Tension and compression in timber
If you have misjudged the effects of tension and com-
pression, and cut from the wrong side, the timber will
pinch the guide bar and chain, trapping it.
If the chain should become jammed and the saw can not
be removed from the cut do not force it out.
Stop the saw, force a wedge into the cut to open it up.
Never force the saw when it is jammed.
Do not force the saw into the cut.
A dull chain is unsafe and will cause excessive wear to
the cutting attachments.
A good way to tell when the chain is dull is when fine
saw dust comes out instead of chips.
A length of timber lying on the ground will be subject to tension
and compression, depending at which points the major sup-
port is.
When timber is supported at its ends the compression side is
at the top and the tension side is at the bottom.
To cut between these support points, make the first cut down-
wards approximately 1/3rd the timber diameter.
The second cut is made upwards and should meet the first cut.
Heavy stress
When the timber is supported at one end only, make the first
cut upwards approximately 1/3rd the timber diameter.
The second cut is made downwards and should meet the first
cut.
Overbuck
Underbuck
Make angled cut when one section may settle against the oth-
er.
