(Bowden cable adjusted pumps only). The boom fan
speed base adjustments are carried out as follows.

A tachometer is required for this job.

1. Fit a piece of light-reflecting tape to the fan wing and

to the tractor P.T.O.

2. Unfold the boom to working position.
3. Set tractor P.T.O. at 540 r.p.m. - check with the

tachometer.

4. Set the fan speed control lever to max. speed.
5. Measure the fan speed with the tachometer. The fan

speed must be 3100 r.p.m.

WARNING!

Do not wear loose hanging clothes!

Hold the tachometer firmly in your hands in order
not to be sucked into the fan. DO NOT REMOVE

THE PROTECTION GRID!

6. Turn the swash plate adjustment screw

E

CW to

decrease or CCW
to increase the
blower r.p.m..
Remember to
tighten the counter
nut. Repeat 3. and
4. until the correct
setting is obtained.

7. If the correct fan

r.p.m. cannot be
reached, the hy-
draulic transmission pressure settings must be
checked - see section on “Fan transmission pressure
adjustment”.

If the hydraulic fan transmission has been dismantled, or
pump or motor has been changed, the following priming
procedure must be carried out before starting up the
transmission:

1. Fill the oil reservoir with

fresh, clean oil to the
top of the sight glass.

2. Fill the pump housing

with oil through the
drain pipe

D

which is

dismantled at the tank
connection. Reconnect
and tighten.

3. Check the oil level in

the gear box.

4. Remove the drain hose

D

from the motor outsidethe

blower housing.

5. Set the fan r.p.m. at 0, engage the tractor P.T.O. with

the engine running idle - wait a few minutes.

6. Set the fan speed at 200 r.p.m.
7. After a while the oil will start dripping constantly. Refit

the drain hose and tighten.

8. With the tractor P.T.O. at 540 r.p.m. the fan should

rotate at max. revolutions/min.

9.Recheck oil level at tank sight glass.
10.Check vacummeter at the suction filter.
11.Retighten hose connections and check for leaks.
12.Check fan speed and feed pressure adjustments -

see sections on “Fan speed adjustment” and “Fan
transmission pressure adjustment”.

The transmission feed and working pressure are
checked as follows:

1. Connect a 40 bar (580 p.s.i.) pressure gauge to the

feed pressure connector

P2,

and a 400 bar (5800

p.s.i.) pressure gauge at the working pressure con-
nector

.

2. Set the tractor P.T.O. at 540 r.p.m. - check with

tachometer.
