Quick Answer

The 108V cordless lawnmower features an intelligent automatic variable speed system that adjusts the motor speed to match the cutting conditions. The motor will increase speed in thicker grass to provide more cutting power and reduce speed in lighter grass to help maximise battery runtime.

Tip: Changing motor speed during use is normal and does not indicate a fault.

How the Automatic Variable Speed System Works

Your 108V cordless lawnmower is designed to automatically adjust its motor speed based on the resistance it encounters while mowing.

This intelligent system helps to:

• Provide extra power when cutting long or dense grass
• Reduce energy consumption in lighter cutting conditions
• Maximise battery runtime
• Deliver consistent cutting performance

No manual adjustment is required.

Normal Motor Speed Behaviour

During operation, you may notice that:

• The motor speeds up when cutting thick, long or wet grass
• The motor slows down when cutting shorter or less dense grass
• The motor speed changes automatically as you move across your lawn
• The changes happen without any user input

This is normal operation and is part of the mower's intelligent power management system.

Why Does the Motor Speed Change?

The automatic speed control continuously monitors the workload placed on the motor.

When more cutting power is needed, the mower automatically increases motor speed.

When less power is required, it reduces motor speed to:

• Improve battery efficiency
• Extend operating time
• Reduce unnecessary power consumption

This allows the mower to deliver the right amount of power exactly when it is needed.

When Should I Be Concerned?

Motor speed changes are expected during normal use.

However, if you notice any of the following, further investigation may be required:

• The motor repeatedly stops while cutting normal grass
• The mower loses power completely
• The motor speed fluctuates excessively without cutting grass
• Warning lights or battery fault indicators are displayed

If any of these symptoms occur, please contact our customer service team via Live Chat or submit a support ticket.

Important Information

• Automatic variable motor speed is a standard feature of the 108V cordless lawnmower.
• No manual speed control is required.
• The system is designed to optimise both cutting performance and battery life.
• Motor speed will vary depending on grass length, density and cutting conditions.

Frequently Asked Questions

Why does my lawnmower speed up and slow down?

This is normal. The automatic variable speed system adjusts the motor speed according to the amount of power needed to cut the grass.

Is there something wrong with my mower if the motor speed changes?

No. Variable motor speed is a normal operating feature designed to improve performance and extend battery runtime.

Can I manually control the motor speed?

No. The motor speed is automatically controlled by the mower's intelligent power management system.

Does changing motor speed save battery life?

Yes. Reducing the motor speed when less power is needed helps maximise battery runtime without compromising cutting performance.

Why does the mower run faster in long grass?

Longer or denser grass creates more resistance, so the mower automatically increases motor speed to provide additional cutting power.

Quick Answer

If your 108V cordless lawnmower is not operating correctly, first check that the battery is fully charged and the charger is functioning correctly. The battery and charger both feature LED indicators that show the charging status, remaining battery capacity, and any faults.

Tip: Charge the battery fully before first use and recharge it as soon as the battery indicator shows a low charge.

Before You Start

Before checking the battery and charger:

• Switch the lawnmower off
• Remove the battery pack from the mower
• Inspect the battery and charger for any visible damage

Important: Only use the charger supplied with or recommended for your 108V cordless lawnmower.

3. Check the charging indicators

During normal charging:

• The red LED on the charger remains on
• The green LED on the charger flashes continuously

When charging is complete:

• The red LED remains on
• The green LED stays on continuously

This indicates the battery is fully charged and ready for use.

4. If the red LED flashes

A flashing red LED on the charger may indicate:

• A poor connection between the charger and battery
• A problem with the charger cable
• A fault with the battery pack

First, remove and reinstall the battery to ensure it is correctly seated.

If the problem continues and your machine is within warranty, please contact our customer service team via Live Chat or submit a support ticket.

Understanding the Battery Indicators

The battery LEDs provide information about the battery's condition.

If the battery becomes too hot, allow it to cool for 10–20 minutes before charging or using it again.

Lithium-Ion Battery Information

Your 108V cordless lawnmower uses a lithium-ion battery.

Unlike older battery technologies:

• Power remains consistent throughout the discharge cycle
• Performance does not gradually decrease during use
• The battery should be recharged once the red LED begins flashing

Important: Do not continue using the lawnmower when the battery indicator shows a very low charge.

If the Battery or Charger Still Isn't Working

If the battery will not charge or the charger indicators show a fault:

• Check all charger connections
• Remove and reinstall the battery
• Allow an overheated battery to cool before charging
• Contact our customer service team if the fault persists

If your machine is within its warranty period, we can advise on repair or replacement options.

Important Battery Care Tips

• Fully charge the battery before first use
• Use only the approved charger
• Do not store the battery fully discharged
• Allow hot batteries to cool before charging
• Store the battery in a cool, dry location

Frequently Asked Questions
