The Above For Gasoline Engines

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 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 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.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.

___________________________________________________

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.

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.

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.

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.c. 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.d. 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.

WELDING 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.

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.

6.h. Also see item 1.c.

Remember that welding sparks and hot

though

they have

Preparation

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
1235 Jefferson Davis Highway, Arlington, VA 22202.

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.

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.

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.

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.

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.

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
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.

INSTALLATION INSTRUCTIONS

Safety Precautions

WARNING

Do not attempt to use this equipment until you
have thoroughly read the engine manufacturer’s
manual supplied with your welder. It includes
important safety precautions, detailed engine
starting, operating and maintenance instructions,
and parts lists.

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

ELECTRIC SHOCK can kill.

• Do not touch electrically live parts or
electrode with skin or wet clothing.

• Insulate yourself from work and
ground

• Always wear dry insulating gloves.

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

ENGINE EXHAUST can kill.

• Use in open, well ventilated areas or
vent exhaust outside.

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

MOVING PARTS can injure.

• Do not operate with doors open or
guards off.

• Stop engine before servicing.

• Keep away from moving parts.

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

See additional warning information at

front of this operator’s manual.

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

When this welder is mounted on a truck or trailer, it’s
frame must be securely connected to the metal frame
of the vehicle.

Where this engine driven welder is connected to
premises wiring such as that in your home or shop, it’s
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 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 front of the welder.

Spark Arrester

Some federal, state, or local laws may require that
gasoline 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, the K894-1 spark arrester must be
installed and properly maintained.

Machine Grounding

Because this portable engine driven welder or genera­tor creates it’s own power, it is not necessary to con­nect it’s frame to an earth ground, unless the machine
is connected to premises wiring (your home, shop,
etc.).

To prevent dangerous electric shock, other equipment
to which this engine driven welder supplies power
must:

• be grounded to the frame of the welder using a

grounded type plug, or

• be double insulated.

WELDMARK 225

CAUTION

An incorrect arrester may lead to damage to the
engine or adversely affect performance.

Trailers

The recommended trailer for use with this equipment
for in plant and yard towing by a vehicle is Lincoln’s
K768-2. Consult applicable federal, state, and local
laws regarding specific requirements for use on public
highways.

If the user adapts a non-Lincoln trailer, he must
assume responsibility that the method of attachment
and usage does not result in a safety hazard nor dam­age the welding equipment.

A-4

Some of the factors to be considered are as follows:

1. Design capacity of trailer vs. weight of 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.

Location / Ventilation

A-5

Internal combustion engines are designed to run in a
level condition which is where the optimum perfor­mance is achieved. The maximum angle of operation
for the engine is 15 degrees from horizontal in any
direction. If the engine is to be operated at an angle,
provisions must be made for checking and maintain­ing the oil at the normal (FULL) oil capacity in the
crankcase in a level condition.

When operating at an angle, the effective fuel capaci­ty will be slightly less than the specified 10 gallons.

High Altitude Operation

If the Weldmark 225 will be consistently operated at
altitudes above 5000 ft, a carburetor jet designed for
high altitudes should be installed. This will result in
better fuel economy, cleaner exhaust, and longer
spark plug life. It will not

CAUTION

Do not operate a Weldmark 225 with a high alti­tude jet installed at altitudes below 5000 ft. This
will result in the engine running too lean and
result in higher engine operating temperatures
which can shorten engine life.

High altitude jet kits are available from the engine
manufacturer. For the Kohler model order kit part no.

The welder should be located to provide an unrestrict­ed flow of clean, cool air to the cooling air inlets and to
avoid heated air coming out of the welder recirculating
back to the cooling air inlet. Also, locate the welder so
that engine exhaust fumes are properly vented to an
outside area.

Motor Starting

Most 1.5 hp AC single phase motors can be started if
there is no load on the motor or other load connected
to the machine, since the full load current rating of a

1.5 hp motor is approximately 20 amperes (10

amperes for 230 volt motors). The motor may be run
at full load when plugged into only one side of the
duplex receptacle. Larger motors through 2 hp can be
run provided the receptacle rating as previously stated
is not exceeded. This may necessitate 230V operation
only.

