MAINTENANCE
Regular maintenance is essential to keep your EVO-SYSTEM
Engine and its accessories in serviceable condition. We
recommend that only competent operators who have experience
in servicing and maintaining petrol engines attempt these
procedures. If in doubt have the machine serviced at an Evolution
approved Service Centre.
1. Engine oil replacement
Note: Engine oil is easier to replace when the engine has been
run up to temperature and the oil is warm.
• Ensure that the engine is positioned on a hard level surface.
• Remove the oil filler cap. (Fig. 18)
• Place a suitable oil collection pan under the engine.
• Remove the oil drain plug so that the oil can drain completely
from the engine. (Fig. 19)
WARNING: Be careful. Contact with used engine oil can be
harmful. The oil could be very hot (burn risk) and some operators
may experience irritation if the oil contaminates exposed skin.
• Check the oil drain plug and its gasket.
• Check the oil filler cap and its 'O' ring gasket.
• Replace any non-serviceable parts.
• Re-install the oil drain plug and tighten firmly.
• Refill the engine with the correct grade of engine oil to the
correct level.
• Refit the oil filler cap.
• Check for leaks and spillages, and deal with as necessary.
Note: Used engine oil should be disposed of in an environmentally
safe way. Check with your Local Authority for the nearest used oil
re-cycling facility.
2. Spark Plug - Checking and replacement
After approximately 50 hours of operation the spark plug should
be removed for checking, cleaning and resetting.
To remove and reinstall the spark plug:
• Ensure that the engine is switched 'OFF' and the fuel tap
is in the 'OFF' position.
