Before Use Checklist
Ensure that you carry out all procedures below before starting the engine or operating the equipment. All procedures
described are generic in nature and slight variations between different models may exist. Failure to follow the checklist
and carry out the procedures correctly may result in making the product warranty void. The product is NOT supplied with
engine oil, although traces of oil from the manufacturing process may be present. It is essential to add adequate engine
oil of the correct type to the engine before use – see Checking and Changing Engine Oil. Failure to add engine oil will void the product warranty.
Engine Oil
Air Filter
Four-stroke engines require engine oil in the crankcase for lubrication of internal components. Severe or irreparable damage may occur if the
engine is allowed to run without engine oil. The engine oil level requires regular maintenance. Check the engine oil level and ensure that the oil
level is at or just under the maximum level indicator.
Some machines may feature an oil level sensor that will prevent the engine being started or automatically stop the engine if the oil level falls
below an acceptable level. This system, however, is not to be solely relied upon. Always check that the engine oil level is at or near the “MAX”
indicator before starting the engine. See Checking and Changing Engine Oil.
The air filter is used to prevent dirt and other particles from possibly entering the engine and causing internal damage to it. The air filter requires
regular maintenance.
Always check the air filter before starting the engine. See Checking, Cleaning and Replacing the Air Filter.
Adequately fill the fuel tank with the correct fuel type.
•
Use non-ethanol unleaded (higher RON values will provide best engine performance). Do not use old or contaminated fuel.
•
To fill or top up fuel:
•
Place the machine in an upright position on a flat and level surface.
•
Clean the machine around the fuel filler so that no dirt or other material enters the engine when the cap is removed.
•
Remove (rotate left) the fuel filler cap.
•
Using a funnel, carefully fill the tank with fuel. Do not fill above the top of the strainer (if equipped) or otherwise overfill the tank.
•
When finished, reinstall (rotate right) the fuel filler cap until firm. Wipe away any residual fuel from the machine. If fuel has been spilt,
move the pump away from the spillage before starting the engine.
Petrol/fuel/gasoline is extremely flammable – keep clear of naked flames or other ignition sources. The engine must be
cool before refuelling.
