Residual Risks; Aluminium Processing; Health Hazard By Dust; Intended Use - Festool HK 55 EQ Manual De Instrucciones

English
Wait until the power tool stops completely
–
until placing it down. The tool can become
entangled and lead to a loss of control of
the power tool.
– Do not use the machine for overhead work.
– Harmful/toxic dust may be produced dur­
ing your work (e.g. paint containing lead,
certain types of wood and metal). Inhaling
or coming into contact with this dust may
represent a hazard for operating personnel
or persons in the vicinity. Comply with the
safety regulations that apply in your coun­
try.
Wear a P2 dust mask to protect your
health.
Ensure that enclosed spaces are adequately
ventilated and, if necessary, connect a mobile
dust extractor.

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.

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 lubri­
cated with paraffin but thin-walled profiles
(up to 1/8" (3 mm)) can be sawed without
lubrication.

Health hazard by dust

WARNING! various dust created by pow­
er sanding, sawing, grinding, drilling and
other construction activities contains chemicals
known (to the State of California) to cause can­
cer, birth defects or other reproductive harm.
Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement
and other masonry products, and
• arsenic and chromium from chemically
treated lumber.
The risk from these exposures varies, depend­
ing on how often you do this type of work. To re­
duce your exposure to these chemicals: work in
a well ventilated area, and work with approved
safety equipment, such as dust masks that are
specially designed to filter out microscopic par­
ticles. Wash hands after handling.
WARNING
TO REDUCE THE RISK OF INJURY, USER
MUST READ INSTRUCTION MANUAL.
