Operating Instructions
If the unit is equipped with a fuel valve, it must be opened.
To ensure prompt starting, fill the fuel system between the pump and the fuel return manifold with fuel. If the engine has
been out of service for a considerable length of time, prime the filter between the fuel pump and the injectors. The filter
may be primed by removing the plug in the top of the filter cover and slowly filling the filter with fuel.
In addition to the above, on an engine equipped with a hydrostarter, use a priming pump to make sure the fuel lines and
the injectors are full of fuel before attempting to start the engine.
NOTE: The fuel system is filled with fuel before leaving the factory. If the fuel is still in the system when
preparing to start the engine, priming should be unnecessary.
Lubrication Fittings
Fill all grease cups and lubricate at all fittings with an all purpose grease. Apply lubricating oil to the throttle linkage and
other moving parts and fill the hinged cap oilers with a hand oiler.
Drive Belts
Adjust all drive belts as recommended under Lubrication and Preventive Maintenance.
Storage Battery
Check the battery. The top should be clean and dry, the terminals tight and protected with a coat of petroleum jelly and
the electrolyte must be at the proper level.
NOTE: When necessary, check the battery with a hydrometer; the reading should be 1.265 or higher.
However, hydrometer readings should always be corrected for the temperature of the electrolyte.
Generator Set
Where applicable, fill the generator end bearing housing with the same lubricating oil as used in the engine.
A generator set should be connected and grounded in accordance with the applicable local electrical codes.
CAUTION: The base of a generator set must be grounded.
Clutch
Disengage the clutch, if the unit is so equipped.
STARTING
Before starting the engine for the first time, perform the operations listed under Preparation For Starting Engine First
Time.
Before a routine start, see Daily Operations in the Lubrication and Preventive Maintenance Chart.
If a manual or an automatic shutdown system is incorporated in the unit, the control must be set in the open position
before starting the engine.
The blower will be seriously damaged if operated with the air shut-off valve in the closed position.
Starting at air temperatures below 40F (4C) requires the use of a cold weather starting aid. See Cold Weather Starting.
The instructions for the use of a cold weather fluid starting aid will vary dependent on the type being used. Reference
should be made to these instructions before attempting a cold weather start.
WARNING: Starting fluid used in capsules is highly inflammable, toxic and possesses anesthetic properties.
Initial Engine Start (Electric)
Start an engine equipped with' an electric starting motor as follows: Set the speed control lever at part throttle, then bring
it back to the desired no-load speed. In addition, on mechanical governors, make sure the stop lever on the governor
cover is in the run position. Then press the starting motor switch firmly. If the engine fails to start within 30 seconds,
release the starting switch and allow the starting motor to cool a few minutes before trying again. If the engine fails to
start after four attempts, an inspection should be made to determine the cause.
CAUTION: To prevent serious damage to the starter, if the engine does not start, do not press the starting
switch again while the starting motor is running.
