BE SURE THAT ALL INSTALLATION, OPERATION,
MAINTENANCE AND REPAIR PROCEDURES ARE
PERFORMED ONLY BY QUALIFIED INDIVIDUALS.
FOR ENGINE POWERED
EQUIPMENT.
1.a. Turn the engine off before troubleshooting
and maintenance work unless the
maintenance work requires it to be running.
with hot engine parts and igniting. Do not spill fuel when filling
tank. If fuel is spilled, wipe it up and do not start engine until
fumes have been eliminated.
1.d. Keep all equipment safety guards, covers
and devices in position and in good repair.
Keep hands, hair, clothing and tools away
from V-belts, gears, fans and all other
moving parts when starting, operating or
repairing equipment.
1.e. In some cases it may be necessary to remove safety guards to
perform required maintenance. Remove guards only when
necessary and replace them when the maintenance requiring
their removal is complete. Always use the greatest care when
working near moving parts.
1.f. Do not put your hands near the engine fan. Do not attempt to
override the governor or idler by pushing on the throttle control
rods while the engine is running.
1.g. To prevent accidentally starting gasoline engines while turning
the engine or welding generator during maintenance work,
disconnect the spark plug wires, distributor cap or magneto wire
as appropriate.
1.h. To avoid scalding, do not remove the radiator
pressure cap when the engine is hot.
ELECTRIC AND
MAGNETIC FIELDS MAY
BE DANGEROUS
2.a. Electric current flowing through any conductor
causes localized Electric and Magnetic Fields (EMF).
Welding current creates EMF fields around welding cables
and welding machines
2.b. EMF fields may interfere with some pacemakers, and
welders having a pacemaker should consult their physician
before welding.
2.c. Exposure to EMF fields in welding may have other health effects
which are now not known.
2.d. All welders should use the following procedures in order to
minimize exposure to EMF fields from the welding circuit:
2.d.1. Route the electrode and work cables together - Secure
them with tape when possible.
2.d.2. Never coil the electrode lead around your body.
2.d.3. Do not place your body between the electrode and work
cables. If the electrode cable is on your right side, the
work cable should also be on your right side.
2.d.4. Connect the work cable to the workpiece as close as possible to the area being welded.
2.d.5. Do not work next to welding power source.
1.b. Operate engines in open, well-ventilated areas or vent the engine
exhaust fumes outdoors.
1.c. Do not add the fuel near an open flame welding
arc or when the engine is running. Stop the
engine and allow it to cool before refueling to
prevent spilled fuel from vaporizing on contact
Safety 02 of 04 - 5/16/2018
SAFETY
ELECTRIC SHOCK
CAN KILL.
ARC RAYS CAN BURN.
3.a. The electrode and work (or ground) circuits are
electrically “hot” when the welder is on. Do
not touch these “hot” parts with your bare skin or wet clothing.
Wear dry, hole-free gloves to insulate hands.
4.a.
Use a shield with the proper filter and cover plates to protect your
eyes from sparks and the rays of the arc when welding or
observing open arc welding. Headshield and filter lens should
conform to ANSI Z87. I standards.
3.b. Insulate yourself from work and ground using dry insulation.
Make certain the insulation is large enough to cover your full area
of physical contact with work and ground.
4.b.
Use suitable clothing made from durable flame-resistant material
to protect your skin and that of your helpers from the arc rays.
4.c.
Protect other nearby personnel with suitable, non-flammable
screening and/or warn them not to watch the arc nor expose
themselves to the arc rays or to hot spatter or metal.
In addition to the normal safety precautions, if
welding must be performed under electrically
hazardous conditions (in damp locations or while
wearing wet clothing; on metal structures such as
floors, gratings or scaffolds; when in cramped
positions such as sitting, kneeling or lying, if there
is a high risk of unavoidable or accidental contact
with the workpiece or ground) use the following
equipment:
• Semiautomatic DC Constant Voltage (Wire) Welder.
• DC Manual (Stick) Welder.
• AC Welder with Reduced Voltage Control.
3.c. In semiautomatic or automatic wire welding, the electrode,
electrode reel, welding head, nozzle or semiautomatic welding
gun are also electrically “hot”.
3.d. Always be sure the work cable makes a good electrical
connection with the metal being welded. The connection should
be as close as possible to the area being welded.
3.e. Ground the work or metal to be welded to a good electrical (earth)
ground.
3.f. Maintain the electrode holder, work clamp, welding cable and
welding machine in good, safe operating condition. Replace
damaged insulation.
3.g. Never dip the electrode in water for cooling.
3.h. Never simultaneously touch electrically “hot” parts of electrode
holders connected to two welders because voltage between the
two can be the total of the open circuit voltage of both
welders.
3.i. When working above floor level, use a safety belt to protect
yourself from a fall should you get a shock.
3.j. Also see Items 6.c. and 8.
FUMES AND GASES
CAN BE DANGEROUS.
5.a. Welding may produce fumes and gases
hazardous to health. Avoid breathing these
fumes and gases. When welding, keep your head out of the fume.
Use enough ventilation and/or exhaust at the arc to keep fumes
and gases away from the breathing zone. When welding
hardfacing (see instructions on container or SDS)
