(3) Checking the governor lever and accelerating device .
The governor lever and accelerating devices (accelerating lever, pedal.
etc.) of the machine unit are connected by a fixed linkage to a
pneumatic actuator. If the linkage becomes loose, the deviation in the
position may result and make operation unsafe. Check the linkage
connections for excess play. For adjustment of linkage see
compressor operation section.
Governor Control Seals
As the governor is precisely adjusted, most of the controls are sealed,
please do not break them. Should any adjustment be necessary,
contact your local Ingersoll--Rand branch or distributor.
NOTE: Ingersoll- Rand will not accept any warranty claim on an
engine with broken governor seals.
(4) Replacing fuel filter
Replace the fuel filter at specified intervals before it is clogged with dust
to adversely affect the fuel flow. Also, replace the fuel filter after the
engine has fully been cooled.
1) Remove the fuel filter using a filter wrench(customer procured).
When removing the fuel filter, hold the bottom of the fuel filter with a
piece of rag to prevent the fuel oil from dropping. If you spill fuel, wipe
such spillage carefully.
2) Clean the filter mounting surface and slightly apply fuel oil to the
gasket of the new fuel filter.
3) Install the: new fuel filter manually turning until it comes into contact
with the mounting surface, and tighten it further to 1/2 at a turn, using
a filter wrench. Tightening torque: 11.8

4) Bleed the fuel system. Refer to section 2 of inspection at 50 hours
IMPORTANT:
Be sure to use genuine IR part (super fine mesh filter). Otherwise, it
results in engine damage, uneven engine performance and shorter
engine life.
(5) Changing oil/water separator element.
NOTE :
The cartridge and bowl contain fuel. Take care not to spill it during
disassembly and reassembly.
The fuel filter/separator also provides primary filtration and the element
‘C’ should be changed every 500 operating hours or 6 months,
whichever comes first.
Change procedure:
Unscrew the element ‘C’ from the head taking care not to spill fuel inside
the machine. Drain any fuel within into a suitable container, then
unscrew the clear bowl ‘D’ from the element.
Discard the old element into a suitable container.
Remove the old ‘O’ ring from the bowl ‘D’ and install the new one
supplied with the element. Apply a light coat of clean engine oil to the
‘O’ ring and screw the bowl ‘D’ onto the new element ‘C’.
Using a clean cloth, wipe the sealing face of the filter/separator head
to ensure correct seating of the sealing ring.
Fill the element/bowl assembly with clean fuel oil then apply a light coat
of clean engine oil to the new element seal ring.
Screw the new element onto the head firmly by hand.
Follow the “fuel system air bleeding” procedure. see “inspection after
every 50 hours operation” section 2.
(6) Air cleaner element inspection
AIR INTAKE SYSTEM
Air cleaner
Engine performance and life vary with the air intake conditions.
A dirty air cleaner element reduces the amount of intake air, causing
reduced engine output and possible engine damage.
Also, a damaged element leads to abrasion of cylinders and valves,
resulting in increased oil consumption, reduced output and shortened
engine life.
INSPECT THE CONDITION OF THE ELEMENT.

C Indicator
D Red signal
Air cleaner with dust indicator
This indicator is attached to the air cleaner. When the air cleaner
element is clogged, air intake resistance becomes greater and the dust
indicator signal turns to red indicating the element needs to be
changed.
When the signal turns to red, replace the element. Then press the dust
indicator button to reset the indication.
(1) Checking and adjusting cooling fan V--belt (2nd time and after)
Check and adjust the cooling fan V--belt tension every 250 hours
operation from 2nd time and on.
