Electrical Safety
Switch the product off and pull the mains plug before any maintenance or cleaning. The same applies when the mains cable is damaged, cut or entangled.
Your product 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). Contact your Bosch Service Centre for details. If in doubt contact a qualified electrician or the nearest Bosch Service Centre.
For increased electrical safety 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.
Keep the supply cables away from moving hazardous parts and avoid damage to the cables; this can lead to contact with live parts.
The connections (plugs and sockets) should be kept dry and off the ground. The supply cables must be inspected for signs of damage at regular intervals and may only be used if in perfect condition.
If the supply cable on the product is damaged, it must only be replaced by a Bosch Service Centre. Only use approved extension cables.
Use only extension cords, cables, leads, cable reels that comply with EN 61242/IEC 61242 or IEC 60884-2-7. If you want to use an extension cable when operating your product, only the following cable dimensions should be used:
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.
Inadequate extension cables can be dangerous. Extension cable, plug and socket must be of watertight construction and intended for outdoor use.
For products not sold in GB:
For your safety, it is required that the plug attached to the product 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.
Products sold in GB only:
Your product is fitted with an 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.

Adjusting the handle (see figure C)
The handle (2) can be set to different positions. To change the adjustment, loosen the handle-adjustment release (1) a little and move the handle to the desired position. Retighten the handle-adjustment release (1) again.
Mounting the protection guard (see figure D)
Mounting the Wheels and Adjusting the Working Height (see Fig. E)
Press button (8) and mount the wheels (9) onto the shaft. To adjust the position of the wheels, press button (8) and slide the wheels (9) to the desired height. The wheels (9) can be moved up and down along the shaft.
Switching On and Off (see figure G)
To switch on, press and hold the On/Off switch (3).
To switch off, release the On/Off switch (3).
Lawn Trimming/Edge Cutting (see figure F)
Press button (5). Turn the bottom part of the trimmer by 180° to position the trimmer head either for lawn trimming or edge cutting. Release button (5) so that the turning mechanism engages.
Lawn trimming
Move the trimmer left and right, keeping it well away from the body. Cut higher grass in steps.
Edge cutting
Guide the trimmer along the edge of the lawn. Avoid contact with solid surfaces or walls to prevent rapid wear of the cutting line.
Cutting around trees and bushes
Carefully cut around trees and bushes so that they do not come into contact with the cutting line. Plants can die if you damage the bark.
Dismounting the spool, winding up the cutting line and mounting the spool (see figures H to J)
Press both latches of the spool cover together and remove the spool cover (11). Afterwards, remove the empty spool (12).
Cut off approx. 6.0 m line from the refill roll. Fold the line in half, so that it has a length of 2 x 3 m. Attach the line centre to the nose on the spool (13) and wind up the line - one end in each spool compartment - uniformly distributed and taut. Slide both ends of the cutting line through the holes for line guiding (14) in the trimmer head and mount the spool back into the trimmer head. Affix the spool by mounting the spool cover (11).
Line Feeding (see figure K)
Semi-automatic Line Feeding
The trimmer is equipped with a semi-automatic feeding system. The spool feeds line each time the machine comes to a stop (On/Off switch is released); too long line is cut off when the machine is started again.
Manual Line Feeding
Press the line-feed button (15), and pull the cutting line out to the desired length.
