not in line with the blade. Kickback
could cause the saw to jump backwards,
but kickback forces can be controlled by
the operator, if proper precautions are
taken.
b) When blade is binding, or when inter-
rupting a cut for any reason, release
the trigger and hold the saw motion-
less in the material until the blade
comes to a complete stop. Never at-
tempt to remove the saw from the
work or pull the saw backward while
the blade is in motion or kickback
may occur. Investigate and take cor-
rective actions to eliminate the cause of
blade binding.
c) When restarting a saw in the work-
piece, centre the saw blade in the kerf
and check that saw teeth are are not
engaged into the material. If saw blade
is binding it may walk up or kickback from
the workpiece as the saw is restarted.
d) Support large panels to minimise the
risk of blade pinching and kickback.
Large panels tend to sag under their own
weight. Supports must be placed under
the panel on both sides, near the line of
cut and near the edge of the panel.
e) Do not use dull or damaged blades.
Unsharpened or improperly set blades
produce narrow kerf causing excessive
friction, blade binding an kickback.
f) Blade depth and bevel adjusting lock-
ing levers must be tight and secure
before making cut. If blade adjustment
shifts while cutting, it may cause binding
and kickback.
g) Use extra caution when making a
"plunge cut" into existing walls or
other blind areas. The protruding blade
may cut objects than can cause kick-
back.
5.4 Specifi c Safety Rules for
CSP 68-2 EB Circular Saws
a) Before each use, check if the retract-
ing blade guard closes properly. Do
not operate the saw if the retracting
blade guard does not move freely and
retract immediately. Never clamp or
tie the retracting blade guard in the
open position. If the saw is accidentally
dropped, the retracting blade guard can
be bent. Pull back the retracting blade
guard with the pull-back lever and ensure
that it moves freely and does not touch
the saw blade or other parts at any cut-
ting angles and depths-of-cut.
b) Check the spring function of the re-
tracting blade guard. If the retract-
ing blade guard and the spring do not
operate properly, have the machine
serviced before using. The retracting
blade guard may operate sluggish due
to damaged parts, gummy deposits or
build-up of chips/sawdust.
c) Only pull back the retracting blade
guard manually for special cuts, such
as "plunge and bevel cuts". Pull back
the retracting blade guard with the
pull-back lever and release it as soon
as the saw blade has penetrated the
work. For all other sawing jobs, the re-
tracting blade guard must operate auto-
matically.
d) Do not place down the saw on a work
bench or the ground without the re-
tracting blade guard covering the
saw blade. An unprotected, coasting
saw blade will move the saw in the op-
posite direction of the cut, cutting what-
ever is in its path. Pay attention to the
run-on period of the saw.
e) Use the matching riving knife for the
saw blade being worked with. The
riving knife must be wider than the thick-
ness of the blade back, but thinner than
the kerf width of the saw blade.
f) Adjust the riving knife as described
in the operating instructions. Incor-
rect width, position and alignment can be
the cause that the riving knife does not
effectively prevent kickback.
g) Always use the riving knife, except
when performing plunge cuts. After the
plunge cut, mount the riving knife again.
The riving knife interferes when performing
plunge cuts and can lead to kickback.
h) In order for the riving knife to be ef-
fective, it must be located in the cut.
For short cuts, the riving knife is ineffec-
tive for the prevention of kickback.
i) Do not operate the saw with a bent
riving knife. Even a minor malfunction
can lead to sluggish retraction of the re-
tracting blade guard.
