Brake lining wear equalisation

If the brake linings on one axle wear faster than on the
others, the braking force is altered to equalize the
wear.
A symbol is shown on the display when there is less
than 20% of the lining left.

Panic braking function

If the brake pedal is depressed very quickly, the brake
pressure is rapidly increased and the braking effect is
more powerful. The function is provided to reach full
braking force more quickly in emergency situations.

Manual gearbox

General
Starting always start in 1st gear or crawler gear with
as low engine speed as possible (700–800 rpm). Do
not slip the clutch. Select the next gear as soon as the
truck is rolling. Let the engine work within it's most
efficient range, the lower part of the tachometer's
green field. Only use full power when you really need
it. Drive according to the tachometer, not the
engine sound!
Reverse gear
The reverse gear is unsynchronised. Shift to LOW
range before engaging reverse. In good driving
conditions it is possible to reverse with HIGH range
engaged.
To get into reverse gear more easily, engage a
synchronised gear before the reverse gear. This stops
the gearbox shafts from rotating and the engagement
teeth are not worn so much.
Symbol on the display when there is
less than 20% of the brake lining
left.
Note!
It is not permitted to shift between
HIGH and LOW range while
reversing. First shift to HIGH or
LOW range, then engage reverse.
