OIL
The RANGER 250 LPG 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.
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 LPG 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 bat-
tery 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 LPG. The RANGER 250 LPG and any
high frequency generating equipment must be proper-
ly grounded. See the K930-2 Operating Manual for
completed instructions on installation, operation, and
maintenance.
REMOTE CONTROL
The RANGER 250 LPG is equipped with a 6 pin and a
14-pin connector. The 6-pin connector is for connect-
ing the K857 or K857-1 Remote Control (optional) or
for TIG welding, the K870 foot Amptrol or the K963-3
hand Amptrol.
When in the CC-STICK, DOWNHILL PIPE, and CV-
WIRE modes or when a remote control is connected
to the 6-pin connector, the auto-sensing circuit in the
RANGER 250 LPG automatically switches the OUT-
PUT control from control at the welder to remote con-
trol .
The 14-pin connector is used to directly connect a
wire feeder or TIG Module (K930-2) control cable. In
the CV-WIRE mode, the RANGER 250 LPG auto-
sensing circuit automatically makes the RANGER 250
LPG Output Control inactive and the remote voltage
control active when the control cable is connected to
the 14 pin connector.
When in the TOUCH START TIG mode and when a
Amptrol is connected to the 6 Pin connector the OUT-
PUT dial is used to set the maximum current range of
the CURRENT CONTROL of the Amptrol.
NOTE: When a wire feeder with a built in welding volt-
age control is connected to the 14 pin connector, do
not connect anything to the 6 pin connector.
