If The Scarifying Unit Becomes Blocked; Safety Devices; Two-Hand Operation; Operating The Machine - Viking LE 540 Manual De Instrucciones

Causes for an overload:
– Excessive rate of feed
– Blades cut too deeply into the ground
– Unsuitable or excessively long electric
cable – voltage loss ( 10.1)
– Inadequate cleaning of the cooling air
guide (inlet slots)
Recommencing operation
Resume normal operation of the machine
following a cooling period of up to 10 min
(depending on the ambient temperature).
( 10.3)
8.5 If the scarifying unit becomes
blocked
Switch off the motor immediately and
disconnect the mains plug. Then inspect
the machine, in particular the scarifying
unit, for damage and eliminate the cause
of the fault.

9. 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.
9.1 Safety devices
The scarifier is equipped with safety
devices which prevent inadvertent contact
with the blades and with ejected scarified
0478 670 9902 H - EN
material.
These include the housing, discharge flap
and correctly installed handlebar.

9.2 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. Operating the machine

10.1 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 cables which are no lighter than the
following rubber sheathed cables may be
used as electric cables:
H07 RN-F DIN/VDE 0282
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 cables must
be made of rubber or have a rubber cover
and conform to the following 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" ( 18.).
The power cable must be adequately
protected by fuse (
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).
The user must ensure that the machine is
only operated with a power supply which
meets this requirement. If necessary, this
information can be obtained from the local
electric power company.

10.2 Strain relief

4.).
During working, the strain relief
prevents any unintentional
disconnection of the electric cable and any
resulting damage to the mains connection
on the machine.
For this reason, the electric cable must be
fed through the strain relief.
● Form a loop in the power cable (1) and
guide it through the opening (2).
● Then push the loop over the hook (3)
and pull it tight.
