FAQs

What is the recommended garden size for this mower?

This model is designed for medium-sized gardens ranging from 500m up to 1,000m.

Does it have a backup if the electric start fails?

Yes, it includes a traditional recoil (pull) starter as a reliable backup.

Can I use this mower to mulch grass?

Yes, the mower supports three modes: collection, side discharge, and mulching.

How often should I service the engine?

Standard practice is to check oil levels before every use and perform a full service including oil and filter changes at the start of every season.

Is the handle adjustable?

The handle is designed for ergonomic operation, but please refer to the manual for specific height adjustment capabilities.

Troubleshooting

Engine fails to start via the electric button

Check if the battery is fully charged or if the connection to the starter motor is secure.

Mower feels sluggish or loses power

Inspect the air filter for debris and ensure the underside of the cutting deck is clear of compacted grass clippings.

Poor grass collection performance

Check that the grass collector chute is not blocked and ensure the engine speed is set to maximum during operation.

Pros and Cons

Pros

  • Effortless operation thanks to the self-propelled drive system
  • Easy electric push-button ignition reduces startup fatigue
  • Flexible grass management options for different finishing preferences
  • Substantial 60L collection capacity for longer run times

Cons

  • Requires regular petrol engine maintenance such as oil changes
  • Heavy build compared to smaller electric or battery-powered models
  • Requires storage space for larger frame and collection bag
  • Not intended for very small or highly confined garden layouts

Setup, Compatibility & Care

Upon delivery, ensure the engine oil is added to the specified level before the first start. Check the fuel levels regularly and use fresh unleaded petrol. For care, keep the deck underside free of grass build-up after each use to prevent corrosion and maintain suction efficiency. Store the mower in a dry, covered area during the winter months, and consider using a fuel stabilizer if the mower will not be used for an extended period. Regularly inspect the spark plug and air filter as part of your seasonal maintenance routine to keep the 139cc engine running smoothly.
