use. Check and readjust the tension frequently as a
loose chain can easily derail or cause rapid wear of itself
and the guide bar.

and a quality-proven motor oil for air cooled 2 cycle

container.
Most engine troubles are caused, directly or indirectly,
by the fuel used on the machine. Take special care not
to mix a motor oil for 4 cycle engines.
Use motor oil SAE# 10 W ~30 all year round
or SAE #30~#40 in summer and SAE# 20 in
winter.
Do not use wasted or regenerated oil that
can cause damage to the oil pump.
