cut for any reason, release the trigger and hold
the saw motionless in the material until the
blade comes to a complete stop. Never attempt
to remove the saw from the work or pull the saw
backward while the blade is in motion or kick-
back may occur. Investigate and take corrective
actions to eliminate the cause of blade binding.
c. When restarting a saw in the workpiece, centre
the saw blade in the kerf and check that saw
teeth are not engaged into the material. If saw
blade is binding, 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. Unsharp-
ened 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.
Guard function
a. Check guard for proper closing before each use.
Do not operate the saw if guard does not move
freely and enclose the blade instantly. Never
clamp or tie the guard so that the blade is ex-
posed.
If saw is accidentally dropped, guard may
be bent. Check to make sure that guard moves
freely and does not touch the blade or any other
part, in all angles and depths of cut.
b. Check the operation and condition of the guard
return spring. If the guard and the spring are
not operating properly, they must be serviced
before use.
Guard may operate sluggishly due to
damaged parts, gummy deposits, or a build-up of
debris.
c. Assure that the base plate of the saw will not
shift while performing the “plunge cut” when
the blade bevel setting is not at 90°.
Blade shift-
ing sideways will cause binding and likely kick
back.
d. Always observe that the 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.
Function of the guide wedge [5-4]
a. Use the correct saw blade for the guide wedge.
To ensure that the guide wedge functions proper-
ly, make sure the blade core of the saw blade is
thinner than the guide wedge and that the tooth
width is greater than the thickness of the guide
wedge.
b. Do not operate the saw if the guide wedge is
bent. Even the slightest problem can cause the
protective cover to close more slowly.
5.3 Emission levels
Levels determined in accordance with EN 60745 are
typically:
Vibration emission value a
h
(vector sum for three
directions) and uncertainty K measured in accor-
dance with EN 60745:
The specified emissions values (vibration, noise)
– are used to compare machines.
– They are also used for making preliminary esti-
mates regarding vibration and noise loads during
operation.
– They represent the primary applications of the
power tool.
Increase possible for other applications, with other
insertion tools or if not maintained adequately. Take
note of idling and downtimes of machine!
5.4 Aluminium processing
When processing aluminium, the following
measures must be taken for safety reasons:
Sound pressure level L
PA
= 88,5 dB(A)
Noise level L
WA
= 99,5 dB(A)
Measuring uncertainty allow-
ance K = 3 dB
