5. HEALTH AND SAFETY INFORMATION
Regular maintenance tasks must be carried out at
specific intervals to retain the engine's performance.
10.1 CLEANING THE AIR FILTER –
FIGS. 30 – 32
A dirty, clogged air filter will restrict the air flow in to
the engine and will cause rough running. It will
increase fuel consumption and may result in starting
problems.
Attention:
Stop the engine before removing the air
filter assembly.
Pull the choke lever
upwards to the closed
position to prevent any debris entering the
carburettor inlet.
Unscrew the retaining bolt
on the air filter
cover
to remove it.
Remove the air filter element
.
Wash the element in warm soapy water to clean
it. Do not use solvents to clean it.
Allow the filter to dry 100% before refitting it on
to the engine.
– Refit cover
.
– Replace the filter if it appears worn or
damaged.
10.2 SPARK PLUG MAINTENANCE –
FIGS. 33 – 34
Over time the spark plug
can become
contaminated. This can be due to adverse running
conditions such as, working with part throttle for a
prolonged period or a fuel mix containing too much
oil. This contamination can build up causing the
engine to run roughly, reduce the fuel consumption
or create starting problems.
Without using any tools so as to avoid damaging
the H.T. lead, remove the lead
from the
back of the spark plug.

– Storing fuels in closed containers. Keeping in mind that fuels may evaporate at room
temperature and collect on the floor of closed rooms (risk of explosion).
– Start the device at least nine metres away from any stored fuels or flammable liquids.
Fuels are toxic, they contain substances that have an immediate toxic effect and may cause
permanent damage to your health. Take all precautionary measures to prevent your body from
absorbing any of these substances:
– Tank and siphon fuels only outdoors or in well-ventilated rooms.
– Do not inhale fuel fumes.
– Avoid contact with eyes and skin.
– Wear gloves when transferring fuel.
– When fuel has come into contact with your clothes, change them immediately. Clean your
clothes before putting them back on.
– Store fuels out of the reach of children.
When handled inappropriately, fuels may cause damage to the environment:
– Transfer fuel carefully. Fuel must never trickle into the ground or the sewage system.
– Dispose of any remaining fuel in an appropriate manner. Never dispose of fuel with regular
household waste.
– Fuels may be stored only for a limited time. Purchase only such quantities that can be used up
within a few months.
