14. Repair

The following repair measures may only be performed
by qualified persons with the necessary knowledge and
skills.
In the case of the repair of a chain leg, the chain must
be replaced in its entire length. Parts that are broken,
visually deformed or stretched or severely corroded,
with deposits that cannot be removed (e. g. weld spatter),
deep cuts, notches, grooves, incipient cracks or which
are overheated, must be replaced. Missing safety de-
vices such as latches, triggers, pins or defective, broken
or deficient springs must be replaced. Only use original
PFEIFER spare parts and accessories of the appropriate
quality grade and nominal size when replacing. Only use
new bolts, adapter sleeves and other safety elements.
Missing WLL identification tags must be replaced by
a new tag after inspection and if necessary, after repair
of the suspension, provided the working load limit can
be clearly identified based on the stamping of the indivi-
dual parts and their design.
Documentation
A qualified person must perform the tests and their
results and the repair must be documented in the chain
card file and be kept over the entire service life of the
chain. These records and the test certificate or the certi-
ficate of conformity of the manufacturer must be shown
upon demand to the respective national work safety
inspection.
