Lower Guard Function - Metabo KS 165 Manual Original

c) When restarting a saw in the workpiece,
centre the saw blade in the kerf so that the saw
teeth are not engaged into the material. If a saw
blade binds, it may walk up or kickback from the
workpiece as the saw is restarted.
d) Support large panels to minimise the risk of
blade pinching and kickback. Large panels tend
to sag under their own weight. Supports must be
placed under the panel on both sides, near the line
of cut and near the edge of the panel.
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
the 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 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 (5) 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
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.
c) The lower guard may be retracted manually
only for special cuts such as "plunge cuts" and
"compound cuts".Raise the lower guard by the
retracting handle and as soon as the 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 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.
4.4 Additional Safety Instructions
Do not use sanding discs.
Pull the plug out of the plug socket before any
adjustments or servicing are performed.
Keep hands away from the rotating tool! Remove
chips and similar material only when the machine is
at a standstill.
Wear a suitable dust protection mask.
Wear ear protectors.
Wear protective goggles.
Press the spindle locking button (3) only when the
motor is at a standstill.
Do not reduce the speed of the saw blade by
pressing on the sides.
The lower guard must not be clamped in the pulled-
back position for sawing.
The lower 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 sure that the safety appliances, e.g.
the lower 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 sawely small workpieces.
During machining, the workpiece must be firmly
supported and secured against moving.
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.
Do not use saw blades made of high speed steel.
Do not use saw blades which do not comply with the
characteristics specifi ed in these instructions.
Never use the circular saw with its lower guard fixed
in the open position.
Never use the circular saw with its lower guard fixed
in the open position.
Never operate the circular saw with the saw blade
turned upward or to the side.
For model KS 165, the saw blades range should be
from 160 mm to 165 mm.
For model KS190, the saw blades range should be
from 184 mm to 190 mm.
Reducing dust exposure:
WARNING - Some dust created by power
sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to
cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
- Lead from lead-based paints,
