CHANGING THE HYDRAULIC FLUID
Change the hydraulic fluid every twelve months.
i
The hydraulic system has an external, replaceable
hydraulic filter. Change the filter every twelve
months.
1. Put a container (enough to hold 6 gallons) directly
underneath the hydraulic tank drain plug.
2. Using a wrench, remove the drain plug from the hydraulic
tank. Allow the hydraulic fluid to fully drain from the tank.
Replace the drain plug.
3. Loosen and remove the filter housing (2) to expose the
filter. Twist the filter (3) counterclockwise and remove.
4. Fill the hydraulic tank with new hydraulic oil until the oil is
between the two notches on the dipstick.
5. Replace the filter (3) and filter housing (2).
When replacing the hydraulic filter (fig. 16, item
i
3) during a fluid change, it may be necessary to
add up to one additional quart of hydraulic fluid.
6. 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.
7. The hydraulic pump should not be serviced in the field.
If service on the hydraulic pump is required, it must be
returned to an authorized Titan Service Center.

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 coupling on the siphon tube is
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).

HIGH-PRESSURE HOSE
Inspect the high-pressure hose visually for any notches or
bulges, in particular at the transition in the fittings. It must be
possible to turn the union nuts freely. A conductivity of less
than 1 MΩ must exist across the entire length.
Have all the electric tests carried out by an
Authorized Titan Service Center.
Attention
The risk of damage rises with the age of the high-
i
pressure hose.
Titan recommends replacing high-pressure
hoses after 6 years.
