Chain Saw Basics (cont'd)
Site Preparation Tips
• Prepare the cutting area by clearing away brush,
branches, vines, etc.
• Remove any unnecessary tools and coil up excess
hydraulic hose.
• Survey the limb or branch to predict the direction or
path of fall. Ensure that no personnel are in that area.
• If working in a municipal area, plan the direction of
fall so that a limb doesn't fall into a roadway, strike a
nearby building, contact nearby power lines, etc.
• If the tree is on an incline, work uphill from the fall
path. A branch might tend to bounce or roll downhill.

Long-Reach Chain Saws (Foam-filled)
COMPRESSION AND TENSION
Any branch or log will have two forces acting on it—
compression and tension. As the branch or log is cut,
compression tends to push the two halves toward each
other. Tension tends to pull the two halves apart.
See the illustrations. A log or limb supported at both
ends has the compression on the top. A log or limb
supported at one end has the compression on the
bottom.
Make the first cut on the compression side. Cut through
approximately 1/3 of the log's diameter. Make the
second cut on the tension side. This will decrease the
likelihood that the saw will become pinched in the cut.
