PRE-OPERATION ENGINE SERVICE

WARNING

READ the engine operating and maintenance instruc- tions supplied with this machine.

Stop engine and allow to cool before fueling

Do not smoke when fueling

Fill fuel tank at a moderate rate and do not over- fill.

Wipe up spilled fuel and allow fumes to clear before starting engine

Keep sparks and flame away from tank.

------------------------------------------------------------------

OIL

The RANGER 305G 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

WARNING

Fill the fuel tank with clean, fresh fuel. The capacity of the fuel tank is 12 gallons (45.4 liters). When the fuel gauge reads empty the tank contains approximately 2 gallons of reserve fuel.

NOTE: The fuel tank is mounted below the engine so a fuel shutoff valve is not required.

------------------------------------------------------------------------

ENGINE COOLING SYSTEM

WARNING

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

CAUTION

Use caution as the electrolyte is a strong acid that can burn skin and damage eyes.

------------------------------------------------------------------------

The RANGER 305G 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.

CAUTION

An incorrect spark arrestor 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 305G. The RANGER 305G and any high frequency generating equipment must be properly grounded. See the K930-2 Operating Manual for com- pleted instructions on installation, operation, and maintenance.

REMOTE CONTROL

The RANGER 305G is equipped with a 6 pin and a 14 pin Amphenol connector. The 6 pin connector is for connecting the K857 or K857-1 Remote Control (optional) or for TIG welding, the K870 foot Amptrol or the K812 hand Amptrol.

When in the CC-STICK, PIPE, and CV-WIRE modes and when a remote control is connected to the Amphenol, the auto-sensing circuit in the RANGER 305G automatically switches the OUTPUT control from control at the welder to remote control.
