a
aRemove the seal(s) of the throttle valve.aHold the throttle valve flap open manually.
aSpray CARBURETTOR CLEANER (see Vehicle:
Parts and consumables for the repair) (04B, Con-
sumables - Products) into the air vent until all traces
of clogging have disappeared. Equipment required
compressed air nozzle
IMPORTANT
Wear leaktight gloves (Nitrile type) for this opera-
tion.
IMPORTANT
Always wear protective gear (gloves, goggles and
breathing masks).
Note:
Be sure to work in a clean environment so as not to
allow any contamination of the throttle valve.
Note:
The CARBURETTOR CLEANING product dam-
ages the seals.
