Vespa GTS 250 I.E.
Replacement
At 1,000 km and after every 10,000 km, the oil and
the filter must be changed. The engine must be
drained by running off the oil from drainage cap
"B" of the flywheel side gauze pre-filter; further-
more to facilitate oil drainage, loosen the cap/
dipstick "A". Once all the oil has drained through
the drainage hole, unscrew the oil cartridge filter
"C" and remove it.
Make sure the pre-filter and discharge tap O-rings
are in good condition.
Lubricate them and refit the gauze filter and oil
drainage tap, screwing them up to the specified
torque.
Refit the new cartridge filter being careful to lubri-
cate the O-ring before fitting it.
Change the engine oil.
Since a certain quantity of oil still remains in the
circuit, oil must be filled from cap "A". Then start
up the scooter, leave it running for a few minutes
and switch it off: after five minutes check the level
and if necessary top up without exceeding the
MAX level. The cartridge filter must be replaced
every time the oil is changed. Use new oil of the
recommended type for topping up and changing
purposes.
N.B.
THE ENGINE MUST BE HOT WHEN THE OIL IS
CHANGED.
