If The Mowing Blade Blocks; Thermal Motor Overload Protection; Safety Devices; Two-Hand Operation - Viking ME 443 Manual De Instrucciones

9.3 If the mowing blade blocks

Switch off the motor immediately and
disconnect the mains plug. Then eliminate
the cause of the fault.

9.4 Thermal motor overload protection

If an overload of the motor occurs during
operation, the built-in thermal overload
protection device automatically switches
off the motor.
Causes for an overload:
– mowing excessively high grass or
cutting height adjusted too low,
– excessive rate of feed,
– inadequate cleaning of the cooling air
guide (inlet slots),
– mowing blade is blunt or worn,
– unsuitable or excessively long electric
cable – voltage loss ( 11.1).
Recommencing operation
Resume normal operation of the machine
following a cooling period of up to 10 min
(depending on the ambient temperature)
( 11.).

10. Safety devices

The machine is equipped with several
safety devices for safe operation and for
the prevention of improper use.
Risk of injury
If a safety device is found to be
defective, the machine must not be
operated. Consult a specialist
dealer; VIKING recommends
VIKING specialist dealers.
10.1 Safety devices
The lawn mower is equipped with safety
devices, which prevent inadvertent contact
with the mowing blade and with ejected
clippings.
These include the housing, discharge flap,
grass catcher box and correctly-installed
handlebar.

10.2 Two-hand operation

The motor can only be switched on by
pressing and holding the ON button with
the right hand and then pulling the
motorstop lever to the handlebar with the
left hand.

10.3 Motor run-down brake

When the motorstop lever is released, the
mowing blade comes to a complete
standstill in less than three seconds.
An integrated motor run-down brake
shortens the run-down time until the blade
stops.

11. Operating the machine

11.1 Electrical connection

Danger of electric shock!
Observe the safety instructions in
the section "For your safety" (
If using a cable drum, the
connection cord must be unwound
completely, otherwise electrical
resistance may cause loss of power
and overheating.
Only electric cables which are no lighter
than rubber sheathed cables H07 RN-
F DIN/VDE 0282 may be used as electric
cables.
Recommended minimum cross-
section:
up to 25 m Length: 3 x 1.5 mm²
up to 50 m Length: 3 x 2.5 mm²
The connectors of the electric cable must
be made of rubber or have a rubber cover
and conform to the standard
DIN/VDE 0620.
The mains voltage and mains frequency
must correspond to the information on the
identification plate and the information
contained in the section
"Technical specifications" (
The power cable must be adequately
protected by fuse ( 19.).
This machine is intended for operation with
a power supply having a system
impedance of Z at the transfer point
max
(house connection) of maximum
0.49 ohms (at 50 Hz).
