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, wetstacking (oil or tar like sub-
stance 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 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 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 suit-
able resistive load bank. Note that any
attempt to short the output studs by con-
necting 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 gener-
ator and voids the warranty.
2. Set the welder controls for an output cur-
rent 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 Deutz engine is air cooled by a belt driven axial
blower. The oil cooler and engine cooling fins should
be blown out with compressed air or steam to main-
tain proper cooling (See the engine Owners Manual
for procedures and frequency).
INSTALLATION
BATTERY CONNECTION
• 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 nega-
tive battery lead at engine foot.
IMPORTANT: To prevent ELECTRICAL DAMAGE
WHEN:
a) Installing new batteries.
b) Using a booster.
Use correct polarity — Negative Ground.
------------------------------------------------------------------------
The BIG RED™ 500 is shipped with the negative bat-
tery cable disconnected. Before you operate the
machine, make sure the Engine Switch is in the OFF
position and attach the disconnected cable securely to
the negative (-) battery terminal.
Remove the insulating cap from the negative battery
terminal. Replace and tighten negative battery cable
terminal.
NOTE: This machine is furnished with a wet charged
battery; if unused for several months, the battery may
require a booster charge. Be sure to use the correct
polarity when charging the battery.
BIG RED™ 500
WARNING
GASES FROM BATTERY can explode.
• Keep sparks, flame and cigarettes
away from battery.
To prevent EXPLOSION when:
BATTERY ACID can burn eyes and skin.
• Wear gloves and eye protection and
be careful when working near battery.
• Follow instructions printed on battery.
