Checking the calibration
Switch the device on (button E).
Position the calibration spring plate (Z) on the sensor as shown on the diagram (checking value engraved to-
wards the top, (A) minimum value, (B) maximum value).
Tighten the adjusting button (1) until it goes "CLICK - CLICK - CLICK".
Check that a value X between the values (A and B) (A ≤ X ≤ B) is displayed.
Note: it may be necessary to perform several preliminary tests in order to obtain the correct value.
If the correct value if still not obtained after several attempts, contact SEEM.
NOTE : each device has its own calibration spring plate and they are not interchangeable.

GENERAL INSTRUCTIONS:
- Never refit a belt which has been removed, re-
place it.
- Never retighten a belt for which the tension
reading is between the fitting value and the
minimum operating value.
- When checking, if the tension is below the mi-
nimum operating value, replace the belt.

SPECIAL NOTES FOR VEHICLES FITTED WITH A
DRIVER’S AIRBAG
IMPORTANT
To avoid any risks of destroying the rotary switch
under the steering wheel, comply with the
following instructions:
• Before removing the steering column and the
rack, the steering wheel MUST be immobilised
with the wheels straight using a "steering
wheel locking" tool, throughout the whole
operation.
• Any doubts about whether the steering wheel
is centred means that the steering wheel will
have to be removed so that the centring
method described in section 88 "Airbag" can
be applied.
REMINDER: in this case, only qualified, trained
staff can carry out this operation.
NOTE: cut the base of tool Mot. 1159 to 30 mm.

CHECKING THE FUEL SUPPLY PRESSURE
SPECIAL TOOLING REQUIRED
Mot. 1311-01 Fuel pressure test kit
Disconnect the fuel supply pipe (1) from the
throttle body and insert the0 - 10 bars pressure
gauge and the three way union from the test kit
Mot. 1311-01.

The pressure should be 1.06 bar.
Checking the pump safety valve
If the fuel pressure is correct, feed the fuel pump
and clamp the pipe with the two position valve
for a brief moment. The pressure should stabilise
at approximately 3 bars.
