dipstick and oil fill cap to facilitate complete draining
process. When oil is drained, replace dip stick, oil fill
cap, oil hose drain cap and place hose in holding clip.
OIL FILL:
Replace oil with premium grade API
SJ/10W-30 oil when ambient temperature is above 32º
F (0º C). When temperature is below 32º F, use a syn-
thetic premium grade, API SJ/CF5W-30W. This syn-
thetic oil facilitates cold weather starting. Oil level
should reach “upper limit” level on oil dipstick.
CAUTION:
Too much oil can cause oil foaming, high
oil consumption (white smoke emitting from exhaust)
or high operating temperature. Also, too little oil (oil
level to, or below “lower limit” on oil dipstick) can
cause severe engine damage.
For best starting results, oil should be scheduled to
change, using synthetic oil, just before winter season,
in those cold climate areas. After oil is changed, re-
place dipstick and oil fill cap.
SPARK PLUG:
Remove the plug and inspect it’s con-
dition. Also, clean the plug threaded base and tem-
porarily cover, to keep dirt and debris from falling
into plug hole. Replace the plug if it is badly worn or
in questionable condition.
CAUTION: WHEN RE-
PLACING SPARK PLUGS, ALWAYS CHECK THE
SPARK PLUG GAP AND RE-GAP PLUG FOR DRY
FUEL USE, IF REQUIRED.
Clean good plugs with a
wire brush. Do not sand blast or air blast the plug
electrode. Re-gap existing or new plug to
0.30 - 0.40 mm (0.012 - 0.016 in) for Honda engines,
0.70 - 0.80 mm (0.028 - 0.032 in) for Vanguard & Su-
baru engines, by using feeler gauge and bending
plug electrode. Replace spark plug at recommended
torque values.

COOLING SYSTEM:
Engines may be air cooled or
liquid cooled with a radiator. Inspect the debris
guard on engine air intake to insure no obstructions
have accumulated. Inspect radiator (liquid cooled
sets) to insure no debris accumulation has occurred.
Some generator models have bug/rodent screens.
Inspect and clean off any aluminum screens that may
collect debris.
EXHAUST SYSTEM:
One end of generator set, will
be the hot exhaust discharge. Keep any combustibles
(building materials, fuels, chemicals, flammables,
etc.) away from this exhaust area. Periodically in-
spect exhaust system components (flexible pipes,
mufflers, clamps, etc.) for leaks, cracks, or corrosion.
Your muffler maybe equipped with a spark arrestor
screen, which prevents exhaust sparks from exiting
the exhaust system. This screen must be checked and
cleaned, every 50-75 hours of engine operation.
NOTE:
Check run time meter for periods of mainte-
nance.
CORROSION:
Depending on the area of generator
installation, will depend on the amount of attention
given to cleanliness. Heavy concentration of salt wa-
ter exposure will require frequent washings and a
final waxing of housing exterior. Salt water corrosion
may enter the interior of generator housing, which
must be removed by special detergents. Every 3
months, spray the engine governor linkage and other
engine moving parts, and engine, generator, base
exterior with a light coverage of WD-40 to prevent
corrosion build-up, on these parts.
Only professional generator repair person should
clean and/or spray oil inside the generator housing.
BATTERY:
Inspection should include:
●
Inspect battery posts and cables for corrosion
build-up. Clean and tighten as required.
●
Have the state of charge and over all condition
checked. A fully charged battery should test at 12.5-
13.0 volts D.C.
●
See battery section on page 17 for further informa-
tion.
After each maintenance repair procedure is com-
plete, remember to replace 10 amp controller fuse,
and set controller switch to “STANDBY” position.
