5. Operating Instructions
Before operating, ensure all safety precautions are followed and the trimmer is properly assembled.
- Power On: Press the power button on the control panel to turn on the trimmer.
- Select Speed: Use the speed selection button to choose between three settings: Low (3,500 RPM), Medium (5,300 RPM), or High (6,500 RPM). The Automatic Torque Drive Technology can also be engaged for automatic speed adjustment based on load.
- Start Trimming: Squeeze the trigger to start the cutting line rotation. Maintain a steady, sweeping motion to cut grass and weeds.
- Feeding Line: To advance the cutting line, gently tap the trimmer head on the ground while the motor is running. This is the "bump & feed" mechanism.
- Reverse Function: If the trimmer line becomes tangled with dense grass or weeds, press the reverse button on the control panel. This will temporarily reverse the rotation of the trimmer head to help untangle the line without manual intervention.
- Power Off: Release the trigger to stop the cutting line. Press the power button again to completely turn off the trimmer.

6. Maintenance
Regular maintenance ensures optimal performance and extends the life of your trimmer.
- Cleaning: After each use, remove any grass, dirt, or debris from the trimmer head, shield, and motor housing. Use a dry cloth or soft brush. Do not use water or harsh chemicals.
- Trimmer Line Replacement: When the cutting line runs out, replace it with new line. The XRU15Z uses industry standard spindles (M10x1.25 LH). To load new line, align the arrows on the bump head, feed the line through, and twist the head to wind it.
- Battery Care: Store batteries in a cool, dry place away from direct sunlight. Do not store fully discharged batteries for extended periods. Charge batteries fully before storage and periodically during long storage periods.
- Inspection: Periodically check all screws, nuts, and bolts for tightness. Inspect the cutting line and trimmer head for wear or damage. Replace worn or damaged parts immediately.
