Operating instructions

DESCRIPTION
Lighting
The lighting on the car consists of two headlights (mainbeam and dipped)
together with two combined flasher and parking lights. The rear lighting
consists of two tail lights including flashers, combined lamps for the tail lights
and brake warning lights as well as the reversing light.
Internal lighting consists of a roof light above the rear view mirror and a light
for the parcel shelf.
See pages 40-42 concerning replacement of bulbs.
Fuses
The electrical system is protected by means of fuses fitted in a fusebox to the
left on the bulkhead under the bonnet. When replacing a fuse, be sure that you
use one with the right rating. If any fuse should blow repeatedly, do not fit
a more powerful fuse. Instead, have a workshop check the electrical system.
Power transmission
Clutch
The clutch is of the single dry plate type with diaphragm spring. The diaphragm
spring functions partly as a lever when declutching and partly as a pressure
spring when engaging. Clutch pedal pressure is transmitted mechanically to
the release fork.
Gearbox
The gearbox is used to regulate the speed ratio between the engine and the rear
axle so that the engine always operates in its most favourable speed range. The
gearboxes are fully synchronized. The M 40 gearbox is four-speed.

DESCRIPTION
Propeller shaft
The propeller shaft, which is the connecting link between the gearbox and the
rear axle, is divided into two sections. The front section is journalled at its rear
end in a bearing housing consisting of a rubberized ring.
Rear axle
The engine driving power is transmitted via the propeller shaft to the rear
wheels through the rear axle. The rear axle is of the hypoid type, that is, the
drive pinion is below the centre line of the drive shafts.
On certain markets, the rear axle is fitted with a differential brake as extra
equipment. The function of the differential brake is to transfer automatically
the pulling power to the wheel with the best grip on the road surface when
one of the wheels begins to skid. Except for the differential, the rear axle is
similar to a conventional rear axle.
Brakes
The brake system is of the two-circuit type with disc brakes front and drum
brakes rear. The system is provided with a tandem-type master cylinder and a
directly-operating booster cylinder.
The principle of the two-circuit system is that both front wheels are connected
to a rear wheel. Should there be a failure in one of the circuits there is always
braking power on both front wheels and the other rear wheel. The pressure
lines to the rear wheels are fitted with relief valves which prevent involuntary
locking of the rear wheels.
This system has a warning light located on the instrument panel. The warning
light shows if there is a failure in one of the circuits when braking. It also serves
as a warning light for the handbrake.
Wheels and tyres
The car has pressed steel wheels with lugs for the attachment of the hub caps.
All wheels are carefully balanced and the tyres are of the tubeless type. Tyre
size: 165 S 15, or 165 SR 15.
