PRE-OPERATION INSTALLATION
Exhaust Spark Arrester
Some federal, state or local laws may require that
engines be equipped with exhaust spark arresters
when they are operated in certain locations where
unarrested sparks may present a fire hazard. The
standard mufflers included with these welders do not
qualify as spark arresters. When required by local
regulations, suitable spark arresters must be installed
and properly maintained.
Use of an incorrect arrester may lead to engine damage
or performance loss. Contact the engine manufacturer
for specific recommendations.
------------------------------------------------------------------------
Location / Ventilation
Always operate the welder with the doors closed.
Leaving the doors open changes the designed air flow
and may cause overheating.
The welder should be located to provide an unrestrict-
ed flow of clean, cool air. Also, locate the welder so
that engine exhaust fumes are properly vented to an
outside area.
STACKING
Classic III and III D machines cannot be stacked.
ANGLE OF OPERATION
To achieve optimum engine performance the Classic
III and III D should be run in a level position. The max-
imum angle of operation for the TM27 and TMD27
engines is 60 degrees in a direction to cause the air
intake manifold to be angled up, 45 degrees for the air
intake manifold to be angled down, and 50 degrees
for the welder control panel to be angled up or down.
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
crankcase. When operating the welder at an angle,
the effective fuel capacity will be less than the speci-
fied 15 gallons (57 Ltrs.).
Machine Grounding
According to the United States National Electrical
Code, the frame of this portable generator is not
required to be grounded and is permitted to serve as
the grounding means for cord connected equipment
plugged into its receptacle.
Some state, local, or other codes or unusual operating
circumstances may require the machine frame to be
grounded. It is recommended that you determine the
extent to which such requirements may apply to your
particular situation and follow them explicitly. A
machine grounding stud marked with the symbol is
provided on the welding generator frame foot. (If an
older portable welder does not have a grounding stud,
connect the ground wire to an unpainted frame screw
or bolt.) 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 Code lists a number of alternate means
of grounding electrical equipment.
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.
