OIL

The RANGER® 305LPG 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

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 (Im) 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® 305LPG 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 K1898-1 must be installed and properly maintained.

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® 305LPG. The RANGER® 305LPG and any high frequency generating equipment must be properly grounded. See the K930-2 Operating Manual for completed instructions on installation, operation, and maintenance.

REMOTE CONTROL

The RANGER® 305LPG is equipped with a 6-pin and

a14-pin 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 K963- 3 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® 305LPG automatically switches the OUTPUT control from control at the welder to remote control.

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® 305LPG auto- sensing circuit automatically makes the RANGER® 305LPG Output Control inactive and the wire feeder voltage control active when the control cable is con- nected to the 14-pin connector.

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.

MACHINE GROUNDING

Because this portable engine driven welder creates its own power, it is not necessary to connect its frame to an earth ground, unless the machine is connected to premises wiring (home, shop, etc.) To prevent danger- ous electric shock, other equipment to which this engine driven welder supplies power must:

WARNING

•be grounded to the frame of the welder using a grounded type plug.

•be double insulated. Do not ground the machine to a pipe that carries explosive or combustible material.