or on lead or cadmium plated steel and other
metals or coatings which produce highly toxic
fumes, keep exposure as low as possible and
within applicable OSHA PEL and ACGIH TLV limits
using local exhaust or mechanical ventilation
unless exposure assessments indicate otherwise.
In confined spaces or in some circumstances,
outdoors, a respirator may also be required.
Additional precautions are also required when
welding
on galvanized steel.
5. b. The operation of welding fume control equipment is affected by
various factors including proper use and positioning of the
equipment, maintenance of the equipment and the specific
welding procedure and application involved. Worker exposure
level should be checked upon installation and periodically
thereafter to be certain it is within applicable OSHA PEL and
ACGIH TLV limits.
5.c. Do not weld in locations near chlorinated hydrocarbon vapors
coming from degreasing, cleaning or spraying operations. The
heat and rays of the arc can react with solvent vapors to form
phosgene, a highly toxic gas, and other irritating products.
5.d. Shielding gases used for arc welding can displace air and cause
injury or death. Always use enough ventilation, especially in
confined areas, to insure breathing air is safe.
5.e. Read and understand the manufacturer’s instructions for this
equipment and the consumables to be used, including the
Safety Data Sheet (SDS) and follow your employer’s safety
practices. SDS forms are available from your welding
distributor or from the manufacturer.
5.f. Also see item 1.b.
Safety 03 of 04 - 5/16/2018
SAFETY
WELDING AND CUTTING
SPARKS CAN CAUSE
FIRE OR EXPLOSION.
6.a. Remove fire hazards from the welding area. If
this is not possible, cover them to prevent the welding sparks
from starting a fire. Remember that welding sparks and hot
materials from welding can easily go through small cracks and
openings to adjacent areas. Avoid welding near hydraulic lines.
Have a fire extinguisher readily available.
6.b. Where compressed gases are to be used at the job site, special
precautions should be used to prevent hazardous situations.
Refer to “Safety in Welding and Cutting” (ANSI Standard Z49.1)
and the operating information for the equipment being used.
6.c. When not welding, make certain no part of the electrode circuit is
touching the work or ground. Accidental contact can cause
overheating and create a fire hazard.
6.d. Do not heat, cut or weld tanks, drums or containers until the
proper steps have been taken to insure that such procedures
will not cause flammable or toxic vapors from substances inside.
They can cause an explosion even though they have been
“cleaned”. For information, purchase “Recommended Safe
Practices for the Preparation for Welding and Cutting of
Containers and Piping That Have Held Hazardous Substances”,
AWS F4.1 from the American Welding Society
(see address above).
6.e. Vent hollow castings or containers before heating, cutting or
welding. They may explode.
6.f. Sparks and spatter are thrown from the welding arc. Wear oil free
protective garments such as leather gloves, heavy shirt, cuffless
trousers, high shoes and a cap over your hair. Wear ear plugs
when welding out of position or in confined places. Always wear
safety glasses with side shields when in a welding area.
6.g. Connect the work cable to the work as close to the welding area
as practical. Work cables connected to the building framework or
other locations away from the welding area increase the
possibility of the welding current passing through lifting chains,
crane cables or other alternate circuits. This can create fire
hazards or overheat lifting chains or cables until they fail.
6.h. Also see item 1.c.
6.I. Read and follow NFPA 51B “Standard for Fire Prevention During
Welding, Cutting and Other Hot Work”, available from NFPA, 1
Batterymarch Park, PO box 9101, Quincy, MA 022690-9101.
6.j. Do not use a welding power source for pipe thawing.
CYLINDER MAY EXPLODE IF
DAMAGED.
7.a. Use only compressed gas cylinders containing
the correct shielding gas for the process used
and properly operating regulators designed for
the gas and pressure used. All hoses, fittings,
etc. should be suitable for the application and
maintained in good condition.
7.b. Always keep cylinders in an upright position securely chained to
an undercarriage or fixed support.
7.c. Cylinders should be located:
•
Away from areas where they may be struck or subjected
to physical damage.
•
A safe distance from arc welding or cutting operations
and any other source of heat, sparks, or flame.
7.d. Never allow the electrode, electrode holder or any other
electrically “hot” parts to touch a cylinder.
7.e. Keep your head and face away from the cylinder valve outlet
when opening the cylinder valve.
7.f. Valve protection caps should always be in place and hand tight
except when the cylinder is in use or connected for use.
7.g. Read and follow the instructions on compressed gas cylinders,
associated equipment, and CGA publication P-l, “Precautions for
Safe Handling of Compressed Gases in Cylinders,” available from
the Compressed Gas Association, 14501 George Carter Way
Chantilly, VA 20151.
FOR ELECTRICALLY
POWERED EQUIPMENT.
8.a. Turn off input power using the disconnect
switch at the fuse box before working on
the equipment.
8.b. Install equipment in accordance with the U.S. National Electrical
Code, all local codes and the manufacturer’s recommendations.
8.c. Ground the equipment in accordance with the U.S. National
Electrical Code and the manufacturer’s recommendations.

