CLEANING WATER SEPARATOR
WARNING: FIRE AND EXPLOSION HAZARD
Diesel fuel is flammable and explosive under certain
conditions.
Do NOT perform while the engine is running.
1. Position an approved container under the cup (1) of
the water separator to collect the contaminants.

3. Loosen the drain valve (4) and drain the contaminants.
4. Turn the cup (1) to the left (10), remove the cup (1).
5. Carefully hold the cup to prevent fuel from spilling. If
you spill any fuel, clean up the spill completely.
ADJUSTING THE GOVERNOR
Never attempt to adjust the low or high idle speed limit
screw. This may impair the safety and performance of the
machine and shorten its life. If adjustment is ever required,
contact your Isuzu Distributor.
1. Check that the governor lever (1) makes firm contact
with the high idle stop (2) and the low idle speed limit
screw (3) when the engine speed control is in the full
speed or low idle speed positions.
2. If the governor lever does not make proper contact
with the high idle stop or the low idle speed limit
screw, adjust the throttle cable or linkage as necessary.
4. Replace the element with a new one if the element is
damaged, excessively dirty or oily.
5. Clean inside of the air cleaner cover.
6. Reinstall the element into the air cleaner case (4).
Note: If there is a red line (2) in the outer element, reinsert
the element until the overlap position of red line and end
face of the air cleaner case.
8. Reinstall the air cleaner cover making sure you match
the arrow (5) on the cover with the arrow on the case
(6).
9. Latch the air cleaner cover to the case.
DRAINING WATER SEPARATOR
WARNING: FIRE AND EXPLOSION HAZARD
Diesel fuel is flammable and explosive under certain
conditions.
Drain the water separator whenever there are
contaminants, such as water, collected in the bottom of the
cup. Never wait until the scheduled periodic maintenance if
contaminants are discovered.
The separator cup is made from semi-transparent material.
In the cup is a red-colored float ring. The float ring will rise
to the surface of the water to show how much needs to be
drained.
1. Position an approved container under the water
separator (1) to collect the contaminants.
2. Close (2) the fuel valve (3).
3. Turn the retaining ring (4) to the left (9).
4. Carefully remove the cup (1). Remove the retaining
spring (6) and float (7) from the cup. Pour the fuel into
an approved container and dispose of waste properly.
Hold the bottom of the cup with a shop towel
to prevent the fuel from dripping. Wipe up any spills
immediately.
5. Clean the inside of the cup.
6. Inspect the condition of the mesh filter (10). Clean the
mesh filter if necessary.
7. Inspect the condition of the O-ring (11). Replace the
O-ring if necessary.
8. Put the float (7) and retaining spring (6) inside the cup.
9. Reinstall the cup to the mounting flange (8) and turn
the retaining ring (4) to the right (5). hand-tighten only.
