as similar to be machined hard
plastics only.
Machining of other materials is not
permitted and may be carried out in
specific cases only after consulting
with the manufacturer.
No metal workpieces may be
machined.
Do not cut round stock without
suitable jigs or fixtures. The rotating
saw blade could turn the work-piece.

instruction manual before attempting
assembly or operation.
Keep this operating instruction close
by the machine, protected from dirt
and humidity, and pass it over to the

new owner if you part with the tool.
No changes to the machine may be
made.
Daily inspect the function and
existence of the safety appliances
before you start the machine.
Do not attempt operation in this case,
protect the machine by unplugging
the mains cord.

this machine.
For the safe handling of sawblades
wear work gloves.
Observe the chapter “save operation”
in this manual.
Check the correct rotation of the
sawblade before operating the
machine.
Do not start cutting operation until
sawblade is at full speed.
Control the stopping time of the
machine, it may not be longer than
10 seconds.
Do not use side pressure to stop
rotating blade.
Insure that the work piece does not
roll when cutting round pieces.
Use suitable table extensions and
supporting aids for difficult to handle
workpieces.
Always hold and guide the
workpieces safely during machining.
Pay particular attention to instructions
on reducing the risk of kickback.
The supplied raving knifemust
always be used. Adjust the space to
the sawblade to be max 5mm.
Do not perform any operation for
which the tool has not been designed
for, e.g. do not use this table saw to
cut logs or firewood.
Do not perform any operation
freehand.
Never reach around or over the saw
blade.
When ripping narrow workpieces
(smaller than 120mm) use as push-
stick or push-wood.
Push stick or push wood must stay
with the machine when tool is stored
and not in use.
Always use the mitre gauge for
cutting off.
The use of dado-blades and groove
cutters is not permissible.

workpieces will not be caught and
thrown away by the rising saw blade
teeth.
Remove cut and jammed workpieces
only when motor is turned off and the
machine is at a complete standstill.
Install the machine so that there is
sufficient space for safe operation
andwork piece handling.
Keep the inside of the cabinet clear
of sawdust and wood chips. Make
sure the motor fan and fan cover are
kept clear of sawdust.

carcinogenic substance.
Always use a suitable dust extraction
device
Before machining, remove any nails
and other foreign bodies from the
work piece.
Specifications regarding the
maximum or minimum size of the
work piece must be observed.
Cut thin or thin-walled work-piece
only with fine-toothed saw blades.
Never cut several work-pieces at the
same time –and also no bundles
containing several individual pieces.
Risk of personal injury if individual
pieces are caught by the saw blade
uncontrolled.
When cutting round stock, use a
suitable jig to prevent the work-piece
from turning.
Never cut work-pieces containing the
following materials:
-Ropes, strings, cords, cables and
wires.
