To disassemble the stand prior to moving, perform the above actions in
reverse order (6-1).
5. Operation
Lifting:
1. To start raising the stand, pull and rotate the upper locking pin (figure
2-7) to disengage the pin from the transport position and locate in the
raising position (see figure 1) and rotate the winch handle (figure 2-8)
clockwise, as indicated on the body of the winch.
2. The locking pin (figure 2-7) can be released once located in the raising
position and will continue to operate on a ratchet.
3. Continue winding the handle (figure 2-8) until the mast either stops
moving (top of stroke), or the desired height is achieved.
4. To release the next mast section, pull and rotate the locking pin to
locate it in the raise position.
5. Repeat steps 3 and 4 for the remaining section.
6. Ensure that all locking pins (figure 2-7) are engaged on the mast
sections by rotating the winch handle (figure 2-8) 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. Pull the locking pin (figure 2-7) to disengage it from the mast section,
and rotate it to the down position.
3. Rotate the winch handle (figure 2-8) counter-clockwise as indicated on
the winch body to lower the mast section.
4. When the mast section reaches its base position, rotate the locking pin
(figure 2-7) to the transport position to secure the mast.
5. Repeat the above actions for the remaining mast sections until the
stand is fully retracted.
6. The load may now be removed from the stand and the stand folded
ready for transport, see section 4 for the procedure.
Before attempting to move the stand, ensure the load is removed, and the
locking pins (figure 2-7) retain the mast sections.
