Safety instructions for saws with a pendulum blade
guard
Check lower guard for proper closing before each
N
use. Do not operate the saw if lower guard does not
move freely and close instantly. Never clamp or tie
the lower guard into the open position. If saw is
accidentally dropped, 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.
N
If the guard and the spring are not operating
properly, they must be serviced before use. Lower
guard may operate sluggishly due to damaged parts,
gummy deposits, or a build-up of debris.
Lower guard should be retracted manually only for
N
special cuts such as "plunge cuts" and "compound
cuts." Raise lower guard by retracting handle and
as soon as blade enters the material, the lower
guard must be released. For all other sawing, the lower
guard should operate automatically.
Always observe that the lower guard is covering
N
the blade before placing 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.
Additional safety instructions for all saws with riving
knife
Use the appropriate riving knife for the blade being
N
used. For the riving knife to work, it must be thicker than
the body of the blade but thinner than the tooth set of the
blade.
Adjust the riving knife as described in this
N
instruction manual. Incorrect spacing, positioning and
alignment can make the riving knife ineffective in
preventing kickback.
Always use the riving knife except when plunge
N
cutting. Riving knife must be replaced after plunge
cutting. Riving knife causes interference during plunge
cutting and can create kickback.
For the riving knife to work, it must be engaged in
N
the workpiece. The riving knife is ineffective in
preventing kickback during short cuts.
Do not operate the saw if riving knife is bent. Even a
N
light interference can slow the closing rate of a guard.
Additional safety instructions for circular saws
Wear ear protectors. Exposure to noise can cause
N
hearing loss.
Warning! Contact with or inhalation of dusts arising
N
from cutting applications may endanger the health of the
operator and possible bystanders. Wear a dust mask
specifically designed for protection against dust and
fumes and ensure that persons within or entering the
work area are also protectedical safety
Electrical safety
This tool is double insulated; therefore no earth wire
is required. Always check that the power supply
corresponds to the voltage on the rating plate.
Additional safety instructions for lasers
Warning! Laser radiation.
Do not look into the laser beam.
Do not view the laser beam directly with optical
instruments.
Refer to the laser product characteristics.
This laser complies with class 2 according to EN60825-1:1
N
1994+A11. Do not replace a laser diode with a different
type. If damaged, have the laser repaired by an authorised
repair agent.
Do not use the laser for any purpose other than projecting
N
laser lines.
An exposure of the eye to the beam of a class 2 laser is
N
considered safe for a maximum of 0.25 seconds.
Eyelid reflexes will normally provide adequate protection.
At distances over 1 m, the laser complies with class 1 and
thus is considered completely safe.
Never look into the laser beam directly and intentionally.
N
Do not use optical tools to view the laser beam.
N
Do not set up the tool at a position where the laser beam
N
can cross any person at head height.
Do not let children come near the laser.
