Aluminium Processing; Emission Levels - Festool TS 75 EBQ Manual De Instrucciones

Use extra caution when sawing into exist­
–
ing walls or other blind areas. The pro­
truding blade may cut objects that can
cause kickback.
Lower guard function
– Check the lower guard for proper closing
before each use. Do not operate the saw if
the lower guard does not move freely and
close instantly. Never clamp or tie the
lower guard into the open position. If the
saw is accidentally dropped, the lower
guard may be bent. Raise the lower guard
with the retracting handle and make sure it
moves freely and does not touch the blade
or any other part, in all angles and depths
of cut.
– Check the operation of the lower guard
spring. If the guard and the spring are not
operating properly, they must be serviced
before use. Lower guard may operate slug­
gishly due to damaged parts, gummy de­
posits, or a build-up of debris.
– 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.
Riving knife function
Use the appropriate saw blade for the riv­
–
ing knife. For the riving knife to function,
the body of the blade must be thinner than
the riving knife and the cutting width of the
blade must be wider than the thickness of
the riving knife.
Adjust the riving knife as described in this
–
instruction manual. Incorrect spacing,posi­
tioning and alignment can make the riving
knife ineffective in preventing kickback.
– For the riving knife to work, it must be en­
gaged in the workpiece. The riving knife is
ineffective in preventing kickback during
short cuts.
Do not operate the saw if the riving knife is
–
bent. Even a light interference can slow
the even a light interference can slow the
closing rate of a guard.

Aluminium processing

When sawing aluminium, the following
measures must be taken for safety reasons:
– Connect the power tool to a suitable dust
extractor.
– Regularly clean dust deposits from the mo­
tor housing on the power tool.
– Use an aluminium saw blade.
Wear protective goggles.
– When sawing panels, they must be lubrica­
ted with petroleum but thin-walled profiles
(up to 3 mm) can be sawed without lubrica­
tion.

Emission levels

The levels determined in accordance with EN
62841 are typically:
Sound pressure level
Sound power level
Uncertainty
CAUTION
Noise generated when working
Risk of damage to hearing
► Use ear protection.
Vibration emission level a
three directions) and uncertainty K measured in
accordance with EN 62841:
Sawing wood
Sawing metal
The specified emission levels (vibration, noise)
– 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.
