4. Operating Instructions

4.1 Adjusting the Tool

  • Telescopic Pole: Adjust the shaft length from 41.7 inches to 56.3 inches to suit your height and maintain an upright posture. Loosen the locking collar, extend or retract the pole, and then tighten the collar securely.
  • Auxiliary Handle: The auxiliary handle has 11 positions. Adjust it for optimal balance and comfort, reducing strain on your back and arms.
  • Pivoting Head: The cutting head can pivot to 7 different positions. This allows for precision trimming in hard-to-reach areas, under bushes, or around tree bases.

4.2 Starting and Stopping

  1. Insert a charged battery pack into the tool until it clicks.
  2. To start, press the safety lock button (usually located on the side of the handle) and then squeeze the trigger.
  3. To stop, release the trigger.

4.3 Operating Modes (Trimmer, Edger, Mower)

This 3-in-1 device easily converts between modes:

  • String Trimmer: Use for cutting grass and weeds in open areas. The 13-inch cutting diameter covers a significant area.
  • Lawn Edger: Rotate the head and use the supportive guide wheels to create crisp, clean lines along sidewalks, flower beds, and fences.
  • Mini-Mower: Attach the included mini-mower deck (if applicable) and use the guide wheels for uniform cutting of small lawn areas or areas inaccessible to larger mowers. Ensure the edger wheel is removed before placing the trimmer in the mower deck.

4.4 Auto-Feed System

The advanced dual-line auto-feed spool automatically advances the trimmer line as needed, ensuring continuous cutting without manual bumping. You can also manually advance the line by pressing the power button if required.

5. Maintenance

5.1 General Cleaning

After each use, disconnect the battery and clean the tool. Wipe down the exterior with a damp cloth. Remove any grass clippings, dirt, or debris from the cutting head, guard, and ventilation openings. Do not use harsh chemicals or abrasive cleaners.

5.2 Trimmer Line Replacement

The tool uses 2mm thick trimmer line. The package includes 4 extra refillable spools. To replace the line:

  1. Ensure the battery is removed.
  2. Refer to the specific instructions in your assembly guide for opening the spool housing.
  3. Remove the empty spool.
  4. Insert a new pre-wound spool or manually wind 2mm trimmer line onto a refillable spool according to the winding direction indicated on the spool.
  5. Reassemble the spool housing securely.

Note: If plastic blades are used, they may chip or snap if they hit hard objects. A screwdriver may be needed to change these blades.

5.3 Storage

When not in use, store the weed wacker in a dry, secure location out of reach of children. Remove the battery pack before storing for extended periods. The compact design allows for space-saving storage.
