4.3. Operation

"On-site" trailer
These trailers are not fitted with a main brake, and so cannot be braked in motion; the tyres allow for a maximum speed of 27 km/h. So
it is absolutely prohibited to exceed this speed.
Nor are these trailers fitted with signalling lights. On-road use is prohibited.
"On-road" trailer
The driving speed must be suited to the condition of the road and the handling of the trailer.
Driving at high speed causes heating of the tyres; so it is important to stop from time to time, and check them. Excessive heating may
cause a puncture, and therefore a serious accident. For reversing manoeuvres, remember to lock the inertia brake.
Particular
In the first few miles' driving, heating of the brake hubs and drums will actually reduce the wheel tightness. It
is therefore essential to check the tightness every 6 miles (10 kilometres) until no further loosening is noted.
Nonetheless the tightness must be checked whenever you are about to tow the trailer.
Warning
Lights/signalling (only for "on-road" trailers)
Warning lights are obligatory for on-road driving. Signalling must comply with regulations in force in the country of use.

Refit the hitch using the wheel to release the hook ring from the tow vehicle.

4.5. Implementation for installation

Operations to be carried out:
 Ensure that the ground is strong enough for the assembly not to sink into it.
 Unhitch the trailer as per paragraph 5.2.1 "Hitching and unhitching the trailer".
 Immobilise the trailer by placing chocks under the wheels.
 Fully engage the parking brake (if fitted).
 Using the front wheel, position the generating set as close to horizontal as possible.
 Lower the stands (if fitted), and lock them.
