18/19 - BACKHOE CONTROL LEVERS
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 manoeuvre, 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, shifts the
reverse 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 controls and
raise both joysticks towards the rear of the machine.
q
Before starting work, check the control pattern by carrying
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 device
(A) to lock the controls (LED on).
The machine equipped with backhoe servo controls is particularly
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 operations.
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").
