in the machinery or brush.

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!

WARNING!

NEVER operate with a loose saw chain! NEVER operate the saw if any component parts are damaged, loose, or missing!

Felling Trees

WARNING!

When felling, keep at least 2 tree lengths away from your fellow workers.

Before Felling a Tree

1.Determine the direction of fall by inspecting:

a.Tree shape and angle of lean.

b.Size and shape/placement of limbs.

c.Location of nearby trees or other obstacles.

d.Condition of tree (damage, disease, etc.).

e.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 approxi- mately 45° from the direction of fall.

3.Notify nearby workers of your intentions!

WARNING!

Diseased, damaged, or other- wise unbalanced trees can fall unpre- dictably during felling, and should be left to an experienced timber faller!

Felling Small Trees

(Under 6” (15cm) diameter)

1.Determine the direction of fall. If uncertain as to the direction of fall, use the procedure “Felling Large Trees” as outlined in the next section.

2.Engage the bumper spike against the trunk of the tree and start to cut on the side of the tree away from the fall. Make a single cut all the way through the tree.

3.When the tree begins to fall, stop the saw, and put it down on the ground.

4.Use your retreat path to exit the area quickly.
