Oil and petrol

Oil
Use quality oil only, API
classification TC (TSC-3) which
is offered for air-cooled two-stroke
engines.
Mix the oil for two-stroke engines
according to the instructions
on the container, 1:40 (2,5 %).
Petrol
Danger
!
Under certain conditions petrol
is extremely flammable and
explosive.
– Refuel only in a well ventilated
area and with the engine swit-
ched off. Do not smoke and
switch off all ignition sources
in the vicinity of the tank
or at the fuel storage depot.
– Do not overfill the fuel tank (there
must be no fuel in the inlet
nozzle). After filling up the tank,
ensure that the tank cap
is closed and secured.
– When filling up the tank,
do not spill any fuel.
Spilled fuel or petrol vapours may
ignite. If fuel has been spilled,
ensure that the area is dried
before the engine is restarted.
– Prevent repeated or prolonged
skin contact or inhalation
of the vapours.
