Cutting with the Saw
IMPORTANT!
Always use full throttle while cutting!
Keep the chain sharp and let the saw
do the work! Forcing the saw into the
wood reduces cutting performance,
and can damage the saw through
overheating!
Felling Trees
Before Felling a Tree
1. Determine the direction of fall by
inspecting:
n Tree shape and angle of lean.
n Size and shape/placement of limbs.
n Location of nearby trees or other
obstacles.
n Condition of tree (damage, disease,
etc.).
n Prevailing wind direction.
2. Clear a safe work area around the
tree. Be alert for loose or dead limbs
overhead. Clear an appropriate
escape path approximately 45° from
the direction of fall.
3. Notify nearby workers of your
intentions!
