Lubrication Oil
Fill the engine crankcase with lubricating oil through the filler
hole, but do not overfill. Make sure the welder/generator is
level. With the dipstick inserted all the way, but without being
screw into the filler hole, verify that the oil level is maintained
between the two notches (Figure 7) on the dipstick. See
Table 4 for proper selection of engine oil.
Fuel
Fill the fuel tank with clean and fresh unleaded gasoline. DO
NOT fill the tank beyond capacity.
Pay attention to the fuel tank capacity when replenishing
fuel. Refer to the fuel tank capacity listed on page 11,
Specification Table 1.
The fuel tank cap must be closed tightly after filling. Handle
fuel in a safety container. If the container does not have a
spout, use a funnel.
CAUTION :
Never fill the fuel tank while the engine is
running or in the dark. Gasoline spillage
on a hot engine can cause a fire or
explosion. If gasoline spillage occurs, wipe
up the spilled gasoline completely to
prevent fire hazards.

Air Cleaner
Periodic cleaning/replacement is necessary. Inspect it in
accordance with the engine manual.
Battery
This unit is of negative ground. DO NOT connect in reverse.
Always maintain battery fluid level between the specified
marks. Battery life will be shortened, if the fluid level is not
properly maintained. Add only distilled water when
replenishment is necessary.
The battery is sufficiently charged if the specific gravity of
the battery fluid is 1.28 (at 68° F). If the specific gravity
should fall to 1.245 or lower, it indicates that the battery is
dead and needs to be recharged or replaced.
Check to see whether the battery cables are loose. Poor
contact may result in poor starting or malfunctions, always
keep the terminals firmly tightened. Coating the terminals
with a thin film of grease will help to inhibit corrosion.
The battery gradually deteriorates over time. The actual life
span will vary according to operating conditions, but
generally a battery two years or older should be replaced.
