Residual Risks; Aluminium Processing - Festool HK 55 EBQ Manual De Instrucciones

The lower guard may be retracted man­
–
ually only for special cuts such as "plunge
cuts" and "compound cuts". Raise the low­
er guard by the retracting handle and as
soon as the blade enters the material, the
lower guard must be released. For all oth­
er sawing, the lower guard should operate
automatically.
– Always observe that the lower guard is
covering the blade before placing the saw
down on bench or floor. An unprotected,
coasting blade will cause the saw to walk
backwards, cutting whatever is in its path.
Be aware of the time it takes for the blade
to stop after switch is released.
Function of the guide wedge [1-5]
Use the correct saw blade for the guide
–
wedge, where possible. The function of the
guide wedge is restricted if using saw
blades with a thicker blade core. To en­
sure that the guide wedge functions prop­
erly, make sure the blade core of the saw
blade is thinner than the guide wedge and
that the tooth width is greater than the
thickness of the guide wedge. Expect in­
creased risk of kickback when using a
thicker saw blade.
Do not operate the saw if the guide wedge
–
is bent. Even the slightest problem can
cause the guard to close more slowly.
Further safety instructions
This power tool cannot be installed in a
–
work bench. The power tool may become
unsafe and cause serious accidents if in­
stalled in benches from other manufactur­
ers or self-manufactured work benches.
– Never place your hands into the chip ejec­
tor. You may injure yourself on rotating
parts.
Use appropriate detection devices to look
–
for any hidden supply lines or consult your
local utility company. If the insertion tool
makes contact with live cables, it can result
in fire and electric shock. Damage to a gas
pipe can lead to an explosion. Penetration
of a water pipe can result in damage to
property.
Wait until the power tool has come to a
–
complete halt before placing it down. The
insertion tool can get caught 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 or metals). Contact
with or inhalation of this dust may pose a
risk for the operating personnel or persons
in the vicinity. Comply with the safety regu­
lations that apply in your country.
– Wear suitable breathing protection to pro­
tect your health. In enclosed spaces, en­
sure that there is sufficient ventilation and
connect a mobile dust extractor.
–
Wear suitable personal protective equip­
ment: Ear protection, safety goggles, a dust
mask for work that generates dust.
– Check whether there are any signs of
damage to the housing components, such
as cracks or stress whitening. Have any
damaged components repaired before us­
ing the power tool.
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.

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.
