Machine Operation
Operating the Auxiliary Hydraulics
Use the auxiliary hydraulics to operate a
breaker, angle bucket or other approved
attachments.
Two methods of operation are permitted:
operation with the auxiliary hydraulic buttons,
and operation with the slider switch.
Operating the Auxiliary Hydraulic
Switches
To deliver hydraulic oil to port (a):
Depress (A).
• When using a hydraulic breaker or other
one-way flow attachment.
To deliver hydraulic oil to port (b):
Depress (B).
When using a hydraulic breaker or other 1-
way flow attachment:
Change the direction of the hydraulic oil flow
by setting flow selector switch (C) ON to
return the oil in the (b) port line directly to the
hydraulic tank.
Refer to page 56, “Flow Selector Switch.”
When using detent mode switch (D):
IMPORTANT: Operation over long periods
with Detent mode switch pressed will
cause the hydraulic oil temperature to rise
and will shorten the life of the hydraulic
units.
Pressing the detent mode switch (D) lights
the orange lamp and the auxiliary hydraulic
switch (A) changes to detent mode.
Detent mode
One press of the auxiliary hydraulic switch (A)
sets it to ON, and one more press sets it to
OFF. There is no need to continue pressing
the switch.
Refer to page 57, “Detent Mode Switch.”
Operating the High-Flow Hydraulics
Refer to page 63, “High-Flow Hydraulic
System.”
