Starting the engine
1. Switch on the battery isolator switch.
2. Ensure pilot lever is in neutral and parking brake is
activated. A safety start switch will disable the starter
motor when the pilot lever is not in neutral.

3. Set throttle at
/
of full speed.

4. Switch on key to pos. 1 and check warning lamps.
5. Check that the spraying pump and on/off valve at
EC-operating unit is switched off.
6. When the preheating control lamp is off, turn the key
to start position.
7. Set throttle to 1000 r.p.m. and let the engine warm up
for 3 min. to ensure good lubrication before driving.
To stop the engine
1. Set the pilot lever in neutral position and apply park-
ing brake.
2. Let the engine run idle (800-1000 r.p.m.) for 5 min. to
cool turbo and engine before stopping.
3. Stop engine by turning key to position 0.
4. Switch off the battery isolator switch.
WARNING! When parking, always ensure that
the sprayer is out of reach of children or others,
who can get contaminated and injured by
chemical residues left at, or in the sprayer!
Propulsion
The sprayer is equipped with hydrostatic transmission
with full time 4-wheel-drive.
The speed can be varied stepless forward and reverse
with the pilot lever.
The transmission has two different speed ranges which
can be set independently on the front and the rear axle:
1. Low speed / high torque range. 0 - 12.5 km/h
2. High speed / low torque. 0 to 25 km/h.
3. Different setting on front and rear axles. 0-18 km/h.
Range 1 is used for spraying in the field and when
working speed and full traction power is required.
Range 2 is used for road transport when the full speed
and less traction power is required.
Range 3 is used when driving uphill in slippery condi-
tions where change in weight distribution will cause
spinning front wheels.
IMPORTANT! Range 3 should not be used for continu-
ous driving. When conditions are back to normal, switch
to range 1 again. NEVER change range when machine
is moving.
To select speed range:
• Stop driving by moving the pilot lever to neutral
• Set the speed selector switches forward for slow
speed range
• Set the switches backwards for fast speed range
1: Switch front wheels
2: Switch rear wheels
Slow range:
0 - 12.5 km/h
Fast range:
0 - 25 km/h
Medium range: 0 - 18 km/h
To avoid wheels spinning:
• Set the speed selector on "High" speed (Hare)
on the axle with spinning wheels
• Set the speed selector on "Low" speed (Tortoise)
on the axle with non-spinning wheels
• As soon as the conditions are back to normal, set
both selectors to "low" again
IMPORTANT! The engine r.p.m. must always be mini-
mum 1800-2000 r.p.m. to ensure full traction and brak-
ing power of the transmission. Driving with too low en-
gine r.p.m. can cause braking failure and transmission
damage!
Braking
The ALPHA has no actual serv-
ice brake system. The hydrostatic
transmission works as propulsion
and service brake system in one.
To stop the machine, the pilot le-
ver is moved towards neutral "0".
The parking brake is placed on
the side of the lateral switch
board/console.
The brake is engaged when the
handle is pushed upwards.
IMPORTANT! Never activate the parking brake when
the self-propelled sprayer is moving!
Electronic anti-spin, SAPE (if fitted)
The SAPE will prevent wheel spinning under difficult
field conditions - especially uphills with uneven axle
loads.
A wheel speed sensor on each wheel will report if the
speed on one wheel will increase more than 15%, and
the oil supply to this wheel will be reduced by an elec-
tronic controlled hydraulic valve.
