- If pneumatic wrenches have been used, the torques should still be checked
using a torque wrench.
- Do not force the torque wrench by using extensions (pipes or similar).

Mast: tension and length of mast chains (fig. 1)
The tension and length of the mast chains should be checked regularly. They stretch
gradually due to the strain applied to them.
The mast chains should be replaced when their nominal length has increased by 3%.
Length can be checked by counting the links in one meter of 5/8” chain. Nominally there
should be the length of 61 links. The change should be made when there is the length
of 62.5 links, or a maximum of 63.
The chain is tensioned by turning the stop nut (a) of the tensioning rods.
