Operation Manual

Refuelling and adding oil to the chain lubrication system
- 33 - ENGLISH 11
6.1 Fuel information
A high performance two-stroke engine
operated with a petrol:oil mixture (petrol + oil =
fuel mixture) or with a special fuel mixture for two-
stroke engines available from specialists powers this
machine.
We recommend the proprietary “Aspen 2-takt”
special fuel mixture. Please observe the special fuel
manufacturer’s instructions.
Information on individual mixing of the fuel mixture
Normal or super unleaded petrol can be used for
individual mixing purposes (minimum octane
number 92 RON).
When using a particularly high quality proprietary 2-
stroke engine oil such as the “SOLO Profi 2T-
Motoröl” which we supply, we recommend an
oil:petrol mixing ratio of 1:50 (2%).
When using other brands of 2-stroke oil we
recommend a mixing ratio of 1:25 (4%).
Only use proprietary 2-stroke engine oil!
Never store fuel mixture longer than 3 - 4 weeks.

Unsuitable petrol or deviations in the mixing ratio
may lead to serious engine damage!
Avoid direct skin contact with petrol and avoid
inhaling petrol fumes - health hazard!
6.2 Fuelling
While fuelling always follow all safety instructions and
take all safety precautions.
Handle fuel only with the engine turned off.
Carefully clean the area around the filler inlet.
Place the machine with the fuel inlet pointing
upwards. Unscrew the tank lid and fill the fuel
mixture up to the lower edge of the filler neck. Use a
funnel with filter to prevent tank contamination. After
filling the tank replace the tank lid and tighten firmly.
6.3 Chain lubrication
Chainsaw oil with an anti-fling additive that
helps the oil adhere to the chain should be
used for lubrication of the saw chain and guide
bar.
Note: You should generally always add the chain oil
whenever topping up with fuel.
If the saw is used regularly we recommend the use
of biodegradable chainsaw oil.
The bio-chainsaw oil available from SOLO
(order no. 00 83 107, 1 litre) has been
awarded the German blue angel symbol for
eco friendliness (RAL UZ 48).
Biodegradable chainsaw oil only has a limited
lifespan and should be used within a period of 2
years from the printed date of manufacture.
Important: If you are planning to not use the saw for
more than 2 months and are using bio-chainsaw oil
then you will need to drain the oil tank and then add a
small quantity of engine oil (SAE 30). Then run the
chainsaw for a while to ensure that all bio-oil residue
has been flushed out from the tank, oil pickup hose
and cutting device. Fill up with bio-chainsaw oil again
when you are ready to take the saw back into
operation again.
(schematic diagram)
To check the chain lubrication, hold the guide bar
over a light-coloured object (e.g. tree stump) and run
the chainsaw at medium speed (approx. half throttle
setting). A light trace of oil forms on the light-coloured
object.
Important: Never work without chain lubrication.
Check the operation of the chain lubrication system
and the level of the oil in the oil tank every time
before you start work. Never re-use old oil.
Notes for new saw chains:
Before installing a new
chain we recommend soaking it in a container (bowl)
with chain oil with anti-fling additives that help the oil
adhere to the chain. Once the chain has been
installed, do not start to cut wood straight away, but
allow the machine to run at part throttle for a while
until a slight oil trail forms on a lightly coloured
background.
