FOR ENGINE powered equipment.
1.a. Turn the engine off before troubleshooting and maintenance work unless the maintenance work requires it to be running.
____________________________________________________
1.b.Operate engines inopen, well-ventilated areas or ventthe 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 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 fumeshave 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 engineis running.
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 arenow 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 tapewhen 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. Ifthe electrode cable is on your right side, the work cable should also be on your right side.
___________________________________________________
1.g. To prevent accidentallystarting gasoline engines while turning the engine or welding generator during maintenance work, disconnect the spark plug wires, distributor cap or magneto wire asappropriate.
2.d.4. Connect the work cable to the workpiece as close as possible to thearea being welded.
2.d.5. Donot work next to welding power source.

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.
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.
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.
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.
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 coming from degreasing, cleaning or spraying operations. The heat and rays of the arc can react with solvent vapors 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 material safety data sheet (MSDS) and follow your employer’s safety practices. MSDS forms are available from your welding distributor or from the manufacturer.
5.f. Also see item 1.b.

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
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 been “cleaned”. For information, purchase “Recommended Safe Practices for the 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.
Sparks and spatter are thrown from the welding arc. Wear oil
6.f. 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.

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 suiv­antes:
Sûreté Pour Soudage A L’Arc
1. Protegez-vous contre la secousse électrique:
a. Les circuits à l’électrode 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 s’isoler 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 l’eau 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 s’applicuent 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 n’importe quelle partie du corps.
5. Toujours porter des lunettes de sécurité dans la zone de soudage. Utiliser des lunettes avec écrans lateraux dans les zones où l’on pique le laitier.
6. Eloigner les matériaux inflammables ou les recouvrir afin de prévenir tout risque d’incendie 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 d’incendie.
8. S’assurer que la masse est connectée le plus prés possible de la zone de travail qu’il est pratique de le faire. Si on place la masse sur la charpente de la construction ou d’autres endroits éloignés de la zone de travail, on augmente le risque de voir passer le courant de soudage par les chaines de lev­age, câbles de grue, ou autres circuits. Cela peut provoquer des risques d’incendie ou d’echauffement des chaines et des câbles jusqu’à ce qu’ils 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 d’opérations de dégraissage, nettoyage ou pistolage. La chaleur ou les rayons de l’arc 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
3. Un coup d’arc peut être plus sévère qu’un coup de soliel, donc:
a. Utiliser un bon masque avec un verre filtrant approprié
ainsi qu’un verre blanc afin de se protéger les yeux du ray­onnement de l’arc et des projections quand on soude ou quand on regarde l’arc.
b. Porter des vêtements convenables afin de protéger la
peau de soudeur et des aides contre le rayonnement de l‘arc.
c. Protéger l’autre personnel travaillant à proximité au
soudage à l’aide d’écrans appropriés et non-inflammables.
4. Des gouttes de laitier en fusion sont émises de l’arc de soudage. Se protéger avec des vêtements de protection libres de l’huile, tels que les gants en cuir, chemise épaisse, pan­talons sans revers, et chaussures montantes.
LES MACHINES À SOUDER À TRANSFORMATEUR ET À REDRESSEUR
1. Relier à la terre le chassis du poste conformement au code de l’électricité 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, I’installation et l’entretien du poste seront effectués par un électricien qualifié.
3. Avant de faires des travaux à l’interieur de poste, la debranch­er à l’interrupteur à la boite de fusibles.
4. Garder tous les couvercles et dispositifs de sûreté à leur place.

LOCATION/VENTILATION
ANGLE OF OPERATION
To achieve optimum engine performance the machine should be run in a level position. The maximum angle of operation for the Kubota engine is 20 degrees con­tinuous in all directions and 30 degeers intermittent (less then 10 minutes). 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 engine crankcase. When operating the welder at an angle, the effective fuel capacity will be slightly less than the specified 29 gallons.
LIFTING
The equipment lift bail should be used to lift the machine.
WARNING
• Lift only with equipment of ade­quate lifting capacity.
• Be sure machine is stable when lift­ing.
• Do not lift this machine using lift bail if it is equipped with a heavy accessory such as trailer or gas cylinder.
FALLING • Do not lift machine if lift bail is
damaged.

