Drain & Flush the hydraulic tank:
1. Make sure the hydraulic system is not pres-
surized and the fluid is cool.
2. Drain the tank into a suitable container by
removing drain plug at the bottom of the tank.
3. When the tank is drained, loosen the bolts
securing the inspection plates and remove the
plates. Use a bright light to inspect for sludge
buildup and other contamination.
4. Remove sludge and contaminates, then flush
the tank until it is clean using fresh hydraulic
fluid.
5. Coat the seals with hydraulic fluid and install
the plates. Tighten the bolts to secure the
plate.
6. Install the drain plug.
7.

Replacing The Hydraulic Filter
Before performing any maintenance procedure,
make sure the paint system is shutdown with the
truck in the service position.
The filter is the spin on type filters located in the
return line near the top of the hydraulic reservoir.
A pressure gauge on the filter housing indicates
when the filter requires changing.
Changing the filter:
1. Make sure the hydraulic system is not pressur-
ized and the fluid is cool. Use a filter wrench
and rotate the filter counterclockwise to re -
move it.
2. Lubricate the seal on the new filter with hy -
draulic fluid.
3. Install the filter and hand tighten.
4. Inspect the filter for leaks when the hydraulic
system is activated.
