4.4.3 UNLOADING THE TRAILER

Tractor and trailer must be placed to drive forwards.

Ensure enough space for unloading.

Remove ramps' interlocks, lower the ramps to the ground.

Switch off tractor engine, secure the cab to prevent unauthorised access.

Remove all load fastening devices.

Unload the trailer using overhead crane, hoisting crane or another tractor.

IMPORTANT!

Lower the ramps until they fully rest on the ground. Otherwise, when a machine is driven
off the load platform, the trailer will have a tendency to raise the drawbar, which may
cause damage to the tractor hitch or drawbar.

If unloading takes place on soft ground, place planks, plates or other materials under the
ramps to prevent them from sinking into the ground.

4.5

RAMPS' PROTECTIONS

4.5.1 RAMPS' INTERLOCK

IMPORTANT!

If ramps' interlocks are installed on pins, position of ramps must not be adjusted (pins or
interlocks may get damaged).

Dismounting the interlock

Move the lock (3) of double ended bolt.

Unfold lever.

Part the lugs of bolt (4) by turning nut (2) with a lever.

Dismount the interlock.
