Auxiliary Hydraulic System

Auxiliary hydraulics are used with attachments that have a mechanism requiring
hydraulic power.
Note: When ignition power is interrupted, auxiliary hydraulic function (both
standard and high-flow) are reset to OFF.

Standard-Flow Auxiliary Hydraulic Control

Loaders are equipped with a standard-flow auxiliary hydraulic system with flat-
face couplers. The couplers are located on top or inside of the lift arm on the left
side.
Loaders Equipped with Electric Auxiliary:
The black rocker switch located on the
right-hand control controls the direction
and amount of flow. The farther the switch
is moved from center, the higher the flow to
the auxiliary circuit. The direction of flow
is reversed when the rocker switch is
moved in the opposite direction from the
center. Pushing the switch to the right (or
up on T-bar controls) will pressurize the
standard auxiliary male coupler. For con-

either direction and push the trigger button,
located on the front of the grip for five sec-
onds, and release. To cancel continuous
operation, push the button or move the black switch in either direction.
High-Flow Auxiliary Hydraulic Control (Optional)
In addition to a standard-flow auxiliary
hydraulic system, loaders may be
equipped with a reversible high-flow aux-
iliary hydraulic system. The couplers are
located on top or inside of the right lift
arm. The high-flow auxiliary hydraulic
system is used for operating certain
hydraulic attachments (e.g., cold planer,
snowblower) that require higher flows.

the direction of hydraulic oil flow. The
switch is located on the upper left side
instrument panel. Push the right side of
the rocker switch for forward flow, or the left side for reverse flow. Pushing the
switch to the right will pressurize the high-flow male coupler. To disengage, push
and release either side of the switch. Turning off the machine, raising the restraint
bar, or restarting the engine will also reset the high-flow to neutral. A lamp on
