When the support point is at one end
and the other end is free, the lower part
is pressed and the upper part is pulled.
In this case, cut approximately 1/3 of
the diameter upwards and then
downwards in the same position.
When both ends are supported, the
upper part is pressed, and the lower
part is pulled.
In this case, cut approximately 1/3
of the diameter downwards and then
upwards in the same position.
Wooden wedge
Cut obliquely and one end can
smoothly fall down.
Warning
If the pulled or pressed part of timber is not determined
correctly and cutting is started in the wrong direction,
the chain on the guide plate of the chain saw will be
extruded and cannot be moved in the timber seam.
If the engine is rotating but the chain is stuck, the
clutch of the chain saw will be burnt.
If the chain is stuck and the chain saw cannot be taken
out of the chain, the saw must not be dragged out in a
forced manner. Immediately stop the engine, insert the
wooden wedge into the seam to expand the seam, and
take out the chain.
Do not drag the chain saw if the chain is stuck.
The blunt chain is not safe and the wear of the cutting
edge will be increased. A good method to judge the
chain bluntness is to check whether the sawdust is
fine, instead of normal sawdust.
Warning
After operation of the chain saw, the hot cylinder head
surface and muffler cover must not be touched.
