- Check the product, its battery pack and charger as well as accessories for damage before each use. Do not use the product if it is damaged or shows wear.
- Double check that accessories or cutting device are properly fixed.
- Always hold the product by its handles. Keep the handles dry and free from lubricant to ensure safe support.
- Ensure that the air vents are always unobstructed and clear. Clean them if necessary with a soft brush. Blocked air vents may lead to overheating and damage the product.
- Switch the product off immediately if you are disturbed while working by other people entering the working area. Always let the product come to complete stop before putting it down.
- Do not overwork yourself. Take regular breaks to ensure you can concentrate on the work and have full control over the product.
Trimming

- Hold the product firmly with a gap between the product and your right side.
- Stand upright, do not lean forward and pay attention to posture. Keep both feet apart to help retain your balance.
- Hold the trimming head just above the ground at an angle of approximately 30^ (Fig. 11). Avoid pressing it against the

text_image
Fig. 12ground as this can ruin the lawn and damage the product.
- Move the product with a slow regular arc from left to right before moving it back to the starting position and trimming the next area (Fig. 12).
WARNING
To avoid hazards, remove the battery pack when the user wants to transport the product in another area to prevent a random start. Failure to heed this warning could result in serious personal injury.
- Ensure the cutting device remains clean and free from off-cuts that may cause it to jam. Check regularly. Release the on/off switch and remove the battery pack before checking.

Tips
- For best results, do not cut wet grass because it tends to stick to the trimming head and guard, prevents proper discharge of grass trimmings, and could cause you to slip and fall.
- Pay special attention when performing the work close to trees and bushes. The trimming head could damage sensitive bark, and damage fence posts (Fig. 15).
- Carefully maneuver the product around objects, such as trees and bushes, ensuring it does not come into contact with them.
