10.3.2 Drift reduction measures

•

Reschedule treatment for the early morning or the evening hours

(there is generally less wind).

•

Choose larger nozzles and a higher water spray rate.

•

Reduce spray pressure.

•

Precisely maintain the working height of the boom, because the

risk of drifting rises very sharply as the distance between the

nozzles increases.

•

Reduce operational speed (to below 8 km/h).

•

Use so-called anti-drift (AD) nozzles or injector (ID) nozzles

(nozzles which produce a high proportion of coarse drops).

•

Observe the distance requirements of the respective crop pro-

tection agent.

Double Trail

In the following situations, the steering program button starts flashing:

•

The axles are not located correctly for the steering program

selected.

•

At least one axle has reached its end stop and cannot be moved

any further.

The driver has to watch out because the steering behaviour may

change from now on and steering behaviour may be greatly dis-

torted.

•

The vehicle speed has exceeded the warning threshold for field

mode.

The vehicle is moving in the borderline region to the maximum

vehicle speed permitted in field mode.

Field mode can be switched on only when the following conditions

are met:

•

The machine is at a standstill.

•

The speed signals are fault-free.

•

There is no severe fault.

•

The operating sequence has been carried out correctly.

The field mode is switched off by:

•

actuating the road button.

•

automatic switch off when the permissible travelling speed is

exceeded.

•

the steering system is switched on and off.

Switching between the steering programs

Within the field mode, up to a slow travelling speed, you can switch

between steering programs.

When switching over whilst travelling, the axle system is synchro-

nised automatically.

11.3.2 Steering program - track following steering system

1.

direction of the tractor in the direction of travel.

For the driver, this function appears as a direct control of the steered

axles as he has specified.

WARNING

Danger of accident caused by simultaneous and counter-acting

dependency of ramp angle and manual offset on the steering

angle.

The offset should be used with the greatest of care.

11.4

Axle synchronisation

When the operating condition of the steering system is changed, it is

possible that the steered axles may not be in the geometrically cor-

rect position. The initial steering of the axles to reach the correct posi-

tion is referred to as axle synchronisation.

Examples of changes in operating conditions:

ο switching the steering system on and off.

ο changing the steering program.

A lower travelling speed is required to carry out the synchronisation of

the axles.

Cleaning, maintenance and repair

Checking the brake drum for dirt

1. Unscrew the two cover plates (Fig. 140/1)

on the inside of the brake drum.

2. Remove any dirt and plant debris which

may have entered the drum.

3. Refit the cover plates.

CAUTION

Dirt entering the drums may be

deposited on the brake pads (Fig.

140/2) and thus die appreciably

reduce brake performance.

Risk of accident.

If dirt is discovered in the brake drum,

the brake pads must be inspected by

a specialist workshop.

For this to happen, the wheel and

brake drum must be removed.

Fig. 136

Checking the play on wheel hub bearings

To check the play on wheel hub bearings, raise

the axle until the wheels turn freely. Release the

brake. Place a lever between the tyre and the

ground and check the play.

If bearing play can be detected:

Adjust the bearing play

•

Remove the dust cup or hub cap.

•

Remove the split pin from the axle nut.

•

Tighten the wheel nut while turning the

wheel at the same time until the wheel hub

is lightly braked as it turns.

•

Turn axle nut back to the next available split

Fig. 137

pin hole. To the next matching hole (max.

30°).

•

Fit split pin and bend slightly open.

•

Top up the dust cap with high melting point

grease and drive it into, or screw it onto the

wheel hub.

Cleaning, maintenance and repair

Brake pad check

Open the inspection hole (Fig. 143/1) by pulling

out the rubber stopper (if present).

At a residual thickness

a:

for riveted pads

5 mm

(N 2504)

3 mm

b:

for adhesive pads

2 mm

the brake pad must be replaced.

Reinsert the rubber tab.

Brake adjustment

Depending on use, the wear and function of the

brakes must be constantly checked and, if nec-

Fig. 139

essary, readjustment must be carried out. Read-

justment is required after using approx. 2/3 of the

max. cylinder stroke for emergency braking. To

do this, jack up the axle and secure it against

unintended movement.

Adjusting the linkage adjuster

Move the linkage adjuster by hand in the pres-

sure direction. If the free travel of the long-stroke

diaphragm cylinder pressure rod is max. 35 mm,

the wheel brake must be readjusted.

Adjustments are made using the readjustment

hexagon bolt on the linkage adjuster. Set the free

travel "a" to 10-12 % of the connected brake

lever length "B",

e.g. lever length 150 mm = free travel 15 - 18

mm.

Fig. 140

Adjusting the automatic linkage adjuster

Basic settings are made in the same way as for the standard linkage

adjuster. Readjustment occurs automatically at a cam rotation of ap-

prox. 15°.

The ideal lever position (which cannot be altered owing to the attach-

ment of the cylinder) is approx. 15° before perpendicularity, and the

same in the actuation direction.

199

Cleaning, maintenance and repair

Checking the function of the automatic linkage adjuster

1. Remove the rubber stopper cap.

2. Slacken the adjusting screw (arrow) with a

ring spanner approx. ¾ of a turn anti-

clockwise. There must be a free travel of at

least 50 mm for a lever length of 150 mm.

3. Actuate the brake lever several times by

hand. This should cause a smooth automat-

ic readjustment; it should be possible to

hear the coupling engaging and, on the

back stroke, the adjusting screw should turn

clockwise slightly.

4. Refit the stopper cap.

5. Lubricate with BPW ECO_Li91 special high

Fig. 141

melting point grease.

Air reservoir

Drain the air reservoir every day.

(1) Air reservoir

(2) Drainage valve

(3) Test connection for pressure gauge

1. Pull the drain valve in a sideways direction

using the ring until no more water escapes

from the air reservoir.

→ Water flows out of the drain valve.

2. Unscrew the drain valve from the air reser-

voir and clean the reservoir if there are

signs of dirt.

13.5.1 Hydraulic brakes

Check of the hydraulic brake

•

Check all brake hoses for wear

•

check all screw unions for seal tightness

•

renew any worn or damaged parts.

Venting the brake system (workshop work)

After each brake repair, for which the system has

been opened, bleed the brake system, because

air may have entered the pressure hoses.

1. Slightly loosen the vent valve.

2. Actuate the tractor brake.

3. Close the vent valve as soon as oil es-

capes.

→ Collect the escaping oil.

4. Perform a brake check.
