Generac Power Systems 9344-1 - Manual (Page 10)

Following the initial 25-hour break-in period, avoid
light electrical loads for the next 75 hours of opera­
tion. The unit should be loaded at 50% (or more) of
its capacity during those 75 hours. Repeated light
loads during break-in period may improperly seat
the piston rings, resulting in blowby and high oil
consumption.
Check oil level frequently during the break-in period.
Add oil if needed. It is natural for the generator
engine to consume much oil until the piston rings
have seated properly.
When the 25-hour break-in period is done, complete
the tasks recommended under 25-HOUR CHECK­
UP PERIOD.
25-HOUR CHECK-UP PERIOD
After the first 25 hours of operation have been com­
pleted, contact an Authorized Service Facility for the
following maintenance. The Owner/Operator is respon­
sible for any changes.
Change engine crankcase oil and oil filter.
Check all fluid levels.
Check all cooling system hoses and fittings for
damage, deterioration, looseness, etc. Check all
hose clamps for tightness and security.
Check engine for proper operation.
Inspect the diesel engine fuel system for leaks,
tightness and security of fuei fittings and hoses.
Inspect drive belts for condition and proper tension.
Inspect the exhaust system for damage, deteriora­
tion, leaks, proper operation.
Inspect the electrical system.
Inspect the installation for safety violations, compli­
ance with codes and standards.
FREEZING TEMPERATURE OPERATION
The engine cooling system should have been properly
filled with a 50-50 mixture of ethylene glycol base anti­
freeze and soft water. When adding coolant to the
radiator or to the coolant recovery bottle, add only the
recommended 50-50 mixture. Refer to SPECIFICA­
TIONS section. If the recommended 50-50 mixture is
added to the system consistently, the unit adequately
protects against freezing temperatures.
ATTENTION REQUIRED AFTER
SUBMERSION
If the generator has been submerged in water, it must
NOT be started and operated. Following any submer­
sion in water, have an authorized Generac Service
Facility thoroughly clean and dry the generator.
OPERATING PRECAUTIONS
Never operate the generator set while the vehicle is
parked over dry leaves, dry grass or any other combus­
tible substance. The generator’s exhaust sytem be­
comes extremely hot and can cause fire if it is too close
to combustible materials.
The generator’s exhaust system gives off DEADLY
carbon monoxide gas. This dangerous gas, if breathed
in sufficient concentrations can cause unconsciousness
and even death. Never operate the generator set with
the vehicle inside any garage or other enclosed area.
Never operate the generator with a leaking exhaust
system. Close windows in the vicinity of the generator
exhuast outlet and take any other steps that may be
necessary to prevent exhaust gases from entering
rooms or areas occupied by people or animals.
EFFECTS OF MOISTURE AND DIRT
Keep the generator set as clean and dry as possible.
Protect the unit against excessive dust, dirt, corrosive
vapors, road splash, etc. Permitting dirt and moisture
to accumulate on generator windings wii! have an ad­
verse affect on the insulation resistance of those wind­
ings.
When moisture is allowed to remain in contact with
windings, some of that moisture will be retained in voids
and cracks in the insulation. This causes a reduced
insuiation resistance and will eventually cause prob­
lems. Dirt will make the problem worse, since dirt tends
to hold moisture in contact with the windings. Salt (as
from sea air) will also worsen the problem since it tends
to absorb moisture from the air. Salt and moistsure,
when combined, form a good electrical conductor.
