FUEL FILTER:
WARNING
When working on the fuel system:
• Keep naked lights away.
• Do not smoke !
• Do not spill fuel !
Inspect the fuel filter daily. Replace the fuel filter car- tridge every 1000 hours of operation. Dust and dirt in the fuel system can cause the injection pump and injection nozzle to wear quickly. Replace the fuel filter as follows (See Figure D.1.):
1.Close the fuel stopcock.
2.Loosen the fuel filter cartridge with a removal tool and spin the cartridge off. Catch any escaping fuel in an appropriate container.
3.Clean the sealing surface of the filter carrier. Apply a light film of oil or diesel fuel to the rubber gasket of the new fuel filter cartridge.
4.Screw the new cartridge into position finger tight until the gasket is evenly seated. Then turn it down another 1/2 turn. Do not over tighten the new filter.
5.Open the fuel stopcock. Check the assembly for leaks.
BLEEDING THE FUEL SYSTEM: If the engine is oper- ated until it runs out of fuel, you will need to bleed air from the fuel system in order to start the engine. See the engine operation manual for the recommended procedure.
AIR FILTER
CAUTION
The air filter element is a dry cartridge type. It can be cleaned and reused; however, damaged elements should not be reused. Remove loose dirt from the ele- ment with compressed air or a water hose directed from inside out. Compressed Air: 100 psi maximum with nozzles at least one inch away from element. Water Hose: 40 psi maximum without nozzle.
Soak the element in a mild detergent solution for 15 minutes. Do not soak more than 24 hours. Swish the element around in the solution to help remove dirt. Rinse the element from inside out with a gentle stream of water (less than 40 psi) to remove all suds and dirt. Dry the element before reuse with warm air at less than 160° F (71° C). Do not use a light bulb to dry the ele- ment.
Inspect for holes and tears by looking through the ele- ment toward a bright light. Check for damaged gaskets or dented metal parts. Do not reuse a damaged ele- ment. Protect the element from dust and damage dur- ing drying and storage.
Replace the air filter after six cleanings. A cleaned fil- ter will have approximately 70% of the life of a new fil- ter element. A restricted filter element may not appear excessively dirty.
COOLING SYSTEM: The Deutz diesel engine is air cooled. Clean the engine cooling system periodically to prevent clogging the air passages on the cylinder heads and oil cooler, which would overheat the engine. Consult the engine operation manual. It is important to locate the welder to provide an unrestricted flow of clean, cool air.

Excessive air filter restriction will result in reduced engine life.
1.Service air cleaner regularly according to engine operation manual.
2.Stop engine after 100 hours of running time and clean filter element, replace the filter if necessary.
The air filter canister is located behind the engine door on top of the air intake box.