• Keep away from moving parts.
------------------------------------------------------------------------
See additional warning information at
front of this operator’s manual.
Only qualified personnel should install,
use, or service this equipment.
LOCATION AND VENTILATION
The welder should be located to provide an unrestricted flow of clean, cool air to the cooling air inlets and to
avoid restricting the cooling air outlets. Also, locate the
welder so that the engine exhaust fumes are properly
vented to an outside area.
STACKING
Ranger® 305D (AU) machines cannot be stacked.
ANGLE OF OPERATION
Engines are designed to run in the level condition
which is where the optimum performance is achieved.
The maximum angle of continuous operation is 20
degrees in all directions, 35 degrees Intermittent (less
than 10 minutes continuous) in all directions. If the
engine is to be operated at an angle, provisions must
be made for checking and maintaining the oil level at
the normal (FULL) oil capacity in the crankcase.
When operating the welder at an angle, the effective
fuel capacity will be slightly less than the specified 12

fuel). A lift bail is mounted to the machine and should
always be used when lifting the machine.
HIGH ALTITUDE OPERATION
At higher altitudes, output derating may be necessary. For maximum rating, derate the machine 2.5% to 3.5% for every 1000 ft.
(305m). Due to new EPA and other local emissions regulations,
modifications to the engine for high altitude are restricted within
the United States and some other European Countries. Use
above 6000 ft.(1828 m) may be limited due to poor engine performance or excessive exhaust smoke. An authorized Kubota
engine field service shop should be contacted to determine if
any adjustments can be made for operation in higher elevations
locally.
HIGH TEMPERATURE OPERATION
At temperatures above 104°F(40°C), Welder output derating is
necessary. For maximum output ratings, derate the welder output 2 volts for every 50°F(10°C) above 104°F(40°C).
Cold weather starting:
With a fully charged battery and the proper weight oil,
the engine should start satisfactorily even down to
about 5°F (-15°C). If the engine must be frequently
started at or below 23°F (-5°C), it may be desirable to
install cold-starting aides. The use of No. 1D diesel
fuel is recommended in place of No. 2D at temperatures below 23°F (-5°C). Allow the engine to warm up
before applying a load or switching to high idle.
WARNING
Note: Extreme cold weather starting may require
longer glow plug operation.
Under no conditions should ether or other starting
fluids be used with this engine!

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 dangerous electric shock, other equipment
to which this engine driven welder supplies power
WARNING
must:
• 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.

