6. CONTROLS AND ADJUSTMENTS
A) FORWARD CLUTCH CONTROL LEVER
This lever only has two positions: engage and disengage. Lowering the lever engages
the clutch and releasing it disengages the clutch. The service brake is connected to this
lever. The brake operates automatically when the clutch is disengaged.
B) ACCELERATOR CONTROL LEVER
This is used to adjust the number of engine revolutions according to the operations to be
carried out. Hence at switch on the lever will be positioned on the minimum setting whilst
during work operations it will be positioned as required by use.
C) PINS TO BLOCK/RELEASE THE FRONT WHEELS
The front wheels can turn freely when the pins are in the disengaged position.
When the pins are engaged in place on the fork supporting the wheel, the front wheels will
only move in one direction. Operate the flail mower with the pins engaged when working on
slopes to prevent the risk of slipping.
WARNING
Before changing direction, release the pins to disengage the front wheels
D) FLAIL ROTOR CLUTCH CONTROL LEVER
This is used to engage and disengage rotary movement of the flail holder rotor. Lowering the
lever engages the clutch and releasing it disengages the clutch. The flail brake is connected
to this lever, so the brake operates automatically when the lever is released and the rotor
stops within a few seconds.
WARNING
The flail rotor rotates at high speed if the engine is running and the flail clutch is engaged,
regardless of the position of the forward clutch.
E and E1) RIGHT AND LEFT WHEEL RELEASE LEVERS
These make directional gear changes easier during forward movement or manoeuvring of
the machine.
WARNING
Never use the release levers instead of the forward clutch control lever since release of the
two wheel release levers at the same time automatically disengages the service brake,
thus overriding its safety function. This precaution must be observed particularly when
working on steep banks.
G) FRONT WHEELS
These are the front support for the machine and they are involved in cutting height adjustment.
