1. Activate hydraulic control lever
2. Raise boom until it is clear of the transport brackets.
3. Turn blower on to prevent boom hydraulics by-passing
through the blower.
4. Activate double-acting hydraulic control lever to unfold
the boom.
5. When boom wings are completely unfolded, activate
lever to unlock trapeze.
6. Lower boom to desired working height.

The angle of the air stream can
be altered from 18° forward to
18° backward. Unfold the
boom. The angle of the air
stream outlet is automati-
cally set backward 18° by a
small ram under the centre
section.
The angle can be
altered via the
electric remote. If
the electric
power should
fail, it is possible
to manually change the angle by pushing the buttons on
the solenoid valve on the blower.

Unfold the boom and lock the tractor double activating
hydraulic lever to open position and increase engine
revolutions to correspond with forward speed.
To increase or decrease the fan revolutions and thereby
air volume, adjust valve
B
on the hydraulic block.
CAUTION!
For the safety of the operator, no
other persons may carry out adjustments.
After the oil has driven the hydraulic motor, it then
passes through a cooler before returning to the tractor.
This ensures the hydraulic oil does not overheat.
NOTE!
For maximum performance from the
blower, the tractor hydraulic system must meet
the following demands.

WARNING!
Before unfolding the boom it is
important to connect the sprayer to the tractor to
prevent overbalancing of the sprayer.
WARNING!
Testing of the hydraulic system
should be done very cautiously. There may be air
in the system and this may cause violent move-
ments of the boom. Therefore take care that no persons
or objects are hurt or damaged in the process of testing.
DANGER!
When folding or unfolding the boom,
make sure that no persons or objects are in the
operating area of the boom.
DANGER!
Always follow the guidelines listed
below when driving in areas with overhead power
lines:
Never use the folding/unfolding functions in areas
with overhead power lines.
Unintended boom movements can cause contact
with overhead power lines.
NOTE!
A label (ref. no. 978448) follows the sprayer. This
label must be placed in the cabin at a place visible from
the operator’s seat.

Following operations are carried out by the tractor’s
hydraulic control lever(s)
•
Raising/lowering of the boom
•
Folding/unfolding the boom
•
Slanting control (optional
equipment)
Speed regulation of the hydrau-
lic movements can be altered.
A restrictor valve is located at
the hydraulic block on the
blower. It must be adjusted
so the boom operates smoothly.
Nut
A
is loosened, and the distance “
x
” is
adjusted. Reducing the distance reduces
the speed of the boom movements.
NOTE!
If the boom has difficulty in
unfolding, increase the oil flow to the
blower by turning valve
B
on the blower.
