Springpole
A springpole is any log, branch, rooted stump, or
sapling which is bent under tension by other wood
so that it springs back if the wood holding it is cut
or removed. On a fallen tree, a rooted stump has
a high potential of springing back to the upright
position during the bucking cut to separate the log
from the stump. Watch out for springpoles, they are
dangerous.

Be careful to file all cutters to the specified angles and
to the same length, as fast cutting can be obtained
only when all cutters are uniform.
• Wear gloves for protection. Properly tension the
chain prior to sharpening. Refer to Chain Tension
section earlier in this manual. Do all of your filing at
the mid-point of the bar.
