Gear shifting
Automatic Power
(APS II)
(Gear selector in speed gear
position 3 or 4)
The shift modulation allows the
machine operator to select different
automatic shifting programmes
(modes) depending on
operating conditions.

Operating in the APS position

• Turn the gear selector control to gear position 3 or 4.
• Set the shift mode selector within the automatic range (not the
manual).
• Select directional gear.
• Accelerate and the machine will start in 2nd gear (basic gear).
If the machine is already moving, it will engage 3rd gear
automatically.
• Up- and downshifts are made between 2nd - 3rd - 4th gears
forward and between 2nd - 3rd - 4th gear in reverse.
• When the direction of travel has been changed the machine will
start off in 2nd gear
• For shifting down to 1st gear. see "Kick-down function" on the
next page.

Position LIGHT

• The first position means that the gear shifting will take place at
low engine speeds and is preferably used for transport operations
without load.
• The second position means that the gear shifting will take place
at a slightly higher engine speed than in the first position and is
used for lighter loading-carrying operations.
• With the accelerator fully depressed, upshifting takes place
according to the HEAVY position.
• The best utilisation is obtained if the accelerator is not depressed
fully, as the difference in engine speed at which up-shifting takes
place between the LIGHT and HEAVY positions will be more
noticeable.
• Results in lower fuel consumption and lower noise level.

Position HEAVY

• The machine does not shift until higher engine and travelling
speeds have been reached.
• Preferably used in cases where the machine changes gear when
operating uphill or when the rolling resistance is great.
Position MAN (manual)
• After starting gear shifting is done manually, see page 74.
