WARNING
Mar ʻ95
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.h. To avoid scalding, do not remove the
radiator pressure cap when the engine is
hot.

SAFETY
ii
ARC RAYS can burn.
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.
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.
ELECTRIC SHOCK can
kill.
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.
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.
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 with electrodes which require special
ventilation such as stainless or hard facing (see
instructions on container or MSDS) or on lead or
cadmium plated steel and other metals or coatings
which produce highly toxic fumes, keep exposure as
low as possible and below Threshold Limit Values (TLV)
using local exhaust or mechanical ventilation. In
confined spaces or in some circumstances, outdoors, a
respirator may 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 spe-
cific 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 prod-
ucts.
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 manufacturerʼs instructions for this
equipment and the consumables to be used, including the
material safety data sheet (MSDS) and follow your
employerʼs safety practices. MSDS forms are available from
your welding distributor or from the manufacturer.
5.f. Also see item 1.b.
AUG 06
FOR ELECTRICALLY
powered equipment.

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 manufacturerʼs
recommendations.
8.c. Ground the equipment in accordance with the U.S. National
Electrical Code and the manufacturerʼs recommendations.
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,

Jan, 07
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 cir-
cuits. 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.

PRÉCAUTIONS DE SÛRETÉ
Pour votre propre protection lire et observer toutes les instructions
et les précautions de sûreté specifiques qui parraissent dans ce
manuel aussi bien que les précautions de sûreté générales suiv-
antes:
Sûreté Pour Soudage A LʼArc
1. Protegez-vous contre la secousse électrique:
a. Les circuits à lʼélectrode et à la piéce sont sous tension
quand la machine à souder est en marche. Eviter toujours
tout contact entre les parties sous tension et la peau nue
ou les vétements mouillés. Porter des gants secs et sans
trous pour isoler les mains.
b. Faire trés attention de bien sʼisoler de la masse quand on
soude dans des endroits humides, ou sur un plancher
metallique ou des grilles metalliques, principalement dans
les positions assis ou couché pour lesquelles une grande
partie du corps peut être en contact avec la masse.
c. Maintenir le porte-électrode, la pince de masse, le câble
de soudage et la machine à souder en bon et sûr état
defonctionnement.
d.Ne jamais plonger le porte-électrode dans lʼeau pour le
refroidir.
e. Ne jamais toucher simultanément les parties sous tension
des porte-électrodes connectés à deux machines à souder
parce que la tension entre les deux pinces peut être le
total de la tension à vide des deux machines.
f. Si on utilise la machine à souder comme une source de
courant pour soudage semi-automatique, ces precautions
pour le porte-électrode sʼapplicuent aussi au pistolet de
soudage.
2. Dans le cas de travail au dessus du niveau du sol, se protéger
contre les chutes dans le cas ou on recoit un choc. Ne jamais
enrouler le câble-électrode autour de nʼimporte quelle partie
du corps.
3. Un coup dʼarc peut être plus sévère quʼun coup de soliel,
donc:
a. Utiliser un bon masque avec un verre filtrant approprié
ainsi quʼun verre blanc afin de se protéger les yeux du ray-
onnement de lʼarc et des projections quand on soude ou
quand on regarde lʼarc.
b. Porter des vêtements convenables afin de protéger la
peau de soudeur et des aides contre le rayonnement de
lʻarc.
c. Protéger lʼautre personnel travaillant à proximité au
soudage à lʼaide dʼécrans appropriés et non-inflammables.
4. Des gouttes de laitier en fusion sont émises de lʼarc de
soudage. Se protéger avec des vêtements de protection libres
de lʼhuile, tels que les gants en cuir, chemise épaisse, pan-
talons sans revers, et chaussures montantes.
5. Toujours porter des lunettes de sécurité dans la zone de
soudage. Utiliser des lunettes avec écrans lateraux dans les
zones où lʼon pique le laitier.
6. Eloigner les matériaux inflammables ou les recouvrir afin de
prévenir tout risque dʼincendie dû aux étincelles.
7. Quand on ne soude pas, poser la pince à une endroit isolé de
la masse. Un court-circuit accidental peut provoquer un
échauffement et un risque dʼincendie.
8. Sʼassurer que la masse est connectée le plus prés possible
de la zone de travail quʼil est pratique de le faire. Si on place
la masse sur la charpente de la construction ou dʼautres
endroits éloignés de la zone de travail, on augmente le risque
de voir passer le courant de soudage par les chaines de lev-
age, câbles de grue, ou autres circuits. Cela peut provoquer
des risques dʼincendie ou dʼechauffement des chaines et des
câbles jusquʼà ce quʼils se rompent.
9. Assurer une ventilation suffisante dans la zone de soudage.
Ceci est particuliérement important pour le soudage de tôles
galvanisées plombées, ou cadmiées ou tout autre métal qui
produit des fumeés toxiques.
10. Ne pas souder en présence de vapeurs de chlore provenant
dʼopérations de dégraissage, nettoyage ou pistolage. La
chaleur ou les rayons de lʼarc peuvent réagir avec les vapeurs
du solvant pour produire du phosgéne (gas fortement toxique)
ou autres produits irritants.
11. Pour obtenir de plus amples renseignements sur la sûreté,
voir le code “Code for safety in welding and cutting” CSA
Standard W 117.2-1974.
PRÉCAUTIONS DE SÛRETÉ POUR
LES MACHINES À SOUDER À
TRANSFORMATEUR ET À
REDRESSEUR
1. Relier à la terre le chassis du poste conformement au code de
lʼélectricité et aux recommendations du fabricant. Le dispositif
de montage ou la piece à souder doit être branché à une
bonne mise à la terre.
2. Autant que possible, Iʼinstallation et lʼentretien du poste seront
effectués par un électricien qualifié.
3. Avant de faires des travaux à lʼinterieur de poste, la debranch-
er à lʼinterrupteur à la boite de fusibles.
4. Garder tous les couvercles et dispositifs de sûreté à leur
place.

