Take the crane, at least once a year, to a Hiab authorised service workshop for inspection and
maintenance.
The workshop must carry out the following maintenance tasks at least once a year.
Hydraulic oil
• Change the hydraulic oil.

If the workshop is equipped and the personnel prepared to do a test of the oil
quality and think that the oil change is not needed, they can postpone it on their
own responsibility.
Hydraulic system oil tank filler cap
• Change the filler cap.
• Replace filters.
Slewing housing
• Change oil in the slewing housing.
Hooks
• Replace missing or faulty parts on link assembly: shafts, safety pins and nuts.
• Replace the hook for a new one if the hook is damaged.
• Replace the latch assembly if it is damaged, missing or malfunctioning.
•
Hook 8 t and 10 t (without spring/roll pins):

new ones, at least once a year.
8.4. Lubrication
General greasing of the cranes
Incorrect or insufficient lubrication of a crane is the number one cause of premature failure.
WARNING
Before and after a long stop of the crane, lubrication is absolutely necessary. This
is especially important after a winter shutdown.
WARNING
Follow the lubrication schedule exactly. If you do not do so, you can cause serious
damage to the crane and to add-on equipment.
