6.2 STARTING SYSTEM
GENERAL INFORMATION
The starting system is built into the upper conveyor
(which also includes the tank) and consists of a
cable wound onto a pulley.
The movement from the pulley to the flywheel (and
the engine shaft) is transmitted by a pair of hooks.
The cable is returned and rewound by a spiral
spring.
Other than the possibility of the cable breaking, the
starting system may malfunction in the following
ways:
• failed start after attachment (if not due to other
causes):
= cable too short, therefore does not supply
adequate number of revs to the engine [
6.2.A] .
• the pulley is not attached to the flywheel. This
can be detected when the cable unwinds with-
out strain :
= the hooks are deformed or broken
[ 6.2.B] .
• inefficient or no return of the cable:
= spring broken
[ 6.2.C] .
In all cases, remove the conveyor to make the nec-
essary checks or repairs.
SERVICING PROCEDURES
A) Replacing the cable
1 Remove the conveyor with the tank [ 6.1.A] .
2 Remove the internal screen (1) fastened by the
screw (2).
3 Keep hold of the pulley (3) and slowly unwind
(clockwise) the entire cable (4) to gradually
release the return spring. If the cable breaks, the
spring will be already released and you will only
have to unwind the cable.
4 Undo or cut the knot at the end of the cable or
remove the section still attached to the pulley.
5 Cut a section of cable (4) (Ø 4.5 mm and 2.40 m
long), fit one end in the pulley hole (3) and make
a knot to prevent it from slipping out.
