6.7 TURNING OFF AND STOPPING THE ENGINE
GENERAL INFORMATION
The engine is turned off and stopped by releasing a
lever on the lawnmower. The cable acts on a lever
which simultaneously activates a microswitch that
sends the coil to earth as well as a brake which acts
on the flywheel.
The brake must be able to stop the engine within 3
seconds after it is turned off.
The system for turning off and stopping the engine
can malfunction in the following ways:
• the engine does not start:
= brake cable broken or disconnected [
6.7.A
];
= faulty switch [ 6.7.B
];
= earth cable has deteriorated.
• the engine does not turn off:
= brake cable bent or jammed [ 6.7.A
];
= faulty switch or disconnection [ 6.7.B
].
• the engine does not stop within 3 seconds after
it is turned off:
= clutch lining has come away [ 6.7.C
].
If the microswitch malfunctions or if the brake lining
has come away, replace the entire assembly which
is mounted on a supporting bracket.
For access to the system for turning off and stop-
ping the engine, remove the upper conveyor.
SERVICING PROCEDURES
A) Checking the control cable
1 Check that the sheath (1) is not bent, that the

mower lever and the external hole of the lever
(3) on the engine and that the terminal (4) is cor-
rectly fastened to the support (5).
