FUEL FILTER:
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
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.
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.
