Inspection Every 50 Hours Operation; Draining Of The Fuel Tank (Not 7/26E, 7/31E); Draining Of The Oil/Water Separator; Inspection Of Battery - Ingersoll-Rand 7/26E Operation And Maintenance Manual

Inspection every 50 hours operation

(1) Draining of the fuel tank (NOT 7/26E, 7/31E)

1) Prepare a waste oil container.
2) Remove the drain plug of the fuel tank to drain (water, dust ,etc.)
from the fuel tank bottom.
fuel
3) Drain until with no water and dust flow out. Then tighten the
drain plug firmly.

(2) Draining of the oil/water separator

Draining Water from Fuel Filter/separator.
The fuel filter/separator is provided to allow water to be drained from the
fuel system. Water is heavier than fuel so any water contained in the
system will collect in the bottom of the bowl.
The clear bowl 'D' should be checked on a daily basis and if water is
present, it should be drained from the separator.
Place a suitable container under the separator to prevent any spillage
inside the machine.
Slacken the drain valve 'E' until water drains from the vent tube.
When all the water has been evacuated, tighten the drain valve 'E' and
follow the "fuel system air bleeding" procedure below.
Fuel System Air Bleeding
The entry of air into the fuel system will cause difficult engine starting
or engine malfunction.
When carrying out service procedures such as emptying the fuel tank,
draining the filter/separator, and changing the fuel filter element be sure
to bleed air from the fuel system.
To activate the "automatic air−bleeding system", turn the key switch to
the "ON" position and energize the electromagnetic pump" to bleed the
air.
Air bleeding method:
When the "starter switch" is set to the "ON" position to activate the
electromagnetic pump, fuel is forced to the fuel valve of each injection
pump and then to the leak−off pipe of each injector nozzle, so that any
air in the fuel system bleeds off automatically to the fuel tank.
NOTE:
Although the fuel system can bleed air automatically when the key
switch is in the "ON" position, air can also be manually bled by use of
the primer pump facility in the filter/separator assembly.
By unscrewing the plastic primer pump head 'A' and stroking it up and
down, any air bubbles in the system will be purged back to the fuel tank.
When this has been completed, the pump head must be screwed back
into the filter/separator assembly.
Start the engine and visually check the fuel system for leaks.
PERIODICAL INSPECTION AND MAINTENANCE
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.

(3) Inspection of battery

Fire due to electric short−circuit
S Make sure to turn off the battery switch or
disconnect the negative cable
inspecting the electrical system. Failure to do so
could cause short−circuiting and fires.
S Always disconnect the
cable first before disconnecting the battery cables
from battery. An accidental "Short circuit" may
cause damage, fire and or personnel injury.
And remember to connect the (−) Negative battery cable (back onto the
battery) LAST.
Proper ventilation of the battery area
Keep the area around the battery Well ventilated,
paying attention to keep away any fire source.
During operation or charging, hydrogen gas is
generated from the battery and can be easily
ignited.
Do not come in contact with battery electrolyte
Pay sufficient attention to avoid your eyes. or skin
from being in contact with the fluid. The battery
electrolyte is dilute sulfuric acid and causes burns.
Wash it off immediately with a large amount of
fresh water if you get any on you.
S Clean the battery terminals
S Check the level of fluid in the battery.
When the amount of fluid nears the lower limit, fill with battery fluid
(available in the market) to the upper limit. If operation continues with
insufficient battery fluid, the battery life is shortened, and the battery
may overheat and explode.
S Battery fluid tends to evaporate more quickly in the summer, and the
fluid level should be checked earlier than the specified times.
