6. Ensure that all locking pins are engaged on the mast sections by rotating the

winch handle counter-clockwise until the masts stop descending. Rotate the

handle clockwise to remove any slack from the wire after checking.

Lowering:

1. To start lowering the load, ensure that the cable is tight and supporting the load.

2. Disengage the locking pin from the mast section by pulling and holding the pin

outwards.

3. While holding the locking pin outwards, rotate the winch handle (see figure 3)

counter-clockwise as indicated on the winch body to lower the mast section.

4. Rotate the winch handle (see figure 3) counter-clockwise as indicated on the

winch body to lower the mast section.

5. When the mast section reaches its base position, pull and rotate the locking pin

into the lock position to secure the mast (see figure 1).

6. Repeat the above actions for the remaining mast sections until the stand is fully

retracted.

7. The load may now be removed from the stand and the stand folded ready for

transport.

Before attempting to move the stand, ensure the load is removed, and the

locking pins (figure 2-7) retain the mast sections.

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. If spares are

required, these should be obtained from Doughty Engineering Limited. Please quote the

reference number from the drawings included, 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.
