Hydraulics
The float module frame acts as an oil reservoir. Refer to the inside back cover for information on the float module
’
s oil
requirements.
4.4.1
Checking Oil Level in Hydraulic Reservoir
The oil level in the header
’
s hydraulic oil reservoir can be inspected via the sight glass on the float module.
DANGER
To prevent injury or death from the unexpected start-up of the machine, always stop the engine and remove the key
from the ignition before leaving the operator
’
s seat for any reason.
NOTE:
The hydraulic oil level should be inspected when the hydraulic oil is cold.
1.
Start the engine.
2.
Lower the header to the ground.
3.
Fully retract the center-link.
4.
Shut down the engine, and remove the key from the ignition.

Ensure that the oil is at the appropriate level for the terrain
as follows:
•
Level terrain (1):
Lower sight (A) should be full and
upper sight (B) should be empty.
•
Sloped terrain (2):
Lower sight (A) should be full and
upper sight (B) should be, at most, half-full.
NOTE:
It may be necessary to slightly reduce the oil level when the
ambient temperatures exceeds 5°C (95°F); this will prevent
overflow at the breather tube.
NOTE:
The sloped terrain oil level specification can be referred to
even when the header is being operated in level terrain, as
long as the Filler Neck Extension kit (B6057) is installed.
4.4.2
Adding Oil to Hydraulic Reservoir
If the oil level in the hydraulic reservoir is low, or if the oil has been drained, oil will need to be added.
DANGER
To prevent injury or death from the unexpected start-up of the machine, always stop the engine and remove the key
from the ignition before leaving the operator
’
s seat for any reason.
1.
Shut down the engine, and remove the key from the ignition.
