Troubleshooting
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. 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
. • 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.
The following information may assist in identifying a problem and rectifying it.
Cannot attach grass catcher.
Possible Fault
Action
Handle installed incorrectly
For models that do not have spigots on the handle mounting brackets, ensure the handle is
installed against the outer face of the mounting brackets.
Difficulty starting the engine.
Possible Fault
Action
Lack of fuel
Check that there is fuel in the tank and the fuel system is primed (if applicable). • To further
check if fuel is reaching the carburettor, remove the carburettor drain plug and check if fuel
drains.
Engine “OFF”
Ensure engine ON/OFF switch is in the “ON” position (if applicable).
Carbon build-up on spark plug
Remove the spark plug and clean any carbon from the electrodes before re-installing it.
Spark plug faulty
Remove the spark plug, then reconnect the plug lead to it. Place the engine ON/OFF switch
in “ON” position (if applicable). Touch the spark plug electrode to a part of the engine
crankcase, away from the spark plug hole, and attempt to start the engine – a spark should
be visible across the electrodes as the engine is rotated. If no spark is visible, replace the
spark plug.
Engine “flooded” with fuel
Place the choke in “HOT” or “RUN” position. Leave the ON/OFF switch in the “OFF” position
(if applicable). Pull the starter cord several times to assist clearing excess fuel from engine
before attempting to start engine.
Not enough or too much engine oil
Check oil level and ensure that the level is at or just below the recommended maximum
level.
Engine starts but does not idle.
Possible Fault
Action
Blocked air filter
Check and clean the air filter.
Idle speed requires adjustment
Adjust idle speed until engine runs smoothly and at a reasonable speed when idling.
