SAS filters inspection and cleaning
Remove the two screws «A» from the SAS alumi-
nium cover. Disengage the metallic hose from the
rubber fastener on the cover without detaching the
hose from the sleeve. Remove the plate and the
plastic cover and hence extract the sponge filter
and wash with soap. Dry the filter with compressed
air before refitting, having care to place the plate
in the grooving machined onto the plastic and alu-
minium covers. Upon reassembly, always replace
the O-ring, located on the cover.
Remove the sponge and wash it with soap and
water. Dry it with compressed air before refitting.
Gearbox Oil
− Check for the presence of oil inside the gearbox
(oil capacity ~250 g); with the vehicle axis perfectly
vertical, the oil level must be at the height of in-
spection hole «A».
− To replace the oil, drain the box using filler hole
«B».
− Pour some fresh oil and let the engine run for a
few seconds, hence drain the box again.
− Pour 250 g of fresh oil through hole «A», so that
the level reaches the reference height.
