Generac Power Systems 9344-2 - Manual (Page 10)

ADDITIONAL INFORMATION
• Following the initial 25-hour break-in period, avoid light
electrical loads for the next 75 hours of operation. 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 con­
sume 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
responsible for any changes.
Change engine crankcase oil and oil filter.
Check all fluid levels.
Check ail 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 fuel fittings and hoses.
Inspect V-belts for condition and proper tension.
Inspect the exhaust system for damage, deterioration,
leaks proper operation.
Inspect the electrical system.
Inspect the installation for safety violations, compliance
with codes and standards.
FREEZING TEMPERATURE OPERATION
The engine cooling system should have been proper­
ly filled with a 50-50 mixture of low silicate, ethylene
glycol base antifreeze and soft water. When adding
coolant to the radiator or to the coolant recovery bot­
tle, add only the recommended 50-50 mixture. Refer
to SPECIFICATIONS section. If the recommended
50-50 mixture is added to the system consistently, the
unit adequately protect 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 com­
bustible substance. The generator’s exhaust system
becomes extremely hot and can cause fire if it is too
close to combustible materials.
The generator’s exhaust system gives off deadly car­
bon monoxide gas. This dangerous gas, if breathed
in sufficient concentrations can cause unconscious­
ness 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 exhaust outlet and take any other
steps that may be necessary to prevent exhaust
gases from entering rooms or areas occupied by peo­
ple 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 will have an
adverse affect on the insulation resistance of those
windings.
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 insulation resistance and will eventually
cause problems. Dirt will make the problem worse,
since dirt tends to hold moisture
in contact with the
windings. Sait (as from sea air) will also worsen the
problem since it tends to absorb moisture from the air.
Salt and moisture, when combined, form a good elec­
trical conductor.
