Cautions for inspection and service of air cleaner
(1) Use the specified filter replacement parts.
(2) Thoroughly remove dust from the cover.
(3) Mount it firmly so that dust cannot enter under the cover.
(4) Never drive with the element and the fine filter removed.
(5) Replace the air cleaner filter and filter element according to their replacement plan or when the indicator
light comes on, whichever comes first.
Note:

Do not shake the element to clean it, use compressed air. Blow the filter element upstream of the
engine. Be careful not to tear the filter element by air pressure.

Make sure to install the element firmly.

Tighten all parts of the air filter thoroughly to prevent dust and dirt from entering.
Replace the element after cleaning it 5 times or it is damaged.
Checking Hoses and Lines
The fuel lines, radiator hoses, hydraulic and rubber hoses are consumables, which deteriorate by age and
use. Check them regularly and replace if faulty.
CAUTION:

Damaged fuel lines leak and may cause fire.

Damaged radiator hoses can cause hot water burns and, in severe cases, damage the engine.
Checking the Wiring Harness and Fuses
Loose wires make inferior connections and damaged wires can cause short circuits, fires burnt wiring or
reduce efficiency of components.
Replace or repair any faulty wiring or insulation.
If a fuse burns out again after it has been replaced, do not replace it with wire or a high capacity fuse, find
the cause and rectify it or get an auto electrician to do so.
Where insulation is chafed or peeled off, recover the area with a good quality insulation tape. Where wiring
comes out of it's fitting replace it correctly with the standard fitting.
IMPORTANT

Incorrect wiring or fuses can cause fire to both the tractor and the surrounding area, so have it
checked annually by an authorized service.

Proceed similarly for fuel lines.

Ask an authorized service center to check them at least every 2 years and replace as
necessary.
