OPERATING INSTRUCTIONS
• Always cut with both feet on solid ground to prevent being pulled off balance.
• Do not cut above chest height as a saw held higher is difcult to control against kickback forces.
• Do not fell trees near electrical wires or buildings. Leave this operation for professionals.
• Cut only when visibility and light are adequate for you to see clearly.
When felling a tree, it is important that you heed the following warnings to prevent possible serious
injury.
• Do not cut down trees having an extreme lean or large trees with rotten limbs, loose bark, or hol-
low trunks. Have these trees pushed or dragged down with heavy equipment, then cut them up.
• Do not cut trees near electrical wires or buildings.
• Check the tree for damaged or dead branches that could fall and hit you during felling.
• Periodically glance at the top of the tree during the backcut to assure the tree is going to fall in
the desired direction.
• If the tree starts to fall in the wrong direction, or if the saw gets caught or hung up during the fall,
leave the saw and save yourself.

Hazardous conditions
WARNING
Do not fell trees during periods of high wind or heavy precipitation. Wait until the hazardous weather
has ended.
Removing buttress roots
A buttress root is a large root extending from the trunk
of the tree above the ground. Remove large buttress
roots prior to felling. Make the horizontal cut into the
buttress rst, followed by the vertical cut. Remove the
resulting loose section from the work area. Follow the
correct tree felling procedure as stated in Proper Pro-
cedure For Tree Felling after you have removed the
large buttress roots.
Proper procedure for tree felling
• Felling a tree — When bucking and felling opera-
tions are being performed by two or more persons
at the same time, the felling operation should be
separated from the bucking operation by a distance
of at least twice the height of the tree being felled.
Trees should not be felled in a manner that would
endanger any person, strike any utility line or cause
any property damage. If the tree does make contact
with any utility line, the utility company should be
notied immediately.
