Maintenance
The TGMD does not require any lubrication as all the moving parts have sealed or dry running
bearings. However, the following routine checks must be carried out on the trolley:
5.1
Every 3 Months
•
Visually inspect the TGMD for signs of damage. If necessary, contact your distributor for
help.
•
Check that when the trolley is assembled, there is no play in the central joint.
5.2
Annual
The TGMD must be returned to Abtus Ltd annually for re-calibration to ensure measurements are
within specification. The condition of all components will be checked at this time and replaced as
required. Each trolley should have at least one trained operator who is responsible for returning the
trolley.
The trolley is marked with a calibration sticker inside of the battery compartment showing the next
annual due date and must be returned to Abtus for annual calibration and maintenance. If the trolley
is used beyond the calibration due date, the performance may be degraded.
If the equipment becomes defective, or if it has an out of date calibration sticker, a warning notice
should be placed on the device to prevent further use and should be returned to Abtus for repair,
maintenance and re-calibration.
