6. Maintenance and Cleaning
The cable must be inspected before each use of the stand, as detailed above
(section 3), and also given at least an annual inspection to ensure that there
are no kinks, deformations, single strand breakage or cuts in the wire.
Defective wires must be replaced before the stand is returned to service.
The winch and stand are checked and lubricated during assembly, it is
recommended that the gear drive and handle threads be lubricated, and oil
applied to the bearings on the drum hub and the drive shaft. On no account
should oil or grease be applied to the brake mechanism.
The mast locking strips and locking pins should be checked at least annually
to ensure secure locking of the stand in its raised position. Particular
attention should be paid to the leading edges of the pin and strip, and to the
return spring.
The Zenith stand should be inspected annually by trained personnel. Any
replacement parts must be of original manufacture.
If spares are required, please quote the reference number from the drawings
included, and also the year of manufacture and serial number as marked on
the stand.
If parts not of original manufacture are used, or if the stand is modified in
any way, the user forfeits all rights to claim.
