MAINTENANCE/SERVICE
HYDRAULICS
The windrower is hydraulically powered using:
1. A self-contained hydraulic system to operate
the header functions.
2. The tractor remote system to operate the
header lift cylinder and steering cylinder.
Hydraulic Hoses and Lines
Check hydraulic hoses and lines daily for signs of
leaks.
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: Keep hydraulic coupler tips and
connectors clean. Dust, dirt, water and foreign
material are the major causes of hydraulic system
damage. DO NOT attempt to service hydraulic
system in the field. Precision fits require WHITE
ROOM CARE during overhaul.
Hydraulic Reservoir
The windrower’s self-contained hydraulic system
uses the tongue of the machine for the hydraulic
oil reservoir. See “Recommended Fluids and
Lubricants” on page 40 for proper oil type and
capacity.
Check oil level daily (before start-up) at dipstick
(A) at rear of tongue. Oil level should be between
ADD and FULL marks on the dipstick when top
surface (C) of tongue is level and oil is cold.
WARNING: To avoid injury from
contact with hot oil, do not remove
dipstick when system is hot. When
removing dipstick (A), unscrew it slowly to
vent the build-up of air pressure in the
reservoir.
To add hydraulic oil:
1. Loosen hydraulic fitting (B) to vent reservoir,
making adding oil easier.
2. Slowly unscrew dipstick (A) from filler tube.
3. Add oil until level is between ADD and FULL
marks on dipstick (A). (See page 40 for oil
specs).
4. Replace dipstick and tighten fitting (B).
