Lubrication and Maintenance
Maintenance Schedule
Regular maintenance is necessary to ensure optimum performance and extend the service life of the unit.
The table below shows the items that require regular maintenance and the frequency at which each
should be serviced.
Ensure that the engine is stopped before you begin any maintenance or repairs. This will avoid the
possibility of carbon monoxide poisoning from the exhaust fumes. Be sure that there is adequate
ventilation whenever you operate the engine.
To avoid burns from hot parts let the engine cool before touching it.

Engine Oil Change
Drain the oil when the engine is warm to ensure
quick and complete draining.
Place a suitable container beneath the drain plug.
Remove the dipstick and drain plug and allow the
oil to drain completely in to the container.
Reinstall the drain plug and tighten securely.
With the engine level, fill the sump through the
dipstick opening with a high detergent, premium
quality SAE 10W-30 engine oil, until it is level with
the edge of the filler neck. Oil capacity is 0.6 litres.
Reinstall the dipstick and tighten.
Dispose of the used oil in a manner consistent with
protecting the environment. Take it to a service
station or recycling depot for proper disposal.
