Servicing the air cleaner
To remove the dust from the evacuator valve squeeze it between thumb and fingers to let excess dust out
and wipe around the valve to keep it clean from outside.
To clean the main element, remove the right fan cover.
Remove dust by blowing it out of the element with Compressed air.
Check the element to ensure it is not damaged. Reassemble the element.
Important:
Never beat the element on a stone or concrete floor/wall to clean it.
Check all connections and hoses especially on the clean side of the air cleaner to ensure no dusty
air can enter the engine. Check the element for flaws by putting a light inside the element.
When reassembling make sure all surfaces seal correctly to keep dust out.
When working in dusty conditions increase the service frequency.
- 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 cause fires.
Damaged radiator hoses can cause hot water burns and in severe cases seize 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 fires to both the tractor and surrounding area so get the dealer to
check it annually. Likewise fuel pipes and wiring age with use.
Ask your dealer to check it at least once every 2 years and replace as required.
