Usage Features
The trimmer offers several adjustable features for user comfort and specific trimming needs:
- On/Off switch (1): Located on the main handle for easy operation.
- Power cable strain relief (2): Helps prevent damage to the power cable.
- Spool storage (3): For convenient storage of the cutting line spool.
- Height adjustment locking collar (4): Allows adjustment of the telescopic tube (5) to suit the user's height. To adjust, turn the collar clockwise to unlock, slide the tube up or down, then turn anticlockwise to lock.
- Pivot button (6): Enables the trimmer head to pivot to seven different positions for various trimming and edging angles. The first three notches are for trimming, and notches four through seven are for edging.
- Edging wheel (7): Can be slid into a slot on the motor housing (11) for stable edging.
- Cutting head (8): The main component for cutting grass.
- Flower guard (9): A protective guard that can be folded down for trimming or folded up against the housing (park position) when not needed, preventing damage to plants not intended for cutting.
- Safety guard (10): Must be properly fitted before use to ensure safety. It slides over the cutting head and is secured with three screws.
- Auxiliary handle (11, 12): Adjustable to different positions for comfortable handling. It is secured by a wing nut (15).
- Rotational lock button (13): Used to rotate the main handle (14) by 90° for edging.
Starting and Stopping:
To switch on, depress the on/off switch. Release the switch to turn off. The cutting head will continue to rotate for a few seconds after switching off, so hands and feet should be kept clear. The on/off switch must not be locked in place.
Cutting:
- Always switch on the trimmer before approaching the grass.
- Avoid cutting damp or wet grass.
- Do not overload the trimmer.
- Keep the power cable trailed behind you to prevent damage.
- Cut grass by swaying the trimmer sideways, tipping it forwards by about 30° for long grass, cutting in layers from top to bottom.
- Use the flower guard to maintain distance from obstacles and desired plants.
- Only use the correct cutting line; never use metal or fishing line.
Lengthening the Cutting Lines:
The trimmer has a fully automatic dual line system. If lines are not visible, the spool needs to be renewed. Manual line length adjustment is possible by pressing the line-release button and pulling the cord ends.
Maintenance Features
- Cleaning: Always disconnect the plug from the mains socket before cleaning. Do not spray water directly onto the trimmer. Clean the trimmer, cutting device, and protective cover after each use to remove grass and soil. Ensure ventilation slots are clear. Use a soft brush or cloth for cleaning. Avoid cleaning agents and solvents that could damage the plastic housing.
- Replacing the Trimming Assembly:
- Disconnect the plug from the mains socket.
- Turn the trimmer over so the cutting head faces upwards.
- Press the two retaining tabs on the side of the cutting head and remove the spool cap (16).
- Remove the old line spool (17).
- Insert a new spool with the smooth side facing upwards, threading the two lines (18) through the line eyelets. Ensure lines do not slip out of spool slots.
- Replace the spool cap (16), ensuring retaining tabs are inserted into recesses.
- Press the line-release button, pull the cord ends slightly beyond the cord cutter, and release.
- Alternatively, wind 1.6mm nylon string (max 2 x 5m) onto the spool, ensuring it's parallel and against motor rotation direction.
