SECTION 4 - LUBRICATION AND MAINTENANCE

Condenser

Regularly inspect and clean the condenser 1 with

compressed air.

To gain access to clean the condenser: refer to

”Rotary dust screen and cooling system” in this

section.

220

Fresh air intake grill

The fresh air intake grill is located behind the

left-hand front shield.

To clean the dust on the fresh air intake grill, open

door 1 on the fresh air intake box by turning the latch

221

Recirculation filter

The recirculation filter 2 is located in the cab, on the

right-hand side of the operator ’s seat.

Clean the cab air filter regularly and, in extremely

dusty conditions, daily.

To clean remove the recirculation grill.

NOTE: To easily remove, push up the grill and rotate

it out of the opening.

222

SECTION 4 - LUBRICATION AND MAINTENANCE

Filter-drier

The filter-drier is located on the right hand side of the

engine cover.

Remove cover 1 (if installed) to view the filter-drier.

223

A sight glass 2 and a ring-shaped moisture indicator

1 serve for determining the condition of the R 134a

gas.

• If the refrigerant is without air bubbles, then the

refrigerant condition is good.

• If the glass shows a milky refrigerant: good

condition in ambient temperature.

• If air bubbles are visible: lack of refrigerant.

• If the moisture indicator is blue: filter and

refrigerant are in good condition.

• If the moisture indicator is red: this is an indication

224

of too much moisture, the filter-drier has to be

replaced.

• If the moisture indicator is brown or black: too

much contamination: filter-drier has to be

replaced.

NOTE: The filter-drier must always be replaced when

the air circuit has been opened.

If the filter-drier needs to be replaced, or if the air

conditioning system needs repair, contact your local

dealer.

SECTION 4 - LUBRICATION AND MAINTENANCE

AIR COMPRESSOR (IF INSTALLED)

• CNH engine:

The air compressor 1 is installed near the engine and

needs no further maintenance.

225

• Iveco engine:

The air compressor 1 is installed onto the engine and

needs no further maintenance.

226

Every 50 operating hours, drain the condensated

water from the air reservoir through cock 2.

Two unions 3 are installed to attach pneumatic ser-

vice tools and for cleaning purposes.

The inner thread of the union is 1/2 GAZ CYL.

One is located under the air reservoir.

227

SECTION 4 - LUBRICATION AND MAINTENANCE

A second is located at the top of the straw hood near

the oil reservoir.

228

Air reservoir specification

(according to European Directive 87/404/EEC)

• Trade mark: Wabco

• Type: ”60 l”

• Maximum operating pressure: 10 bar

(145.1 PSI)

• Maximum operating temperature: +100_ C

(212_ F)

229

• Minimum operating temperature: - 50_ C

(-58_ F)

• Capacity: 60 litres (15.85 US gal)

• Approval date: see cold stamping on the air

reservoir.

IMPORTANT: For France, the air reservoir must be

reapproved (technical control) every 5 years.

The owner has to take the necessary actions to have

the reservoir retested before the expiry date which is

the approval date + 5 years.

SECTION 5 - FAULT FINDING

Manual release of the hydraulic parking brake

If it is not possible to release the handbrake

electrically, it can be released manually.

To release the handbrake manually, proceed as

follows:

1. Park the combine level.

2. Raise the header and engage the header safety

latch. Stop the engine.

3. Block the wheels adequately to prevent the

combine from running.

4. Remove rubber cap 1.

5. Remove cotter pin 2 and screw on nut 3 until the

handbrake piston is completely pulled backward

to release the pressure on the brake disc.

DANGER

Be aware that the emergency brake does not operate

when the brake is manually disengaged. Repair as

soon as possible to restore correct operation. In the

meantime, use wheel edges to prevent the combine

from running away whenever parked.

SECTION 5 - FAULT FINDING

Gearshifting

If not possible to select gears electronically (gearshift

latch. Stop the engine.

3. Block the wheels adequately to prevent the

combine from running.

4. Loosen the bolts to remove traction gearbox

5. Loosen four bolts 1 and remove the electric

motor.
