MAINTENANCE
WARNING:
For optimum performance and safety, regular tool maintenance is required. The user maintenance is limited to
that stipulated in this section. Any other maintenance or repairs should be carried out by Norbar or a Norbar
distributor. Maintenance intervals will depend on the tool usage and the environment in which it is being used.
The maximum recommended maintenance and recalibration interval is 12 months.
TIP:
Steps the user can take to reduce the amount of maintenance required include:
1. Use the tool in a clean environment
2. Maintain the correct torque reaction
3. Carry out daily checks
Daily Checks
It is recommended to check the overall condition of the tool every day.
Check power cord for damage – if faulty contact Norbar or Norbar distributor.
Ensure PAT test on tool is within date.
Test the external RCD in the mains supply (if fitted).
Ensure tool is clean - DO NOT use abrasives or solvent based cleaners.
Ensure fan and ventilation slots are clean and dust free. If cleaned with compressed air wear eye protection.
Free run tool to ensure motor and gearbox are smooth and quiet.
Calibration
Your tool has been supplied with a certificate of calibration.
To maintain the specified accuracy it is recommended that the tool is recalibrated at least once per year.
Recalibration should be carried out at Norbar or by a Norbar distributor, where all the facilities to ensure the
instrument is functioning at maximum accuracy are available.
Do not remove tool casing; there are no calibration settings inside.
Portable Appliance Testing
Portable Appliance Testing (PAT testing) is officially known as "In-service Inspection & Testing of Electrical
Equipment".
This is often a mandatory requirement in local regulations or factory procedures.
The tests are to ensure that the equipment has not suffered damage or faults in the electrical connections that
could cause potential danger to the operator.
A competent person should inspect then test the tool for earth continuity (Earth Bond) and Insulation resistance
(Electric Strength); other tests may apply.
The frequency of test will depend on many factors including the tool application and environment.
ENSURE THE TOOL IS DISCONNECTED FROM MAINS SUPPLY BEFORE
MAINTENANCE.
