Drive speed range selection switch
Avant 760i is equipped with
two-speed hydraulic drive
motors. Drive speed range
can be selected with the
switch on the control panel
right (See page ). In addition
to speed, the speed range
switch affects the pulling force
as shown in table below.
Speed range switch
Speed range with
standard tyres
0-15 km/h 0-30 km/h
Pulling force, forward 100 % 50 %
Pulling force, reverse 100 % 50 %
Higher speed range is intended for longer travels
where high pulling force is not necessary.
CAUTION
Risk of abrupt movement - 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.
CAUTION
Risk of loss of control - Be
careful when driving at higher
speed range. Abrupt control
movements can cause the loader
to roll over. Do not turn the
steering wheel quickly when you
drive at high travel speed. Drive
slowly whenever carrying loads,
driving on inclined or rough terrain,
or on slippery surfaces. Always
reduce speed before sharp turns.
OptiDrive®
The 755 / 760 loaders are equipped with the efficient
Avant OptiDrive
®
hydraulic drive system as standard.
The system is designed for optimal hydraulic oil flow,
which helps to conserve energy by minimising
losses. This is achieved with the use of integrated
high efficiency Avant valve blocks and EO3 type
hose fittings.
.
When you want to have a high pulling force:
1.
Choose low speed range (760i)
2.
Use high engine rpm
3.
Press the drive pedal only lightly to select slow
drive speed. This way the full output of the
hydraulic system and the engine can be used
for high pulling force.
If the engine is overloaded while pushing, the
pedal shouldn't be pressed further. Instead, use
higher engine revs and push the pedal only a
little.
