4. MAINTENANCE
4.1 MAINTENANCE GENERAL
CAUTION:
OBSERVE THE SAFETY PRECAUTIONS MENTIONED IN
SECTION 1.7 BEFORE MAINTENANCE!
Although Neles actuators are designed to work under severe
conditions, proper preventative maintenance Can signicantly help
to prevent unplanned downtime and in real terms reduce the total
cost of ownership. Neles recommends inspecting the actuators at
least every ve (5) years. The inspection and maintenance interval
depend on the actual application and process condition. The
inspection and maintenance intervals can be specied together with
your local Neles experts.
During this periodic inspection the parts detailed in the Spare Part
Set should be replaced. Time in storage should be included in the
inspection interval.
If maintenance assistance is required, please contact your local
Neles o󰀩ce. The part numbers in parentheses () in the text refer
to the exploded view and to the parts list in Section 8, unless
otherwise stated.
