Safety
3.1
Explanation of symbols
You will find this symbol all information relating to
health and safety in this Operator’s Guide where
there is a danger to life and limb. Please read this
information carefully and take particular care in
these cases. Please pass the safety information on
to other users. As well as the information in this
guide the generally-applicable safety and accident
prevention instructions must be noted.

Operational safety details
All machine tools, particularly woodworking
machines with manual feed involve a certain risk
when handled incorrectly. Therefore always
observe the safety information that is summarised
in this chapter as well as government and other
industrial safety regulations (e.g. accident
prevention rules)!
–
Never operate the machine without the
protective devices intended for the specific
work cycle (also refer to “Working safely with
the sliding table saw – Working examples”),
and do not make any changes that might impair
safety.
–
Before all work, make sure that the protective
and working devices are securely fitted and are
not damaged.
–
Before changing a tool, rectifying any faults and
carrying out repairs, make sure that the
machine cannot be turned on accidentally, for
example by padlocking the main switch.
–
Only use saw blades and grooving tools that
comply with European standard EN 847-1.
–
Only fit saw blades with the dimensions descri-
bed in table 1. The diameter of the mounting
hole must always measure 30 mm. Loose inter-
mediate rings are not allowed to be used.
–
Select the rotational speed so that the
maximum permissible rpm specified for the tool
is not exceeded when using tungsten carbide
tipped saw blades or grooving cutters.
–
HSS saw blades and cracked or deformed saw
blades are not allowed to be used.
–
Always wear tight-fitting working clothes and do
not wear rings, bracelets or watches.
–
Make sure that the workplace is uncluttered,
slip-proof and well lit.
–
Do not cut workpieces that are too large or too
small for the machine to handle.
–
When working at the machine, always stand to
the side of the saw blade outside a possible
kick-back area (area direcly in front of the saw
blade).
–
Remove any loose parts from the vicinity of the
saw blade before switching on the machine.
–
Only start cutting when the saw blade has
reached its full rotational speed.
–
Always use the top safety hood!
–
Adjust the height of the top safety hood to the
thickness of the workpiece to be cut.
–
Always use the riving knife except for insert
cuts. The riving knife must not be thicker than
the cutting line width or thinner than the main
blade. Adjust it so that it is at a distance of most
8 mm from the gear rim. The guide slot must be
13 + 0.5 mm wide. The riving knives supplied
with the machine cover the entire range of dia-
meters for the saw blades that are allowed to be
used – from 250 mm to 400 mm. With respect
to their thickness, they match the cutting line
widths of commercially available tungsten car-
bide tipped saw blades. If other saw blades,
e.g. made of chrome vanadium (CV), are used,
select a riving knife thickness that lies between
the cutting line width and the main blade thick-
ness. Such riving knifes can be obtained from
the trade or directly from ALTENDORF.
–
Use an anti-kick device for insert cuts, e.g. the
front of the clamping shoe. Fix this in the sliding
table groove, ensuring that the sliding table is
locked with its interlock to prevent movement.
Following insert cutting, refit the riving knife and
the top safety hood immediately.
–
Always guide the workpiece safely and use the
appropriate stops/fences (rip fence, fence
scale, crosscut fence on cross-slides, cross
stop) .
–
Use a push stick when cutting narrow
workpieces (less than 120 mm) at the rip fence.
–
Only do crosscuts when the cross-slide is fixed
to the sliding table. Make sure that small cut-off
workpieces cannot be taken up by the gear rim
and kick out, for example by using a deflection
wedge.
–
Crosscuts and longitudinal cuts in round wood
are not allowed with the standard feeding aids
or fences/stops.
–
For trimming, use the clamping shoe fixed to
the sliding table to hold down the workpiece.
–
When using a feeding unit, use at least the
riving knife as an anti-kick device.
–
Replace worn-out table strips immediately.
