Aircompressor - Porsche 928 1980 Owner's Manual

Collapsible spare tire
The collapsible spare tire is located under-
neath the luggage compartment. It is cover-
ed by a lid with a quick release catch. The car
jack is stored behind the spare tire. Stored
inside the wheel rim is the electric air com-
pressor kit. This kit also includes a plastic
cover for the road wheel to keep luggage
compartment or car interior clean.
Due to tread and space saver design fea-
tures of the collapsible tire, car handling may
be affected.
Therefore, do not drive more than 50 mph
or 80 km/h when using the collapsible
spare tire. It is for emergency use and
short distances only. Use the original
road tire as soon as possible.
Inflating the collapsible tire
Inflate the collapsible tire with the electric air
compressor that comes with your Porsche.
Do not use other equipment!
1. Install spare wheel before inflating the
tire.
2. Attach hose of air compressor to tire valve
and insert plug of electric cord into ciga-
rette lighter socket.
3. The required tire pressure is 32 psi or
2.2 bar. Check pressure with tire pressure
gauge.
4. Have flat road tire repaired and remount-
ed on car at next service stop. Remember,
the collapsible tire is for emergency use
and short distances only.
When the air is released from the collaps-
ible tire, it will return to its original shape after
cooling down for several hours. Store col-
lapsible tire in compartment underneath the
luggage compartment.
The collapsible spare tire cannot be re-
paired or mounted with standard work-
shop equipment. Repair and remounting
must only be done by the manufacturer.
Tire tread depth
As required by law, the tread depth of the
collapsible tire is the same as that of the
original equipment tire. Replace a worn col-
lapsible spare tire in time.
If air compressor does not work
... Check if tobacco or any other foreign
matter is lodged in the cigarette lighter
socket. Remove carefully with a wooden
pick. Do not use metal object to prevent
short circuit.
... Check if fuse is blown. Replace with new
equivalent fuse.
Maintenance of air compressor
The air compressor is maintenance-free. Do
not apply oil or any other lubricant.
The air filter should be cleaned periodically
to assure maximum efficiency of the unit.
