PRE-OPERATION ENGINE SERVICE
READ the engine operating and maintenance instruc-
tions supplied with this machine.

• Do not smoke when fueling
• Fill fuel tank at a moderate rate and do not overfill

starting engine
• Keep sparks and flame away from tank
-------------------------------------------------------------------------------
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 run-
ning time during the first 25 running hours. Refer to
the engine Operator’s Manual for specific oil recom-
mendations and break-in information. The oil change
interval is dependent on the quality of the oil and the
operating environment. Refer to the Engine Operator’s
Manual for the proper service and maintenance inter-
vals.
FUEL
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 (45.4 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 bat-
tery 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
battery; 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
gasoline 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 qualify as a spark arrester. When required
by local regulations, a suitable spark arrester, such as
the S24647 must be installed and properly main-
tained.
An incorrect spark arrester may lead to damage to
the engine or adversely affect performance.

HIGH FREQUENCY GENERATORS FOR
TIG APPLICATIONS
The K930-2 TIG Module is suitable for use with the
Ranger 250. The Ranger 250 and any high frequency
generating equipment must be properly grounded.
See the K930-2 Operating Manual for completed
instructions on installation, operation, and mainte-
nance.
REMOTE CONTROL
The Ranger 250 is equipped with a 6 pin and a 14 pin
Amphenol connector. The 6 pin connector is for con-
necting the K857 or K857-1 Remote Control (optional)
or for TIG welding, the K870 foot Amptrol or the K812
hand Amptrol.