INSTALLATION
A-5
When this welder is mounted on a truck or trailer, its
frame must be electrically bonded to the metal frame
of the vehicle. Use a #8 or larger copper wire connected between the machine grounding stud and the
frame of the vehicle. When this engine driven welder
is connected to premises wiring such as that in a
home or shop, its frame must be connected to the system earth ground. See further connection instructions
in the section entitled "Standby Power Connections"
as well as the article on grounding in the latest
National Electrical Code and the local code.
In general, if the machine is to be grounded, it should
be connected with a #8 or larger copper wire to a solid
earth ground such as a metal water pipe going into the
ground for at least ten feet and having no insulated
joints, or to the metal framework of a building which
has been effectively grounded.
The National Electrical Code lists a number of alternate means of grounding electrical equipment. A
machine grounding stud marked with the symbol
is provided on the front of the welder.

WELDING CONTROLS (Figure B.1)
1. OUTPUT CONTROL- The OUTPUT dial is
used to preset the output voltage or current as displayed on the digital meters for the four welding
modes. When in the CC-STICK, DOWNHILL PIPE
or CV-WIRE modes and when a remote control is
connected to the 6-Pin or 14-Pin Connector, the
auto-sensing circuit automatically switches the
OUTPUT CONTROL from control at the welder to
the remote control.
In the CV-WIRE mode, when the wire feeder control cable is connected to the 14-Pin Connector, the
auto-sensing circuit automatically makes OUTPUT
CONTROL inactive and the wire feeder voltage
control active.
When in the TOUCH START TIG mode and when a
Amptrol is connected to the 6-Pin Connector, the
OUTPUT dial is used to set the maximum current
range of the CURRENT CONTROL of the Amptrol.

2. DIGITAL OUTPUT METERS- The digital
meters allow the output voltage (CV-WIRE mode)
or current (CC-STICK,DOWN HILL PIPE and TIG
modes) to be set prior to welding using the OUTPUT control dial. During welding, the meter display the actual output voltage (VOLTS) and current (AMPS). A memory feature holds the display
of both meters on for seven seconds after welding
is stopped. This allows the operator to read the
actual current and voltage just prior to when welding was ceased.
While the display is being held the left-most decimal point in each display will be flashing. The
accuracy of the meters is +/- 3%.

OPERATION
4. ARC CONTROL- The ARC CONTROL dial is active in
the CV-WIRE, CC-STICK and DOWNHILL PIPE modes,
and has different functions in these modes. This control is
not active in the TIG mode.
CC-STICK mode: In this mode, the ARC CONTROL dial
sets the short circuit current (arc-force) during stick welding
to adjust for a soft or crisp arc. Increasing the dial from –10
(soft) to +10 (crisp) increases the short circuit current and
prevents sticking of the electrode to the plate while welding.
This can also increase spatter. It is recommended that the
ARC CONTROL be set to the minimum number without
electrode sticking. Start with a setting at 0.
DOWNHILL PIPE mode: In this mode, the ARC CONTROL
dial sets the short circuit current (arc-force) during stick
welding to adjust for a soft or a more forceful digging arc
(crisp). Increasing the number from –10 (soft) to +10 (crisp)
increases the short circuit current which results in a more
forceful digging arc. Typically a forceful digging arc is preferred for root and hot passes. A softer arc is preferred for fill
and cap passes where weld puddle control and deposition
("stacking" of iron) are key to fast travel speeds. It is recommended that the ARC CONTROL be set initially at 0.
CV-WIRE mode: In this mode, turning the ARC CONTROL
clock wise from –10 (soft) to +10 (crisp) changes the arc
from soft and washed-in to crisp and narrow. It acts as an
inductance/pinch control. The proper setting depends on the
procedure and operator preference. Start with a setting of 0.
5. WELD OUTPUT TERMINALS WITH FLANGE
NUT- Provides a connection point for the electrode and
work cables.
6. GROUND STUD-

10. WIRE FEEDER VOLTMETER SWITCH:
Matches the polarity of the wire feeder voltmeter to
the polarity of the electrode.
ENGINE CONTROLS: (Figure B.2)
11. RUN/STOP SWITCH - RUN position energizes
the engine prior to starting. STOP position stops the
engine. The oil pressure interlock switch prevents
battery drain if the switch is left in the RUN position
and the engine is not operating.
12. GLOW PLUG PUSH BUTTON -
• When pushed activates the glow plugs. Glow plug
should not be activated for more than 20 seconds
continuously.
13. START PUSH BUTTON -
Energizes the starter motor to crank the engine.
14. IDLER SWITCH- Has two positions as follows:
1) In the HIGH position, the engine runs at the high
idle speed controlled by the engine governor.
2) In the AUTO position, the idler operates as follows:
• When switched from HIGH to AUTO or after starting
the engine, the engine will operate at full speed for
approximately 12 seconds and then go to low idle
speed.
• When the electrode touches the work or power is
drawn for lights or tools (approximately 100 Watts
minimum), the engine accelerates and operates at
full speed.
• When welding ceases or the AC power load is
turned off, a fixed time delay of approximately 12
seconds starts. If the welding or AC power load is
not restarted before the end of the time delay, the
idler reduces the engine speed to low idle speed.
• The engine will automatically return to high idle
speed when there is welding load or AC power load
reapplied.
WELD TERMINALS ON position, the output is electrically
hot all the time. In the REMOTELY CONTROLLED position, the output is controlled by a wire feeder or amptrol
device, and is electrically off until a remote switch is
depressed.

