GENERAL DESCRIPTION

The RANGER® 305D is a diesel engine powered DC multi-process welding power source and 120 / 240 volt AC power generator. The engine drives a genera- tor that supplies three phase power for the DC weld- ing circuit and single phase power for the AC auxiliary outlets. The DC welding control system uses state of the art Chopper Technology (CT tm) for superior weld- ing performance.

FOR AUXILIARY POWER:

Start the engine and set the IDLER control switch to the desired operating mode. Full power is available regardless of the welding control settings providing no welding current is being drawn.

The auxiliary power of the RANGER® 305D consists of two 20 Amp-120 VAC (5-20R) duplex receptacles with GFCI protection and one 50 Amp 120/240 VAC (14-50R) receptacle. The 240 VAC receptacle can be split for single phase 120 VAC operation. Also refer to the AUXILIARY POWER OPERATION section later in this chapter.

ENGINE OPERATION

Before Starting the Engine:

•Be sure the machine is on a level surface.

•Open top & side engine doors and remove the engine oil dipstick and wipe it with a clean cloth. Reinsert the dipstick and check the level on the dip- stick.

•Add oil (if necessary) to bring the level up to the full mark. Do not overfill. Close engine door.

•Check radiator for proper coolant level. (Fill if nec- essary).

•See Engine Owner’s Manual for specific oil and coolant recommendations.

•Do not smoke when fueling.

•Keep sparks and flame away from tank.

•Do not leave unattended while fuel- ing.

DIESEL FUEL • Wipe up spilled fuel and allow fumes to clear before starting

engine.

• Do not overfill tank, fuel expan- sion may cause overflow.

DIESEL FUEL ONLY-Low sulphur fuel or ultra low sulphur fuel in U.S.A. and Canada.

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

•Remove the fuel tank cap.

•Fill the tank approximately 4 inches (100mm) from the top of the filler neck to allow for fuel expansion .

DO NOT FILL THE TANK TO THE POINT OF OVERFLOW.

•Replace the fuel cap and tighten securely.

•See Engine Owner’s Manual for specific fuel recom- mendations.

bREAK-IN PERIOD

Any engine will use a small amount of oil during its “break-in” period. For the diesel engine on the RANGER® 305D, break-in is about 50 running hours.

Check the oil every four hours during break-in. Change the oil after the first 50 hours of operation,every 100 hours thereafter. Change the oil filter at the second oil change.

CAUTION

During break-in, subject the RANGER® 305D to moderate loads. Avoid long periods running at idle. before stopping the engine, remove all loads and allow the engine to cool several minutes.
