D-1
Inspect the Forks
Genie specifications require that this procedure
be performed every 1000 hours or annually,
whichever comes first OR whenever permanent
deformation of the forks is suspected.
Maintaining the lifting forks in good condition is
essential to safe operation and good machine
performance. Failure to detect damage to the forks
could result in a hazardous operating condition.
1 Thoroughly clean the lifting forks.
2 Inspect the forks for the following:
• Surface cracks
• Straightness of the blade and shank
• Fork angle at 90 ± 3 degrees
• Relative height of fork tips shall not differ
more than 3% of blade length
• Excessive wear to the forks, fork mount or
legible markings
Result: If any of the above criteria are not met,
forks shall be removed from service until they
are repaired or replaced.