B-6
The Ranger® 305D (AU) can be used with a broad range
of DC stick electrodes. The MODE switch provides two
stick welding settings as follows:
It is recommended that the ARC CONTROL be set to the
minimum number without electrode sticking. Start with
the dial set at 0.
The CC-STICK position of the MODE switch is designed
for horizontal and vertical-up welding with all types of
electrodes, especially low hydrogen. The output CONTROL dial adjusts the full output range for stick welding.
The TOUCH START TIG setting of the MODE switch is
for DC TIG (Tungsten Inert Gas) welding. To initiate a
weld, the CONTROL dial is first set to the desired current
and the tungsten is touched to the work. During the time
the tungsten is touching the work there is very little voltage or current and, in general, no tungsten contamination. Then, the tungsten is gently lifted off the work in a
rocking motion, which establishes the arc.
Constant Current (CC-STICK) Welding
The ARC CONTROL dial sets the short circuit current
(arc-force) during stick welding to adjust for a soft or
crisp arc. Increasing the number from -10(soft) to
+10(crisp) increases the short circuit current and prevents sticking of the electrode to the plate while welding.
This can also increase spatter. It is recommended that
the ARC CONTROL be set to the minimum number without electrode sticking. Start with the dial set at 0.
TIG WELDING
When in the TOUCH START TIG mode and when a
Amptrol is connected to the 6-Pin connector the OUTPUT dial is used to set the maximum current range of the
current control of the Amptrol.

Engine Oil Change
Drain the engine oil while the engine is warm to
assure rapid and complete draining. It is recommended that each time the oil is changed the oil filter be
changed as well.
Oil Filter Change
• Drain the oil.
• Locate oil drain hose and valve in bottom of base
and pull through the hole in the battery access panel
on the welder.
• Clean the filter mounting base and coat the gasket
of the new filter with clean engine oil.
• Be sure the unit is off. Disconnect the negative battery cable to ensure safety.
• Remove the cap from the drain valve. Push valve in
and twist counterclockwise. Pull to open and drain
the oil into a suitable container for disposal.
• Close the drain valve by pushing in and twisting
clockwise. Replace the cap.
• Re-fill the crankcase to the upper limit mark on the
dipstick with the recommended oil (see engine operation manual OR engine service items decal OR
below). Replace and tighten the oil filler cap securely.
• Push oil drain hose and valve back into unit, re-connect negative battery cable, and close doors and
engine top cover before restarting unit.Wash your
hands with soap and water after handling used
motor oil. Please dispose of used motor oil in a
manner that is compatible with the environment.
We suggest you take it in a sealed container to your
local service station or recycling center for reclamation. DO NOT throw it in the trash; pour it on the
ground or down a drain.
Engine Oil Refill capacities
Without oil filter replacement:
• 3.3 U.S. Quart. (2.7 Imp Quart, 3.2 liter)
With oil filter replacement:
• 3.4 U.S. Quart. (3.0 Imp Quart, 3.2 liter)
• Remove the oil filter with an oil filter wrench and
drain the oil into a suitable container. Discard the
used filter. Note: Care should be taken during filter
removal to not disrupt or damage in any way the fuel
lines.
• Screw the new filter on by hand until the gasket contacts the mounting base. Using an oil filter wrench,
tighten the filter an additional 1/2 to 7/8 of a turn.
• Refill the crankcase with the specified amount of the
recommended engine oil. Reinstall the oil filler cap
and tighten securely.
• Start the engine and check for oil filter leaks.
• Stop the engine and check the oil level. If necessary, add oil to the upper limit mark on the dipstick.
WARNING
• Never use gasoline or low flash point solvents
for cleaning the air cleaner element. A fire or
explosion could result.
• Never run the engine without the air cleaner.
CAUTION
Rapid engine wear will result from contaminants,
such as dust and dirt being drawn into the
engine.
--------------------------------------------------------------------------------
AIR CLEANER
The diesel engine is equipped with a dry type air filter.
Never apply oil to it. Service the air cleaner as follows:
Use motor oil designed for diesel engines that meets
requirements for API service classification
CC/CD/CE/CF/CF-4/CG-4 or CH-4.
ACEA E1/E2/E3. Always check the API service label
on the oil container to be sure it includes the letters
indicated. (Note: An S-grade oil must not be used in a
diesel engine or damage may result. It IS permissible
to use an oil that meets S and C grade service classifications.)
SAE 10W30 is recommended for general, all temperature use, 5F to 104F (-15C to 40C).
See engine owner’s manual for more specific information on oil viscosity recommendations.
Replace the element at least every 200 hours of
operation and sooner under dusty conditions.

