1.6.8 Towed machines
¾
Pay attention to the permissible combinations
of hitching device on the tractor and drawbar
hitch on the machine!
Couple only permissible vehicle combinations
(tractor and towed machine).
¾
In case of single-axle machines pay attention
to the maximum permissible drawbar load of
the tractor on the hitching device!
¾
Always ensure sufficient steering and braking
capacity of the tractor!
Machines mounted to or towed by a tractor
affect the travel behaviour as well as the steer -
ing and braking ability of the tractor, especially
single-axle machines with drawbar load ap-
plied to the tractor!
¾
For drawbars with drawbar load, the height
of the drawbar must only be adjusted in a
specialist workshop!
1.6.9 Brake system
¾
Adjustment and repair work on the brake
system must only be carried out in expert
workshops or established brake service
workshops.
¾
Immediately stop the tractor in case of brake
system malfunctions.
Have the malfunction remedied immediately.
¾
The brake system must be thoroughly
checked at regular intervals.
¾
Securely park the machine before starting
work in the brake system. Secure the machine
against unintended lowering and rolling away
(wheel chocks)!
¾
Be extra careful when performing welding,
flame cutting or drilling work near brake lines!
¾
After setup and repair work on the brake sys-
tem you must generally carry out a brake test!
¾
Pay attention to the corresponding regulations
(France) when changing the hydraulic oil!

ter the operating pressure required to release
the brake has been reached (pressure gauge
on tractor).
¾
Before coupling the machine clean the seal
rings on the coupling heads of the supply and
brake line from possible contamination!
¾
Close the coupling heads on the tractor before
driving without machine!
¾
Close the coupling heads of supply and brake
lines and hook these into the brackets pro-
vided for this purpose!
¾
Drain the air vessel daily!
¾
The specified settings on the brake valves

corroded, loose or missing.
1.6.11 Tyres
¾
When working on the tyres make sure that the
machine has been parked safely and properly
secured against rolling away and accidental
lowering (parking brake, wheel chocks).
¾
The assembly of wheels and tyres requires
profound knowledge and the use of proper
assembly tools!
¾
Repair work on tyres and wheels must only be
carried out by specialists and only with the ap-
propriate assembly tools for this kind of work!
¾
Check the air pressure regularly! Pay attention
to the specified air pressure!
¾
Check the wheel nuts regularly and retighten
all fastening screws and nuts as specified by
HORSCH LEEB AS GmbH! Failing to do so
can lead to loosing wheels and thus to the
machine tipping over.
