The following symptoms may indicate problems that will affect the emissions level of the product:
■ Hard starting or stalling after starting
■ Rough idle
■ Misfiring or backfiring under load
■ Afterburning (backfiring)
■ Black exhaust smoke or high fuel consumption
If you encounter any of these symptoms, have the product inspected and repaired at an nearest authorised service

Possible cause
Engine switch is OFF.
No fuel.
Oil level is low.

Spark plug faulty, fouled, or
improperly gapped.

or draining unleaded fuel, or
refueled with bad unleaded fuel.
Circuit breaker is OFF.
Item plugged in is defective.
An occasional light "knocking" or
"pinging" under heavy load is not
a cause for concern. However, if
the knocking or pinging occurs
under normal load at a steady
engine speed, the problem may
be with the brand of unleaded
fuel being used.
Solution
Turn engine switch to ON.
Fill fuel tank.
Check engine oil level and fill, if necessary.
Turn fuel valve ON.
Replace spark plug.
Move choke lever out to START.
Drain fuel and carburetor. Refuel with fresh
unleaded fuel.

needed.

unleaded fuel.

Try a different item.

service centre.
