• if the machine starts to vibrate abnormally (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 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 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 mm max. length 40 m
• 1 . 5 ^2 max. length 60 m
• 2 . 5 ^2 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.

Maintenance

▶ Always wear gardening gloves when handling or working near the sharp blades.
- Keep all nuts, bolts and screws tight to be sure that the machine is in safe working condition.
