REPLACING THE FUEL FILTER

Refer to Table 3 for scheduled replacement of the

fuel filter (Figure 9). A dirty fuel filter may be the

cause if the engine fails to start. The fuel filter is ac-

cessible through the maintenance access door in

the skid-base. Squeeze the latches together to

open the door.

CAUTION

Wipe dirt off the fuel hose connec-

tions at the fuel filter before disconnecting the

hoses so as to keep dirt out of the fuel system.

WARNING

Diesel fuel is combustible and can

cause severe personal injury or death. Do not

smoke. Keep flames, sparks, pilot lights, electri-

cal arcs, switches and arc-producing equip-

ment and all other sources of ignition well away.

Keep a type ABC fire extinguisher handy.

Removing the Fuel Filter: To remove the filter, dis-

connect the two fittings at the filter and remove the

mounting nut. Apply a wrench on the filter fitting as

well as on the flare nut so as not to stress the fitting.

Flare nut wrenches should be used on the flare nuts

so as not to round the corners on the nuts. Dispose

of the fuel filter according to local regulations.

Installing the Fuel Filter: Rotate the filter half a

turn around its mounting stud if the fittings interfere

with the bracket. It only fits properly one way.

Connect the fuel fittings before tightening the filter

mounting nut. Take care not to crossthread the fuel

fittings. Thread them in by hand and tighten one flat

past seating.

Close the access door and prime the fuel system by

holding the control switch down in its Stop position

for at least 1 minute. Priming is necessary to dis-

place the air in the new filter with fuel.
