Is there a spark
from the spark plug?
Is the fuel tap
in the down position?
Is 10w30
oil being used?
Make sure fuel tap
is pointing
downwards.
Is the oil level
correct?
Is the choke in the
correct position?
Always use 10w30 grade
oil. If other oil has
been used by mistake,
drain and replace.
Check oil dipstick
and top up
if required.
Ensure choke is in the
correct place.
Refer to starting methods.

PROBLEM SOLUTION
Generator will not start. • Check fuel valve tap is in the ‘down’ position.
• Check the oil level is correct.
• Check 10W30 oil is being used.
• Check choke is in the correct position (refer
to starting methods).
• Check there is a spark - Remove your HT
(high tension) lead from the top of your spark
plug. Remove the spark plug and reconnect
the lead, then touch the metal on the spark
plug against the generator frame. Gently
pull the starter cord mechanism, listen for an
audible ‘ticking’ sound and/or small flashes
coming from the very tip of the spark plug.
If there is no audible ‘ticking’ and/or small
flashes, the spark plug may need replacing.
Generator is difficult to
start.
• The air filter is dirty - clean the filter
• The fuel filter is dirty - clean the filter
• If the pull start mechanism is too ‘hard’ when
trying to pull it, it may denote that there is
too much oil. Check the oil level by using
the dipstick and drain excess oil from the oil
sump bolt at the bottom of the generator.
• If the pull start mechanism feels too ‘slack’
(i.e easy to pull), there may be not enough
compression in the generator engine for it to
work properly. Please contact SGS Engineer-
