Manual gearbox
9.1 GENERAL
To prevent rapid wear and burning of the clutch plate and clutch release
assembly, only use first gear when driving off. This applies to both a laden and
an unladen vehicle.
Always depress the clutch fully when changing gear to prevent excessive wear
of the synchromesh units.
The gearboxes are synchromesh units. When changing gear, exert consistently steady
pressure on the gear change lever until the gear has engaged.
CAUTION: Shifting down at a speed that is too high for the selected
gear can damage the engine (overspeeding) and/or the gearbox.
– When shifting down, make sure that the speed is not too high for
the selected gear.
CAUTION: Engaging a drive-off gear while the vehicle is moving can
damage the gearbox and differential.
– Only engage the forward drive-off gear when the vehicle is fully
stationary, the engine is at idle speed and the clutch is fully
pressed.
– Only engage the reverse gear 3 seconds after the vehicle is fully
stationary, the engine is at idle speed and the clutch is fully
pressed.
– Do not drive off in the opposite direction while the vehicle is still
moving.
9.2 CHANGING GEAR WITH THE 16-SPEED GEARBOX
The main gearbox has four gearbox
ratios, which must be selected twice, in
two speed ranges. A low speed range
(1
st
to 4
th
gear) and a high speed range
(5
th
to 8
th
gear). The splitter box can
split every speed, giving a total of 16
speeds (splitting).
