    Why my Spear & Jackson Lawn Mower won't start?
    • W
      William AvilaAug 17, 2025
      Your Spear & Jackson Lawn Mower might fail to start due to several reasons. It could be a clogging issue, so check underneath the mower and clear any obstructions, while wearing gardening gloves. Alternatively, the battery may not be fully charged or properly inserted, so ensure the battery is charged and correctly placed. If the grass is too long, increase the cutting height and tilt the mower to reduce the starting load. The battery could also be too hot or cold, in which case, allow it to cool or warm. Ensure the isolator key is correctly inserted. Also, note that a short delay in the motor starting is normal; hold the On/Off switch for 1–3 seconds to start the motor.

    • D
      Daniel NewtonSep 8, 2025
      If no charging procedure is possible for your Spear & Jackson Lawn Mower, it could be due to contaminated battery contacts. Clean the battery contacts, for example, by inserting and removing the battery several times, or replace the battery. Another reason might be a defective battery due to a disconnection in the battery's individual cells; in this case, replace the battery.

    Why aren't the charging LEDs lighting up on my Spear & Jackson Lawn Mower?
    • J
      Joseph HudsonSep 12, 2025
      If the charge control LEDs do not light up after inserting the mains plug into the socket for your Spear & Jackson Lawn Mower, it could be because the mains plug of the battery charger is not plugged in properly. Ensure the mains plug is fully inserted into the socket outlet. Alternatively, the socket outlet, mains cable, or battery charger could be defective. Check the mains voltage and, if necessary, have the battery charger checked by an authorized customer service station.

    How to improve battery life on Spear & Jackson Lawn Mower?
    • J
      Justin GonzalesSep 12, 2025
      If the area cut by your Spear & Jackson Lawn Mower isn't large enough due to battery duration, several factors could be at play. If the height of cut is too low, increase it and walk slower. If the grass is too high, increase the height of cut and walk slower. Also, if the grass is wet or damp, wait until it's dry and walk slower. Finally, if the grass is dense, increase the height of cut, walk slower, and cut more frequently.
