FIRST USE
AFTER THE FIRST 50 KILOMETRES, THEN AFTER THE NEXT 100 KILOMETRES, CHECK:
⇒wheel tightening ( REGULAR MAINTENANCE AND CHECKS - AXLES),
⇒tyre pressure
⇒in some cases, elements can be temporarily attached (for example: spare wheel support on spare wheel support
delivered without a spare wheel); remove them and store in a suitable location.
AFTER THE FIRST 500 KILOMETRES OR THE FIRST TRIP WITH A LOAD, CHECK:
⇒the self-steering axle geometry,
⇒the tightening of all self-steering axle nuts,
⇒the tightening of all mechanical suspension nuts,
⇒the tightening of all pneumatic suspension nuts.
AFTER THE FIRST 5,000 KILOMETRES:
Carry out the recommended maintenance checks ( REGULAR MAINTENANCE AND CHECKS - B OPERATIONS)
For all work on components bearing another manufacturer brand (axles, stands, hitch plate,
tailgate, etc.) please follow the equipment manufacturer recommendations
IDENTIFICATION
A FRUEHAUF identification plate as well as a cold heading are located on the vehicle chassis.

Be attentive to bridges, underpasses or tree branches that could damage your vehicle.
Your vehicle is designed to be driven with the tarpaulin closed, the roof closed and the rear door closed. Any other use is the
user’s liability.
Any possible accumulation of water, ice or snow on the top must be eliminated before the departure or handling of the vehicle.
Use suitable equipment to climb on / off your vehicle (retractable stepladders, ladders, stirrups, etc.). Wear suitable Personal
Protection Equipment when using the vehicle.
Do not stand inside or near the vehicle during manoeuvres.
All handling of bodywork should be manual.
For safety and maintenance instructions for equipment such as axles, stands and coupling plates, please refer to the manufacturer
user manuals.
This vehicle is designed for professional use, it must be used by qualified staff. It is intended for goods transport, any other use is
the user’s liability.
SAFETY INSTRUCTIONS
In order to avoid the excessive heating of brake components, use the engine brake or deceleration systems as much as
possible.
If your tractor is fitted with one, only use the trailer alignment brake in cases of absolute necessity.
Abusive and inappropriate use may result in:
• the very rapid wear of the brake linings on the towed vehicle,
• excess heating that may result in the tyres bursting or the vehicle catching fire
Transport of products for which the vehicle is not designed may result in damage to the bodywork, equipment or
safety devices and may ultimately cause serious accidents.
Respect the loading limits for the running gear and the coupling system (refer to the certificate of conformity and the vehicle
manufacturer plate Identification).
Loading/unloading must be carried out in compliance with the specific vehicle use directives. Regardless of the loading method, it
is compulsory that the vehicle brakes be applied and the wheels chocked.
To avoid tipping risks, it is imperative to couple the tractor or place supports at the front of the semi-trailer. In the case of tandem
vehicles or significant rear cantilevering, it is imperative to place
supports at the rear of the semi-trailer if the tractor is not coupled.
In exceptional cases, if the GVW is higher than 5 tonnes, it is essential to place elements such as beams or metal plates on the
floor perpendicular to the vehicle longitudinal axis and to place supports at the rear of the semi-trailer.
LOADING
During loading or unloading, standard trailers and semi-trailers are designed to support fork lift trucks with a total
GVW, Gross vehicle weight (fork lift + load) of a maximum of 5 tonnes.

8
To avoid pallet container or other packaging stands or rollers from piercing and breaking the floor, it is imperative to use spreader
plates.
Check that the load is evenly spread and that it complies with the intended vehicle conditions.
Loading / unloading on a dock:
Make sure the vehicle is horizontally aligned with the dock,
if necessary, adjust using the Up and Down handle.
If necessary, repeat the operation during the manoeuvre.
equipment and common options - “Up and down” system
For specific loading: Curtains - tippers - container beds - city-urban
LOADING
Load safety:
To prevent the load from moving during transport, check that it is
correctly attached and blocked.
In the absence of special indications resulting in a special construction, the vehicles are designed to transport loads
of a uniform weight on the entire floor surface. All concentrated loads must be placed on a rigid frame. The frame
strength must fulfil the following conditions:
Concentrated load weight
Load surface area
Working load
Total floor surface area
< or =

Respect the hitching height indicated on the vehicle order form.
A - BEFORE HITCHING, CHECK:
• The hitching unit:
⇒hitch plate condition and fixing
(no sheared metal, warping, depressions),
⇒the hitch shaft condition and fixing,
⇒the hitch plate and weight carrying hitch plate grease coat.
It must be sufficient and free of any foreign bodies so that the hitching of the tractor to
the semi-trailer is perfect and causes no damage,
⇒to lubricate the hitch plate and shaft and the weight carrying hitch plate.
REGULAR MAINTENANCE AND CHECKS - HITCH SHAFT
• That the parking brake is applied
EQUIPMENT AND COMMON OPTIONS - PNEUMATIC BRAKE CONTROL
• That the hitch plate is at the correct height relative to the weight carrying hitch plate
If necessary, use the stands to achieve a correct position ( EQUIPMENT AND COMMON OPTIONS
- STANDS) to raise or lower the front of the semi-trailer.
It is strictly prohibited to move the semi-trailer when supported on the stands, even if the stands
are on wheels.
HITCHING
B - TO HITCH:
• Slowly reverse the tractor, in line, until the hitch plate comes into contact with the weight carrying hitch plate,
• Gently and progressively accelerate while engaging the gears to:
⇒smoothly slide the weight carrying hitch plate under the hitch plate,
⇒gently strike the jaws using the hitch shaft. The impact automatically locks them.
• Carry out the traction test
With the parking brake applied, put into 1st gear and slightly accelerate; the driver must be able to feel significant resistance
to moving the vehicle forward.
• Check that the weight carrying hitch plate is properly locked
in compliance with the sticker applied on the vehicle
All these checks must be carried out. Incorrect locking may result in unexpected unhitching during
use, which would cause serious damage or even very serious accidents.
CAUTION
DANGER!!!
IT IS MANDATORY TO CHECK THAT THE WEIGHT CARRYING HITCH PLATE IS
PROPERLY LOCKED AND THAT ITS HANDLE IS IN POSITION BEFORE MOVING
