B Filling with chain oil
• All our chain saws have an automatic chain lubrication
system. On some models the oil flow is also adjustable.
• The sizes of the chain oil tank and fuel tank have
been chosen so that the saw will run out of fuel
before running out of oil.
However, this safety feature requires that you use the
right sort of chain oil (if the oil is too thin it will run out
before the fuel), and that you adjust the carburettor
as recommended (a weak mixture may mean that the
fuel lasts longer than the oil). You should also use the
recommended cutting equipment (a bar that is too
long will use more chain oil).
The above conditions also apply to models with an
adjustable oil pump.
Always wear gloves, when working with the
chain, in order to protect your hands from
injury.
Check that the chain brake is in disengaged position
by moving the front hand guard towards the front
handle.
Take off the bar nuts and remove the clutch cover.
Fit the bar over the bar bolts. Place the bar in its
rearmost position. Place the chain over the drive sprocket
and in the groove on the bar. Begin on the top side of
the bar. Make sure that the edges on the cutting links
are facing forward on the top side of the bar.
Fit the clutch cover and locate the chain adjuster pin in the
hole on the bar. Check that the drive links of the chain fit
correctly on the drive sprocket and that the chain is in the
groove on the bar. Tighten the bar nuts finger tight.
Tension the chain by using the combination wrench. Turn
the chain adjuster screw clockwise. The chain should be
tensioned until it fits snugly on the underside of the bar.
Hold up the tip of the bar and tighten the 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 wrench.
When fitting a new chain, the chain tension has to be
checked frequently until the chain is runin. Check the
chain tension regularly. A correctly tensioned chain
gives good cutting performance and long lifetime.
IMPORTANT!
The chain saw is equipped with a two-
stroke engine and must always been run using a mix-
ture of petrol and two-stroke engine oil. It is impor-
tant 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 inac-
curacies can drastically affect the ratio of the mixture.
Petrol
• Use good quality 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.
• When working with continuous high revs (e.g.
delimbing) a higher octane grade is recommended.
Two-stroke oil
• For the best results use PARTNER two-stroke oil,
which is especially developed for chain saws.
Mixing ratio 1:50 (2%).
• If PARTNER two-stroke oil is not available, you may
use another two-stroke oil of good quality that is
intended for air cooled engines. Contact your deal-
er when selecting an oil. Mixing ratio 1:33 (3%)-
1:25 (4%).
• Never use oil intended for four-stroke engines.
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 fill-
ing the saw’s fuel tank.
• Do not mix more than approx. 1 months supply of fuel.
• If the saw is not used for some time the fuel tank
should be emptied and cleaned.
Chain oil
• The chain lubrication system is automatic. Always
use special chain oil with good adhesive charac-
teristics.
• In countries where no special chain oil is available,
EP 90 transmission oil can be used.
• Never use waste oil. This results in damage to the
oil pump, the bar and the chain.
• It is important to use oil of the right viscosity
according to the air temperature.
• In temperatures below 0oC (32oF) some oils
become too viscous. This can overload the oil
pump and result in damage to the oil pump com-
ponents.
• Contact your servicing dealer when choosing chain oil.
