Do not fell trees during periods of high wind or heavy precipitation. Wait until the hazardous
weather has ended.
When felling a tree, it is important that you heed the following warnings to prevent possible

Do not cut down trees having an extreme lean or large trees with rotten limbs, loose bark,
or hollow 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.
