SAFETY PRECAUTIONS
WARNING
Do not attempt to use this equipment until you have
thoroughly read the engine manufacturer's manual sup-
plied with your welder. It includes important safety pre-
cautions, detailed engine starting, operating and main-
tenance instructions, and parts lists.
------------------------------------------------------------------------
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts or
electrode with skin or wet clothing.
• Insulate yourself from work and ground
• Always wear dry insulating gloves.
• Always operate the welder with the hinged door closed
and the side panels in place.
• Read carefully the Safety Precautions page before
operating this machine. Always follow these and any
other safety procedures included in this manual and in
the Engine Instruction Manual.
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 generator that supplies three
phase power for the DC welding 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 welding 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 and one 50
Amp 120/240 VAC (14-50R) receptacle. The 240 VAC
receptacle can be split for single phase 120 VAC operation.
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 dip-
stick and check the level on the dipstick.
• 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 necessary).
• See Engine Owner's Manual for specific oil and coolant
recommendations.
OPERATION
ADD FUEL
• Remove the fuel tank cap.
• Fill the tank approximately 4 inches (100mm) from the top
of the filler neck to allow for fuel expansion (observe the
fuel gauge while filling). 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 recommenda-
tions.

can cause fire.

BREAK-IN PERIOD
Lincoln Electric selects high quality, heavy-duty industrial
engines for the portable welding machines we offer. While it is
normal to see a small amount of crankcase oil consumption
during initial operation, excessive oil use, wetstacking (oil or tar
like substance at the exhaust port), or excessive smoke is not
normal.
Larger machines with a capacity of 350 amperes and higher,
which are operated at low or no-load conditions for extended
periods of time are especially susceptible to the conditions
described above. To accomplish successful engine break-in,
most diesel-powered equipment needs only to be run at a rea-
sonably heavy load within the rating of the welder for some
period of time during the engine's early life. However, if the
welder is subjected to extensive light loading, occasional mod-
erate to heavy loading of the engine may sometimes be neces-
sary. Caution must be observed in correctly loading a
diesel/generator unit.
1. Connect the welder output studs to a suitable resistive load
bank. Note that any attempt to short the output studs by
connecting the welding leads together, direct shorting of the
output studs, or connecting the output leads to a length of
steel will result in catastrophic damage to the generator and
voids the warranty.
2. Set the welder controls for an output current and voltage
within the welder rating and duty cycle. Note that any
attempt to exceed the welder rating or duty cycle for any
period of time will result in catastrophic damage to the gen-
erator and voids the warranty.
3. Periodically shut off the engine and check the crankcase oil
level.

WARNING
• Stop engine while fueling.
• Do not smoke when fueling.
• Keep sparks and flame away
from tank.
• Do not leave unattended while
fueling.
• Wipe up spilled fuel and allow
fumes to clear before starting
engine.
• Do not overfill tank, fuel
expansion may cause overflow.
