- Check up the hydraulic hoses for wear. Replace them if necessary or every
four years at least.
To Change or to Tighten the Chain
Check up regularly the link chain for wear and proper tightening. The chain too
much taut or conversely too slack brings also its shorter service life. Check up also
all chain tips for wear and completeness. If one of them is damaged, change it
immediately.
Change of Worn Tips
Particular chain tips are fitted as left and right by means of two steel bolts on the
chain link. The tips can be changed in singles any time according to their wear.
Should the tips be changed, be aware of their alternating direction
(left and right). If wrong, functionality of the chain can be limited
considerably. The tips must be properly fitted (screwed down) to their links.
Chain Tension
It is necessary to check the chain slack regularly. Too much slack brings negative
impact on service life of the chain itself and even of its bar or drive wheel
.
The recommended chain slack should be approximately 30 – 40 mm
(measured in the horizontal position of the bar and in the middle of
the chain length), see next fig.
