Limbing And Pruning - Scotts LPS40820S Manual Del Operario

WARNING: Kickback may occur when the moving chain contacts an
object at the upper portion of the tip of the guide bar or when the wood
closes in and pinches the chain saw in the cut. Contact at the upper
portion of the tip of the guide bar can cause the chain to dig into the
object and stop the chain for an instant. The result is a lightening fast,
reverse reaction which kicks the guide bar up and back toward the
operator. If the chain saw is pinched along the top of the guide bar, the
guide bar can be driven rapidly back toward the operator. Either of
these reactions can cause loss of saw control which can result in
serious injury. Do not rely exclusively upon the safety devices built into
the saw. As a chain saw user, you should take several steps to keep
your cutting jobs free from accident or injury.
The following precautions should be followed to minimize
kickback:
1. Always grip the pole and handle firmly with both hands. Hold the
saw firmly with both hands when the unit is running. Place your
right hand on the rear handle and your left hand on the pole shaft
with your thumbs and fingers encircling the pole saw handle and
shaft. A firm grip together with a stiff left arm will help you maintain
control of the saw if kickback occurs.
2. Make sure that the area in which you are cutting is free from
obstructions. Do not let the nose of the guide bar contact a log,
branch, fence or any other obstruction that could be hit while you
are operating the saw.
BASIC CUTTING PROCEDURE
See figure 8-9
Keep the tree between you and the chain while limbing.
Cut from side of tree opposite branch you are cutting.
Do not cut from a ladder; this is extremely dangerous. Leave this
operation for professionals.
Do not use the pole saw for felling or bucking,
To prevent electrocution, do not operate within 50 ft. of overhead
electrical lines,.
Follow the steps below to prevent damage to tree or shrub bark. Do not
use a back-and-forth sawing motion,
Do not make the flush cut next to the main limb or trunk until you have
cut of the limb further out to reduce the weight.
Following proper cutting procedures will prevent stripping bark
from the main member.
Make a shallow first cut (1/4 of limb diameter) on the underside of the
limb close to the main limb or trunk,
Make a second cut from the top side of the limb outboard from the first
cut. Continue the cut
through the limb until
the limb separates
from the tree. Be
prepared to balance
the weight of the tool
when the limb falls.
Make a final cut
close to the trunk.
For second and final cuts, (from top of limb or branch), hold front cutting
guide against the limb being cut. This will help steady the limb and
make it easier to cut. Allow the chain to cut for you; exert only light
downward pressure. If you force the cut, damage to the bar, chain, or
motor can result.

3. Always cut with the unit running at full speed. Fully squeeze the
throttle trigger and maintain a steady cutting speed.
4. Wear non-slip gloves for maximum grip protection.
Cut lower branches first to allow the top branches more room to fall.
Work slowly, keeping both hands on the saw with a firm grip.
Maintain secure footing and balance.
WARNING: To protect yourself from electrocution, maintain a min of 50ft
(15m) from over head electrical lines.
Keep bystanders at least 50ft. away.
Release the trigger as soon as the cut is completed. Failure to follow
proper cutting procedures will result in the bar and chain binding and
becoming pinched or trapped in the limb.
If this should happen:
Stop the motor and remove the battery pack.
If the limb can be reached from the ground, lift the limb while holding the
saw. This should release the "PINCH" and free the saw.
If the saw is still trapped, call a professional for assistance.

LIMBING AND PRUNING

See figure 10
Fig.10
This unit is designed for
trimming small branches
and limbs up to 6 inches
(15cm) in diameter.
For best results, observe
the following precautions.
Plan the cut carefully. Be
aware of the direction in
which the branch will fall.
Branches may fall in
unexpected directions. Do
not stand directly under the branch being cut.
The most typical cutting application is to position the unit at an angle of
60° or less, depending on the specific situation, as shown. As the angle
of the pole saw shaft to ground increases, the difficulty of making the
first cut (from the underside of the limb) increases.
Remove long branched in several stages.
