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.
7. When fitting a new chain, the chain tension has to
be checked frequently until the chain is run-in.
Check the chain tension regularly. A correctly
tensioned chain gives good cutting performance
and long lifetime.

Fuel and fueling
Fuel
WARNING
Gasoline is very flammable. Avoid smoking or bringing
any flame or sparks near fuel. Make sure to stop the
engine and allow it cool down before refueling the
machine. Select well-ventilated outdoor bare ground for
fueling and move at least 3 m (10 ft) away from the
fuming point before starting the engine.
NOTICE
The chain saw is equipped with a two-stroke engine,
and it is certified to operate on unleaded gasoline and
two-stroke air cooled engine oil at a recommended mix
ratio of 40:1. It is important to accurately measure the
amount of oil to be mixed to ensure that the correct
mixture is obtained. When mixing small amount of fuel,
even small inaccuracies can drastically affect the ratio
of the mixture.
40:1
Gasoline: Use good quality unleaded or leaded petrol.
Gasoline may contain up to 10% Ethanol (grain alcohol)
or 15% MTBE (methyl tertiary-butyl ether). Gasoline
containing methanol (wood alcohol) is NOT approved.
•
Poor quality gasoline or oil may damage sealing rings,
fuel lines or fuel tank of the engine.
