• Never work on a slippery hillside or slope.
• Never use the device in the vicinity of highly flammable liquids or gases – Risk of fire and/or explosion!
• After contact with a foreign object:
  • Switch off the engine.
  • Examine the device for damage

Lengthening the cutting string

1. Let the engine run at full throttle and tap the string head on the ground.
   The cutting string will be extended automatically.
   The blade on the safety shield shortens the cutting string to the permissible length.

Cleaning the guard

1. Switch off the device.
2. Carefully remove mowing debris with a screwdriver or similar tool.

Clean the guard regularly to prevent the shaft tube from overheating.

Trimming

1. Examine the terrain and determine the desired cutting height.
2. Guide and hold the string head at the desired height.
3. Swing the device from side to side in a sweeping, scythe-like motion.
4. Always keep the string head parallel with the ground.

Close trimming

1. Hold the device so that it is tilted forward at a slight angle and moves just above the ground.
2. Always trim away from your body.

Trimming along fences and foundations

Caution!
Do not come into contact with solid structures – Danger of recoil!

1. Move the unit slowly and carefully without allowing the cutting string to hit any obstacles.

Trimming around tree trunks

1. Guide the device slowly and carefully around tree trunks, ensuring that the cutting string does not touch the tree bark.
2. Mow from left to right around tree trunks.
3. Cut grass and weeds with the tip of the string and keep the string head tilted slightly forwards.

Trimming along stone walls, foundations and tree leads to increased string wear.

Mowing

1. Tilt the string head to the right at an angle of 30 degrees.
2. Move the handgrip to the desired position.

Caution!
Remove foreign objects from the working area. Risk of injury / damage to property from ejected foreign objects.

Mowing with the cutting blade

When mowing with the cutting blade, the cutting blade should be guided in a curving horizontal motion from one side to the other.

Caution!
Before using the cutting blade, observe the following additional instructions:

• Use the shoulder strap.
• Check the safety hood and cutting blade for correct installation.
• Wear protective clothing and eye protection.

Do not use weed cutter blades for cutting brushwood and young trees!

Caution!
Only use original cutting knives and accessories!
Non-original parts can cause injuries and device malfunctions!

Avoiding recoil

Caution!
Danger of recoil / risk of injury!

Do not use the cutting blade in the vicinity of fixed obstacles –
Never use blunt cutters and avoid uncontrolled contact with foreign bodies. Otherwise there will be an increased risk of the equipment kickback, which could throw the machine around. As a result the operator could be make involuntary movements, which could lead to serious injuries.

Jamming
Dense vegetation, young trees or brushwood can jam the cutting blade and stop it turning.

• Avoid jamming by noting the direction in which the vegetation leans and then cutting from the opposite side.
• If the cutting blade becomes entangled during cutting:
  • Switch off the engine immediately.
  • Hold up the device so that the cutting blade does not jump or break.
  • Push the caught material away
