Residual Risks; Aluminium Processing; Emission Levels; Intended Use - Festool HK 85 EB Manual De Instrucciones

English
Ensure that enclosed spaces are adequately
ventilated and, if necessary, connect a mobile
dust extractor.
Only for AS/NZS: The tool shall always be
–
supplied via residual current device with a
rated residual current of 30 mA or less.

Residual risks

In spite of compliance with all relevant design
regulations, hazzards while operating the ma­
chine still occur e.g.:
– Touching the saw blade in the area of the
front opening below the saw table,
– Touching the parts of the saw blade that
protrude below the saw table while cutting,
– Touching rotating parts from left and right
sides: saw blade, clamping flange, flange
screw.,
– Kickback of machine due to jamming in the
workpiece,
– Touching live parts when the casing is
opened and the mains plug is in the socket,
– the flying off of parts,
– the flying off of machine parts from a dam­
aged machine,
– noise emission,
– dust emission.
2.6

Aluminium processing

When sawing aluminium, the following
measures must be taken for safety reasons:
– Install an upstream residual-current circuit
breaker (FIG, PRCD).
– Connect the machine to a suitable dust ex­
tractor.
– Regularly remove dust deposits from the
motor housing.
– Use an aluminium saw blade.
– Close the viewing window/chipguard.
Wear protective goggles.
– When sawing panels, they must be lubrica­
ted with paraffin but thin-walled profiles
(up to 3 mm) can be sawed without lubrica­
tion.

CAUTION
Noise generated when working
Risk of damage to hearing
► Use ear protection.
Sawing wood
Sawing metal
are used to compare machines.
They are also used for making preliminary
estimates regarding vibration and noise
load during operation.
They represent the primary applications of
the power tool.
CAUTION
The emission values may deviate from the
specified values. This is dependent on how
the tool is used and the type of workpiece
being machined.
► The actual load during the entire operating
cycle must be evaluated.
► Depending on the actual load, suitable pro­
tective measures must be defined in order
to protect the operator.
