Forks
Inspect the load forks for cracks, breaks, bending and wear. The fork top
surfaces shou Id be level and even with each other. The height difference
between both fork tips should be no more than 3% of the fork length.
WARNING
If the fork blade heel is
worn down by more
than 10 per cent, the
load capacity is
reduced and the fork
must be replaced.
10% of "A" is
max. wear
Inspect the forks for twists and
bends. Put a 2"-thick wood block,
at least 4" wide by 24" long, on the
blade of the fork with the 4" sur-
face against the blade. Put a 24"
carpenter's square on the top of
the block and against the shank.
Checkthe fork 20" above the blade
to make sure it is not bent more
than 1" maximum.
If the fork blades are obviously
bent or damaged, have them
inspected by a trained mainte-
nance person before operating
the truck.
3% of "B" is max.
height difference
2" X 4'
Inspect the fork stop pins. Be sure they are not damaged or broken and
operate freely. Check the stop pins for secure condition.
