Maintenance
Running combustion engines in confined areas CAN KILL IN MINUTES. Engine exhaust fumes contain carbon-
monoxide – a deadly gas that you cannot smell or see. NEVER run a combustion engine in confined areas
EVEN IF windows and doors are open. ONLY run combustion engines OUTDOORS and away from doors,
windows and vents. • Petrol/fuel/gasoline is extremely flammable – keep clear of naked flames or other
ignition sources. • Do not have the engine running during inspection and maintenance unless specifically required. • The engine should be cool
enough to touch before performing maintenance activities. • Some maintenance activities described may be beyond the scope of some users.
For procedures that you are not comfortable with or have the tools or experience for, have the unit serviced by a service centre or qualified
technician.

To keep the machine performing at optimal efficiency, regular checks and maintenance is required. Proper care and maintenance ensures best
performance and longest service life.
The maintenance schedule below specifies preventative maintenance checks and necessary maintenance tasks and how often they should be
performed. The schedule applies to multiple engines; some engines may not include some components, so maintenance on those components is
not applicable.
Harsh operating environments such as extreme temperatures, dust etc may necessitate more
frequent maintenance. • Maintenance frequencies are based on general factors including a maximum use of approximately 300
hours per year. Apply common-sense when following the maintenance schedule based on your actual use of the product. • Keep
reasonable records of maintenance activities for reference.
Failure to follow the maintenance schedule, using incorrect or non-
compatible accessories or replacements parts, or general negligence may result in making the product warranty void.
