Use Common Sense Maintain Secure Footing
D. LIMBING AND PRUNING
• Work slowly, keeping both hands firmly
gripped on the saw. Maintain secure footing and
balance.
• Watch out for springpoles. Use extreme caution
when cutting small size limbs. Slender material may
catch the saw chain and be whipped toward you or
pull you off balance.
• Be xdert for springback. Watch out for branches
that are bent or under pressure as you are cutting to
avoid being struck by the branch or the saw when the
tension in the wood fibers is released.
• Keep a clear work area. Frequently clear
branches out of the way to avoid tripping over them.
AWARNING
Never climb into a tree to limb dr pnme. Do not
stand on ladders, platforms, a log, or in any posi*
tidn which can cause you to lose your balance or
control of the saw.
1. LIMBING
a. Always limb a tree after it is cut doum. Only
then can limbing be done safely and properly.
b. Leave the larger limbs imderheath the
felled tree to support the tree as you work.
c. Start fd the base ofthe felled tree and work
toward the top, cutting branches and liinbs. Re­
move small limbs with one cut- Figure 26.
4- Keep the irpe between you and the chain.
Cut from the side of the tree opposite the brmich
you are cutting.
e. Remove larger, supporting branches with
the 1/3/2/3 cutting techniques described in
1.) Undercut 1/3 of the way through the log.
2i) Finish Twth an overcut.
£ Always use an overcut to cut small and
freely hanging limbs. Undercutting could
cause hmbs to faS and pinch the saw.
2. PRUNING
a. Limit pruning to limbs shoulder height or
below. Do not cut if branches are higher than
your shoulder. Get a professional to do the job.
h. Refer to Figure 27 for the pruning tech­
nique.
1. ) U ndercut 1/3 of the way through the limb near
the trunk of the tree.
2. ) Finish with an overcut farther out from the
trunk,
3. ) Keep out of the way of the falling limb.
4. ) Cut the stump flush near the trunk of the tree.
AWARNING
Be alert for and guard against kickback. Do not
allow the moving chain to contact any other
branebes or objects at the nose of the guide bar
when lithbing or pruning. Allowing such contact
can result in sermus iiqnry.
