WARNING
Mar ‘95
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.

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.
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.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.
5.e. Also see item 1.b.
Mar ‘95
FOR ELECTRICALLY
powered equipment.
8.a. Turn off input power using the disconnect
switch at the fuse box before working on

8.b. Install equipment in accordance with the U.S. National
Electrical Code, all local codes and the manufacturer’s
recommendations.
8.c. Ground the equipment in accordance with the U.S. National
Electrical Code and the manufacturer’s recommendations.
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.

SAFETY
iii
Mar ‘95
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.
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.

PRÉCAUTIONS DE SÛRETÉ
Pour
votre propre protection lire et observer toutes les instruc-
tions 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 soud-
er 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 pro-
téger 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-inflamma-
bles.
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.
6. Eloigner les matériaux inflammables ou les recouvrir afin de
prévenir tout risque d’incendie dû aux étincelles.
7. Quand on ne soud
e 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 lev-
age, 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 forte-
ment 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 l’électricité et aux recommendations du fabricant. Le dis-
positif 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.

STACKING
POWER-ARC 4000 machines CANNOT be stacked.
TILTING
Place the machine on a secure, level surface whenev-
er you use it or store it. Any surfaces you place it on
other than the ground must be firm, non-skid, and
structurally sound.
The gasoline engine is designed to run in a level posi-
tion for best performance. It can operate at an angle,
but this should never be more than 15 degrees in any
direction. If you do operate it at a slight angle, be
sure to check the oil regularly and keep the oil level
full. Also, fuel capacity will be a little less at an angle.
LIFTING
The POWER-ARC 4000 should be lifted by two peo-
ple. (It weighs 160 lbs/72.5 kg.) Its welded tube roll
cage is designed to make lifting easy.
ANGLE OF OPERATION
Internal combustion engines are designed to run in a
level condition to achieve optimum performance. The
maximum angle of operation for the engine is 15
degrees from horizontal in any direction. Be certain
to place the machine on a firm, non-skid, structural
supporting surface. Anchor unit if necessary.
If you are operating the engine at a slight angle, be
certain to check the oil regularly and maintain a level,
full oil condition. The effective fuel capacity will also
be slightly less than the specified 1.00 gallon (3.8
liters).
PRE-OPERATION ENGINE SERVICE
Read and understand the information about the gaso-
line engine in the OPERATION and MAINTENANCE
sections of this manual and the engine owner’s man-
ual before you operate the POWER-ARC 4000.
• Keep hands away from the engine muffler or
HOT engine parts.
• Stop the engine when fueling.
• Do not smoke when fueling.
• Remove the fuel cap slowly to release pressure.
• Do not overfill the fuel tank.
• Wipe up spilled fuel and allow the fumes to clear
before starting the engine.
• Keep sparks and flame away from the fuel tank.
OIL
The Power-Arc 4000 with the Briggs and Stratton 8
HP engine produced after August 1998 and the
Power-Arc 4000 with the Honda 9 HP engine are sup-
plied with low oil shutdown protection. The Power-
Arc 4000 with the Briggs and Stratton 8 HP engine
produced before August 1998 is NOT equipped with
an "Oil Gard"® low oil shutdown protection device.
Oil must be regularly checked and added as needed.
However, the engine block is equipped to accept an
"Oil Gard"® accessory kit available from authorized
Briggs and Stratton Distributors. An installed kit will
sense low oil levels and will automatically shut down
the engine. The engine cannot be restarted until suffi-
cient oil is added.
The POWER-ARC 4000 is shipped with the engine
filled with SAE 10W-30 oil. CHECK THE OIL LEVEL
BEFORE YOU START THE ENGINE. This is an
added precaution. When full, the oil level should be
at the top of the fill plug hole. If it is not full, add
enough oil to fill it. Be sure the fill plug is tight.
Change oil after the first 5 hours of operation.
For more oil fill and service information, see the
Engine owner’s manual.
FUEL
Fill the fuel tank with clean, fresh, regular
grade lead-free gasoline. DO NOT MIX

