The cutting line continues to rotate for a few seconds after the trimmer is switched off.
Caution – do not touch rotating cutting line.

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). Only use approved extension cables. Contact your Bosch Service Centre for details. 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.
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 damage at regular intervals and may only be used if in perfect condition.If the supply cord is damaged, it must be replaced by a Bosch Service Centre. Extension cords should only be used if they comply with H05VV-F or H05RN-F types. If you want to use an extension cable when operating, only the following cable dimensions should be used:

– 1.5 mm2 – max length 20 m
– 2.5 mm2 – max length 50 m
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 itsplace 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.