dard.
Air Cleaner - Heavy duty two stage dry type.
Muffler - A muffler and stainless steel exhaust outlet
elbow are standard.
Engine Hour Meter - A meter to record hours of oper-
ation.
Engine Protection - The system shuts the engine
down in the event of sudden low oil pressure or high
coolant temperature. A warning light on the control
panel will indicate such a fault. To reset the engine for
restarting, turn the ignition switch off then on.
Refer to Troubleshooting section for all warning light
fault codes.

EXHAUST SPARK ARRESTER
Some federal, state or local laws may require that 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 must
be installed and properly maintained.
Use of an incorrect arrester may lead to engine damage or
performance loss. Contact the engine manufacturer for spe-
cific recommendations.
--------------------------------------------------------------------------------
LOCATION/VENTILATION
Always operate the welder with the doors closed. Leaving the
doors open changes the designed air flow and may cause
overheating.
The welder should be located to provide an unrestricted flow
of clean, cool air. Also, locate the welder so that engine
exhaust fumes are properly vented to an outside area.
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,
30 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 amount specified.
MACHINE GROUNDING
According to the United States National Electrical Code, the
frame of this portable generator is not required to be grounded
and is permitted to serve as the grounding means for cord
connected equipment plugged into its receptacle.
Some state, local, or other codes or unusual operating circum-
stances may require the machine frame to be grounded. It is
recommended that you determine the extent to which such
requirements may apply to your particular situation and follow
them explicitly. A machine grounding stud marked with the
symbol is provided on the welding generator frame foot. In
general, if the machine is to be grounded, it should be con-
nected 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 frame-
work of a building which has been effectively grounded. The
U.S. National Code lists a number of alternate means of
grounding electrical equipment.
LIFT BAIL
A lift bail is provided for lifting with a hoist.
Do not attempt to use this equipment until you have
thoroughly read the engine manufacturerʼs manual sup-
plied with your welder. It includes important safety pre-
cautions, detailed engine starting, operating and main-
tenance instructions, and parts lists.