engine if your needs so require.
To install the deflector, do the following:
• Align the holes on the deflector plate with the holes
on the muffler.
•
Position the deflector so that the opening points either
right, left, or downward, away from the operator.
Never position the deflector upward. Moisture or
debris can enter the engine and damage it. As a
general safety practice, position the deflector to
direct exhaust gases away from the operator’s
face and eyes.
• Fasten the deflector onto the muffler with the
screws provided.
NOTE: The deflector reduces generator output
power up to 100 watts.
SPARK ARRESTER
Gasoline engine mufflers may emit sparks when the
engine is running. Some federal, state, or local laws
require spark arresters in locations where unarrested
sparks could present a fire hazard.
Standard mufflers and deflectors (like the ones
included with the POWER-ARC 4000 Briggs &
Stratton engines) do not act as spark arresters. When
local laws require it, a spark arrester must be installed
on the machine and properly maintained
.
An optional spark arrester kit is available for your
POWER-ARC 4000 Briggs & Stratton 8 HP Kool-Bore
engine. See the ACCESSORIES section of this man-
ual for more information.
An incorrect spark arrester may lead to damage to
the engine or reduce performance. A suitable
spark arrester for the Briggs & Stratton 8 HP Kool
Bore
®
engine is available as a Lincoln field-
installed option.
A spark arrester is available for your POWER-ARC
4000 Briggs & Stratton 9 HP Vanguard engine from
your local Briggs & Stratton engine dealer.
The Power-Arc 4000 with the Honda engine comes
with a spark arrester as standard equipment. Refer to
the engine owner’s manual for proper maintenance.

Cable Installation
Install the welding cables to your POWER-ARC 4000
as follows. See Figure A.1 for the location of parts.
1. The gasoline engine must be OFF to install weld-
ing cables.
2. Remove the 1/2 - 13 flanged nuts from the output
terminals.
3. Connect the electrode holder and work cables to
the weld output terminals. You can connect
either cable to either terminal, since the POWER-
ARC 4000 provides AC weld current.
4. Tighten the flanged nuts securely.
5. Be certain that the metal piece you are welding
(the “work”) is securely connected to the work
clamp and cable.
6. Check and tighten the connections periodically.
• Loose connections will cause the output termi-
nals to overheat. The terminals may eventually
melt.
• Do not cross the welding cables at the output
terminal connection. Keep the cables isolated
and separate from one another.
Lincoln Electric offers a welding accessory kit with
the properly specified welding cables. See the
ACCESSORIES section of this manual for more infor-
mation.
MACHINE GROUNDING
Because the POWER-ARC 4000 creates
its own power from its gasoline-engine
driven generator, you do not need to
connect the machine frame to an earth
ground. However, for best protection
against electrical shock, connect a heavy gauge wire
from the ground stud located on the bottom center of
the output panel (see Figure A.1) to a suitable earth
ground such as a metal pipe driven into the ground.
Do not ground the machine to a pipe that carries
explosive or combustible material.
When the POWER-ARC 4000 is mounted
on a truck or a trailer, the machine gen-
erator ground stud MUST be securely
connected to the metal frame of the
vehicle. See Figure A.1. The ground
stud is marked with the symbol.
PLUGS AND HAND-HELD EQUIPMENT
For further protection against electric shock, any
electrical equipment connected to the generator
receptacles must use a three-blade, grounded type
plug or an Underwriter’s Laboratories (UL) approved
double insulation system with a two-blade plug.
Lincoln offers an accessory plug kit that has the right
type of plugs. See the ACCESSORIES section of this
manual for details.
Ground fault protection is needed for hand held
equipment.
Never operate this machine with damaged or defec-
tive cords. All electrical equipment must be in safe
condition.
AUXILIARY POWER RECEPTACLES
The control panel of the POWER-ARC 4000 features
two auxiliary power receptacles:
• A 20 amp, 120 volt duplex (double outlet) recepta-
cle
• A 20 amp 240 volt simplex (single outlet) recepta-
cle.
See Figure A.1.
Through these receptacles the machine can supply
up to 4,000 rated continuous watts and 4,400 surge
watts of single-phase AC power.

PREMISES WIRING
The POWER-ARC 4000 three-wire, grounded neutral
generator allows it to be connected to premises
wiring. However, the wiring procedure needed to
meet the National Electric Code (NEC) regulations as
well as city ordinances and can be confusing. The
connections could vary from a "commonly grounded"
to a "separately derived" system depending on
whether you want the unit to be "hard wired" or tem-
porary to the premises.
Only a licensed, certified, trained electrician
should install the machine to a premises or resi-
dential electrical system. Be certain that:
• The premises is isolated and no feed backing
into the utility system can occur. Certain state
and local laws require the premises to be isolat-
ed before the generator is linked to the premis-
es. Check your state and local requirements.
• A double pole, double throw transfer switch in
conjunction with the properly rated double
throw circuit breaker is connected between the
generator power and the utility meter.
The POWER-ARC 4000 does not have a combined
120/240 volt twist-lock receptacle and cannot be
connected to a premises as described in other
Lincoln literature.
Remember that the POWER-ARC 4000 is intended
only for backup, intermittent use power. Oil level must
be checked after every 5 hours of use. The Briggs &
Stratton engines used on the Power-Arc 4000 before
August 1998 did not include a low oil shutdown
option as standard equipment. It cannot withstand
long-term use without proper maintenance. See the
MAINTENANCE section of this manual and the
engine owner’s manual for more information.
Certain electrical devices cannot be powered by the
POWER-ARC 4000. Refer to Table A.2 for these
devices.
CIRCUIT BREAKERS
The POWER-ARC 4000 has its own 20 amp circuit
breakers for overload protection. When the machine
is operated in high temperature environments, the
breakers may tend to trip at lower loads than normal-
ly.
Never bypass the circuit breakers. Without over-
load protection, the power-arc 4000 could over-
heat and/or cause damage to the equipment being
used.

