Description of the loader Avant 860i
38
.
1 and 2 pump selection switch
Some attachments require high flow of hydraulic or
the attachment to work in the most effective way.
The loader is equipped with two auxiliary hydraulic
pumps. Both pumps are always running. With this
switch in the dashboard the output of both pumps
can be directed to the attachment, and to the boom
telescope function at the same time. If high flow is
needed, select the 2-pump setting.
Switch position:
1 PUMP
2 PUMP
1.
1 pump selected: one pump
coupled for auxiliary
hydraulics (lower oil flow).
Use this setting unless higher
hydraulic flow to the
attachment is required.
2.
2 pumps selected (higher oil
flow). Use this setting only
when the attachment requires
high flow of hydraulic oil.
See the operator’s manual of each attachment for
recommended and maximum oil flow levels.
If the attachment requires only low power to operate,
in some cases it can be useful to use the two-pump
setting while using low engine rpm. This reduces the
noise of the loader. If the attachment or loader stalls,
switch to 1-pump setting and increase engine rpm.
In normal use, keep the pump
selection switch at the 1-pump
setting to avoid overspeed of the
attachment and stalling of the
loader. Keeping the switch at the
2-pump setting unnecessarily will
decrease the efficiency of the
hydraulic system of the loader.
This switch will also affect the
speed of the telescopic function of
the boom.
WARNING
Risk of thrown objects,
increased noise and vibration,
and equipment damage - Check
the maximum oil flow of each
attachment.
Some attachments
may eject material at high speed
when operated too fast. Damaged
machine parts may also be
ejected. Too fast operation will
cause increased noise, vibration,
and wear. Check the operator's
manual of each attachment and
adjust the auxiliary hydraulics oil
flow accordingly. See page 37.