TRAILER (See Optional Features)
If the user adapts a non-Lincoln trailer, the user must
assume responsibility that the method of attachment
and usage does not result in a safety hazard nor dam-
age the welding equipment. Some of the factors to be
considered are as follows:
1. Design capacity of trailer vs. weight of Lincoln
equipment and likely additional attachments.
2. Proper support of, and attachment to, the base of
the welding equipment so there will be no undue
stress to the framework.
3. Proper placement of the equipment on the trailer to
ensure stability side to side and front to back when
being moved and when standing by itself while
being operated or serviced.
4. Typical conditions of use, i.e., travel speed, rough-
ness of surface on which the trailer will be operat-
ed; environmental conditions, likely maintenance.
5. Conformance with federal, state and local laws.

WARNING
COLD WEATHER STARTING:
With a fully charged battery and the proper weight oil,
the engine should start satisfactorily even down to
about -5°F (-20°C), it maybe desirable to install cold-
starting aides.
Note: Extreme cold weather staring may require
longer glow plug operation.
Under NO
conditions should ether or other
starting fluids be used!
------------------------------------------------------------------------
HIGH ALTITUDE OPERATION:
At higher altitudes, output derating may be necessary.
For maximum rating, derate the welder 4% for every
300 meters (984 ft.) above 1500 meters (4920 ft.).
Contact a Kubota Service Representative for any
engine adjustments that may be required.
STOPPING THE ENGINE
1. Turn the “IGNITION” switch to “OFF”
At the end of each dayʼs welding, check the crankcase
oil level, drain accumulated dirt and water from the
water separator and refill the fuel tank to minimize
moisture condensation in the tank. Also, running out
of fuel tends to draw dirt into the fuel system.
When hauling the welder between job sites, close the
valve on the water separator.
If the fuel supply is cut off or runs out while the fuel
pump is operating, air may be entrapped in the fuel
distribution system. If this happens, bleeding of the
fuel system may be necessary. Use qualified person-
nel to do this per the instructions in the MAINTE-
NANCE section of this manual.
ENGINE BREAK-IN
Lincoln Electric selects high quality, heavy-duty indus-
trial 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, wet stacking (oil or tar like sub-
stance at the exhaust port), or excessive smoke is not
normal.

CLASSIC 300D KUBOTA
WELDER OPERATION
------------------------------------------------------------------------
DUTY CYCLE
The NEMA output rating of the CLASSIC 300D KUB-
OTA is 300 amperes at 32 arc volts on
a 60% duty
cycle (consult Specifications in this manual
for alter-
nate ratings). Duty cycle is based on a ten minute
period; thus, the welder can be loaded at rated output
for six minutes out of every ten minute period.
CONTROL OF WELDING CURRENT
DO NOT TURN THE “CURRENT RANGE SELEC-
TOR” WHILE WELDING because the current may
arc between the contacts and damage the switch.
------------------------------------------------------------------------
The “Current Range Selector” provides five overlap-
ping current ranges. The “Fine Current Adjustment”
adjusts the current from minimum to maximum within
each range. Open circuit voltage is also controlled by
the “Fine Current Adjustment” permitting control of the
arc characteristics.
A high open circuit voltage setting provides the soft
“buttering” arc with best resistance to pop-outs pre-
ferred for most welding. To get this characteristic, set
the “Current Range Selector” to the lowest setting that
still provides the current you need and set the “Fine
Current Adjustment” near maximum. For example: to
obtain 175 amps and a soft arc, set the “Current
Range Selector” to the 190-120 position and then
adjust the “Fine Current Adjustment” for 175 amps.
When a forceful “digging” arc is required, usually for
vertical and overhead welding, use a higher “Current
Range Selector” setting and lower open circuit volt-
age. For example: to obtain 175 amps and a forceful
arc, set the “Current Range Selector” to the 240-160
position and the “Fine Current Adjustment” setting to
get 175 amps.
Some arc instability may be experienced with EXX10
electrodes when trying to operate with long arc tech-
niques at settings at the lower end of the open circuit
voltage range.
DO NOT attempt to set the “Current Range Selector”
between the five points designated on the nameplate.
------------------------------------------------------------------------
These switches have a spring loaded cam which
almost eliminates the possibility of setting this switch
between the designated points.
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts or
electrode with skin or wet clothing.
• Insulate yourself from work and ground.
FUMES & GASES can be dangerous.
• Keep your head out of the fumes.
• Use ventilation or exhaust to remove
fumes from breathing zone.
WELDING SPARKS can cause fire or
explosion.
• Keep flammable material away.
ARC RAYS can burn.
• Wear eye, ear, and body protection.
WARNING
CAUTION
CAUTION
Larger machines with a capacity of 350 amperes and
higher, which are operated at low or no-load condi-
tions for extended periods of time are especially sus-
ceptible to the conditions described above. To
accomplish successful engine break-in, most diesel-
powered equipment needs only to be run at a reason-
ably heavy load within the rating of the welder for
some period of time during the engineʼs early life.
However, if the welder is subjected to extensive light
loading, occasional moderate to heavy loading of the
engine may sometimes be necessary. 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 generator and voids
the warranty.
3. Periodically shut off the engine and check the
crankcase oil level.

