en ENGLISH
e) Do not use dull or damaged blades. Unsharp-
ened or improperly set blades produce narrow kerf
causing excessive friction, blade binding and kick-
back.
f) Blade depth and bevel adjusting locking
levers must be tight and secure before making
cut. If blade adjustment shifts while cutting, it may
cause binding and kickback.
g) Use extra caution when making a "plunge
cut" into existing walls or other blind areas. The
protruding blade may cut objects that can cause
kickback.
4.3 Lower guard function
a) Check lower guard for proper closing before
each 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 posi-
tion. 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.
b) Check the operation of the lower guard
spring. If the guard and the spring are not oper-
ating properly, they must be serviced before
use. Lower guard may operate sluggishly due to
damaged parts, gummy deposits, or a build-up of
debris.
c) Lower guard may be retracted manually only
for special cuts, such as plunge cuts and
compound cuts. Raise lower guard by retracting
handle (10) and as soon as blade enters the mate-
rial, the lower guard must be released. For all other
sawing, the lower guard should operate automati-
cally.
d) Always observe that the lower guard is
covering 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.
4.4 Additional Safety Instructions
Do not use grinding wheels.
Pull the plug out of the plug socket before carrying
out any adjustments or servicing.
Keep hands away from the rotating tool! Remove
chips and similar material only when the machine is
at a standstill.
Wear ear protectors.
Wear protective goggles.
Press the spindle locking button only when the
motor is at a standstill.
Do not reduce the speed of the saw blade by
pressing on the sides.
The movable safety guard must not be clamped in
the pulled-back position for sawing.
10
The movable safety guard must move freely, auto-
matically, easily and exactly back into its end posi-
tion.
When sawing materials that generate large quanti-
ties of dust, the machine must be cleaned regularly.
Make sure that the safety appliances, e.g. the
movable safety guard, are in perfect working order.
Materials that generate dusts or vapours that may
be harmful to health (e.g. asbestos) must not be
processed.
Check the workpiece for foreign bodies. When
working, always make sure that no nails or other
similar materials are being sawed into.
If the saw blade blocks, turn the motor off immedi-
ately.
Do not try to saw extremely small workpieces.
During machining, the workpiece must be firmly
supported and secured against moving.
Dust from material such as paint containing lead,
some wood species, minerals and metal may be
harmful. Contact with or inhalation of the dust may
cause allergic reactions and/or respiratory diseases
to the operator or bystanders.
Certain kinds of dust are classified as carcinogenic,
such as oak and beech dust, especially in
conjunction with additives for wood conditioning
(chromate, wood preservative). Material containing
asbestos must only be treated by specialists.
- Use a dust extraction device where possible.
- To achieve a high level of dust collection, use a
suitable Metabo vacuum cleaner together with this
tool.
- The work place must be well ventilated.
- The use of a dust mask of filter class P2 is recom-
mended.
Follow national requirements for the materials you
want to work with.
Use a saw blade that is suitable for the material
being sawn.
Clean gummy or glue-contaminated saw
blades. Contaminated saw blades cause
increased friction, jamming of the saw blade and
increase the risk of back-kicks.
Avoid overheating of the saw tooth tips. Avoid
melting of the material when sawing plastic.
Use a saw blade that is suitable for the material
being sawn.
