MAINTENANCE AND REPAIRS
The stipulated values for the angles A and B achieve automatically, if you use the
stipulated files and filing machines and if there is a right adjusting.
The angles have to be the same to all teeth of the chain. If the angles differ from each other: the
running of the chain is rough, uneven, and the wear gets tougher – this can go on to the break
of the chain.
Being fulfilled only after enough and intense practicing: Use a file holder! *
File super chains by hand only with the aid of the file holder! File holders have got markings for
the file angle!
Controlling the angle
Filing gauche * (look list) a versatile tool for the check of sharpening angle and front angle, the
height of the depth limiter, lenght of tooth, depth of the groove and for the cleaning of the groove
and oil inlet bores.
The right sharpening
- if using the file holder and FG 1:
- te chain still stays on the guide bar
- if necessary fix the guide bar
- block the chain - hand guard to the front
- for going on pulling back the chain pull the hand guard to the hand pipe
- sharpen often (do not take away much) - for simple resharpening two to three file lines are
enough
- file only from the inner side to the outer
- the file only graps in the forward line - if you move at back lift it up.
- Guide the file:
Horizontal (in a 90° angle to the side surface of the guide ba r) corresponding to the
mentioned angles - of the markings on the file supports
- Do not file the connecting links and drive links
- Turn the files in regular spaces, to avoide wear on one side only
- Remove file burr with a piece of hard wood
- Check the angle with the filge gauge.
All cutting theeth must have the same length
When the length of the teeth is unequal also the hight of the teeth is different and that causes a
rough running of the chain and cracks in the chain.
File all cutting teeth to the length of the shortest. This can last very long so you better do this in
a work shop with an electric sharpening machine.
