electric light bulb inside the element and looking
through it. If any damage is noted, discard the
element and fit a new one.
Replace the air filter element after 10 cleanings or
once a year, whichever comes first.
When fitting, make sure the element is seated
properly and the sealing is in good condition.

A safety element (4) is fitted as an additional security
to prevent dust from entering the engine when
replacing the standard element.

CAUTION
The safety element should not be cleaned.
Replace the safety element every two years.

o

The seals of the brake slave cylinders contain
fluoroelastomers which, when used under
normal conditions, are perfectly safe.
If however they are exposed to temperatures in
excess of 315° C (599° F), the material will not
burn, but decompose.
An extremely corrosive acid is almost impossible
to remove once it has contaminated the skin.

SECTION 4 - LUBRICATION AND MAINTENANCE
BRAKES

WARNING

The braking system of your combine was carefully
designed and balanced to provide optimum braking
performance.
It is important to ensure that only brake linings
meeting NEW HOLLAND specifications for the
combine are used. The use of brake linings having
incorrect friction properties may result in a reduction
of braking efficiency. Only use genuine NEW
HOLLAND replacement parts.
Brakes belong to the components that are subject to
homologation in many countries, and must therefore
not be altered.

CAUTION
In case of leakage or malfunction of the brake
system, contact immediately your local dealer.

3. The foot brake is correctly adjusted when the
brake cylinder displacement is between 5.8 and
6.2 mm.
Adjust with the nuts 7.
Combines stored for several days or weeks may
require a "bedding-in" procedure before the
machines are put into operation in order to ensure a
consistent brake performance.
Foot brake "bedding-in" procedure
1. Drive the machine at minimum throttle in first or
in second gear.
2. Apply the brakes without declutching or bringing
the hydrostatic control lever to neutral position
(i.e. brake against the engine power).
Press down the brake pedals as hard as you can
(approximately 80 kg force) for about 5 seconds,
then release the brakes.
3. Repeat this procedure twice or three times.
