MAINTENANCE
To maintain optimum performance and safety, regular maintenance needs to be carried out. This section
details the user maintenance required; other maintenance or repairs should be carried out by Norbar or a
Norbar approved agent and should form part of a service. Service intervals will depend on the type of usage
of the tools and the environment in which they are being used. The maximum recommended maintenance
and recalibration interval is 12 months.
TIP:
Steps the operator can take to reduce the amount of maintenance required include:
1. Use the tool in a clean environment.
2. Use an air compressor fitted with a dryer.
3. Ensure the Lubro Control Unit has sufficient hydraulic oil.
4. Ensure the Lubro Control Unit delivers hydraulic oil at the correct rate.
5. Ensure the Lubro Control Unit is regularly maintained, see product manual.
6. Maintain the correct torque reaction.
Reaction Plate
Every week check that the bolts fastening the reaction plate are tightened to the torque stamped onto the
reaction plate.
Air Lubrication
Add Fuchs Silkair VG22 or Shell Tellus S2 VX15 or equivalent good quality hydraulic oil to the Lubro control
unit.
Gearbox
Under normal operating conditions it is not necessary to re-grease the gearbox. The gearbox contains Shell
Gadus S2 V220 or equivalent good quality grease.
Silencer
The silencer (#19188) should be changed every 12 months.
This may be more frequent for high tool usage or dirty environments.
To change silencer:
1. Remove circlip from end of sleeve.
2. Slide sleeve to access silencer.
3. Change silencer.
4. Refit sleeve and circlip.
Filter
The air filter (#18280) should be changed every 12 months.
This may be more frequent for high tool usage or dirty environments.
To change filter:
1. Switch off air supply to tool.
2. Remove inlet air hose.
3. Remove filter from inside tool air inlet.
4. Fit new filter.
