MAINTENANCE/SERVICE
Hydraulic System
WARNING: Avoid high pressure
fluids. Escaping fluid can penetrate
the skin causing serious injury.
Relieve pressure before
disconnecting hydraulic lines. Tighten all
connections before applying pressure. Keep
hands and body away from pin-holes and
nozzles which eject fluids under high pressure.
Use a piece of cardboard or paper to search for
leaks. If ANY fluid is injected into the skin, it
must be surgically removed within a few hours
by a doctor familiar with this type of injury or
gangrene may result.
IMPORTANT: Dirt, dust, water and foreign
material are the major causes of trouble
developing in the hydraulic system. If the hydraulic
system should be disconnected for service, protect
the ends of hoses, tubing and ports of components
from contamination with clean, lint-free towels or
clean plastic bags. Before installing any
replacement hose, flush the inside of it with
unused diesel fuel or unused commercial
petroleum cleaning solvent for ten seconds
minimum. Do not use water, water soluble
cleaners or compressed air.
IMPORTANT: The components in this system are
built to very close tolerances and have been
adjusted at the factory. Do not attempt to service
these components except to maintain proper oil
level, change oil and filters and to adjust relief
pressures as described in this manual. See your
Windrower Dealer for all other service.
