Petrol Powered Rotary Lawn Mowers Follow

 We want you to get the most out of your petrol rotary lawn mower, and enjoy using it from the beginning. 

Subsequently, we decided to create a basic guide, full of tips and advice, including answers to the types of questions new petrol rotary lawn mower owners frequently ask,  to save you time and give you confidence. 

That way you can get the best from your new purchase and use it efficiently and easily every time. 

Assembly: Your new petrol rotary mower will arrive ‘boxed' and there is a minimal element of assembly. This is usually limited to attaching the 'Handlebars' and 'Grass catcher' .

Fuel: Your new lawn mower has a 4 Stroke engine, so Oil and Petrol are put in separate compartments, no mixing required.

We understand manuals can be difficult to read from time to time and translations are not always as helpful as they might be. However, do try to read manual/instructions as thoroughly as you can and keep them to hand, at least during early use. 


  • Modern fuel contains ethanol, which absorbs moisture and causes the fuel to deteriorate in as little as 30 days, causing damage and starting issues if left in the tank. Our suggested solution is either drain the tank if are going to leave it for a while or always add fuel stabilising additive to all fuel before filling up your tank.
  • For the same reasons you should only put 'Fresh Unleaded Petrol' in your tank. Old fuel will degrade quickly if it has not already done so.


  • It is important not to under-fill or over-fill your machine. Please refer to your manufacturers guidelines as to the quantity.
  • Regular oil changes protect your engine from damage and excessive wear. Do refer to your ‘Engine’ manual regarding schedules for regular oil changes.
  • Not all models come with oil in the box and none with oil in the tank. It is advisable to check and have some ready just in case. The type should be 10/30 Lawnmower Grade Oil, otherwise known as SAE 30.
  • Oil needs to be changed after the first 5 hours of use. Running in of the machine can cause minute particles of metal debris in the engine, which an oil change and flush removes safely.

 Starting : If you are have difficulty starting your machine, it is always advisable to check the following: 

  • Ensure you are holding in the 'OPC Bar' (Operator Presence Control). If you are not holding this in you will be unable to pull out the recoil.
  • If you have a 'Fuel Switch', please ensure this is on.
  • If there is a 'Primer', check you have primed the machine.
  • If there is a 'Throttle', check that this is fully on to start the machine and then reduce the throttle once the machine has started.

Throttle: Again, if there is a throttle on your model, do remember that it does not affect the speed of the machine, it simply reduces or increases the 'Revs' of the engine.

Storage: Petrol Lawnmower engines are not waterproof. So make sure you store yours in a dry place, covered if possible.

Grass and Mud:

  • Wet and rotting grass causes metal components to rust and grass and dirt in or around the engine can cause overheating and damage. Always make sure you clean the cutting deck regularly and thoroughly.
  • If your mower does not have a 'Deck Wash Port' (an attachment for a hose) you will need to tip the machine to clear the deck from beneath. Always tip from front to back so that the machine pivots/rests on the back wheels.

NB: Never tip from side to side as this causes the oil to flood the air filter.   This can contaminate your spark plug and carburettor.

Servicing: Don’t forget that Annual Servicing is recommended by the manufacturers and is a requirement if you want to extend the guarantee beyond the first year. Out of tune engines and blunt blades can result in poor cutting, poor collection, and environmental pollution.

And finally, we’d like to thank you for your custom. We hope that these guidelines will be of assistance and that you enjoy using your new mower. If you do have any concerns not covered by this letter, please contact us on customercare@mowdirect.co.uk
