Operating instructions
Drive speed range selection switch
Avant 530 is equipped with two-speed hydraulic drive
motors. Drive speed range can be selected with the switch
on the control panel right (see page 14). In addition to
speed, the speed range switch affects the pulling force as
shown in table.
Higher speed range is intended for longer travels where
high pulling force is not necessary.
Do not change the drive speed range while
driving with a higher speed. Always stop the
machine first or slow down the speed before
switching on higher or lower speed. Be careful
when driving at higher speed range. Do not
turn the steering wheel quickly at high travel
speed.
Parking brake switch
Avant 520/528/530 is equipped with a hydraulic parking
brake. Parking brake is operated with the switch on the
control panel right (see page 14). On cab LX/DLX the
switch is located in the panel up right.
• A red indicator on the switch lights up
when parking brake is engaged.
• The green backlight under the “P” is lit all
the time.
Parking brake engages automatically when the engine is
stopped. The brake can be released only when the engine
is running and there is hydraulic pressure in the system.
Do not engage the parking brake when the
machine is moving unless in emergency. Using
the brake while moving may cause the locking
of wheels and sudden stopping of the machine.
If the parking brake is engaged repeatedly
when the machine is moving the brake plates
in the drive motors will get worn quickly.
Always stop the machine before engaging the
brake.
Seat heater
The suspension seat is equipped
with an electric seat heater. Seat
heater switch (15) and indicator
are located on the dashboard.
Smooth drive (option)
Avant 530 can be equipped, as
an option, with the smooth drive
which is a shock absorber system
for the boom. When driving at high
speed with a heavy load or heavy
attachment, the boom starts to
move up and down, making driving
unpleasant. The smooth drive
consists of an accumulator which
absorbs and eliminates boom
movements and makes driving considerably smoother and
more stable. Smooth drive is switched on with the boom
floating switch no. 17.
NOTICE: The machine must also be equipped with both
boom self levelling and boom floating.
Switch on the smooth drive only when
stationary and when the load is close to the
ground to avoid change in stability caused
by possible movement of the boom when
switching on. Keep the smooth drive off when
loading or lifting with the loader.
Boom self levelling (option)
Self levelling system keeps the position
of the attachment the same in relation
to the ground, regardless of the position
of the boom.
Self levelling is hydraulic: there is a
levelling cylinder on the left side of the
boom which follows the movements
of the bucket tilt cylinder and keeps
the attachment level. Self levelling is
disabled when the boom floating is switched on.
