57.9 HYDRAULIC SYSTEM
The M100 Windrower hydraulic system provides
oil for the windrower drive system, and header
lift and drive systems.
Hydraulic schematics are placed at the back of
this manual.
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.
57.9.1 Oil Level
Check hydraulic oil level when oil is cold for
most accurate reading:
DANGER
Stop engine and remove key from ignition
before leaving operator's seat for any
reason. A child or even a pet could engage
an idling machine.
IMPORTANT
To prevent damage to the lift system when
lowering header lift linkages without a
header or weight box attached to
windrower, ensure that float engagement
pin is installed in storage location (A), and
not installed at hole location (B).
a. Park windrower on level ground and lower
header and reel so that lift cylinders are fully
retracted.
b. Stop engine and remove key.
c. Stand on platform to access the filler pipe.
d. Turn filler cap counterclockwise to loosen bung,
and remove dipstick.
