3.11 HITCH COUPLER & AXLE (CE ONLY)
To insure continuing reliability and road safety in traffic, the
maintenance tasks have to be performed at the prescribed
intervals. Maintenance, repairs, and replacement of wearing
parts for the chassis and the braking system may only per-
formed by a qualified garage.
Only original JLG parts may be used in order to:
• ensure proper functioning and safety
• preserve all rights under warranty
• prevent the operating license from becoming invalid under
national and international regulations.
Ball Coupler
The ball coupler is equipped with a safety check indicator. This
consists of clearly embossed symbols to which a red-green-red
label with the same symbols has been glued and an indicator
button. If the label is damaged, it can be removed and the
embossed symbols used, or the label can be replaced, in
which case the lines dividing the zones on the label and the
embossing must be aligned.
UNCOUPLING
To open, pull the coupling handle upwards and then turn it
forwards.
The coupling automatically remains in the open position, in
which the indicator button points to the red field with the
large X.
THE TRAILER MUST NEVER BE DRIVEN IN THIS POSITION.
NEVER INSERT YOUR FINGERS IN THE OPEN BALL COUPLER. EVEN SLIGHT
PRESSURE ON THE SPHERE CAN TRIGGER THE SPRING-LOAD CLOSING MECHA-
NISM AND RESULT IN INJURY TO THE FINGERS.
COUPLING
To couple the trailer, place the open ball coupler (X position)
on the ball of the towing vehicle so that it clicks into place
audibly.
When the ball coupler has clicked into place, the indicator
jumps to the green zone .
After coupling, it is essential to use the indicator to ensure that
the ball coupler has clicked into place on the ball correctly.
If the indicator is in the green + zone, the ball coupler is cor-
rectly closed and locked, and the ball on the vehicle still has
sufficient wearing reserves.
THERE IS NO SAFE CONNECTION BETWEEN THE TOWING VEHICLE AND THE
TRAILER UNLESS THIS HAS HAPPENED, AND THE VEHICLE COMBINATION
MUST NOT BE USED ON THE ROADS UNTIL THEN. DO NOT FORGET TO RELEASE
THE HANDBRAKE ON THE TRAILER, AND TO FIT THE SAFETY CABLE TO THE
BALL NECK.
The safety cable has the function of forcing the emergency
braking of the trailer if it should separate from the towing
vehicle for any reason.
