OPERATION

RANGER 8+ DIESEL

BREAK-IN PERIOD

Any engine will use a small amount of oil during its
“break-in” period. For the diesel engine on the
RANGER 8+ DIESEL, break-in is about 50 running
hours.

Check the oil every four hours during break-in.
Change the oil after the first 20 hours of operation,
then at 100 hours of operation, then every 200 hours
thereafter. Change the oil filter at every second oil
change.

During break-in, subject the RANGER 8+ DIESEL to
moderate loads. Avoid long periods running at idle.
Before stopping the engine, remove all loads and
allow the engine to cool several minutes. Care should
be taken that the engine is not run at very light loads
for extended periods as this can lead to glazing of the
cylinder bores. On the other hand, it is wise not to
exceed 70% of the maximum output of the engine for
the same period while bearing surfaces are bedding
in. Cylinder glazing can lead to excessive oil con-
sumption and smoky exhaust, while overloading of the
engine during the first few hours can lead to excessive
wear and shorten the life of the engine.

WELDING OPERATION

The RANGER 8+ DIESEL machines can deliver from
40 to 250 amps of constant current for AC stick weld-
ing and 40 to 225 amps of constant current DC stick
welding. The RANGER 8+ DIESEL can deliver 40 to
200 amps of constant voltage current for DC semiau-
tomatic wire feed welding. AC/DC constant current
TIG welding is possible across the entire range from
40 to 250 amps. 250 amps is the maximum recom-
mended for AC TIG welding of aluminum.

Output can be adjusted by setting the POLARITY
SWITCH, the OUTPUT RANGE dial, and the FINE
CONTROL dial on the output control panel to the set-
tings that are best for your selected welding process.

Do not attempt to use this equipment until you
have thoroughly read the engine manufacturer’s
manual supplied with your welder. It includes
important safety precautions, detailed engine
starting, operating and maintenance instructions,
and parts lists.
