Hydraulic System
Major Service
a major service consists of performing a “Minor
service,” plus draining the fluid, cleaning the tank
and screen, and filling the tank with new fluid.
The hydraulic fluid is hot and under high
pressure when the hydraulic pump motor is
running. Always stop the resaw, make sure
the pressure gauge reads 0 pSI, and make
sure the fluid is cool before servicing.
