INSpecTIoN (fIg. 19)
Inspect all parts of the filter assembly before reassembly.
1. Inspect the ball inside the filter element. If the ball has
pressure cuts or scratches, replace the filter element.
a. If the ball is cut, remove the PTFE o-ring (5) using an
o-ring pick and remove the carbide seat (6).
b. Check the seat for nicks or grooves. If the seat is
damaged, replace.
Removal of the PTFE o-ring will damage the
i
o-ring and require replacement.
2. Remove the spring (2) from the spring guide on the filter
cap.
a. Measure the length of the spring uncompressed. If it
measures less than 3/4" from end to end, replace.
b. Push the spring back onto the spring guide until it
"snaps" back into position.
3. Inspect the two PTFE gaskets (7,8) and the PTFE o-ring (5)
for deformity, nicks, or cuts. Replace, if needed.
The PTFE gaskets, PTFE o-ring, and spring are
i
packaged in Filter Service Kit P/N 930-050.
reASSemBly (fIg. 19)
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).
The top and bottom of the filter element with
i
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 ProMark hydraulic system. Do
not use any other hydraulic fluid. Use of any
Attention
other hydraulic fluid may seriously damage the
hydraulic system and will void the warranty.
1. Check the hydraulic fluid daily. It should be at the "Full"
mark on the dipstick.
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
Attention
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 during a fluid
i
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.