IDLER OPERATION
Start the engine with the “Idler” switch in the “High”
position. Allow it to run at high idle speed for several
minutes to warm the engine. See Specifications for
operating speeds.
The idler is controlled by the “Idler” toggle switch on
the welder control panel. The switch has two posi-
tions as follows:
1. In the “High” position, the engine control unit
increases the engine to high idle speed.
2. In the “Auto” / position, the idler oper-
ates as follows:
a. When welding or drawing power for lights or tools
(approximately 100 watts minimum) from the recep-
tacles, the engine operates at high idle speed.
b. When welding ceases or the power load is turned
off, a preset time delay of about 15 seconds starts.
This time delay cannot be adjusted.
c. If the welding or power load is not re-started before
the end of the time delay, the engine control unit
reduces the engine to low idle speed.
AUXILIARY POWER
Start the engine and set the “IDLER” control switch to
the “High Idle” mode. Voltage is now correct at the
receptacles for auxiliary power. This must be done
before a tripped GFCI receptacle can be reset proper-
ly. See the MAINTENANCE section for detailed infor-
mation on testing and resetting the GFCI receptacle.

MAINTENANCE
GENERAL INSTRUCTIONS
1. Blow out the welder and controls with an air hose at
least once every two months. In particularly dirty
locations, this cleaning may be necessary once a
week. Use low pressure air to avoid driving dirt into
the insulation.
2. “Current Range Selector” contacts should not be
greased. To keep the contacts clean, rotate the cur-
rent control through its entire range frequently.
Good practice is to turn the handle from maximum
to minimum setting twice each morning before start-
ing to weld.
3. Put a drop of oil on the “Current Range Selector”
shaft at least once every month.
4
. Follow the engine service schedule in this manual
and the detailed maintenance and troubleshooting in
the engine manufacturerʼs manual.
COOLING SYSTEM
The CLASSIC 300D KUBOTA is equipped with a
pressure radiator. Keep the radiator cap tight to pre-
vent loss of coolant. Clean and flush the cooling sys-
tem periodically to prevent clogging the passage and
overheating the engine. When antifreeze is needed,
always use the permanent type.
BEARINGS
This welder is equipped with a double-shielded ball
bearing having sufficient grease to last indefinitely
under normal service. Where the welder is used con-
stantly or in excessively dirty locations, it may be nec-
essary to add one half ounce of grease per year. A
pad of grease one inch wide, one inch long, and one
inch high weighs approximately one half ounce. Over-
greasing is far worse than insufficient greasing.
When greasing the bearings, keep all dirt out of the
area. Wipe the fittings completely clean and use clean
equipment. More bearing failures are caused by dirt
introduced during greasing than from insufficient
grease.
COMMUTATOR AND BRUSHES
Uncovered rotating equipment can be dangerous.
Use care so your hands, hair, clothing or tools do
not catch in the rotating parts. Protect yourself
from particles that may be thrown out by the rotat-
ing armature when stoning the commutator.
------------------------------------------------------------------------
Shifting of the commutator brushes may result in:
- Change in machine output
- Commutator damage
- Excessive brush wear
Periodically inspect the commutator, slip rings, and
brushes by removing the covers. DO NOT remove or
replace these covers while the machine is running.
Commutators and slip rings require little attention.
However, if they are black or appear uneven, have
them cleaned by an experienced maintenance man
using fine sandpaper or a commutator stone. Never
use emery cloth or paper for this purpose.
CLASSIC 300D KUBOTA
Have qualified personnel do the maintenance
work. Turn the engine off before working inside
the machine. In some cases, it may be neces-
sary to remove safety guards to perform
required maintenance. Remove guards only
when necessary and replace them when the
maintenance requiring their removal is com-
plete. Always use the greatest care when work-
ing near moving parts.
Do not put your hands near the engine cooling
blower fan. If a problem cannot be corrected by
following the instructions, take the machine to
the nearest Lincoln Field Service Shop.

