a clean hydraulic system. Use only new
hydraulic fluid when filling reservoir.
Hydraulics
Refer to Section 1 regarding hydraulic safety. In addition:
• Inspect hydraulic system for leaks, damaged hoses
and loose ttings.
• Damaged hoses and hydraulic tubing can only
be repaired by replacement. DO NOT ATTEMPT
REPAIRS WITH TAPE OR CEMENTS. High
pressure will burst such repairs and cause system
failure and possible injury.
• Always place “Operating” valve into service position
and relieve hydraulic pressure from the system
before performing maintenance or repairs.
Note: Accumulator can store pressure even when
disconnected from tractor.
• Leaking cylinders - install a new seal kit.
• Fittings - use liquid Teon on all NPT hydraulic joints.
Do not use liquid Teon or Teon tape on JIC or
ORB ends.
• Hydraulic Hose Connections - when connecting the
hoses to the cylinders, tubing, etc. always use one
wrench to keep the hose from twisting and another
wrench to tighten the union. Excessive twisting will
shorten hose life.
• Keep ttings and couplers clean.
• Check the Tractor Manual for proper lter replacement
schedule.
Refer to the Trouble Shooting Section.
Caution
Dirt in the hydraulic system could damage
O-rings, causing leakage, pressure loss and
total system failure.
Warning
HIGH-PRESSURE FLUID HAZARD
To prevent serious injury or death:
• Relieve pressure on hydraulic system before servicing or
disconnecting hoses.
• Wear proper hand and eye protection when searching for
leaks. Use wood or cardboard instead of hands.
• Keep all components in good repair.
