SAFETY INFORMATION FOR CIRCULAR HANDSAWS
– Apart from these machine-specific safety instructions, also observe the
safety instructions for the circular handsaw used.
– Always use circular handsaws with a riving knife, max. saw blade diameter of
200 mm and max. cutting depth of 70 mm.
– Do not use saws with base plate dimensions greater than the maximum val-
ues indicated (Fig. 2.29).
– Support long workpieces on the receiving side so that they lie flat; e.g. with a
wolfcraft roller trestle (art. no. 6102300).
– Avoid overloading the circular handsaw.
– Do not use grinding wheels.
– Use only recommended saw blades and select them depending on the mater-
ial to be sawn.
SAFETY INFORMATION FOR CIRCULAR BENCH SAWS
Safety information relevant to the protective cover
– Leave protective covers mounted. Protective covers must be in proper
working order and correctly mounted. Loose, damaged or poorly function-
ing protective covers must be repaired or replaced.
– Always use the saw blade protective cover and the riving knife for
through cuts. The protective cover and other safety devices reduce the risk of
injuries for through-cutting where the blade saws through the entire thickness
of the workpiece.
– After completing operations which required removing the protective
cover or the riving knife, immediately reinstall the protective system. The
protective cover and riving knife reduce the risk of injuries.
– CAUTION The machine table must not be used for cutting joints, making
slits or slicing wood during timber handling.
– Before switching on the power tool, make sure that the saw blade is not
touching the protective cover, the riving knife or the workpiece. Acci-
dental contact between these components and the saw blade can result in an
unsafe situation.
– Adjust the riving knife as described in these operating instructions. In-
correct spacing, position and alignment may result in the riving knife failing
to effectively prevent kickback.
– In order for the riving knife to be able to work, it must act on the work-
piece. The riving knife will have no effect for cuts in workpieces that are too
short to allow the riving knife to engage. Under these conditions, the riving
knife is not able to prevent kickback.
– Use the appropriate saw blade for the riving knife. In order for the riving
knife to work correctly, the saw blade diameter must match the relevant riving
knife, the body of the saw blade must be thinner than the riving knife and the
tooth width must be greater than the riving knife thickness.
Safety information for saw operations
– DANGER: Do not place your fingers or hands near the saw blade or in
the sawing area. A moment of inattention or a slip could result in your hand
being propelled towards the saw blade and result in serious injuries.
– Feed the workpiece to the saw blade against the direction of rotation
only. Feeding the workpiece in the same direction as the saw blade's direc-
tion of rotation above the machine table can result in the workpiece and your
hand being drawn into the saw blade.
– Never use the mitre stop to feed the workpiece when making rip cuts
and never additionally use the parallel guide as a length stop when
making cross cuts with the mitre stop. Simultaneously guiding the work-
piece using the parallel guide and the mitre stop increases the probability of
the saw blade binding and kickback occurring.
– When making rip cuts, always exert the workpiece feeding force
between the stop rail and saw blade. Use a push stick if the distance
between the stop rail and saw blade is less than 150 mm, and a push
block if the distance is less than 50 mm. These work aids ensure that your
hand remains a safe distance from the saw blade.
– Only use the push stick supplied by the manufacturer or another push
stick manufactured according to instructions. The push stick ensures suffi-
cient distance between your hand and the saw blade.
– Never use a damaged or partially sawn-off push stick. A damaged push
stick can break and result in your hand coming into contact with the saw
blade.
– Do not work "freehand". Always use the parallel guide or the mitre stop
to position and guide the workpiece. "Freehand" means supporting or
guiding the workpiece using the hands instead of using a parallel guide or
mitre stop. Freehand sawing will result in misalignment, binding and kick-
back.
– Never reach around or over a rotating saw blade. Reaching for a work-
piece can result in unintentional contact with a rotating saw blade.
– • Support long and/or wide workpieces at the back and/or side of the
machine table to keep them horizontal. Long and/or wide workpieces tend
to tilt at the edge of the machine table; this results in loss of control, saw
blade binding and kickback.
– Feed the workpiece at an even pace. Do not bend or turn the workpiece.
If the saw blade jams, switch off the power tool immediately, pull out
the mains plug and remove the cause of the jam. Saw blade binding at
the workpiece can result in kickback or a blocked motor.
– Do not clear away cut-off material while the saw is running. Cut-off ma-
terial can settle between the saw blade and stop rail (fence) or in the protect-
ive cover and can draw your finger into the saw blade if you attempt to clear
it away. Switch off the saw and wait until the saw blade has come to a stop
before clearing the material.
– CAUTION Do not process workpieces less than 2 mm in thickness.
Kickback − Causes and related safety information
Kickback is a sudden reaction of the workpiece due to a pinched, jammed saw
blade or misaligned line of cut in the workpiece with respect to the saw blade or
when a part of the workpiece binds between the saw blade and the parallel guide
or other fixed object. In most cases of kickback, the workpiece is lifted from the
machine table by the rear section of the saw blade and is propelled towards the
user. Kickback is the result of misuse of the circular table saw or incorrect opera-
tion. It can be prevented through suitable precautions, as described below.
– Never stand in a direct line with the saw blade. Always keep stay on the
same side of the saw blade as the stop rail. Kickback can cause the work-
piece to be flung at high speed towards people standing in front of and in
line with the saw blade.
– Never reach over or behind the saw blade to pull or support the work-
piece. This can result in unintentional contact with the saw blade or kickback
can result in your fingers being drawn into the saw blade.
– Never hold and push the workpiece being sawn against the rotating
saw blade. Pushing the workpiece being sawn against the saw blade will res-
ult in binding and kickback.
– Align the stop rail parallel to the saw blade. An unaligned stop rail will
push the workpiece against the saw blade and cause kickback.
– CAUTION The machine table must not be used for cutting joints, making
slits or slicing wood during timber handling.
– Exercise particular care when sawing in non-visible areas of assembled
workpieces. The protruding saw blade may cut into objects that can cause
kickback.
– Support large boards to reduce the risk of kickback due to a jammed
saw blade. Large boards can bend under their own weight. Boards must be
supported wherever they project past the table surface.
– Exercise particular care when sawing workpieces that are twisted, knot-
ted or warped or that do not have a straight edge for guiding with a
mitre stop or along a stop rail. A twisted, knotted or warped workpiece is
unstable and will result in misalignment of the kerf with the saw blade, bind-
ing and kickback.
– Never saw several workpieces stacked one on top of each other or one
behind the other. The saw blade could pick up one or more parts and cause
kickback.
– If you want to restart a saw whose blade is positioned in the workpiece,
centre the saw blade in the kerf in such a way that the saw teeth are
not engaged in the workpiece. If the saw blade binds, it can lift the work-
piece and cause kickback when the saw is restarted.
– Keep the saw blades clean, sharp and ensure the tooth set is adequate.
Never use warped saw blades or saw blades with cracked or broken
teeth. Sharp saw blades with correct tooth set reduce binding, blocking and
kickback.
