9.Rub clean hydraulic fluid along the
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.

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.
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.
