Refuelling and adding oil to the chain lubrication system
ENGLISH 11
6. Refuelling and adding oil to the chain
lubrication system
The tank caps for the fuel tank and the chain lubrication
oil tank are sealed by means of an O-ring. Both tank
closures should only be tightened finger-tight, without
the use of tools.
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.
The fuel mixture can be made up with standard lead-
free petrol or with lead-free premium grade petrol. The
minimum octane rating for petrol is 92 ROZ.
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 Mixing ratio
Always use a fuel:oil ratio of 25:1 (4%) for the first five
tank fillings.
After that we recommend a ratio of 50:1 (2%) with the
use of special two-stroke oil "SOLO 2T engine oil"
which we can supply.
With the use of other brand two-stroke oils we
recommend a ratio of 25:1 (4%).
Never store fuel mixture longer than 3 - 4 weeks.

6.3 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.
6.4 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 above
a lightly coloured object (e.g. a tree stump) and allow
the chainsaw to run in part throttle mode. A light oil trail
should form on the lightly 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.
