– After striking a foreign object. Inspect

the machine for damage and make re­pairs as necessary,

– If the machine starts to vibrate abnor-

mally (check immediately).

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 connected 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 ca-

bles 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 extension
lead, otherwise it may be damaged.
Protect the cable from heat, oil and
sharp edges.

The extension lead must have a cross

section in accordance with the oper­ating instructions and be protected
against splashed water. The connec­tion must not be in water.

Electrical Safety

Warning! Switch off, remove plug

from mains before adjusting,
cleaning or if cable is cut, damaged
or entangled.

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 Centre 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:

– 1.0 mm2: max. length 40 m
– 1.5 mm2: max. length 60 m
– 2.5 mm2: max. length 100 m

Note: If an extension cable is used it
must be earthed and connected
through the plug to the earth cable of
your supply network 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 dangerous. 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 Residual Current
Device (RCD) with a tripping current of
not more than 30 mA. Always check
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 attached to the ma­chine is connected with the extension
cord. The coupling of the extension
cord must 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
authorised 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
socket elsewhere.
Products sold in AUS and NZ only:
Use a residual current device (RCD)
with a rated residual current of 30 mA
or less.
