Difference in height between the fork tips
Check a set of forks to see if there is any difference in height once they
are installed in the fork holder. If the difference in tip height exceeds 3%
of the blade length or the limit value recommended by the truck manu
-
facturer, the set of forks in question must be taken out of service.
Affected fork sets must not be used again until they have been readjust-
ed and tested as per "15.4.2 Forks, repairs and testing".
Position locks
Check that the position lock (if included in the delivery) is in good condi-
tion and fully functional. If any fault is found, the fork must be taken out
of service until it has been repaired in a satisfactory manner.
Legible markings
If the marking on a fork as per ISO 2330 is not clearly legible, the fork
must be taken out of service.
Fork blades and shafts
The fork blade (a) and shaft (b) must be carefully checked for wear. Pay
particular attention to the area around the tilt stop. If the thickness of the
blade or shaft has been reduced to 90% of the original thickness, or to
the minimum thickness specified by the fork or truck manufacturer, the
fork must be taken out of service.
Mounting fixings on the fork
Check the upper hook’s support surface and the attachment surfaces of
both hooks for wear, crushing or other localised deformation. If the
defects are so obvious that play between the fork and fork holder
becomes excessive, the fork must be taken out of service. Perform sim
-
ilar checks on other types of mounting fixings.
