FAQ

Frequently Asked Questions

  • 01 What is the mulch plug and how do I use it?

    Your LawnMaster 1800W electric lawn mower came supplied with a mulching plug for when you want to leave the cut grass clippings on your lawn to act as a nutrient.

    To install the mulching plug:

    1. Lift the deflector guard and detach the grass collection bag.

    2. Lift and hold the deflector guard up with one hand.

    3. With other hand grasp the mulching plug by its upright handle and insert the plug into the rear discharge chute.

    Ensure that the locking latch snaps into place.

    4. Release the deflector guard back into position during operation.

  • 02 The mower is starting to cut unevenly, why?

    1. Check to see that the blade has been installed correctly. The blade wings should be facing up away from the ground.

    2. If the ground is uneven, raise the cutting height of the mower.

    3. Check to see if the blade is blunt: follow this guide for how to tell if its time to change your blade.

    4. The underside of the deck may be blocked with compacted grass clippings. Scrape them off if this is the case and clean around the blade.

  • 03 Why has my mower started to vibrate?

    This can happen if the steel blade has been damaged.

    1. Stop the motor, disconnect the power source, and inspect the blade. If the blade is worn replace it.

    2. If the blade is in good condition, check the tightness of the blade screw and re-tighten if necessary.

  • 04 Why is my grass trimmer not working at full power?

    The air vents may be blocked with grass trimmings. Clean the air vents to restore performance.

  • 05 Why is my trimmer making a loud noise?

    This could be one of three reasons:

    1. The line spool is dirty. Check and clean if it is.

    2. The spool is defective. Replace the spool if it is defective. Watch the video in the maintenance section above to see how.

  • 06 The trimmer has stopped cutting as well as it did. Why?

    1. Check to see if the trimmer line is worn or damaged, and replace if it is.

    2. There is insufficient line. Release more line.

    3. The trimming lines are not guided out of the spool correctly. Remove the line spool and rethread the trimming lines through the eyelets. Check the line ends are not held in the parking slots on spool.

    Replace the spool if necessary.
