Troubleshooting

Check that the battery is charged

We know it sounds silly, but it’s always worth double checking that your battery is actually charged! Press the button on the top of the battery to show the state of charge display – if 1 green light is shown, you will need to charge your battery.

Place the battery in its charging cradle. The battery takes just 1 hour to charge, with each of the 4 state of charge indicator LEDs lighting up green in turn as it charges. When all 4 lights are illuminated, your battery is fully charged.

Check that the battery has clicked into place

Place the battery in its charging cradle and push it down until you hear it click into place.

Make sure the lawnmower is properly assembled

Your lawnmower comes with a full manual, detailing how to assemble it correctly. Refer to your manual or download another version here.

Are you pressing the safety button?

Press and hold the safety button for 5 seconds first, then lift the green handle lever up to the handle. The green safety button is located on the side of the lawnmower’s handle. The safety button can be released while you mow, but the green handle lever must be continuously lifted and pulled towards the handle.

Lift the green handle lever constantly to keep the lawnmower working

The green handle lever must be continuously lifted and pulled towards the handle. The machine will stop when the green handle lever is released.

The battery terminals may be dirty or damaged

Remove the battery before carrying out any maintenance work.

If dirt or dust gets into contact with the battery terminals, they won’t connect properly. Remove the battery and use a dry, soft cloth to clean the terminals on the battery and battery housing. The terminals are located on the base of the battery, at the back and bottom of the battery cradle.

Re-insert the battery and try using the lawnmower again.

The blade may be jammed

Remove the battery before carrying out any maintenance work.

If the blade is jammed, the machine will cut out. Remove the grass bin and lay the lawnmower on its side. Use a blunt implement to remove any obstructions from around the blade and clean the base of the lawnmower.

The safety key is in the ‘Off’ position or is not inserted

Make sure the safety key is turned to the ‘On’ position - the mower will not start if the key is not in place or is turned to the ‘Off’ position.

If there are no signs of damage, re-insert the battery and try using the lawnmower again.

The type of grass/ foliage you’re cutting will affect runtime

Runtime will be reduced depending upon the thickness/ length of grass being cut. Check that the height adjuster has been correctly selected for the grass type and length. If you are cutting something thick, try doing it in stages rather than all at once if you’re struggling. It’s not recommended to mow wet grass.

Check if the blade is worn or damaged

Blades naturally wear down over time – get in touch with us if you think yours needs replacing.

Make sure the blade is fitted correctly. Your lawnmower comes with a full manual, detailing how to assemble it correctly. Refer to your manual or download another version here.

Check the battery lights

1 green light

Charge the battery for 1 hour until all 4 lights turn solid green.

4 solid red lights

This suggests that the battery has been stored in extremely hot/ cold temperatures. Keep the battery somewhere room temperature for 24 hours and then fully charge the battery for 1 hour.

If there are still 4 solid red lights, get in touch with us as we may need to send you a replacement part.

0 lights while on the charging stand

Check that the battery is correctly fitted to the terminals in the charging cradle.

There should be a red light showing on the charger when it’s plugged in to the mains to indicate that there is power going to it. Ensure the plug socket is supplying power, and use another charging point if not.

Press the green button on the battery – if 4 solid green lights illuminate, the battery is fully charged.

Check the charger

If you’ve worked your way through the above steps and your lawnmower is still not working, it may be an issue with your charger. There are a few ways you can check if there’s an issue with the charger.

If the battery is fitting loosely in the charging cradle, there will be excessive movement when the battery is plugged in and it may not charge correctly. Get in touch with us as we may need to send you a replacement part.

Check to see if the charger gets warm when it is charging the battery. Check for signs of damage to the charger cable. If it’s ripped or frayed, or if the terminals pins are broken on the charger, you need a replacement charger to ensure your lawnmower works safely. Get in touch with us if you need a replacement charger.

Check for signs of damage to the battery terminals. If you can’t see anything wrong with your charger but it’s still not working, try plugging it into another socket as it may be an issue with the mains.

If you have a spare charger, try using that one instead.

If you’ve taken all the steps to check your battery and charger and your lawnmower still isn’t charging, get in touch with us as we may need to send you a replacement part.

Make sure you’re fitting the grass bin correctly

When constructing the grass bin, ensure the 3 plastic clips have been securely latched around the metal pole.

To fit the bin to your mower, lift the protective flap on the back of the lawnmower and hook the grass bin onto the tabs located on the back of the mower. The protective flap will then lie on the top of the grass bin.

Make sure you’re emptying the grass bin correctly

When the grass bin indicator lowers, the grass bin needs emptying.

Lift the protective flap on the back of the grass bin. Using the grass bin handle, lift and pull the grass bin away from the lawnmower before emptying it.

Make sure you empty the bin and clear the chute after each use to prevent a build up of grass. A build up will lead to poor collection of grass.

Avoid blockages in the grass bin

Remove the battery before carrying out any maintenance work.

Blockages in the grass bin can occur if it is too full, and it may block the chute, too. Empty the bin and clear the chute and blade from any build up of grass or foliage.

The blade may be jammed

Remove the battery before carrying out any maintenance work.

If the blade is jammed, the machine will cut out. Remove the grass bin and lay the lawnmower on its side. Use a blunt implement to remove any obstructions from around the blade and the base of the lawnmower.

Check the cutting height adjuster

Check that the cutting height is at the correct level for the grass you are cutting. If it is set too low, the lawnmower will struggle to cut the grass and will stop working.

Safety key damaged

Check the key for signs of damage or stress marks. If the key is damaged, you can order a replacement key by getting in touch with us.

Lost the safety key?

The safety key can be turned to the ‘Off’ position and stored on the mower to prevent you from losing it. If the key has been misplaced, you can order a replacement key by getting in touch with us.

The lawnmower isn’t cutting correctly

Use the height adjuster to select the correct height for the type of grass you’re cutting. Incorrect settings will reduce the lawnmower’s runtime.

Trouble moving the height adjuster

The height adjuster lever should move easily, sliding into any of the 6 settings.

If the lever does not move into the notches for the required cutting height, get in touch with us as we may need to send you a replacement part.
