6 Maintenance

Study the instructions carefully and pay special attention to the warnings!

6.1

Maintenance

1. Periodically check the condition of the gasket, wash it and carefully dry it. Replace if necessary.
2. The process of control and periodic washing is also valid for the seat of the gasket on the cover.
3. Periodically check the state of the closing systems, eyebolts and handles. Replace if necessary.

NOTE
Special Maintenance only valid for the LDK and O-series with SS wing handle:
1. After 24 months of operation, check cross arm. Verify that the cross arm has not been subject to excessive stress due

to overstraining of the SS-wing handle. (Applying excessive force on the SS-wing handle during tightening will deform
the cross arm over time).
