General
37.1.6 Legibility of marking
If the fork arm marking in accordance with ISO 2330 is not clearly legi-
ble, the fork arm shall be removed from service.
37.1.7 Fork arm blade and shank
The fork arm blade and shank shall be thoroughly checked for wear,
special attention being paid to the vicinity of the heel. If the thickness of
the blade or shank is reduced to 90 % of the original thickness, or to the
minimum thickness specified by the fork arm or truck manufacturer, the
fork arm shall be withdrawn from service.
37.1.8 Fork arm mountings
The support face of the top hook and the retaining faces of both hooks
shall be checked for wear, crushing and other local deformations. If
these defects are apparent to such an extent that the clearance
between the fork arm and the fork carrier becomes excessive, the fork
arm shall be withdrawn from service. For other types of mounting, sim
-
ilar checks shall be carried out.
37.1.9 Repair and testing
Repair
Only the manufacturer of the fork arm or an expert of equal competence
shall decide if a fork arm may be repaired for return to service. The
repairs shall only be carried out in accordance with the recommenda
-
tions of the fork arm manufacturer. It is not recommended that surface
cracks or wear be repaired by welding. When repairs necessitating re-
setting are required, the fork arm shall subsequently be subjected to
appropriate heat treatment, as necessary.
Yield test
A fork arm that has undergone repairs other than repair or replacement
of the positioning lock and/or the marking shall only be returned to serv
-
ice after being submitted to, and passing, the yield test described in ISO
2330, with test load in accordance with the table.
