3.4 Engaging the PTOs
3.4.1 Clutch-dependent PTOs
The PTOs can be operated with the vehicle standing or driving.
• Only switch the PTO on and off with the vehicle standing
still.
• Fully depress the clutch pedal at engine idle speed.
• Switch on PTO.
• Engage clutch slowly and move to operating speed.
NOTE
• Grating noises when activating the PTO are not permissible.
• Only engage PTO once the countershaft has come to a
complete stop. If the countershaft is not standing still, there
will be grating noises when engaging the PTO.
• Runout times differ depending on the operating mode and
may be reduced by short, initial synchronization of 1st gear.
If required, wait longer before actuation.
CAUTION
• Gear changes are not permissible when operating the PTO.
• Always switch off the PTO when you park the vehicle for a
longer time (e.g. overnight).
Gear interlock (option)
A gear interlock is required:
• when the vehicle must not be moved in any case while the
PTO is activated.
• when the PTO must not be activated while driving. For this
reason, a pneumatic ZF gear interlock system is available
for all clutch-dependent PTOs which protects the vehicle
against operating mistakes. The system is activated auto-
matically.
