For your safety
Basic safety instructions
Please read the following safety instructionscarefullybefore using the product for the first time.
▪Nobody must stay in the proximity of the tractor or trailed implement during operation.
▪Never remove any safety mechanisms or stickers from the product.
▪Read the operating instructions to the agricultural device which you want to control by using the
product.
▪Before charging the tractor battery, always disconnect the connection between the tractor and
the terminal TRAIL-Control II.
▪Before welding on the tractor or implement, always disconnect the power supply to the terminal.
▪Before maintenance or repair to the tractor, always disconnect the connection between the
tractor and the terminal.
▪Do not make any unauthorized modifications to the product. Unauthorized modifications or use
may impair safety and reduce the service life or operability of the unit. Modifications are
considered unauthorized if they are not described in the product documentation.
Hazard Area
The hazard area covers an area of several meters around the tractor and towed equipment in all
directions. The greater the size of the towed equipment, the greater the hazard area. For example:
The wider the spraying rods of an agricultural sprayer, the further it can swing out and therefore its
hazard area is greater.
WARNING
Danger of Injury from Uncontrolled Machine Movements
◦Pay attention that nobody enters the hazard area!
◦Switch off the system immediately, as soon as a person enters the hazard area!
As soon as the system has been assembled and switched on, nobody may remain in the hazard
area.
When the TRAIL-Controll II is switched on, there is a risk that pressure fluctuations in the hydraulic
system could cause the drawbar or the steering knuckle to move uncontrolledly.
Pressure fluctuations can, for example, occur in the following instances:
▪If the hydraulic system is defective
▪If the hydraulic system is used for purposes other than for controlling steering ofthe drawbar and
knuckle.
The hazard area may then only be entered if the following conditions are fulfilled:
▪The person entering the area must be informed of the potential dangers
▪All activities must be precisely agreed between the driver and the person appointed to enter the
area.
▪All maintenance, configuration and monitoring work must, if possible, be conducted when the
system is switched off.

Safety signs on the machine
You receive a safety sign adhesive label together with the product.
This label must be attached near the bend area with drawbar steering.
When attaching safety signs, observe the following:
▪Safety signs must be attached at a visible location so that they can be seen by everyone
approaching the danger zone.
▪If the danger area can be approached from several sides of the machine, attach the warning
signs on all machine sides.
▪Regularly check the safety signs for completeness and legibility.
▪Replace damaged or unreadable signs with new ones.

Instructions on retrofitting
Instructions on how to retrofit electrical and electronic farm equipment and/or
components
Agricultural equipment used today features electronic components and parts whose function can be
affected by other farm equipment which emits electromagnetic waves. Such effects could lead to
personnel being put in danger, if the following safety instructions are not adhered to.
When selecting components, make sure first of all that the retrofitted electricaland electronic
components comply with the current version of the EMC Directive 2004/108/EC and carry the CE
marking.
When retrofitting a machine with electrical and electronic farm equipment and/or components
connected to the vehicle's electrical system, it is your own responsibility to check whether the
installation causes interference with the vehicle's electronic system or other components. This
applies, in particular, to the electronic control of:
▪electronic hitch control,
▪front linkage,
▪power take off (PTO),
▪engine,
▪gear.
The following requirements must be met in order to retrofit mobile communication systems (e.g. radio,
phone):
▪All farm equipment must be approved and installed in accordance with the regulations applicable
in the respective country.
▪The equipment must be installed as a fixed installation.
▪The operation of portable or mobile farm equipment in the interior of the vehicle isonly permitted
via a connection to a permanently installed exterior antenna.
