POLICY OF CORRECT USE FOR PROXIMA POWER TRACTORS
3 – with the clutch pedal
Depressing the clutch pedal deactivates the engine clutch.
Releasing the clutch pedal activates the engine clutch.
The activation speed of the engine clutch depends on how fast the clutch pedal is released.
The clutch pedal does not have the function of automatic acceleration and the speed and smoothness of acceleration is
influenced by the driver.
In ordinary operation, the clutch pedal should only be used to stop the tractor.
For precise subtle movements, e. g. when connecting tools or when operating the tractor in limited space, and
only when reduced gears do not suffice for slow movement, the clutch pedal may be used for a short time.
It is forbidden to partly depress the clutch pedal to regulate speed when the rotation
of the engine is higher than 1,000 RPM.
Do not use the clutch pedal as a foot support.
Breaking these rules may lower the durability of the clutch pedal or may cause mal-
function of the engine clutches
DISCONTINUOUS AUDIO WARNING SIGNAL
If the speed is regulated by partly depressing the clutch pedal and the rotation of the engine
is higher than 1,000 RPM a discontinuous audio warning signal goes off and the
gearbox error indicator lights up. If this happens, either depress the clutch pedal to
the bottom stop point immediately or completely release the clutch pedal and wait
until the audio warning signal quiets and the gearbox error indicator goes out. Lower
the rotation of the engine below 1,000 RPM and continue the operation of the tractor.
If this is not done after 8 seconds of intermittent acoustic warning signal goes on unin-
terrupted