Service Instructions
Single- and Two-Stage Engine Air Cleaners
Inspect the New Filter for Damage
Remove the Filter
Rotate the
filter while
pulling
straight out.
Unfasten or unlatch the
service cover. Because
the filter fits tightly over the
outlet tube to create the critical seal, there will
be some initial resistance, similar to breaking
the seal on a jar. Gently move the end of the filter
back and forth to break the seal then rotate while
pulling straight out. Avoid knocking the filter
against the housing.
If your air cleaner has a safety filter, replace it every third primary
filter change. Remove the safety filter as you would the primary
filter. Make sure you cover the air cleaner outlet tube to avoid any
unfiltered contaminant dropping into the engine.
Clean Both Surfaces of the Outlet Tube
and Check the Vacuator™ Valve
Use a clean cloth to wipe the filter sealing surface and the inside of
the outlet tube. Contaminant on the sealing surface could hinder an
effective seal and cause leakage. Make sure that all contaminant is
removed before the new filter is inserted. Dirt accidently transferred
to the inside of the outlet tube will reach the engine and cause
wear. Engine manufacturers say that it takes only a few grams of
dirt to "dust" an engine! Be careful not to damage the sealing area
on the tube.
Wipe both sides
of the outlet
tube clean.
Outer edge of the
outlet tube
Inspect the new filter carefully, paying attention to
the inside of the open end, which is the
sealing area. NEVER install a damaged
filter. A new Donaldson radial seal
filter may have a dry lubricant on the
seal to aid installation.
Insert the New Radial Seal Filter Properly
If you're servicing the safety filter, this should be seated into
position before installing the primary filter.
Insert the new filter carefully. Seat
the filter by hand, making certain it is
completely into the air cleaner housing
before securing the cover in place.
The critical sealing area will stretch
slightly, adjust itself and distribute the sealing pressure evenly. To
complete a tight seal, apply pressure by hand at the outer rim of
the filter, not the flexible center. (Avoid pushing on the center of the
urethane end cap.) No cover pressure is required to hold the seal.
NEVER use the service cover to push the filter into place! Using the
cover to push the filter in could cause damage to the housing, cover
fasteners and will void the warranty.
If the service cover hits the filter before it is fully in place, remove
the cover and push the filter (by hand) further into the air cleaner
and try again. The cover should go on with no extra force.
Once the filter is in place, secure the service cover.
Inner edge of the
outlet tube
If your air cleaner is equipped with a Vacuator Valve
Visually check and physically squeeze to make sure the
valve is flexible and not inverted, damaged or plugged.
Caution
NEVER use the service cover to
push the filter into place! Using
the cover to push the filter in could
cause damage to the housing, cover
fasteners and will void the warranty.
Inspect the Old
Filter for Leak Clues
Visually inspect the old filter for any signs
of leaks. A streak of dust on the clean side
of the filter is a telltale sign. Remove any
cause of leaks before installing new filter.
Check Connectors for Tight Fit
Make sure that all mounting bands, clamps, bolts, and connections
in the entire air cleaner system are tight. Check for holes in piping
and repair if needed. Any leaks in your intake piping will send dust
directly to the engine!

