Inspection and Maintenance
As with all rigging equipment, Broadweigh Bluetooth shackles should be inspected before and after every use,
ensuring that all the components are present and correct (bow, pin, bobbin, nut and r clip) and the serial numbers
match. All load bearing components must be free from cuts, nicks, cracks, gouges or excessive wear and
distortion. Any damaged Broadweigh shackles or components must be taken out of service and returned to your
dealer to arrange refurbishment or scrapping. If you attempt to replace or swap any load bearing parts yourself
the unit’s calibration will be void.
It is also important before every use to check that all the settings are as expected. The most safety critical settings
to check are that the system zero and the units are correctly set (see the relevant sections in the manual). If these
have been unknowingly changed you could end up with unexpected and misleading readings.
Before moving system zero or checking any readings please ensure that the shackle’s temperature has stabilised.
When moved from different temperatures it can take up to an hour to reach the local ambient temperature. Once
it has done so, the readings can accurately be checked.
Always remember that damage to the shackle or its calibration can happen at any time. If you need to move the
system zero significantly then further investigation is required. This could take the form of a thorough
examination and calibration check with a known load. Records should be kept of any calibration check so that you
can see any movement over time. If the readings are out by more than 1% or 25 kg or you have to zero out more
than 50 kg, please return to your dealer to arrange recalibration.
These measures should be used in conjunction with your own thorough examination routine at the same intervals
you have set for normal shackles. This will vary due to local regulations but should not be less than every 6
months. Records of all thorough examinations should be kept.
We would recommend checking your shackle’s output with a known load at least once a year and a return to the
factory for a calibration check every two years.
There are very few maintenance requirements. The Broadweigh shackles, TwistLinks and battery enclosures need
to be kept clean, threads clear of debris and protected from corrosion.
Do not overtighten screws when replacing batteries. Damage caused by overtightening is not covered under
manufacturer warranty.
Remove the batteries if being stored for an extended period. Leaking batteries can damage the circuitry and pin.
