threads on the inlet syphon hose cou-
pling are properly sealed. Any air leakage will produce erratic oper-
ation of pump and may damage the system. The up and the down
strokes should be approximately equal in time. That is, one should
not be faster than the other. A fast up or down stroke may indicate
air in the system or malfunctioning valve or seats. See the
Troubleshooting Guide.
