Causes And Operator Prevention Of Kickback - Poulan Pro PPB40PS Manuel D'instructions

WARNING: (PROPOSITION 65)
Some dust created by power sanding, sawing,
grinding, drilling, and other construction
activities contains chemicals known to cause
cancer, birth defects or other reproductive
harm. Some examples of these chemicals
are:
• Lead from lead-based paints
• Crystalline silica from bricks and cement
and other masonry products, and
• Arsenic and chromium from chemically
treated lumber.
Your risk of exposure to these chemicals
varies depending on how often you do this
type of work. To reduce your exposure to
these chemicals, work in a well-ventilated
area, and work with approved safety
equipment, such as dust masks that are
specially designed to filter out microscopic
particles.
SAVE THESE INSTRUCTIONS
KICKBACK
Kickback may occur when the nose or tip of
the guide bar touches an object, or when the
wood closes in and pinches the saw chain in
the cut.
Tip contact in some cases may cause a
sudden reverse reaction, kicking the guide
bar up and back towards the operator.
Pinching the saw chain along the top of the
guide bar may push the guide bar rapidly
back towards the operator.
Either of these reactions may cause you to
lose control of the saw which could result in
serious personal injury. Do not rely exclusively
upon the safety devices built into your saw. As
a polesaw user, you should take several
steps to keep your cutting jobs free from
accident or injury.
SAFETY RULES
CAUSES AND OPERATOR PREVENTION
OF KICKBACK
• Maintain a firm grip, with thumbs and
fingers encircling the polesaw handles,
with both hands on the saw and
position your body and arm to allow
you to resist kickback forces. Kickback
forces can be controlled by the operator, if
proper precautions are taken. Do not let go
of the polesaw.
• Only use replacement bars and chains
specified by the manufacturer. Incorrect
replacement bars and chains may cause
chain breakage and/or kickback.
• Follow the manufacturer's sharpening
and maintenance instructions for the
saw chain. Decreasing the depth gauge
height can lead to increased kickback.
• Push and Pull — This reaction force is
always opposite to the direction the chain
is moving where contact is made with the
wood. Thus, the operator must be ready
to control the PULL when cutting on the
bottom edge of the bar, and the PUSH
when cutting along the top edge.
