Like all technical equipment, the vehicle
requires care and maintenance. The scope and
frequency of maintenance work mainly depend
on the operating conditions, which can differ
widely.
You must secure the vehicle on axle stands of
sufficient load-bearing capacity if work is being
carried out underneath the vehicle.Never use
the jack instead of stands. The jack could slip
and the vehicle could drop. The jack is only
intended to raise the vehicle for ashort time.
When working on the vehicle,comply with all
safety regulations, such as operating instruc-
tions, regulations concerning hazardous mate-
rials, environmental protection measures,
work safety and accident prevention regula-
tions.
Inspection and maintenance work requires
specialskills that cannot be acquired by read-
ing these Operating Instructions. Alwayshave
this work and maintenance work carried out
by aqualifiedspecialist workshop.