The current rating of any plug used with the system
must be at least equal to the current load through the
associated receptacle (Refer to Tables I and II). Do not
attempt to connect power receptacles in parallel.

WELDMARK 225

• 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.

• 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.

WARNING

• Do not touch electrically live parts
of electrode with skin or wet
clothing.

• Keep flammable material away.

• Insulate yourself from work and

ground. Wear eye, ear, and body
protection.

• Keep your head out of the fumes.

• Use ventilation or exhaust to

remove fumes from breathing zone.

Be sure all Pre-Operation Maintenance has been per­formed. Also, read the Engine Owner’s Manual.

Remove all loads connected to the AC power recepta­cles. To start the engine, set the “Idler Control” switch
in the Automatic ( / ) position.

Use the choke control as follows:

Stopping the Engine

Remove all welding and auxiliary power loads and
allow engine to run at low idle speed for a few minutes
to cool the engine.

Stop the engine by placing the “Engine” switch in the
“OFF” position.

A fuel shut off valve is not required on the WELD­MARK 225 because the fuel tank is mounted below
the engine.

Break-in Period

It is normal for any engine to use a greater amount of
oil until the break-in is accomplished. Check the oil
level twice a day during the break-in period (approxi­mately 50 running hours)).

IMPORTANT: IN ORDER TO ACCOMPLISH THIS

BREAK-IN, THE UNIT SHOULD BE
SUBJECTED TO MODERATE
LOADS, WITHIN THE RATING OF
THE MACHINE. AVOID LONG IDLE
RUNNING PERIODS. REMOVE
LOADS AND ALLOW ENGINE TO
COOL BEFORE SHUTDOWN.

The engine manufacturer’s recommendation for the
running time until the first oil change is ( 5 ) HRS:

Kohler Engine - Always pull the choke control out
when starting the engine; cold, warm or hot. Place the
“Engine” switch in the “ON” position.

Push the “START” button and crank the engine until it
starts. Release the button as soon as the engine
starts. Do not push the “START” button while the
engine is running because this will cause damage to
the ring gear and/or starter motor. After the engine
has started, slowly return the choke control to the full
“in” position (choke open).

After running at high engine speed for 10-14 seconds,
the engine will go to low idle.

Allow the engine to warm up by letting it run at low idle
for a few minutes.

WELDMARK 225

The oil filter is to be changed at the second oil
change. Refer to the Engine Owner’s Manual for more
information.

OPERATION

Welding Process

Stick (Constant Current) Welding

Connect welding cables to the "TO WORK” and
"ELECTRODE” studs. Start the engine. Set the
"Polarity” switch to the desired polarity. Set the
“RANGE” switch to a setting that is equal to or slightly
greater than the desired welding current. (The
“RANGE” dial marking indicates the maximum
for that range). Fine adjustment of the welding current
is made by adjusting the output “CONTROL” or
remote control. For best arc stability, use settings

5 through 10.

The Weldmark 225 can be used with a broad range of
AC and DC stick electrodes. See “Welding Tips 1”
included with the WELDMARK 225 for electrodes
within the rating of this unit and recommended weld­ing currents of each.

TIG (Constant Current) Welding

The K930-[ ] TIG Module installed on a Weldmark 225
provides high frequency and shielding gas control for
AC and DC GTAW (TIG) welding processes. The TIG
Module allows full range output control. Afterflow time
is adjustable from 0 to 55 seconds.

SAFETY PRECAUTIONS

WARNING

Have qualified personnel do the maintenance
work. Turn the engine off before working inside
the machine. 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.

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 Field Service Shop.

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

ELECTRIC SHOCK can kill.

• Do not touch electrically live parts or

electrode with skin or wet clothing.

• Insulate yourself from work and

ground

• Always wear dry insulating gloves.

