18/19 - BACKHOE CONTROL LEVERS
(version with servo controls)
WARNING
q
Before carrying out any manoeuvre with these levers,
the operator must be seated in working position, that is,
with the seat rotated by 180° with respect to the driving
position and with fastened safety belt; before any ma-
noeuvre, take all the precautions specified in section
"3.13 USING THE MACHINE AS AN EXCAVATOR".
q
The machine is equipped with an acoustic alarm that is
activated if the operator, with the engine running, moves
the reversing gear lever (1) to position F or R with the
seat rotated in any position different from the correct
driving position.
This is a danger signal, since it is absolutely forbidden
to move the machine while working with the backhoe
equipment or in any case with the seat rotated by 180°
with respect to the regular driving position. Remember
that the operator is allowed to move the machine only
while seated in the correct driving position, with locked
seat and fastened safety belt.
q
Before leaving the driver’s seat, lower the equipment to
the ground, engage the safety device to lock the con-
trols and raise both joysticks towards the rear of the
machine.
q
Before starting work, check the control pattern by carry-
ing out short manoeuvres in order to make sure the all
the movements corresponds to those shown on the
plates.
q
When travelling on roads, always engage the safety de-
vice (A) to lock the controls (LED on).
The machine equipped with backhoe servo controls is particu-
larly useful, in fact less effort is required to shift the controls
and this reduces the stress to which the operator is subjected,
as well as the time required to carry out the various opera-
tions.
IMPORTANT
q
All movements are inhibited when the safety button (A)
is in locking position (LED on) (see "3.3.2 pos. 12 -
SERVO CONTROL LOCKING BUTTON").
