LIMBING THICK BRANCHES
When limbing thick branches, the guide bar may get
pinched easily• Branches under tension often snap
up, so cut troublesome branches in small steps•
Apply the same principles as for cross cutting• Think
ahead and be aware of the possible consecuences
of all your actions•
CROSS CUTTING/BUCKING
Before starting to cut through the log, try to imagine
what is going to happen• Look out for stresses in
the log and cut through it in such a manner that the
guide bar will not get pinched•
CROSS CUTTING LOGS, PRESSURE ON TOP
Take a firm stance• Begin with an upper cut. Do
not cut too deeply, about 1/3 of the log diameter is
enough• Finish with a bottom cut.
The saw cuts should meet. (Fig. 21 )