RECOMMENDED APPLICATIONS
GENERATOR
The POWER-ARC 4000 gives AC generator output for
medium use, non-commercial demands. For more
details on operating the generator, see GENERATOR
OPERATION in the OPERATION section of this manu-
al.
WELDER
The POWER-ARC 4000 provides excellent constant
current AC welding output for stick (SMAW) welding.
For more details on using the machine as a welder,
see WELDING OPERATION in the OPERATION sec-
tion of this manual.
OPERATIONAL FEATURES AND
CONTROLS
The POWER-ARC 4000 was designed for simplicity.
Therefore, it has very few operating controls. A single
dial on the control panel lets you select either genera-
tor or welding use. For welding, the same dial selects
continuous current output over the machine’s 70 to
125 amp range.
The gasoline engine controls include a recoil starter,
choke, and rotary stop switch. See ENGINE OPERA-
TION in the OPERATION section of this manual and
the engine owner’s manual for details about starting,
running, stopping, and breaking in the gasoline
engine.

Gard® kit is available from Briggs & Stratton.
WELDING CAPABILITY
The POWER-ARC 4000 is rated 125 amps, 20 volts at
30% duty cycle on a ten-minute basis. This means
that you can load the welder to 125 amps for three
minutes out of every ten-minute period. The machine
is also capable of higher duty cycles at lower output
currents. You can load the welder to 100 amps for six
minutes out of ten for a 60% duty cycle.
The current is continuously variable from 70 to 125
amps AC. The POWER-ARC 4000 can weld with all
3/32 and most 1/8 inch diameter Lincoln AC elec-
trodes.
LIMITATIONS
• The POWER-ARC 4000 is not recommended for
any processes besides those that are normally per-
formed using stick welding (SMAW) procedures.
• The POWER-ARC 4000 is not recommended for
pipe thawing.
• During welding, generator power is limited to 100
watts, and output voltages can drop from 120 to 80
volts and 240 to 160 volts. Therefore, DO NOT
OPERATE ANY SENSITIVE ELECTRICAL EQUIP-
MENT WHILE YOU ARE WELDING.

ENGINE OPERATION
DO NOT RUN THE ENGINE AT EXCESSIVE
SPEEDS. The maximum allowable high idle speed
for the POWER-ARC 4000 is 3750 RPM, no load.
Do NOT adjust the governor screw on the engine.
Severe personal injury and damage to the
machine can result if it is operated at speeds
above the maximum rated speed.
Read and understand all safety instructions included
in the engine manufacturer’s Operating and
Maintenance Instructions manual that is shipped
with the POWER-ARC 4000.
BEFORE STARTING THE ENGINE
CHECK AND FILL THE ENGINE OIL LEVEL:
1. Place the machine on a level
surface.
2. Open the oil fill plug.
3. Fill (if necessary) until oil flows out the top of the
fill plug hole.
4. Replace the fill plug and tighten securely.
CHECK AND FILL THE ENGINE FUEL TANK:
1. Remove the fuel tank cap.
2. Fill the tank to allow approximately
1/4 inch (5 mm) of tank space for fuel
expansion. DO NOT FILL THE TANK
TO THE POINT OF OVERFLOW.
3. Replace the fuel tank cap and tighten securely.
NOTE: The engine will operate satisfactorily on any
gasoline meant for automotive use. A mini-
mum of 87 octane is recommended. DO NOT
MIX OIL WITH THE GASOLINE.
Use clean, fresh, lead-free gasoline. Leaded gasoline
may be used if lead-free is not available. However,
lead-free gasoline leaves fewer combustion deposits
and gives longer valve life. Purchase gasoline in
quantities that will be used within 30 days, to assure
freshness.
NOTE: We DO NOT recommend using gasoline that
contains alcohol, such as gasohol. However,
if gasoline with alcohol is used, it MUST NOT
contain more than 10% Ethanol and MUST
be removed from the engine during storage.
DO NOT use gasoline containing Methanol.
STARTING THE ENGINE
NOTE: Remove all loads connected to the AC power
receptacles before starting the gasoline
engine. Turn the Rotary Stop Switch to the
“ON” position.
FOR A “COLD” ENGINE:
1. Open the fuel shutoff valve.
2. Place the choke lever in the “CHOKE”
position.
3. Pull slightly on the recoil starter handle until resis-
tance is felt.
