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 runni

ng during inspection and maintenance unless specifically required. • The engine

should be cool enough to touch before performing maintenance activities. • Some maintenance activities
may be beyond the scope of some users. Do NOT attempt procedures that you are not comfortable with, or
do not have the necessary tools, experience or knowledge for

– take the unit to an authorised service centre

or qualified technician for servicing. • Harsh operating environments such as extreme temperatures, dust etc
may nece

ssitate more frequent maintenance. •

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

To keep the machine performing at optimal efficiency, regular checks and maintenance is required. 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.

Maintenance Schedule

Use the following maintenance schedule for a list of regular maintenance tasks and how often they need to
be performed. Maintenance frequency is based on average usage. Be aware of how much the machine is
used and be sure to follow the schedule according to time or usage, whichever comes first.

Towards the end of this document is a form you can use for maintenance record keeping. It is recommended
that you keep a reference of all maintenance.

Major Servicing and "Heavy-Duty" Usage

- For engines that are subject to "heavy-duty" use,

which can be defined as being used under loads of 85% or more and / or in use more than

approximately 300 hours per year (for example, generators and water pumps), more frequent "Major
Service" maintenance is required. In addition to normal service requirements, and as with many smaller
machine and off-road bike engines, the following parts (as applicable for petrol, diesel or 2-stroke engines)
may require replacement during a major service:
• Piston rings.
• Big-end bearings.
• Small-end bearings.
• Gudgeon pin.
• Oil rings.
• Gaskets and seals.
• Valve seats.
Inspection of the following items is required:
• Piston for cracks and stress fractures.
• Bore for wear requiring reconditioning.
• Full machine for broken, worn or loose parts.

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
