9.2. Always use a recognised coupling bolt, along with a safety pin for the drawbar’s coupling eye, to be
coupled to the tractor’s coupler.
9.3. Keep in mind the type of ground that you’re driving on, and adjust the load of your trailer or semi-
trailer;
9.4. Distribute the load uniformly over the loading area of the trailer/semi-trailer and do not overload the
vehicle;
9.5. Do not drive or tip the trailer on sloping and/or unstable ground. Driving should be adapted to the
corresponding terrain and the ground conditions.
9.6. Do not force the hydraulic tipping cylinder to the end of its travel, and do not make sharp movements;
9.7. Make sure that the tractor is aligned with the trailer before tipping;
9.8. Do not allow people to stand next to the trailer/semi-trailer when tipping or reversing;
9.9. Keep clear of the trailer / semi-trailer when tipping or tipped;
9.10. Do not move the tractor while the box is tipped;
9.11. When tipping to the side, never fully open the hydraulic tipping cylinder;
9.12. If your TRAILER/SEMI-TRAILER is fitted with a “Hydraulic Rear Door”, disconnect the respective
hydraulic hoses before commencing side tipping, to prevent damage and accidents.
9.13. If your TRAILER/SEMI-TRAILER is fitted with a “Hydraulic Rear Door”, when closing, ensure that
the latches lock the door properly. For this purpose, keep the closing function operating for 2 or 3
seconds after the door is fully closed against the columns of the rear walls.
9.14. Never decouple the trailer / semi-trailer without first applying the brakes, placing the chocks on the
wheels and activating the drawbar’s hydraulic rest;
