Spark plug

The spark plug condition is influenced by:
• Incorrect carburettor adjustment.
• An incorrect fuel mixture (too much or incorrect type
of oil).
• A dirty air filter.
These factors cause deposits on the spark plug
electrodes, which may result in operating problems 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 0.65 mm. The
spark plug should be replaced after about a month in
operation or earlier if necessary.
0,65
CAUTION! Always use the recommended spark plug
type! Use of the wrong spark plug can damage the piston/
cylinder. Check that the spark plug is fitted with a
suppressor.

Two-piece shaft

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) on models with two-piece
shafts 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:
• Carburettor malfunctions
• Starting problems
• Loss of engine power
• Unnecessary wear to engine parts.
• Excessive fuel consumption.
MAINTENANCE
Clean the filter every 25 hours, or more regularly if
conditions are exceptionally dusty.
Cleaning the air filter
Remove the air filter cover and take out the filter. Wash it
clean in warm, soapy water. Ensure that the filter is dry
before refitting it.
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.
If the machine is used in dusty conditions the air filter
should be soaked in oil. See instructions under the
heading Oiling the air filter.
Oiling the air filter
Always use filter oil, art. no. 531 00 92-48. The filter oil
contains a solvent to make it spread evenly through the
filter. You should therefore avoid skin contact.
Put the filter in a plastic bag and pour the filter oil over it.
Knead the plastic bag to distribute the oil. Squeeze the
excess oil out of the filter inside the plastic bag and pour
off the excess before fitting the filter to the machine. Never
use common engine oil. This would drain through the filter
quite quickly and collect in the bottom.
Checking and adjusting of throttle
wire
Make sure the throttle cable is tight enough without giving
the product gas and cutting equipment starts rotate. The
throttle cable should not be too loose so the product does
not reached full throttle.
Adjust the nut on the throttle cable with the nut. Then
tighten the lock nut.
