MAINTENANCE
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
.
5 mm. The
spark plug should be replaced after about a month in
operation or earlier if necessary.
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.
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.
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
mesh
filter.
Wash it clean in warm, soapy water. Allow the filter to
dry and then oil it in according to the instructions.
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.
Oiling the air filter
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.
Gear
There is a plug for filling lubricant on the gear housing.
Use the grease tube to fill with grease and repeat every
25 hours.
CAUTION!
The gear housing must not be filled
completely with grease. The grease expands as the
machine heats up during operation. If the gear housing
was completely filled with grease it could damage the
seals and lead to leakage of grease.
The grease in the bevel gear does not normally need to
be changed except if repairs are carried out.
Cutting unit
Check that the cutting units' screws are fitted correctly.
Tighten them with a tightening torque of 7-10 Nm.
