Operating the Generator Set
a. Pre-start Inspection
(1)
Always be sure there is sufficient oil and coolant in the engine.
(2)
Be sure the fuel shutoff valve is open. The valve is located at the fuel tank outlet. Observe the
fuel gage. Make certain of sufficient fuel to complete the job to be done.
(3)
If the unit is trailer mounted and is not connected to a tow vehicle, be sure the parking brake is
applied and that the drawbar is raised and locked in the vertical position.
(4)
Open the engine compartment doors and inspect interior for rags, tools, and foreign material.
b. Pre-start Instructions
In all probability, the unit will be moved from one location to another many times during its lifetime of
service. Therefore, the following steps should be taken to optimize maximum efficient operation.
(1)
Check the supply of fuel, crankcase oil and radiator coolant. See the Engine Manufactures
User’s Manual for specifications.
(2)
Inspect the unit thoroughly to be sure it is in proper working order. Check all fuel lines and wire
connections to be certain they are secure. Tighten any loose screws, nuts or bolts.
(3)
Wipe off the entire unit and blowout air passages, control box, and other hard to reach places
with compressed air not over 25 psi (172 kPa).
(4)
Make sure that no loose bars, tools, parts, etc., are in or on any part of the engine, as they could
cause serious damage to the engine, generator, or personal injury to anyone standing nearby.
(5)
If the unit is operated indoors, make sure that an exhaust line is properly connected to the
engine exhaust system, and discharged outside. Avoid short bends or reduction in line sizes in
exhaust pipes. Locate the unit so as to necessitate the shortest possible exhaust line to insure
the least amount of back-pressure on the engine. Back-pressure can cause engine damage and
loss of power.
(6)
Check the electrical system to make sure the connections are secure and properly connected.
(7)
If applicabled, check the battery electrolyte level. The factory installed battery is maintenance
free.
