Towing the machine requires bypassing the drive. In this
case the drivetrain is switched from power transmission to
freewheeling. For this purpose the variable displacement
pump is equipped with high-pressure limiting valves with
bypass function. The axial-piston variable displacement
pump can be accessed from the lower side of the
machine.
Before towing the machine
1. Unscrew the lower cover plate.
2. Loosen hexagon nuts 2 of the high-pressure limiting
valves.
3. Screw in threaded bolts 1 until they are flush with the
hexagon nuts.
➥ The machine can be towed.
Once towing is over:
1. Unscrew threaded bolts 1 as far as they will go.
2. Tighten hexagon nut 2 to 22 Nm torque.
3. Screw on the lower cover plate.
