7.11 HYDRAULIC SYSTEM
The M105 Windrower hydraulic system provides
oil for the windrower drive system, the header
lift, and the drive systems.
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 Dealer
for all other service.
7.11.1 OIL LEVEL
Check hydraulic oil level daily as follows:
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 left front side platform to access the
filler pipe.
d. Turn filler cap counterclockwise to loosen bung,
and remove dipstick.