MAINTENANCE
D-2
Replace brushes when they wear within 1/4”(3.5mm)
of the pigtail. A complete set of replacement brushes
should be kept on hand. Lincoln brushes have a
curved face to fit the commutator. Have an experi-
enced maintenance man seat these brushes by lightly
stoning the commutator as the armature rotates at full
speed until contact is made across the full face of the
brushes. After stoning, blow out the dust with low
pressure air.
To seat slip ring brushes, position the brushes in
place. Then slide one end of a piece of fine sandpaper
between slip rings and brushes with the coarse side
against the brushes. With slight additional finger pres-
sure on top of the brushes, pull the sandpaper around
the circumference of the rings - in direction of rotation
only - until brushes seat properly. In addition, stone
slip ring with a fine stone. Brushes must be seated
100%.
Arcing or excessive exciter brush wear indicates a
possible misaligned shaft. Have an authorized Field
Service Shop check and realign the shaft.
IDLER MAINTENANCE
Before doing electrical work, disconnect the bat-
tery.
------------------------------------------------------------------------
When installing a new battery or using a jumper bat-
tery to start the engine, be sure the battery polarity is
connected properly. The correct polarity is negative
ground. Damage to the engine alternator and the
Engine Control Unit can result from incorrect connec-
tion.
1. Proper operation of the idler requires good
grounding of the Engine Control Unit, current
sensing printed circuit board and battery.
2. If desired, the welder can be used without automat-
ic idling by setting the “Idler” switch to the “High”
position.
NAMEPLATES
Whenever routine maintenance is performed on this
machine - or at least yearly - inspect all nameplates
and labels for legibility. Replace those which are no
longer clear. Refer to the parts list for the replace-
ment item number.
PURGING AIR FROM FUEL SYSTEM
(KUBOTA V2203M ENGINE)
Keep fuel clear of open flames or arcs, allow
engine to cool before working on the fuel system.
Wipe up any spilled fuel and do not start engine
until fumes clear.
------------------------------------------------------------------------
If the engine is running rough and you suspect air has
been trapped in the fuel system, (e.g. the engine was
allowed to run out of fuel) perform the following steps
using qualified personnel:
1.
Fully open the air bleeding valve by turning it
counter clockwise, it is located on top of the fuel
injection pump next to the oil filler. (see figure D.1)
FIGURE D.1
2. Turn the engine by pressing the start button until
the engine runs smoothly (this should take approxi-
mately 10 seconds).
3. Fully close the air bleeding valve by turning it
clockwise.
Contact your Kubota Engine repair facility if problems
persist.
