OIL

The RANGER 250 is shipped with the engine crankcase filled with
high quality SAE 10W-30 oil. Check the oil level before starting the
engine. If it is not up to the full mark on the dip stick, add oil as
required. Check the oil level every four hours of running time during
the first 25 running hours. Refer to the engine Operator's Manual for
specific oil recommendations and break-in information. The oil
change interval is dependent on the quality of the oil and the operat-
ing environment. Refer to the Engine Operator's Manual for the
proper service and maintenance intervals.
INSTALLATION

FUEL

(1)
USE GASOLINE FUEL ONLY
Fill the fuel tank with clean, fresh fuel. The capaci-
ty of the fuel tank is 12 gallons (45.4 liters). When
the fuel gauge reads empty the tank contains
approximately 2 gallons (7.6 liters) of reserve fuel.
NOTE: The fuel tank is mounted below the engine
so a fuel shutoff valve is not required.
-----------------------------------------------------------------------
ENGINE COOLING SYSTEM
Air to cool the engine is drawn in lower set of louvers
on the case back. It is important that the intake air is
not restricted. Allow a minimum clearance of 2 feet
(0.6m) from the case back to a vertical surface.
BATTERY CONNECTION
Use caution as the electrolyte is a strong acid that
can burn skin and damage eyes.
------------------------------------------------------------------------
The RANGER 250 is shipped with the negative battery
cable disconnected. Make certain that the RUN-STOP
switch is in the STOP position. Remove the two screws
from the rear battery tray using a screwdriver or a 3/8"
socket. Attach the negative battery cable to the negative
battery terminal and tighten using a 1/2" socket or
wrench.
NOTE: This machine is furnished with a wet charged bat-
tery; if unused for several months, the battery may
require a booster charge. Be careful to charge the bat-
tery with the correct polarity.
----------------------------------------------------------------------------

MUFFLER OUTLET PIPE

Using the clamp provided secure the outlet pipe to the
outlet tube with the pipe positioned such that it will direct
the exhaust in the desired direction. Tighten using a
9/16" socket or wrench.

SPARK ARRESTER

Some federal, state or local laws may require that gaso-
line or diesel engines be equipped with exhaust spark
arresters when they are operated in certain locations
where unarrested sparks may present a fire hazard. The
standard muffler included with this welder does not quali-
fy as a spark arrester. When required by local regula-
tions, a suitable spark arrester, such as the K1898-1
must be installed and properly maintained.
