For the retract position, the lever (1) should be moved
away from the operator one position. An adjustable
pressure detent will hold the control lever in this
position until the cylinder reaches the end of its travel,
then release to the neutral position. To prevent over-
travel into the float position, the lockout lever can be
moved to the first (center) position.
IMPORTANT: Do not manually restrain a lever to
override the detent release for continuous operation or
excessive noise and detent damage may occur.
The float position (2) is the position farthest away
from the operator, two detents from neutral.
The float position will be locked out when the lockout
lever is in the first detent and the control lever is
in neutral. Once in the retract or float position, the
lockout lever can be moved to the second detent to
prevent the lever from moving back into the neutral
position for motor operation.
The float position is generally used for implements
that are designed to “float” over the ground during
normal operation. When the remote valve is in the
float position, hydraulic oil on the rod end and piston
end of a cylinder can flow freely from one side of the
cylinder to the other.
Lockout Levers
Below each control lever is a corresponding lockout
lever to prevent or limit travel of the control lever. The
lockout lever has three positions.
The rearward position (3) (closest to the operator)
releases the lock and allows full travel to all control
lever positions.
