ENG
Wear safety goggles when working with the
machine.
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.
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 work pieces.
During machining, the workpiece must be firmly
supported and secured against moving.
Do not use sanding discs.
The dust created when working is often harmful to
health (e.g. when working with oak and beech,
being materials which contain harmful substances)
and should not be allowed to enter your body. Use
a dust extractor and in addition wear a suitable
dust protection mask. Thoroughly remove any
dust deposits, e.g. by vacuum cleaning.
DANGER:
a) Keep hand away from cutting area and the
blade. Keep your second hand on auxiliary
handle, or motor housing. If both hands are
holding the saw, they cannot be cut by the blade.
b) Do not reach underneath the workpiece. The
guard cannot protect you from the blade below the
workpiece.
c) Adjust the cutting depth to the thickness of
the workpiece. Less than a full tooth of the blade
teeth should be visible below the workpiece.
d) Never hold piece being cut in your hands or
across your leg. Secure the workpiece to a
stable platform. It is important to support the work
properly to minimize body exposure, blade binding,
or loss of control.
e) Hold power tool by insulated gripping
surfaces when performing an operation where
the cutting tool may contact hidden wiring.
Contact with a "live" wire will also make exposed
metal parts of the power tool "live" and shock the
operator.
f) When ripping always use a rip fence or straight
edge guide. This improves the accuracy of cut and
reduces the chance of blade binding.

g) Always use blades with correct size and shape
(diamond versus round) of arbour holes. Blades
that do not match the mounting hardware of the saw
will run eccentrically, causing loss of control.
h) Never use damaged or incorrect blade
washers or bolt. The blade washers and bolt were
specially designed for your saw, for optimum
performance and safety of operation.
Causes and operator prevention of kickback:
-kickback is a sudden reaction to a pinched, bound
or misaligned saw blade, causing an uncontrolled
saw to lift up and out of the workpiece toward the
operator;
-when the blade is pinched or bound tightly by the
kerf closing down, the blade stalls and the motor
reaction drives the unit rapidly back toward the
operator;
-if the blade becomes twisted or misaligned in the
cut, the teeth at the back edge of the blade can dig
into the top surface of the wood causing the blade
to climb out of the kerf and jump back toward the
operator.
Kickback is result of saw misuse and/or incorrect
operating procedures or conditions and can be
avoided by taking proper precautions as given
below.
a) Maintain a firm grip with both hands on the
saw and position your arms to resist kickback
forces. Position your body to either side of the
blade, but not in line with the blade. Kickback
could cause the saw to jump backwards, but
kickback forces can be controlled by the operator, if
proper precautions are taken.
b) When blade is binding, or when interrupting a
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
kickback 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.
Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade binding
and kickback.
