9. Rub clean hydraulic fluid along the O-ring on
the bottom of the new filter.
10. Thread the new filter into the filter housing
and tighten by hand.
To inspect the hydraulic fluid:
1. Look at the color of the hydraulic fluid in the
sight window.
— If the fluid is milky in appearance, then
the hydraulic fluid is contaminated with
water. Repair leaks or fix the source of
the problem and perform a major ser-
vice.
— If the fluid is dark brown or opaque, then
the hydraulic fluid is severely contaminat
-
ed or thermal breakdown has occurred.
Correct the source of the contamination
or which component is causing thermal
breakdown, and perform a major service.
2. Smell the hydraulic fluid (remove breather
cap).
— If the fluid smells rancid or burnt, then ther
-
mal breakdown has most likely occurred.
Correct the component that is causing
thermal breakdown and perform a major
service.
The hydraulic tank, when filled correctly at the
sight window, holds approximately 13.5 gallons
of hydraulic fluid. Before draining the hydraulic
fluid, make sure you have a drain pan that will
hold that much fluid or make sure that you are
prepared to drain the tank, plug the tank, empty
your drain pan, drain the tank, and so forth.
To drain the hydraulic fluid:
1. Read and understand the hydraulic safety
instructions on Page
8!
2. Place your drain pan under the drain plug
(Figure 32) and remove the drain plug.

Hydraulic System
Major Service
The hydraulic system major service consists of
performing a complete “Minor Service,” draining
the old hydraulic fluid, cleaning the tank screen,
cleaning the tank, and adding new fluid.
The hydraulic system on this machine cre-
ates very high pressure and the hydraulic
fluid gets hot. Always stop the resaw, open
the conveyor speed valves, make sure the
pressure gauge reads 0 PSI, and make sure
the fluid cools down before removing any
lines or servicing the hydraulic system.
