[9] REPLACING THE MAIN FUEL FILTER CARTRIDGE
•
Various parts are at elevated temperatures immediately after stopping the engine
operation. Do not proceed with fuel filter replacement immediately but wait for the
engine to cool to the extent that you can touch it with your hand.
•
In the engine fuel piping, an internal pressure is generated during engine operation.
Before replacing the filter, wait for 30 seconds or more after stopping the engine to
allow the internal pressure to drop, and then replace the filter.
• Be extremely careful of fire such as cigarettes when replacing the fuel filter elements.
CAUTION
•
The genuine fuel filter cartridge employs a special filter having a high-efficiency
filtering characteristic. Always use Maeda genuine filters for the replacement.
•
The common rail type fuel injection system employed in the Machine consists of parts
that have higher precision than that of conventional injection pumps and nozzles.
Substituting the fuel filter cartridge with any products other than the genuine product
may give rise to inclusion of foreign matters and failures in the fuel system. Never use
any substitutes.
•
When conducting the inspection and maintenance services of the fuel system, pay
more attention to the inclusion of foreign matters than that paid for conventional
products, and if rubber or other objects are deposited, use the fuel to thoroughly clean
it.
• Prepare a container to receive spent oil.
• Have a filter wrench available. (Optional product: Part No. 585-3554500)
1. Open the right cover of the machine body.
2. Set the oil receiving container under the fuel filter
cartridge.
3. Loosen the drain plug (1) and air-venting plug (2) to
thoroughly drain the fuel in the filter.
4. By using the filter wrench, turn filter cartridge (3)
counterclockwise to remove it.
5. Replace the filter case (3) and O-ring (4) of drain plug
(1) with new ones, put the new element (5) in the filter
case (3), thinly apply fuel on the O-ring (4), and screw
it in.
6. After allowing the O-ring (6) to come into contact with
the sealing face, tighten the setup by using the
dedicated filter wrench.
CAUTION
•
If any foreign matter or dirt is found on the bottom of
the filter case, clean it.
•
Reusing the element will invite trouble. Never fail to
replace it with a new one.
7. After replacing the filter cartridge, vent the air.
