Reassembly (Fig. 17)
After cleaning and inspecting all parts, reassemble the filter.
1. Place the carbide seat (6) into the filter body (4). Make sure
the beveled side of the seat is facing up.
2. Place the PTFE o-ring (5) into the groove on the outer
diameter of the carbide seat (6).
3. Place the filter element with ball (3) into the filter body (4).
i
The top and bottom of the filter element with ball
are identical.
4. Push the spring (2) back onto the spring guide of the filter cap
(1) until it "snaps" back into position, if not already done.
5. Place the thin PTFE gasket (8) onto the step at the top of the
filter body (4).
6. Place the thick PTFE gasket (7) onto the top of the thin gasket
(8).
7. Tighten the filter cap assembly (1) onto the filter body (4).

Maintaining the Hydraulic System

Use of Titan's Coolflo™ Hydraulic Fluid is mandatory
in the PowrLiner hydraulic system. Do not use any
other hydraulic fluid. Use of any other hydraulic
fluid may seriously damage the hydraulic system
Attention
and will void the warranty.
1. Check the hydraulic fluid daily. It should be at the "Full"
mark (fig. 18, item 1) on the dipstick (2). If it is low, add only
Titan Coolflo™ Hydraulic Fluid (P/N 430-361). Never add
or change hydraulic fluid except in a clean, dust-free area.
Contamination of the hydraulic fluid will shorten hydraulic
pump life and may void warranty.
2. Change the hydraulic fluid every twelve months. Drain the
old fluid from the tank and fill with 6.25 quarts of hydraulic
fluid. Start the sprayer at just enough pressure to operate the
fluid section. Run the sprayer at this low pressure for at least
5 minutes. This removes air from the system. Check the fluid
level after this procedure. Do not over-fill.
When replacing the hydraulic filter (3) during a
i
fluid change, it may be necessary to add up to one
additional quart of hydraulic fluid.
3. The hydraulic system has an external, replaceable hydraulic
filter. Change the filter every twelve months.
4. The hydraulic pump should not be serviced in the field. If
service on the hydraulic pump is required, it must be returned
to Titan.

Maintaining the Fluid Section

If the sprayer is going to be out of service for an extended period 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 (P/N 314-480) is
recommended in normal usage.
If the sprayer has been out of service for an extended period of time,
it may be necessary to prime the pump with solvent. It is extremely
important that the threads on the siphon hose coupling are properly
sealed. Any air leakage will produce erratic operation of the sprayer
and may damage the system. The up and the down strokes should
be approximately equal in time (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 section).
6.5 Basic Engine Maintenance (gas engine)
• For detailed engine maintenance and technical specifications
refer to the separate gasoline engine manual.
• All service to the engine should be performed by a dealer
authorized by the engine manufacturer.
• Use a premium quality motor oil. 10W30 is recommended for
general all temperature use. Other viscosities may be required
in other climates.
• Use only a (NGK) BP6ES / BPR6E spark plug. Gap the plug
to 0.028 to 0.031 In. (0.7 to 0.8 mm) Always use a spark plug
wrench.
Daily
1. Check engine oil level, and fill as necessary.
2. Check gasoline level, and fill as necessary.
Always follow the fueling procedure outlined earlier
in this manual.
First 20 Hours
1. Change engine oil.
Every 100 Hours
1. Change engine oil.
2. Clean the sediment cup.
3. Clean and re-gap the spark plug.
4. Clean the spark arrestor.
Weekly
1. Remove the air filter cover and clean the element. In very
dusty environments, check the filter daily. Replace the
element as needed. Replacement elements can be purchased
from your local engine manufacturer dealer.
Engine Operation and Service
1. Clean and oil air filter pad on gasoline engine every 25 hours
or once weekly. Do not permit the air intake screen around
the fly wheel of the gas engine to load up with paint or
trash. Clean it regularly. The service life and efficiency of
the gas engine model depends upon keeping the gasoline
engine running properly. Change the oil in the engine
every 100 hours. Failure to observe this may result in engine
overheating. Consult the engine manufacturer's service
manual provided.
2. To conserve fuel, service life, and efficiency of the sprayer,
always operate the gasoline engine at the lowest RPM at
which it runs smoothly without laboring and delivers the
amount required for the particular painting operation.
Higher RPM does not produce higher working pressure. The
gasoline engine is connected to the hydraulic pump by a
pulley combination designed to produce full paint delivery at
maximum RPM.
3. The warranty on gasoline engines or electric motors is limited
to the original manufacturer.
