pressure & charging
Two accumulator tanks with gas charged pistons that
provide reserve hydraulic power and compensate
for normal pressure variations in the cutter and skip
cylinder hydraulic circuits are located near the high
pressure filters below the center deck access plate.
Required charge pressure is specific to each accumu
-
lator and is marked on the housing. Always make
sure to follow proper procedure to bleed pressure
from the accumulators and hydraulic circuits before
servicing the system.
Before performing any maintenance procedure,
make sure the cutting system is shutdown with
the truck in the service position.