ENGINE BREAK-IN
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 diesel­powered equipment needs only to be run at a reason­ably 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 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.
ENGINE COOLING SYSTEM
The cooling system has been filled at the factory with a 50-50 mixture of ethylene glycol antifreeze and water. Check the radiator level and add a 50-50 solu­tion as needed. (See Engine Manual or antifreeze container for alternate antifreeze recommendation.)

SPARK ARRESTOR
WARNING
Some federal, state or local laws may require that diesel engines be equipped with exhaust spark arrestors when they are operated in certain locations where unarrested sparks may present a fire hazard.
The muffler included with this welder has been modi­fied and now qualifies as a spark arrestor. Spark arresting mufflers will have a clean out service plug and will have “US FOREST SERVICE APPROVED” stamped on the muffler shell. Any spark arrestor must be serviced and properly maintained.
CAUTION
An incorrect spark arrester may lead to damage to the engine or adversely affect performance.

WELDING OUTPUT CABLES
With the engine off, connect the electrode and work cables to the studs provided. These connections should be checked periodically and tightened if neces­sary.
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 powered by this engine driven welder must:
a) be grounded to the frame of the welder using a
grounded type plug,
or
b) be double insulated.
When this welder is mounted on a truck or trailer, its frame must be securely connected to the metal 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 the article on grounding in the latest U.S. 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 U.S. 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 welding generator frame foot.
Listed in Table A.1 are copper cable sizes recom­mended for the rated current and duty cycle. Lengths stipulated are the distance from the welder to work and back to the welder again. Cable sizes are increased for greater lengths primarily for the purpose of minimizing cable voltage drop.

ENGINE CONTROLS
IGNITION SWITCH
When placed in the “ON” position, this switch ener­gizes the fuel solenoid. When placed in the “OFF” position, the flow of fuel to the injection pump is stopped to shut down the engine.
“IDLER” SWITCH
The idler switch has two positions, “HIGH” and “AUTO”.
When in “HIGH” ( ) position, the engine will run continuously at high idle.
When in “AUTO” ( / ) idle position, the idler operates as follows:
a. Welding
When the electrode touches the work, the welding arc is initiated and the engine accelerates to full speed.
After welding ceases (and no auxiliary power is being drawn), the engine will return to low idle after approximately 10 to 14 seconds.
ENGINE PROTECTION SYSTEM
The engine protection system shuts down the engine under high coolant temperature or low engine oil pres­sure conditions by allowing the fuel solenoid valve to close.
AIR INTAKE SHUT-OFF
The air intake shut-off is a automatic/manually device which blocks all intake air from entering the engine.
The automatic feature of the shut-off will engage should excessive over speeding occur. The valve is calibrated at the factory to shutdown within the safety limits of the engine.
To manually shut down the engine, simply pull the emergency stop handle on the lower control panel.
The air intake shut-off device will reset automatically, generally within one minute.
b. Auxiliary Power
With the engine running at low idle and auxiliary power for lights or tools is drawn (approximately 100-150 watts or greater) from the receptacles, the engine will accelerate to high speed. If no power is being drawn from the receptacles ( and not weld­ing) for 10-14 seconds, the idler reduces the engine speed to low idle.
ENGINE TEMPERATURE GAUGE
Displays the coolant temperature in the engine block.
ENGINE OIL PRESSURE GAUGE
Displays the oil pressure to the engine. When the engine starts running, watch for the oil pressure to build up. If no pressure shows within 30 seconds, stop the engine and consult the engine instruction manual.
BATTERY CHARGING AMMETER
Displays the current going from the charging alterna­tor into the batteries. It is normal for charging current to be high (above 15 amps) after starting or when the batteries are ‘low’ on charge.
IMPORTANT: Before restarting engine, verify that the air intake shut-off is in the open position. DO NOT ATTEMPT TO START ENGINE WITH THE AIR INTAKE SHUT-OFF IN THE CLOSED POSITION. This may cause severe damage to the engine.
ENGINE HOUR METER
The engine hour meter records the total running time on the engine in hours. It can be used to keep a record of maintenance on the engine and or welder.

