How do I do a safety key check on my Cordless Lawnmowers

Quick Answer

If your cordless lawnmower is not starting, it may be due to an issue with the safety key not correctly activating the internal microswitch. You can test this by checking whether the microswitch is being properly engaged when the safety key is inserted.

Important: Always ensure the mower is switched off and the battery is removed before carrying out any checks.

Before You Start

Before performing any safety key checks:

• Switch the lawnmower off
• Remove the battery
• Remove the safety key
• Ensure the mower is on a stable surface

Important: Do not attempt this check while the mower is powered.

How to Perform a Safety Key Check

Step 1: Remove the safety key

• Take out the safety key tab from the mower
• Set it aside safely

Step 2: Prepare the controls

• Hold the start/stop button on the handle
• Pull and hold the operating lever

Important: This simulates normal starting conditions.

Step 3: Test the microswitch

• Locate the small black microswitch inside the safety key slot
• Using a long insulated tool (e.g. flat-head screwdriver), gently press the microswitch down

If the mower starts when the microswitch is pressed, this indicates the safety key is not correctly engaging it.

What This Means

If the mower starts when manually pressing the microswitch:

• The safety key is likely misaligned or not functioning correctly
• It is not making proper contact with the switch

If the Issue Persists

If your safety key is not working correctly:

• Contact our Technical Support Team
• Request a replacement safety key
• Provide your model number for compatibility

Important: Do not operate the mower without a properly functioning safety key fitted.

Temporary Advice

In some cases, the safety key may not be correctly shaped or aligned. If advised by support:

• It may be adjusted slightly to ensure proper contact with the microswitch

Important: This should only be done if instructed by Technical Support.

Important Information

• The safety key is a critical safety component
• The mower will not operate without correct engagement
• Never bypass safety systems permanently
• Always ensure the microswitch is fully activated by the key