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

ENGINE EXHAUST can kill.

• Use in open, well ventilated areas or

vent exhaust outside.

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

MOVING PARTS can injure.

• Do not operate with doors open or

guards off.

• Stop engine before servicing.

• Keep away from moving parts.

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

See additional warning information

throughout this operator’s manual and
the Engine manual as well.

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

Read the Safety Precautions in the front of this manual
and the engine instruction manual before working on
this machine.

Keep all equipment safety guards, covers, and devices
in position and in good repair. Keep hands, hair, cloth­ing, and tools away from gears, fans, and all other
moving parts when starting, operating, or repairing the
equipment.

CAUTION

Make certain that the oil filler cap is securely tight­ened after checking or adding oil. If the cap is not
tight, oil consumption can increase significantly
which may be evidenced by white smoke coming
from the exhaust.

• OIL - Maintenance schedule for changing the oil and
oil filter after break-in:

• Oil - 100 HRS

• Oil Filter - 200 HRS

The above schedule is for normal operating condi­tions. More frequent oil changes are required with
dusty, high temperature and other severe operating
conditions. Refer to the maintenance section of the
Engine Owner's Manual for more information.

NOTE: Engine life will be reduced if the oil and oil
filter are not changed according to the manufacturer’s
recommendation.

• Air Cleaner - With normal operating conditions, the

maintenance schedule for cleaning and re-oiling
the foam pre-filter is every 25 hours and replace­ment of the air cleaner filter every 100 hours.
More frequent servicing is required with dusty
operating conditions. Refer to the maintenance
section of the Engine Owner’s Manual for more
information.

• Refer to the maintenance section of the Engine

Owner’s Manual for the maintenance schedule,
spark plug servicing, cooling system servicing, and
fuel filter replacement.

• Blow out the machine with low pressure air period-

ically. In particularly dirty locations, this may be
required once a week.

• Output Selector and Polarity Switch contacts

should not be greased. To keep contacts clean,
rotate the switch through its entire range frequently.
A good practice is to turn the handle from maximum
to minimum setting twice each morning before
starting to weld.

Routine Maintenance

• At the end of each day’s use, refill the fuel tank to
minimize moisture condensation in the tank.
Running out of fuel tends to draw dirt into the fuel
system. Also, check the crankcase oil level and
add oil if indicated.

Engine Adjustments

OVERSPEED IS HAZARDOUS

WARNING

The maximum allowable high idle speed for this
machine is 3750 RPM, no load. Do NOT tamper
with governor components or setting or make any
other adjustments to increase the maximum
speed. Severe personal injury and damage to the
machine can result if operated at speeds above
maximum.

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

Adjustments to the engine are to be made only by an
authorized Field Service Shop.

Slip Rings

A slight amount of darkening and wear of the slip rings
and brushes is normal. Brushes should be inspected
when a general overhaul is necessary. If brushes are
to be replaced, clean slip rings with a fine emery
paper.

WARNING

GASES FROM BATTERY can explode.

• Keep sparks, flame and cigarettes away from battery.

To prevent EXPLOSION when:

• INSTALLING A NEW BATTERY - disconnect negative
cable from old battery first and connect to new battery
last.

• CONNECTING A BATTERY CHARGER - Remove bat­tery from welder by disconnecting negative cable first,
then positive cable and battery clamp. When rein­stalling, connect negative cable last. Keep well venti­lated.

• USING A BOOSTER - connect positive lead to battery
first then connect negative lead to engine foot.

BATTERY ACID CAN BURN EYES AND SKIN.

• Wear gloves and eye protection and be careful when
working near battery. Follow instructions printed on
battery.

Battery

1. When replacing, jumping, or otherwise connecting
the battery to the battery cables, the proper
polarity must be observed. Failure to observe
the proper polarity could result in damage to the
charging circuit. The positive (+) battery cable
has a red terminal cover.

CAUTION

Do not attempt to polish slip rings while engine is
running.