WELDER CONTROLS
POLARITY SWITCH
Turn the Arc Polarity switch to electrode positive or electrode negative as required for each particular application.
CONTROL OF WELDING CURRENT Purpose of Controls
The continuous “Current Control” is the main current adjuster. The “Job Selector” is both a fine current adjuster and the continuous Open Circuit Voltage adjuster. Open Circuit Voltage (OCV) controls the arc characteristics.
“Job Selector”
The “Job Selector” dial is divided into four colored sections providing OCV ranges as follows:
Color Title OCV Range
White Large Electrodes High OCV Black Normal Welding Medium OCV Red Overhead & Vertical Low OCV Grey Special Applications Extra-Low OCV
The “Job Selector” is usually set in the black range because it provides a soft “Buttering “ arc desired for most welding. Some operators prefer to set the “Job Selector” in the red range for a snappy “Digging” arc when welding vertical up or overhead.
“Current Control”
CAUTION
Do not adjust the “Current Control” while welding because this can damage the control.
------------------------------------------------------------------------
The “Current Control” dial is calibrated in amperes on three separate colored dials corresponding to the white, black and red ranges of the “Job Selector” dial. For example: when the “Job Selector” is set on the black range, the approximate welding current is indi­cated on the black scale of the “Current Control” dial.
4. If you want a little more current, turn the “Job Selector” up (counterclockwise) to increase current. If you want a little less current, turn the “Job Selector” down (clockwise) to decrease current.
5. If dialing the desired current with the “Job Selector” moves the setting outside the black range causing undesirable arc characteristics, turn the “Job Selector” back to the center of the black range. Then turn the “Current Control” up or down a little as needed. Readjust the “Job Selector” for the exact characteristics and current desired.
REMOTE CONTROL
A receptacle and “Local/Remote” control switch on the lower front control panel and a remote control box with 100 ft. (30.5 m) of cord for adjusting the OCV at the welding site are standard. Putting the switch in the “REMOTE” position allows fine current control at the remote control box while placing the switch in the “LOCAL” position allows fine current control at the “Job Selector” on the machine.
AUXILIARY POWER CONTROLS
Note: GFCI receptacles are an option and if installed,
see the “MAINTENANCE SECTION” for detailed information on testing and resetting the GFCI receptacle.
115 VAC Receptacle
One 20 amp, 115 VAC duplex receptacle provides 115 VAC for auxiliary power. A total of 26 amps can be drawn from this receptacle.
230 VAC Receptacle
One 15 amp, 230 VAC duplex receptacle provides 230 VAC for auxiliary power. A total of 13 amps can be drawn from this receptacle.
How to Set the Controls
Assume you want a normal soft arc and about 135 amps, using a 5/32” (4.0 mm) electrode:
1. Set the “Job Selector” at the center of the black range.
2. Set the “Current Control” to read 135 amps on the black dial.
3. Start to weld.

2. Turn the “IGNITION” switch to “ON”.
3. Press the Glow Plug button for 15-20 seconds.
4. Press the Glow Plug and the Start button at the same time. When the engine starts running, release both buttons. If the engine fails to start in 60 seconds, wait 30 seconds and repeat the above procedure. Do not allow the starter motor to run continuously for more then 20 seconds.
Note: Extreme cold weather staring may require longer glow plug operation.
STOPPING THE ENGINE
1. Important: Run the engine under low idle for 5 minutes before shutting it off after a full load operation. Note: Failure to do so may lead to turbo charger
trouble.
2. Turn the “IGNITION” switch to “OFF”
At the end of each day’s 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 fuel shut-off valve.
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 person­nel to do this per the instructions in the MAINTE­NANCE section of this manual.

