Adjusting the bar
FIG. 35
The bar must be adjusted so that it is parallel with the
log bolsters and with the rails. This is done using the
nuts under the vibration damping plate. Set the bar so
that it is parallel with the rails by positioning a straight
ruler measuring approximately 1 m across the bar.
Then place a board between the log bolsters on the
rails. Adjust with the two inner adjustment nuts, so that
the distance between the board and the ruler is the
same. Using the nuts under the vibration damping
plate, the ruler (FIG. 35) can be adjusted so that it is
parallel (has the same dimensions at both ends).
Then adjust the bar so that it is parallel with the log
bolsters (FIG. 36). Adjust using the outer adjustment
nut until the distance between the log bolsters and the
bar is the same along the entire length of the bar. Then
tighten the locking nuts. Check the setting once more.
To achieve the optimum result, it is very important to
ensure that these settings are performed accurately.
This prevents the timber being at an angle or the bar
catching.
FIG. 36

Checking the bar
FIG. 37
On a one-man sawmill with electric motor, the
parallelism of the bar is set in the factory. To ensure
that this setting has not been altered during transport
and installation, the setting (FIG. 37) should be
checked when the sawmill has been installed in
accordance with the instructions for the one-man
sawmill with chain saw engine. Adjust the bar using
the adjustment screws on the console’s plastic guides.

2. Can cause skin irritation.
3. Is highly inflammable.
The following are absolutely forbidden when fuelling:
•
•
Smoking.
To have flames or hot objects in close
proximity.
•
To have the engine running.
Petrol
CAUTION! The one-man sawmill, which is equipped
with a two-stroke engine, must always be run on a
mixture of petrol and two-stroke engine oil. It is
important to accurately measure the amount of oil to
be mixed to ensure that the correct mixture is
obtained. When mixing small amounts of fuel, even
small inaccuracies can drastically affect the ratio of the
mixture.
Always provide for good ventilation
when handling fuel.
!
Use good quality unleaded or leaded petrol. The
lowest octane recommended is 90. If you run the
engine on a lower octane grade than 90 so-called,
knocking can occur. This gives rise to a high engine
temperature, which can result in serious engine
damage.

Mixing
• Always mix the petrol and oil in a clean container
intended for fuel.
• Always start by filling half the amount of the petrol to
be used. Then add the entire amount of oil. Mix
(shake) the fuel mixture. Add the remaining amount
of petrol.
• Mix (shake) the fuel mixture thoroughly before filling
the saw’s fuel tank.
• Do not mix more than max. one month’s supply of
fuel.
• If the saw is not used for some time the fuel tank
should be emptied and cleaned.
Fuelling
1.Clean around the fuel cap.
2.Open the fuel cap slowly so that any excess
pressure is released.
3.Tighten the fuel cap carefully after fuelling.
Clean the fuel tank regularly. The fuel filter should be
changed at least once a year. Contamination in the
fuel tanks causes malfunction. Make sure the fuel is
well mixed by shaking the container before fuelling.

MAINTENANCE
Saw chain
WARNING!
The chain is sharp and can cause
cuts. It can cause personal injury
when handled carelessly. Always
wear protective gloves when
working with the saw chain.
!
The chain is correctly tensioned when there is no slack
on the underside of the bar, but it can still be turned
easily by hand. Hold up the bar tip and tighten the bar
nuts with the combination spanner. When fitting a new
chain, the chain tension has to be checked frequently
until the chain is run-in. Therefore check the chain
tension regularly. A correctly tensioned chain means
good cutting performance and a long lifetime.
The chain should be sharpened regularly to give
optimal performance. During normal sawing of most
species of wood this should be done at intervals of
approximately 2 hours effective cutting time (i.e. the
time that the saw chain is actually working). The chain
should be sharpened more frequently when cutting
those species of wood with a high sand content. A
special file gauge (article no. 504 98 16-78) is
available as an accessory for sharpening the saw
chain. The file gauge may be ordered from your dealer.
Adjusting the bar
When replacing the bar and chain, the position of the
bar may be altered. In order to eliminate poor cutting
results, the adjustment of the bar should be checked
(see Adjusting the bar, page 20).
