Float will permit the cylinder to extend or retract
allowing equipment such as scraper blades to “float”
or follow the ground contour .
The “float” position is also used for retracting a single-
acting cylinder and for the OFF position for hydraulic
motors .
NOTE: Do not hold the lever in the fully extend or
retracted position after a remote cylinder has reached the
end of its stroke. Doing so will overheat the oil and may
lead to failure of hydraulic pump driveline components.
Engagement Switch
The control levers and remote valves will operate only
when the system is activated by the EHR engagement
switch . To activate the EHR system, depress the center
button (7) in the engagement knob (8) and pull the
knob up until it stops, then release the center button
and knob . The EHR system is operational whenever
the engine is running .
To turn off the remote electro-hydraulics, depress the
engagement switch knob (8) as shown .
IMPORTANT: The remote valve EHR engagement
switch is provided as an isolator stop switch. It can be
used to immediately stop operation of the rear remote
hydraulics by quickly depressing the knob. The stop
switch only controls the remote valves and has no
effect on the three point hitch link operation, thereby
isolating operation of the rear remote hydraulics from
the three point hitch link operation.
