2.2.33. Air cleaner
Air cleaner is mounted on the engine to purify the air for combustion.
The intervals at which the air cleaner requires servicing depend on the specific operating conditions
encountered. Clogged air filters may cause black smoke and reduce power.
A check should be made from time to time to see that the fastening elements securing the air cleaner
to the intake manifold seal the connection tightly. Any ingress of unfiltered air is liable to cause a high
rate of cylinder and piston wear.
2.2.34. Electrical equipment
1) Alternator
The alternator is fitted with integral silicon rectifiers. A transistorized regulator mounted on the
alternator body interior limits the alternator voltage. The alternator should not be operated except
with the regulator and battery connected in circuit to avoid damage to the rectifier and regulator.
The alternator is maintenance-free, nevertheless, it must be protected against dust and, above all,
against moisture and water.
Operate the alternator according to
the instructions given in the chapter
“Commissioning and operation”.
