Keep supply cables and extension cables away from
the blade. The blade can cause damage to the cables and
lead to contact with live parts. Beware electric shock haz-
ard.
Do not modify this product. Unauthorized modifications
may impair the safety of your product and may result in in-
creased noise and vibration.
Avoid mowing in bad weather conditions especially when
there is a risk of lightning.
Remove the plug from the socket:
– whenever you leave the machine,
– before clearing a blockage,
– before checking, cleaning or working on the machine,
– after striking a foreign object. Inspect the machine for
damage and make repairs as necessary,
– if the machine starts to vibrate abnormally (check immedi-
ately).
Power supply
The voltage indicated on the rating plate must correspond
to the voltage of the power source.
We recommend that this equipment is only connect ed into
a socket which is protected by a circuit-breaker that would
be actuated by a 30 mA residual current.
Only use or replace power supply cables for this unit which
correspond to the types indicated by the manufacturer.
Never touch the mains plug with wet hands.
Do not run over, crush or pull the power supply cable or ex-
tension lead, otherwise it may be damaged. Protect the ca-
ble from heat, oil and sharp edges.
The extension lead must have a cross section in accord-
ance with the operating instructions and be protected
against splashed water. The connection must not be in wa-
ter.
Electrical Safety
Warning! Switch off, remove plug from mains before
adjusting, cleaning or if cable is cut, damaged or entan-
gled.
The blades continue to rotate for a few seconds after
the machine is switched off.
Caution – do not touch the rotating blade.
Your machine is double insulated for safety and requires no
earth connection. The operating voltage is 230 V AC, 50 Hz
(for non-EU countries 220 V, 240 V as applicable). Only use
approved extension cables. Contact your Bosch Service Cen-
tre for details.
Extension cords/leads should only be used if they comply
with H05VV-F, H05RN-F types or IEC type design (60227
IEC 53, 60245 IEC 57).
If you want to use an extension cable when operating your
product, only the following cable dimensions should be used:
–1.0mm
2
: max. length 40 m
–1.5 mm
2
: max. length 60 m
–2.5 mm
2
: max. length 100 m
Note: If an extension cable is used it must be earthed and con-
nected through the plug to the earth cable of your supply net-
work in accordance with prescribed safety regulations.
If in doubt contact a qualified electrician or the nearest Bosch
Service Centre.
WARNING! Inadequate extension cables can be dan-
gerous. Extension cable, plug and socket must be of
watertight construction and intended for outdoor use.
It is recommended for increased electrical safety to use a Re-
sidual Current Device (RCD) with a tripping current of not
more than 30 mA. Always ch eck your RCD every time you use
it.
If the supply cord is damaged, please contact your nearest
Bosch Service Centre.
For products not sold in GB:
WARNING: For your safety, it is required that the plug at-
tached to the machine is connected with the extension cord.
The coupling of the extension cord m ust be protected against
splash water, be made of rubber or coated with rubber. The
extension cord must be used with a cable strain relief.
The connection lead must be inspected for signs of visible
damage and ageing at regular intervals and may only be used
if in perfect condition.
Products sold in GB only: Your product is fitted with a
BS 1363/A approved electric plug with internal fuse (ASTA
approved to BS 1362).
If the plug is not suitable for your socket outlets, it should be
cut off and an appropriate plug fitted in its place by an author-
ised customer service agent. The replacement plug should
have the same fuse rating as the original plug.
The severed plug must be disposed of to avoid a possible
shock hazard and should never be inserted into a mains sock-
et elsewhere.
