down into the tree, using the ribbed bumper as a hinge.
4. Once the pruner gets to a 45 ° angle, level the pruner
again and repeat steps until you cut fully through.
5. When the tree is supported along its entire length, make
a cut from the top (overbuck), but avoid cutting the earth
as this will dull your pruner quickly.

• When supported at both ends. First, cut 1/3 down from the
top overbuck. Then make the finished cut by underbucking
the lower 2/3 to meet the first cut as shown below.
• When on a slope always stand on the uphill side of
the log. When "cutting through", to maintain complete
control reduce the cutting pressure near the end of the
cut without relaxing your grip on the pruner handles.
Don't let the chain contact the ground. After completing
the cut, wait for the pruner chain to stop before you
move the pruner. Always stop the motor before moving
from cut to cut.
