10 Maintenance
Keep the machine in good condition to obtain optimum performance from your machine and to
guarantee the safety of the users.
This chapter describes
• the maintenance jobs to be carried out
• the required skills for the maintenance jobs
• the time-intervals the jobs have to be performed in.
The time intervals are given for regular frequency of use and normal severity of service
conditions.
The time intervals have to be taken proportionally shorter when
o the system is applied more often than regular, which is once per month
o the system is used in exceptional service conditions, like wet or salty
environments
o the system is applied to the limits of its capacity
o the system is applied for special service. The time interval has to be discussed
with Enerpac.
• The time intervals may be varied based on experience gained on the service life of
systems used in similar circumstances.
• If the system was idle for at least 6 months, all inspections as listed in the following
section with a prescribed frequency of at least 6 months have to be performed.
