Such defective electrical connection cables must not
be used as the insulation damage makes them ex-
tremely hazardous.
Three-phase motor 400 V/ 50 Hz
Mains voltage 400 Volt / 50 Hz.
Mains voltage and extension cables must be 5-lead
= 3 P + N + SL. - (3/N/PE).
Extension cables must have a minimum cross-sec-
tion of 1.5 mm² (≤ 25m).
Extension cables must have a minimum cross-sec-
tion of 2.5 mm² (> 25m).
The mains connection is protected with a 16 A slow-
blow fuse. The RCD breaker must have a 30 mA trip
rating.
When connecting to the mains or in the event of the
machine being moved to another location, the turn-
ing direction must be checked. It may be necessary
to change the polarity.
Turn pole inverter in the machine socket.
Motor-brake appliance
The brake slowes down the motor of the saw shaft
within 10 seconds.
The electrical braking is interrupted after maximum
14 seconds.
In case the braking takes more than 10 seconds the
machine should not be used again, as the brake is
defective. The machine implicitly needs to be discon-
nected from the power supply. Only an electronic spe-
cialist should be instructed to repair this malfunction.
Operating mode / Switch-on duration
The electrical motor is dimensioned for operating
mode S6 - 40 %.
S6 = pass operation with load exposure
40% = related to 10 min. 4min. load; 6min. pass op-
eration
If the motor is overloaded, it automatically switches
off because a thermostat protects the motor against
overloading. After a cool-down period (time varies)
the motor can be switched on again.
Check electrical connection
• Switch on the machine with the power switch, the
motor runs up.
Attention!
Check the direction of rotation!
• Three-phase AC motors must be checked for their
direction of rotation in the event of a new connec-
tion or change of location. If necessary, the direc-
tion of rotation must be changed with the phase
inverter (Fig. A)
• Upon switching off the saw shaft is slowed down
within 10 seconds.

m Alternating current motor
• The supply voltage hast to be 220-240 Volt / 50 Hz.
• Extension cables must be up to 25 m long, have a
cross cut of 1.5 mm², be over 25 m long, and have
a minimum 2.5 mm².
• The mains connection is protected with a 16 A
slow-blow fuse.
• The RCD breaker must have a 30 mA trip rating.
m Connections and repairs of the electrical equip-
ment should only be carried out by an electrical
specialist.
In case you have further questions, please specify
the following:
• Motor manufacturer
• Current type of the motor
• Information of the machine type label
• Information of the switch type label
If you send the motor back, always return the
complete power unit with electro-control. m
m Petrol engine
Engine oil
m Oil has been drained for shipping. Failure to
fill engine sump with oil before starting engine
will result in permanent damage and will void en-
gine warranty. Fill with engine oil according to
the maintenance schedule.
Topping up with fuel
m WARNING
Petrol is highly flammable:
• Only store petrol in the designated containers.
• Only fuel the unit outdoors and do not smoke when
filling.
• Petrol must be filled before starting the engine.
While the engine runs or is hot, the tank cap must
not be opened and petrol must not be filled.
• If petrol overflows, no attempts should be made
to start the engine. Instead, the machine must be
removed from the area contaminated with petrol.
Do not try to start the engine until the petrol vapours
have evaporated.
• For safety reasons, petrol tank and other tank caps
must be replaced if damaged.
