The machine has been built according to the
highest level of technology and the recognized
safety rules. Nonetheless, residual risks re-
main when working with it.
Danger of injury to fingers and hands due to
the rotating saw blade when the work piece
is led into the machine incorrectly.
Health danger due to wood dust or saw dust.
In order to transport the circular jig-saw, lock in the
jig block. (Fig. 3)
Push the transport handle into the machine body
and turn the handle (Fig. 2) (Secured by the screw
head in the transport handle).
Before start up, follow all safety instructions.
All protective and assisting equipment must
be assembled.
Only carry out modifications, adjustment,
measurement and cleaning work on the ma-
chine when the motor is turned off. Pull out
the plug and wait until the rotating parts have
come to a stop.
The saw is constructed for cross-section
sawing for fire wood with of a maximum
length of 1 meter and a minimum diameter of
60 mm.
Regardless of the diameter of the wood, only
one piece can be put on the jack at a time.
Only do maintenance, overhaul and clea-
ning work or attend to malfunctions when
the motor is turned off (pull out the plug!).

Changing the saw blade
The saw blade can only be changed when
the machine is positioned for cutting fire
wood.
Open the side lid.
Plug in the machine to a source of electrical
current with a CEE plug. The input cable
must be secured to 16 A.
Using the main switch, turn on the machine:
the saw starts up.
Check the rotational direction! If necessa-
ry, change the polarity. (Fig. 4)
When it is switched off, the saw is decelera-
ted within 10 seconds.
The installed electrical motor is ready for operati-
on. The connection corresponds to the appropriate
VDE and DIN regulations. The connection to the
source of power by the customer as well as
any extension cables used must also corre-
spond to these regulations or the local EVU
(European Association for Accident Research
and Analysis) regulations.
Motor-braking assistance
The brakes decelerate the drive motor of the saw
within 10 seconds. If braking takes longer than 10
seconds, the machine may no longer be operated,
since the brakes are defective. The machine must
then be immediately disconnected from a source
of electrical currency. Only an electrician can deal
with this problem.
Residual risks 
Always wear personal protective clothes such
as eye protection and a dust mask.
Health danger due to noise. When working
the acceptable noise level is exceeded.
Always wear personal protection equipment
such as ear protection.
Danger due to electrical current when electri-
cal connective cables that do not conform to
Transportation
The machine can now be picked up by the trans-
port handle to lift and move it.
Start-up
Technical check before beginning operation
Put the wood in the jack.
With both hands on the handle of the jack,
swing it to the saw blade.
Then bring the jack back into the starting
position.
Do not hold the wood that is to be sawed in
place with your hands.

Maintenance

Push the adjustment rod (Fig. 5 position1)
though the lower saw blade protector to
adjust the saw blade.
Loosen the saw blade with the jaw span-
ner (Fig. 5 position 2) that comes with the
machine.
Remove the saw blade flange and change
the saw blade.
Assemble the new saw blade and tighten it
well.

Electrical connections

Operating mode/ Duty cycle
The electrical motor conceived for a duty cycle of
S6 – 40%.
S6 =
continuous operation with intermittent
load
40% =
based on 10 min. with 4 min. load, 6 min
idling
If the motor is overtaxed it automatically shuts
down since there is a thermostat coil in the motor
coils. Following a cool-down phase (varying length
of time) the motor can be restarted.
Damaged electrical cables
There is often damage to the insulation on electri-
cal cables.
Possible causes:
Pressure points, when cables are led through
window or door cracks.
Bending points, due to incorrect fastening or
cable positioning.
Damage to the insulation due to ripping the
lead out of the wall plug.
Cracks due to insulation aging.
Do not use defective electrical cables and
they are l i f e – t h r e a t e n i n g due to
defective insulation!

safety regulations are used.
In addition, in spite of all care, other, non-
obvious residual risks remain.
Residual risks can be minimized when the
"safety information," and the "appropriate
use" chapters as well as the operating in-
structions as a whole are followed.
Check electrical cables regularly for dama-
ge. Make sure that when the cables are being
checked they are not plugged into the source of
current. Electrical connections must conform to
the appropriate VDE and DIN regulations as well
as the local EVE regulations. Only use cables of
the type H 07 RN. A label with the type is required
to be on the cable.
Extension cables up to 25 meters long must
have a cross-section of 1.5 mm2, those lon-
ger than 25 meters a cross-section of 2.52.
The mains supply must be secured up to 16
ampere.
Three phase motor
The mains supply must have 380÷420 V /
50 Hz.
The mains supply and extension cables must
be five core = 3 P + N + SL.
Extension cables up to 25 meters long must
have a cross-section of 1.5 mm2.
The mains supply must be secured up to 16
ampere.
When the machine is moved or plugged in
for the first time, the rotational direction must
be checked and, if necessary, the polarity
changed.
