Storage, Servicing and Maintenance
1. General
The hydraulic pre-tensioning jacks must be kept in their tool boxes when not in use.
After you use the pre-tensioning jacks, close the connections with plugs and apply
grease. We recommend that, for each jack, you keep a sealing kit (KJ−) in stock.
Always make sure that new back-up rings and O-rings are installed in their correct
positions, as shown in the data that follows.
Note: Carefully install new back-up rings and O-rings to prevent damage. Do
not use tools with sharp edges.
Put uncut back-up rings in hot water before you install them.
