Safety Instructions For Maintenance; Operating Instructions; Coupling - Holland GES20 Bedienung-Wartung

• The corresponding safety provisions must be ad-
hered to when coupling, for example those of the li-
ability insurance associations in Germany. Only carry
out the coupling process on an even base with suffi-
cient load-bearing capacity
• The semitrailer plate must be preferably the same
height or maximum 50 mm lower than the fifth
wheel plate during coupling. The height of the semi-
trailer can change through pressure losses in the
pneumatic suspension
• Check the locking mechanism for correct locking
before driving off. Only drive with the locking mecha-
nism securely locked into place
• Recommended area of application: 2-axle tractor on
surfaced roads (no off-road operation)
• Use with semitrailers corresponding to ISO 1726 and
ISO 1726 Part 2, whose trailer plate is sufficiently
rigid and even. Maximum permissible unevenness of
the semitrailer plate:
3 mm in a loaded state
2 mm in an unloaded state

anism! (see page 37)

unlocking handle must be fully pulled out
• The locking mechanism is in the opened position
• The semitrailer plate must be 2 cm to max. 5 cm
lower than the fifth wheel plate
• Step out from between the vehicles
• Slowly reverse the tractor under the semitrailer
