Wacker Neuson Telehandler TH412 Operator's Manual page 245

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.
