HIGH ALTITUDE OPERATION
At higher altitudes, output derating may be necessary.
As a rule of thumb, derate the welder output 5% for
every 500 meters (1640 ft.) above 1000 meters (3280
ft.).
FUEL USE DIESEL FUEL ONLY
•Stop engine and allow to cool before
fueling.
•Do not smoke when fueling.
•Fill fuel tank at a moderate rate and
do not overfill.
•Wipe up spilled fuel and allow fumes
to clear before starting engine.
•Keep sparks and flame away from
tank.
------------------------------------------------------------------------
Fill the fuel tank with clean, fresh diesel fuel. The capaci-
ty of the fuel tank is 15 gallons (57 liters). See engine
Operator’s Manual for specific fuel recommendations.
NOTE: Before starting the engine, be sure the fuel shut-
off valve is open.
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 solu-
tion as needed. (See Engine Manual or antifreeze
container for alternate antifreeze recommendation.)
BATTERY CONNECTION
WARNING: Use caution as the electrolyte is a strong
acid that can burn skin and damage eyes.
Remove and discard the insulating caps from the neg-
ative battery terminals. Attach and tighten negative
battery cable terminals.
NOTE: This machine is furnished with wet charged
batteries; if unused for several months, the batteries
may require a booster charge. Be careful to charge
the batteries with the correct polarity. Make sure that
the batteries are level while charging.
Trailer
If the user adapts a trailer, he must assume responsi-
bility that the method of attachment and usage does
not result in a safety hazard nor damage the welding
equipment. 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.
3. Proper placement of the equipment on the trailer to
ensure stability side to side and front to back when
being moved and when standing by itself while being
operated or serviced.
4. Typical conditions of use, i.e., travel speed, rough-
ness of surface on which the trailer will be operated;
environmental conditions, likely maintenance.
5. Conformance with federal, state and local laws. (1)
(1) Consult applicable federal, state and local laws regarding specific
requirements for use on public highways.
ENGINE OIL
The engine is shipped with the engine crankcase filled
with high quality SAE 10W-30 oil (API class CD or bet-
ter). Check the oil level before starting the engine. If it is
not up to the full mark on the dip stick, add oil as
required. Check the oil level every four hours of running
time during the first 35 running hours. Refer to the engine
Operator’s Manual for specific oil recommendations and
break-in information. The oil change interval is dependent
on the quality of the oil and the operating environment.
Refer to the engine Operator’s Manual for the proper ser-
vice and maintenance intervals.
