Porter-Cable PCC661 Instruction Manual page 6

• Lead from lead-based paints,
crystalline silica from bricks and cement
and other masonry products, and arsenic
and chromium from chemically-treated
lumber (CCA).
Your risk from these exposures 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 those dust
masks that are specially designed to
filter out microscopic particles.
• Avoid prolonged contact with
dust from power sanding, sawing,
grinding, drilling, and other
construction activities. Wear
protective clothing and wash
exposed areas with soap and water.
Allowing dust to get into your mouth,
eyes, or lay on the skin may promote
absorption of harmful chemicals.
WARNING:
generate and/or disburse dust, which may
cause serious and permanent respiratory
or other injury. Always use NIOSH/OSHA
approved respiratory protection
appropriate for the dust exposure. Direct
particles away from face and body.
Always operate tool in well-ventilated area
and provide for proper dust removal. Use
dust collection system wherever possible.

Use of this tool can
To Reduce the Risk of
kickback
• Keep a firm grip on saw with both hands
at all times.
• Stay alert – exercise control.
• Support long overhanging materials. As
the material is cut and weakens, it will
sag, causing a pinched blade.
• Support large panels as shown (fig. e).
Material supported only at the ends (fig.
d) will lead to blade pinching.
• Avoid sawing overhead. Material can sag
and will pinch blade.
• Insure that the material to be cut is
clamped (figure G) and solidly supported
and balanced on a strong, stable and
level work surface. Support the work so
that the wide portion of the saw shoe is on
the portion of the material that doesn't fall
after the cut is made. Never hold cut off
piece by hand (figure f)
• Keep blades sharp and clean.
• Use fence or straight edge guide when
ripping. Be careful as the cut off strip can
sag or twist, closing the cut and pinching
the blade, leading to KICKBACK.
• Don't force tool. Wood variables such as
knots, hardness, toughness, wetness,
pressure treated and freshly cut green
lumber can heavily load the saw which
can lead to stalling. Push the saw slower
when this occurs.
• Don't remove saw from work during a cut
while the blade is moving.
• Allow saw to reach full speed before
blade contacts material to be cut.
Starting the saw with the blade against
the work or pushed forward into cut can
lead to stalling or sudden backward
movement of saw.
• Never attempt to lift saw when making
a bevel cut. This leads to blade binding
and stalling.
• Always secure work to prevent
workpiece movement during cut.
• Do not try to force saw back on line if
your cut begins to go off line. This can
cause KICKBACK. Stop saw and allow
blade to coast down to a stop. Withdraw
from cut and start a new cut on the line.
• Set depth adjustment of saw such that
one tooth of the blade projects below the
workpiece as shown in (figure I).
• Do not back up a rotating blade in the
cut. Twisting the saw can cause the back
edge of the blade to dig into the material,
climb out of the work and run back toward
the operator.
• Avoid cutting nails. Inspect for and
remove all nails from lumber before
cutting.
