Before you connect the grass trimmer to the power supply, make sure that none of its moving parts are damaged and that the line spool is correctly inserted and fastened.
Never cut against hard objects when using the grass trimmer. This is imperative to avoid causing injury to the user and damage to the trimmer. Use only original replacement parts for repair and maintenance purposes. Have repairs carried out only by a qualified electrician. Examine the grass trimmer for signs of wear or damage each time before you use it and after any collisions. Have essential repairs carried out without delay.
Always keep your hands and feet away from the cutting mechanism, particularly when you switch on the trimmer. After pulling out new line, always return the trimmer to normal working position before you switch it on again. Never use replacement parts or accessories which are not foreseen or recommended by the manufacturer.

Type of protection: III
Sound power level LWA: 92 dB(A)
Sound pressure level LPA: 82 dB(A)
Replaceable NC battery: 14,4 V
Vibration measured on the
handle acc. to ISO 5349: < 2,5 m/s ^2
Power supply unit:
Mains voltage: 230 V \~ 50 Hz
Output:
Rated voltage: 18 V
Rated current: 400 mA
The noise level of this machine may exceed 85 dB(A). In this case, noise protection measures need to be introduced for the user. The machine's noise was measured in accordance with IEC 59 CO 11, IEC 704, DIN 45635 Part 21, NFS 31-031 (84/538/EEC). The level of vibrations emitted from the handle is < 2,5 m/s ^2 . Measurements were taken in accordance with ISO 5349.
5. Fitting the guard hood
●Plug the guard hood on the motor head as illustrated (Figure 3), twist counter-clockwise as far as the stop (bayonet lock) and fasten with the supplied screw (C) (Figure 4). IMPORTANT (figure 3): When you twist the guard hood, make sure that it sits squarely on the grass trimmer housing and that the stud (A) on the guard lies to the right of the stud (B) on the housing.
6. Assembling the handle and the shaft
Fit the handle to the upper shaft (Fig. 5), then join the upper and lower shafts (Fig. 6).
7. Proper use
The trimmer is designed for cutting lawns and small areas of grass in private and hobby gardens. Tools for private and hobby gardens are not suitable for use in public facilities, parks and sport centers, along roadways, on farms or in the forestry sector. For the tool to be used properly it is imperative to follow the instructions set out in the manufacturer's directions for use.
Important! It is prohibited to use the tool to chop material for composting because of the potential danger to persons and property.
8. Starting for the first time and operation
The grass trimmer is designed only for cutting grass. A short or worn nylon line will result in poor cutting performance.
IMPORTANT! Make sure that you unplug the rechargeable battery before adjusting the line length (Fig. 11)!
GB
The nylon line must be pulled out with a strong tug before starting up the grass trimmer for the first time and when the line has been worn down. Pull out the nylon line up to the edge of the guard hood (Fig. 9). Please also read section 9, „Replacing the line spool“ in this connection. The line will be cut off to the correct length when the cutting head starts up again (Fig. 9).
Remove the knife guard (D). Caution:
Risk of injury (Fig. 4)! Now insert the rechargeable battery (Fig. 11). The line will be cut to the correct length when the cutting head starts up again (Fig. 10). A short or worn nylon line produces poor cutting results.
Your grass trimmer will work at its best if you observe the following instructions:
●Never use the grass trimmer without its safety devices.
- Do not cut grass when it is wet. The best results are had on dry grass.
●To switch on your grass trimmer, press the safety lock-off button (Fig. 1/Pos. 2).
●To switch off your grass trimmer, let go of the ON/OFF switch (Fig. 1/Pos. 2).
- Do not move the grass trimmer against the grass until the switch is pressed, i.e. wait until the trimmer is running.
- For the correct cutting action, swing the grass trimmer to the side as you walk forward, holding it at an angle of approx. 30^ as you do so (see Figure 12 and Figure 13).
●Make several passes to cut long grass shorter step by step from the top (see Figure 14).
●Make full use of the guide hood in order to avoid unnecessary line wear.
- Keep the grass trimmer away from hard objects in order to avoid unnecessary line wear.
9. Replacing the line spool
IMPORTANT! Make sure that you unplug the rechargeable battery before replacing the line spool (Fig. 11)!
●Attach the knife guard (D) (Fig. 4).
●Hold the spool receptacle in place and press the line spool downwards. Turn the pressed down line spool counterclockwise until it can be removed (Fig. 7).
- Replace the empty line spool with a full one; feed the end of the line through the lateral hole of the spool if necessary.
●Place the line spool on the spool receptacle, hold
the spool receptacle in place, then press the line spool downwards while turning it clockwise until the spool is snug.
As you do this, feed the line through one of the slots of the spool receptacle up to the edge of the guard hood (Fig. 8 and Fig. 9).
- Remove the knife guard (D). Caution: Risk of injury (Fig. 4)
●The line will be cut to the correct length when the cutting head starts up again (Fig. 10).
Caution! Catapulted pieces of nylon line may cause injury!
10. Charging the rechargeable battery
●You can remove the rechargeable battery by firmly pressing both locking tabs (A) while pulling out the battery (Fig. 11).
- Check to see if the voltage specified on the rating plate of the charging unit matches the mains voltage. Connect the power supply unit (A) to the charging adapter (B). Plug the power supply unit into the socket outlet. The green LED on the charging adapter lights up (Fig. 15).
●Plug the rechargeable battery (C) into the charging adapter. The red LED on the charging adapter lights up and shows the charging process (Fig. 15). The time it takes to fully recharge an empty battery is approximately 4 hours, while a partially charged battery takes correspondingly less time. The rechargeable battery can become a little warm during the charging process, which is normal.
11. Cleaning and maintenance
- Switch off and unplug the grass trimmer before putting it away or cleaning it.
- Remove deposits from the guard hood with a brush.
●Clean the plastic body and plastic parts with a mild household detergent and a damp cloth.
●Never use aggressive agents or solvents for cleaning purposes!
●Never spray down the grass trimmer with water.
●Prevent water getting into the trimmer at all cost.
●In order to make it easier for you to store the unit, the assembled shaft can be taken apart. To do this, firmly press both locking tabs (A) while pulling the two shaft pieces apart from each other (Fig. 16).
IMPORTANT: Remove the rechargeable battery first (Fig. 11).
