OPERATION

Intended use
This grass trimmer is designed for personal use for mowing grass in gardens, e.g. around rocks, under benches, trees and in hard-to-reach places. Do not use it for commercial or other purposes.

Switching On/Off
Before switching on the trimmer, make sure that:

• It is correctly assembled;
• All locking knobs are properly secured and all bolts and nuts are fully tightened;
• The battery is inserted correctly;
• The battery is fully charged.

For safety reasons, the grass trimmer is fitted with a safety lock that prevents unintentional starting. To start the trimmer, first press the safety catch and then press the on/off switch (Fig. M). The trimmer will start .

As soon as you release the switch, the trimmer automatically shuts off and operation stops. Warning: After switching off the trimmer, always wait until the trimmer blades have come to a complete stop.
Never use the trimmer if it only starts when the switch is pressed. In this case, contact an authorized service centre. The safety switch is damaged.
Warning: Do not disable the safety switch or attempt to bypass the safety system. Do not attempt to force the switch without first depressing the safety switch.

Mowing grass
Hold the trimmer firmly with both hands at an angle of about 50° to the ground.
Stand upright and stable when handling the trimmer. Move slowly from side to side. Cut the grass from top to bottom. Keep your balance throughout the mowing operation. Always be confident when standing on slopes and walking. Never run.
Do not allow the trimmer blades to touch the ground or any obstacles. They can be damaged. Do not use the grass trimmer to dig or burrow into the ground.
Do not lean, bend or stand on one leg, etc.
Warning: Do not try to mow long or thick grass in one cut. Tall grass can wrap around the trimmer head, jam and cause the motor unit to overheat. This could damage the trimmer.
Mowing grass around trees, blocks, walls, stones, etc.
Raise and tilt the trimmer so that the trimmer blades do not touch the ground. Mow the grass at short intervals from top to bottom.
Carefully mow the grass around trees or other obstacles to avoid contact between the obstacle and the trimmer blades. We recommend keeping a safe distance of 5 cm from a tree or other obstacle. If necessary, adjust the distance of the wire guide. If the trimmer comes into contact with a tree or an-other obstacle, it can result in immediate damage. In this case, the trimming blade must be replaced immediately.

Mowing the edges of the lawn
By adjusting the vertical angle, you can use the trimmer to mow the edges of the lawn.
Adjust the horizontal and vertical angles as required – see the previous section.
Place the wire guard on the ground and slowly move the trimmer along the lawn, wall or other ob-stacle.
It is always important to adjust the vertical angle so that the trimmer head faces away from the trim-mer operator.

Overload protection
If you use the trimmer or battery in a way that draws an abnormally high current, the trimmer will au-tomatically stop without any indication. If this happens, release the switch to turn off the trimmer and stop the operation that caused it to overload. Then turn it on again.

Overheating protection
If the trimmer or battery overheats, the trimmer will automatically stop. If this happens, release the switch to turn off the trimmer and let the battery cool down. Then turn it on again.

Protection against excessive discharge
If the charge status drops excessively, the trimmer will automatically stop. If this happens, release the switch to turn off the trimmer. Remove the battery and charge it.
Note: Overload, overheating and over-discharge protection are the trimmer and battery safety sys-tems that protect them from damage. Do not attempt to bypass or modify these security features. There is a risk of serious injury or death.

MAINTENANCE AND STORAGE

Warning: Before any maintenance or cleaning of the trimmer, always make sure that it is switched off and the battery is removed.
The user must only carry out the maintenance and cleaning described in this manual. In the case of further maintenance, cleaning or adjustment, contact an authorized service centre.
Clean the trimmer after each use. This will ensure its long life.
Remove dust and dirt from the trimmer. Turn the trimmer upside down and remove any grass clip-pings from the blades, the trimmer head, the inside of the guard and the wire guard.
If the trimmer is heavily soiled, wipe it with a clean, slightly damp cloth. Wipe dry with a clean cloth. Warning: Do not immerse any part of the trimmer in water or other liquids. Do not use a hose or pressure washer for cleaning. Do not expose the trimmer to dripping or splashing water.
Remove any dirt from the ventilation holes. Use a dry cloth. Do not allow water to enter the ventilation holes. There is a risk of damage to the motor unit.
Warning: Do not use petrol, thinner, alcohol or other similar substances for cleaning. There is a risk of surface damage, deformation or cracking.

Storage

Before storing, make sure that the trimmer is switched off, clean (especially the area around the trimmer head and blades), and that the battery is removed from the motor unit.
The grass trimmer can be hung on a wall. Proceed as follows:

1. Fold the front handle down to the handle.
2. Reduce the handle length to the minimum.
3. Adjust the horizontal angle of the trimmer head so that the trimmer fits more easily against the wall.