turn 90°.
• Drain oil into a suitable container.
• To close drain valve, turn handle 90° till handle snaps in
the closed position.
• Refill engine with the recommended oil to the appropriate
level. Replace dipstick and tighten the oil filler cap secure­ly.
Change the crankcase oil at regular intervals using the prop­er grade of oil as recommended in the Engine Operating Manual. Wash your hands with soap and water after han­dling used 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.
If the fuel supply 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. See the engine instruction manual.
PERIODIC MAINTENANCE
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. The current control reactor brushes are self-lubricating and should not be greased. Keep the contacts clean. This control should be moved from maximum to mini­mum daily to prevent the controls from sticking.
3. See the engine Instruction Manual for periodic engine maintenance information. Change the oil filter in accor­dance with the instructions in the engine operating man­ual. When the oil filter is changed add one quart of oil to the crankcase to replace the oil held in the filter during operation.
SAE-500™ SEVERE DUTY™
ENGINE AIR FILTER
The engine air filter element is a dry cartridge type. It is located above the engine. It can be cleaned and re­used; however, damaged elements should not be washed or re-used. Remove loose dirt from element with compressed air or water hose directed from inside out. Compressed Air: 100 psi maximum. The fil­ter should never be removed while the engine is run­ning.

MAINTENANCE
BEARING MAINTENANCE
This welder is equipped with a double-shielded ball bearing having sufficient grease to last indefinitely under normal ser­vice. Where the welder is used constantly or in excessively dirty locations, it may be necessary 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.
D-2
To seat the 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. 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%.
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 BRUSH MAINTENANCE
WARNING
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 rotat­ing armature when stoning the commutator.
------------------------------------------------------------------------
The generator brushes are properly adjusted when the welder is shipped. They require no particular attention. DO NOT SHIFT THE BRUSHES or adjust the rocker setting.
Shifting of the 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.
NOTE: If the welder is used in dirty or dusty locations, or if the welder is not used for prolonged periods of time, it may be necessary to clean the commutator and slip rings more often.
Arcing or excessive exciter brush wear indicates a possible misaligned shaft. Have an authorized Field Service Shop check and realign the shaft.
COOLING SYSTEM
The SAE-500™ SEVERE DUTY™ is equipped with a pressure radiator. Keep the radiator cap tight to pre­vent loss of coolant. Clean and flush the cooling sys­tem periodically to prevent clogging the passage and overheating the engine. When antifreeze is needed, always use the permanent type.
WARNING
FUEL FILTERS
When working on the fuel system
• Keep ungrounded lights away, do not smoke !
• Do not spill fuel !
------------------------------------------------------------------------
The SAE-500™ SEVERE DUTY™ is equipped with a Fuel Pre-Filter/Water Separator Assembly is mounted to the engine block just below the oil filter.
The Secondary Fuel Filter is mounted directly to the engine just above the oil filter.
FUEL PRE-FILTER/WATER SEPARATOR ASSEMBLY
The pre-filter is a 30 micron screen designed to pro­tect against gross fuel contamination of the water sep­arator element and the Secondary Fuel Filter.
Replace brushes when they wear within 1/4" 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 experienced 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.

GFCI RECEPTACLE TESTING AND RESET­TING PROCEDURE
The GFCI receptacle should be properly tested at least once every month or whenever it is tripped. To properly test and reset the GFCI receptacle:
• If the receptacle has tripped, first carefully remove any load and check it for damage.
• If the equipment has been shut down, it must be restarted.
• The equipment needs to be operating at high idle speed and any necessary adjustments made on the control panel so that the equipment is providing at least 80 volts to the receptacle input terminals.
• The circuit breaker for this receptacle must not be tripped. Reset if necessary.
• Push the "Reset" button located on the GFCI recep­tacle. This will assure normal GFCI operation.
• Plug a night-light (with an "ON/OFF" switch) or other product (such as a lamp) into the GFCI receptacle and turn the product "ON".
• Push the "Test" button located on the GFCI recepta­cle. The night-light or other product should go "OFF".
• Push the "Reset" button, again. The light or other product should go "ON" again.
If the light or other product remains "ON" when the "Test" button is pushed, the GFCI is not working prop­erly or has been incorrectly installed (miswired). If your GFCI is not working properly, contact a qualified, certified electrician who can assess the situation, rewire the GFCI if necessary or replace the device.
