PR030 ENRICHING ADAPTATION IN OPERATION
PR031 ENRICHING ADAPTATION AT IDLING
RECOMMEND AT IONS No failure must be present or memorized.
Perform the steps for memorizing the adaptation values by the injection
computer.
Erase the computer memory. A t warm, when idling adjustment, observe the se paramete rs :
- If one of t hese parameters is moving towards the minimal limit, there is not sufficient petrol or there
is t oo much air.
- If one of the se paramete rs is moving towards the minimal limit, there is too much petrol or there is
not sufficient air.
(See chapter “ Enriching adaptive correction) for the exact limit values)
Ensure the cleaning condition and the good operation of :
- fuel filter
- fuel pump
- fuel circuit
- fuel tank
- air supply piping
- air filter
- spark plugs
C heck :
- Engine compressions
- Valves cle arance

CHECKING
It is recommended to check the following: -cr acks or breaches of the ba ttery box (c ase)
- battery upper part cleanness
- plugs condition
It is required to strictly check the following:
-lack of plugs sulfate composite
- proceed, is necessary to their cleaning and then greasing with neutral grease;
- correct wiring plugs tightening at the battery plugs. The existence of an imperfect contact
may generate i ncidents at engine starting or a t battery charging, sparks producing risk being
possible to occur, which may cause the battery explosion;
- check the electrolyte level;
- check that a eration holes of the access plugs are not closed.
For the batteries provided with access plugs, which may be dismounted, proceed as follows:
-r emove the plugs;
- check the electrolyte level in each element;
-i f necessary, refill the level, using only distilled water, till maximum 1.5 cm above the
plates;
-check that a eration holes of the access plugs are not closed
ATTENTION !
N ever fill up with electrolyte, but only with distilled wat er.
PRECAUTIONS
It is important to know that: -the battery contains sulfuric acid which is a dangerous substance
- during battery chargi ng, oxygen a nd hydrogen are produc ed, so c heck t hat aera tion
holes of the access plugs are not closed The mixture of these two gases is forming a detonate gas,
which may lead to the explosion risk. 1. DANGER = ACID
The sulfuric acid solution is a very aggressive, toxic and corrosive product. This is a ttacking
the skin, the clothes and may lead to the corrosion of most of the metals. Also, it is very important, that, when you handle a battery , to consider the following precautions:
- protect the eyes by using protective glasses;
- wear anti-acid gloves and clothes.
