6.5  MAINTENANCE OF ELECTRICAL SYSTEM AND WARNING 

ELEMENTS

Work connected with the repair, change 
or regeneration of electrical system com-
ponents should be entrusted to specialist 
establishments, having the appropriate 

technology and qualifications for this type 

of work.
The duties of the user include only tech-
nical inspection of electrical system and 

reflectors.

PROCEDURE

•  Connect trailer to tractor with appro-

priate connection lead.

•  Check if the connection lead is re-

liable. Check connection sockets in 
tractor and trailer.

•  Check completeness and technical 

condition of trailer lights.

• 

Check completeness of all reflectors.

•  Check correct mounting of the slow-

moving vehicle warning sign holder.

•  Before driving on to public road, 

check that the tractor is equipped 

with a warning reflective triangle.

J.3.2.589.05.1.EN

TIP

Light-emitting diodes (LED) are used as the source 

of light. Damaged lights can be replaced only as 

complete units. It is impossible to repair or regener-

ate them.

Do NOT travel with out of order lighting system. 

Damaged lamp lenses must be replaced immediate-

ly before travelling. Lost or damaged reflectors must 

be replaced.

Before driving off, make certain that all lamps and 

reflectors are clean.
