Reducing Kickback; Sawing Techniques - Oregon PS750-091 Manual Original De Instrucciones

Reducing Kickback

Kickback can occur when the tip of the guide
bar touches an object or when the wood closes
in and pinches the saw chain inside of the cut .
Tip contact can kick the guide bar up and back
towards the operator .
WARNING: The danger of a kickback is
greatest when attempting to cut near or with
the guide bar tip . Always apply the saw as
flatly as possible in order avoid a loss of control
during operation .
Pinching the saw chain along the top of the
guide bar can push the bar rapidly towards the
operator . Either of these reactions may cause
a loss in control of the saw, increasing the
chances of serious personal injury .
Do not rely on the safety devices built into
the saw . Kickback is the result of tool misuse
and/or incorrect operating procedures . These
conditions can be minimized with the following
steps:
1 . Maintain a firm grip, with thumbs and
fingers encircling the pole saw handles .
Both hands should be on the saw with
your body and arms in a position to resist
kickback forces .
2 . Do not overreach and keep the work area
free from obstructions .
3 . Only use replacement bars and chains
specified by Senix . Replace dull blades as
necessary .
4 . Do not let the tip of the guide bar contact
any surfaces .
5 . Keep proper tension on the blade at
all times . Check the tension at regular
intervals .
6 . Cuts should only take place while the
chain is moving at full speed . Do not turn
the saw ON or OFF in the middle of a cut .
Use extreme caution when re-entering a
previous cut .
7 . Cut one branch at a time . Do not attempt
plunge or bore cuts . Watch for shifting logs
or other external forces that could close a
cut and pinch the chain .
8 . Make a precut on the opposite side of the
log to avoid the blade from being pinched
during operation as another safeguard
against kickback .

Important Safety Information

Sawing Techniques

WARNING: When removing branches, hold
the pole saw at an angle ranging from 0 to
60° in order to avoid being struck by a falling
branch . The saw should never be operated
directly above head .
• Saw off the lower branches on the tree
first . By doing so, it is easier for the cut
branches to fall to the ground .
• At the end of the cut, the weight of the
saw suddenly increases for the user since
it is no longer being supported by a branch .
There is a risk of losing control of the saw,
so make sure to stay alert during the entire
sawing operation .
• Only pull the saw out of a cut while the
saw is running . By doing so, you prevent the
chain from jamming in the wood .
• Do not saw with the tip of the guide bar . Do
not saw into the branch formations (where
the tree branches outwards) . This will
impede the tree's ability to heal .
• For sawing off smaller branches, place the
stop face of the saw on the branch . This
prevents unwanted movements of the saw
at the beginning of the cut . While applying
light pressure, guide the saw through the
branch from top to bottom .
• For sawing off larger branches, first make
a relief cut . Saw through 1/3 of the branch
diameter from the bottom to top using the
top side of the guide bar . Then saw from
top to bottom for the other 2/3 using the
bottom side of the guide bar .
• Saw off longer branches in sections in order
to maintain control over the location of
impact .
• When working on an incline, always stand
above or to the side of the branch being
sawed . Hold the tool as close as possible
to your body . By doing so, you maximize
your balance .
