ALPHA
Steering
The steering on the ALPHA can be set in two different
modes:
Front wheel steering - to be used on the road and dur-
ing spraying
Four wheel steering - to be used during turning at the
end of the tram lines
WARNING! Do not use 4-wheel-steering on
public roads, and fast driving. Always
disengage the 4-wheel steering before entering
public roads.
In case of failure in the hydrostatic steering circuit the
steering orbitrol permits an operation of the steering in a
closed circuit.
Front Wheel Steering
In this mode, only the front wheels can turn, the rear
wheels stay in straight position.
To select Front Wheel Steering mode:
• Set the switch on ‘
AUTO’
• Turn the steering wheel so that the rear wheels are
placed in right position; the signal AR is activated.
Four Wheel Steering
In this mode, the front and rear wheels are steering op-
posite each other simultaneously.
Spraying
Before taking the sprayer into operation
Although the sprayer has been applied with a strong
and protective surface treatment on steel parts, bolts
etc. in the factories it is recommended to apply a film of
anti-corrosion oil (e.g. CASTROL RUSTILLO or SHELL
ENSIS FLUID) on all metal parts in order to avoid
chemicals and fertilizers to discolourate the enamel.
Avoid to apply oil on windows, lamps, markings and rub-
ber parts.
Spraying circuit operating diagram
To engage 4-wheel-steering mode:
• Set switch to
“AUTO”
• Turn the steering wheel until both alignment lamps,
AV and AR , lights
• Step on the 4-wheel-steering pedal on the floor
• Keep the pedal depressed as long as 4-wheel-steer-
ing is required
To disengage 4-wheel-steering mode:
• Step off the 4-wheel-steering pedal
• Turn the steering wheel until the lamp
AR lights
The steering is now back to 2-wheel-steering.
NOTE! If the AUTO/MAN switch is set in MAN mode,
the wheel alignment must be done manually. The di-
odes indicate the wheels are aligned. In MAN mode an
adapted crab steering can be done by using the steer-
ing wheel and pedal.
