3. Check the straightness of the upper face of
blade (D) and the front face of shank (E) with a
straight edge.
The fork should be withdrawn from service if the
deviation from straightness exceeds 0.5 percent of
the length of the blade and/or the height of the
shank respectively 5 mm/1000 mm (0.18Ó/36Ó).
4. Check the difference in height of one fork tip to
the other when mounted on the fork carrier.
A difference in fork tip height can result in uneven
support of the load and cause problems with
entering loads.
The maximum recommended difference in fork tip
elevation (F) is 6.5 mm (0.25Ó) for pallet forks and
3 mm (0.125Ó) for fully tapered forks. The maxi-
mum allowable difference in fork tip elevation
between the two or more forks is 3 percent of
blade length (L).
Replace one or both forks when the difference in
fork tip height exceeds the maximum allowable dif-
ference.
