BASIC CUTTING PROCEDURE
This unit is designed for trimming small branches and limbs up to 7.5" (19 .1
cm) in diameter depending on the wood type. Practice cutting a few small
limbs using the following technique to get the "feel" of using the saw before you
begin a major sawing operation.
•
Take the proper stance in front of the tree with the saw OFF (Fig . 24).
•
Squeeze the trigger and let the chain accelerate to full speed before entering
the cut.
•
Keep the saw running the entire time you are cutting; maintain a steady
speed.
•
Allow the chain to cut for you; exert only light downward pressure. If you
force the cut, damage to the bar, chain, or unit can result.
•
PUSH and PULL - This reaction force is always opposite to the direction the
chain is moving when it is in contact with the wood. Thus, the operator must be
ready to control the PULL when cutting on the bottom edge of the bar, and
PUSH when cutting along the top edge.
•
Do not put pressure on the saw at the end of the cut.
PRUNING
Pruning is the process of trimming limbs from a live tree.
•
Remove long branches in several stages.
•
Cut lower branches first to allow the top branches more room to fall.
•
When pruning trees, it is important not to make the finishing cut next to the
main limb or trunk until you have cut off the farthest lying limb. This will reduce
the weight and prevent stripping the bark from the main member.
