Fuel filter
m NOTICE
Never use the saw without a fuel filter. The fuel fil-
ter must be cleaned after 100 operating hours or re-
placed if damaged. Empty the fuel tank completely
before replacing the filter.
1. Ensure that the stop switch is set to stop (0).
2. Remove the top cover and the spark plug con-
nector.
3. Remove the tank lid (fig. 21 / item K).
4. Bend a soft wire into shape.
5. Insert it into the fuel tank's opening and hook it
onto the fuel hose. Pull the fuel hose carefully to-
wards the opening until you can grasp it with your
fingers.
m NOTICE
Do not pull the hose out of the tank completely.
6. Lift the filter out of the tank.
7. Turn and remove the filter, and clean it. (If it is
damaged, dispose of the filter and replace it with
a new one.)
8. Place the end of the cleaned or new filter on the
fuel hose. Insert one end of the filter into the tank
opening. Ensure that the filter is located in the
bottom corner of the tank. If necessary, use a
long screwdriver to move the filter into the correct
position but ensure that you do not damage it.
9. Fill the tank with a fresh mixture of fuel and oil.
See the "Fuel and oil" section.
Put the fuel tank lid back on.
Spark plug (fig. 24b)
m NOTICE
In order to ensure that the chainsaw motor remains
efficient, the spark plug must be clean and have the
correct electrode gap (0.6 mm). The spark plug must
be cleaned or replaced every 20 operating hours.
1.
Set the stop switch to stop (0).
2.
Remove the top cover.
3.
Remove the spark plug connector (fig. 15 / item
D) from the spark plug (E) by pulling and turning
it at the same time (fig. 15).
4.
Use the spark plug spanner to remove the spark
plug (fig. 1 / item 22). DO NOT USE ANY OTH-
ER TOOLS.
5.
Use a copper wire brush to clean the spark plug
or insert a new spark plug.(fig. 24). Then re-at-
tach the top cover.

Maintaining the bar (fig. 25)
The bar (the guide rail for the chain and teeth) must
be oiled on a regular basis without exceptions. The
maintenance to the bar described in the following
section is required to ensure optimum saw perfor-
mance.
m NOTICE
The teeth on a new saw were oiled in advance in the
factory. If you do not oil the bar's teeth as described
below, performance is reduced and seizures occur,
rendering the manufacturer's warranty invalid.
Oiling the teeth
If the saw is used intensively, the bar's teeth (Z2)
must be oiled regularly (once per week).
To do this, first clean the 2 mm hole at the tip of the
bar (Z1) and then press a small amount of multi-pur-
pose grease into it.
Multi-purpose grease and grease guns are available
from specialist shops.
m NOTICE
The saw chain does not have to be removed to oil the
bar's teeth. Oiling can be carried out when working
with the motor switched off.
m CAUTION
Always wear high strength gloves when handling the
bar and the chain.
This can prevent most problems with the bar, as the
chainsaw is kept in a well maintained condition. A bar
that is not oiled sufficiently and operating the saw
with a chain that is TOO TIGHT contribute to faster
wear. To minimise wear on the bar, we recommend
the following steps to maintain it.
m CAUTION
Always wear protective gloves during maintenance
work.
Do not maintain the saw when the motor is still hot.
Turning the bar
The bar should be reversed every 8 working hours in
order to guarantee that is wear evenly.
Always keep the bar's groove and oiling hole clean
(fig. 25).
Check the bar's rails for wear on a regular basis, re-
move burrs and straighten the rails with a flat file (not
supplied as standard).
