6.1 Service schedule
Regular maintenance reduces operating faults, repair costs and downtime.
This maintenance schedule uses values that are valid for most applications. For a specific ser-
vice interval, see 6.1.1 Calculating a customer-specific maintenance plan, page 14.
Implement a safety-related maintenance program that takes the local regulations for repair and
maintenance for all operating phases of the tool into account.
CAUTION!
Danger of injury due to unintentional activation
– before service, disconnect the tool from the compressed air supply.
