QUADRISHIFT II FUNCTION
Switch (1) is used to activate or de-activate the QUADRISHIFT II
function. Activation of the QUADRISHIFT function is displayed by
the warning light of switch (1) coming on. The QUADRISHIFT II
function selects the gear best suitable for the forward speed
when the driver changes gears.
SHIFTING ONE GEAR UP
When you change gears, a drop of the engine speed is generated
(figure 1). When towing a high load, it is necessary to decrease
the torque ratios when shifting gears up so as to maintain an
optimal engine speed to accelerate.
Action of QUADRISHIFT II:
In this case, the QUADRISHIFT II function automatically selects
the torque ratio when a gear shift occurs to avoid any
under-speed (figure 2).
SHIFTING ONE GEAR DOWN
When you change gears, an increase of the engine speed is
generated. It is then necessary to increase the torque ratios when
shifting gears down so as to avoid any engine over-speed.
Action of QUADRISHIFT II:
In this case, the QUADRISHIFT II function automatically selects
the torque ratio when a gear shift occurs to avoid any engine
over-speed.
