MAINTENANCE
Two--pieceshaft
The drive shaft end in the lower shaft
should be lubricated with grease every 30
hours. There is a risk that the drive shaft
ends (splined coupling) will seize if they
are not lubricated regularly.
Air filter
The air filter must be regularly cleaned to
remove dust and dirt in order to avoid:
SCarburetor malfunctions
SStarting problems
SLoss of engine power
SUnnecessary wear to engine parts
SExcessive fuel consumption
Clean the filter every 25 hours, or more
regularly if conditions are exceptionally
dusty.

Cleaningthe air filter

Removethe air filtercover and take out the
filter. Wash it clean in warm, soapy water.
Rinse thoroughly. Ensurethat the filter is dry
before refittingit.
An air filter that has been in use for a long
time cannot be cleaned completely. The
filter must therefore be replaced with a new
one at regular intervals. A damaged air
filter must always be replaced.
Spark plug
Thes park plug condition is influenced by:
SIncorrect carburetor adjustment.
SAn incorrect fuel mixture (too much or in-
correct type of oil).
SA dirty air filter.
These factors cause deposits on the spark
plugelec trodes, which may result in operat-
ingpr oblems and starting difficulties.
If the machine is low on power, difficult to
start or runs poorly at idle speed: always
check the spark plug first before taking
any further action. If the spark plug is dirty,
clean it and check that the electrode gap is
0.024″(0.6 mm). The spark plug should be
replaced after about a month in operation or
earlier if necessary.
