The aim of maintenance is:
○ that the commissioned trailer is kept
operating safely and performing prop-
erly during use,
○ to prevent downtimes,
○ to keep the costs of operational readi-
ness reasonable and financially justifi-
able,
○ and to limit unavoidable repair ex-
penditures.
10.2.1 Regular checks and functional
testing
To ensure that the trailer is in proper oper-
ating condition, the safety-related equip-
ment must be checked regularly for proper
function, its effectiveness must be ensured
and the recurring inspections must be per-
formed.
► Prior to starting each trip, perform a
departure check (see "7.1 Commissioning
before each trip", pg.88).
► Perform legally prescribed general in-
spections punctually.
► Observe the intervals and instructions
for testing and maintenance of the
supplied components (e.g. axles) con-
tained within the respective supplied
operating instructions.
► Report any detected safety defects:
○ Take the trailer out of operation if oper-
ational safety is not ensured.
○ When there is a change of shift, inform
the colleague starting the next shift
about observed defects and implemen-
ted measures.

tional testing at the intervals pre-