FUEL
HOT COOLANT can burn skin.
• Do not remove cap if radiator is
hot.
-----------------------------------------------------------------------Check the coolant level by observing the level in the
radiator and recovery bottle. Add 50/50 antifreeze /
water solution if the level is close to or below the
"LOW" mark. do not fill above the "FULL" mark.
Remove radiator cap and add coolant to radiator. Fill
up to the top of the tube in the radiator filler neck
which includes a connecting hose coming from the
thermostat housing.
To drain the coolant, open the petcock at the bottom
of the radiator. Open the radiator cap to allow complete drainage. (Tighten the petcock and refill with a
50/50 antifreeze/water solution.) Use an automotive
grade (low silicate) ethylene glycol antifreeze. The
cooling system capacity is 3.85 quarts (3.6L.).
Squeeze upper and lower radiator hoses while filling
to bleed air from system coolant. Replace and tighten
the radiator cap.
CAUTION
Always premix the antifreeze and clean tap water
before adding to the radiator. It is very important
that a precise 50/50 solution be used with this
engine year round. This gives proper cooling during hot weather and freezing protection to -34° F
(-37° C).
Cooling solution exceeding 50% ethylene glycol
can result in engine overheating and damage to
the engine. Coolant solution must be premixed
before adding to radiator.
--------------------------------------------------------------------------------
Periodically remove the dirt from the radiator fins.
Periodically check the fan belt and radiator hoses.
Replace if signs of deterioration are found.
At the end of each day’s use, refill the fuel tank to minimize moisture condensation and dirt contamination in
the fuel line. Do not overfill; leave room for the fuel to
expand.
Use only fresh, No. 2 grade DIESEL fuel. Do not use
kerosene.
See the Engine Operator's Manual for instructions on
replacing the fuel filter.
BLEEDING THE FUEL SYSTEM
You may need to bleed air from the fuel system if the
fuel filter or fuel lines have been detached, the fuel
tank has been ran empty or after periods of long storage. It is recommended that the fuel shutoff valve be
closed during periods of non-use.
The Kubota D722 engine supplied with this welder is
equipped with an automatic bleeding mechanism that
helps purge the air from the mechanical fuel pump
system. It is generally not necessary to open a vent
screw or fuel line fitting to bleed the fuel system.
Operate the priming lever on the pump to assist starting after extended periods of non-use or out of fuel
conditions.
WARNING
To avoid personal injury, do not bleed a hot
engine. This could cause fuel to spill onto a hot
exhaust manifold, creating a danger of fire.
--------------------------------------------------------------------------------
Bleed the fuel system as follows:
1. Fill the fuel tank with fuel.
2. Open the fuel shut off valve (vertical position of
handle) on the Fuel Filter.
3. Crank the engine by pressing the start button for
45 seconds.
4. Check to see that fuel is flowing through both fuel
filters
5. Follow the normal STARTING procedures.
TIGHTENING THE FAN BELT
If the fan belt is loose, the engine can overheat and
the battery lose its charge. Check tightness by pressing on the belt midway between the pulleys. It should
deflect about .25 in. under a load of 20 lbs. (9 Kg) (6
mm).

CLEANING THE BATTERY
D-5
Keep the battery clean by wiping it with a damp cloth
when dirty. If the terminals appear corroded, disconnect the battery cables and wash the terminals with an
ammonia solution or a solution of 1/4 pound (0.1113
kg) of baking soda and 1 quart (0.9461) of water. Be
sure the battery vent plugs (if equipped) are tight so
that none of the solution enters the cells.
After cleaning, flush the outside of the battery, the battery compartment, and surrounding areas with clear
water. Coat the battery terminals lightly with petroleum
jelly or a non-conductive grease to retard corrosion.
Keep the battery clean and dry. Moisture accumulation on the battery can lead to more rapid discharge
and early battery failure.
CHECKING THE ELECTROLYTE LEVEL
If battery cells are low, fill them to the neck of the filler
hole with distilled water and recharge. If one cell is
low, check for leaks.
CHARGING THE BATTERY
When you charge, jump, replace, or otherwise connect battery cables to the battery, be sure the polarity
is correct. Improper polarity can damage the charging
circuit. The Ranger® 305D (AU) positive (+) battery
terminal has a red terminal cover.
If you need to charge the battery with an external
charger, disconnect the negative cable first, then the
positive cable before you attach the charger leads.
After the battery is charged, reconnect the positive
battery cable first and the negative cable last. Failure
to do so can result in damage to the internal charger
components.
Follow the instructions of the battery charger manufacturer for proper charger settings and charging time.
