e) Do not use dull or damaged blades. Unsharpened
or improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
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 sawing into existing
walls or other blind areas. The protruding blade may
cut objects that can cause kickback.
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 position.
If the saw is accidentally dropped, lower safety guard
may be bent. Raise the lower guard with the retracting
handle (25)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 safety guard
spring. If the safety guard and the spring are not
operating properly, they must be serviced before
use. Lower safety 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 (25) and as soon as blade enters the
material, the lower guard must be released. For all
other sawing, the lower guard should operate
automatically.
d) Always observe that the lower safety 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.
Do not use grinding wheels.
Keep hands away from the rotating tool! Remove chips
and similar material only with the machine at 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.
The movable safety guard must move freely,
automatically, easily and exactly back into its end
position.
When sawing materials that generate large quantities of
dust, the machine must be cleaned regularly. Make
12
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 immediately.
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.
- Where the use of a dust extraction device is
possible it shall be used.
- 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
recommended.
Follow national requirements for the materials you want
to work with.
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.
Protect battery packs from water and
moisture!
Do not use faulty or deformed battery packs!
Do not expose battery packs to naked flame!
Do not open battery packs!
Do not touch or short-circuit battery packs!
Remove the battery pack from the machine when
not in use.
Remove the battery pack from the machine
before any adjustment or maintenance is
carried out.
Before fitting the battery pack, make sure that
the machine is switched off.
Slightly acidic, flammable fluid may leak from
defective Li-ion battery packs!
