9 - "HIGH FLOW" HYDRAULIC SYSTEM CONTROL
(3 LINES) (IF INSTALLED)
WARNING
q
Avoid connecting any equipment to the hydraulic lines
before said equipment has been correctly installed from
a mechanical point of view and secured to the machine
front coupling.
q
Avoid connecting any manually-controlled equipment or
tool (for example, hand hammer) to the hydraulic lines
while the equipment/tool is working.
q
Connect the hydraulic and electric lines only with the
engine off and the parking brake applied.
q
To avoid serious injury, always operate the equipment
while seated in driving position. Do not allow anyone to
get too close the machine or the equipment.
q
Read the contents of the equipment instruction manual
carefully before using the machine or carrying out main-
tenance operations.
IMPORTANT
q
When the HIGH FLOW hydraulic button (1) is pressed,
the flow conveyed to the hydraulic connections positio-
ned on the left side of the loader arm for the operation of
the equipment is higher than the standard flow.
DANGER
q
If the engine is running and the parking brake isn't ap-
plied, when the HIGH FLOW button (1) is pressed the
LED on the button comes on and the hydraulic oil flow
rate through the front auxiliary rapid couplings is high.
q
The HIGH FLOW hydraulic system can be operated only
with the equipment installed on the machine.
q
Press the HIGH FLOW button again to stop the increa-
sed hydraulic flow.
The "High Flow" to the equipment is bidirectional, is controlled
by the pedal (A) (see "3.3.5 pos. 4 - AUXILIARY HYDRAULIC
KIT CONTROL PEDAL (IF INSTALLED)") and is proportional to
the pressure exerted on the pedal in both directions. The
hydraulic and electric lines are positioned on the left side of
the loader arm.
