Oil pressure warning light
The vehicle is equipped with a telltale light on the
dashboard that lights up when the key is turned to
the « ON » position. However, this light should
switch off once the engine has been started.
If the light turns on during braking, at idling
speed or while turning a corner, it is necessary
to check the oil level and the lubrication sys-
tem.
Checking the ignition timing
Position the engine at top dead centre (TDC) in
compression. To do this, use the appropriate tools.
Use the holes on the engine crankcase to secure
the tool.
Position the specific tool in the window between
the flywheel pick-up references as illustrated in the
figure.
The arrows stamped respectively on the valve
frame and sprocket must coincide.
N.B.
IF THE TIMING UNIT IS NOT IN PHASE CHECK THE COR-
RECT FITTING OF COMPONENTS.
- As a further verification of the correct distribution
timing, insert a pin into the hole on the gear of the
camshaft and check that it coincides with the spe-
cial blind hole on the frame of the head.
