7.12 HYDRAULIC SYSTEM
The M150 and M200 Windrower hydraulic system
provides oil for the windrower drive system, and
header lift and 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
Windrower Dealer for all other service.
7.12.1 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.
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 right cab-forward side platform to access
the filler pipe. Check level when oil is cold for most
accurate reading.
d. Turn filler cap counter clockwise to loosen bung,
and remove dipstick.
e. Maintain level between LOW and FULL marks. If
necessary, add SAE 15W40 Compliant with SAE
Specs for API Class SJ and CH-4 Engine Oil.
NOTE
LOW to FULL capacity is approximately 1
U.S. gallon (4 litres).
f. Reinstall filler cap, and turn clockwise to tighten
bung.
