The AIR VANTAGE® 500 is shipped with the negative battery 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
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 bat- tery may require a booster charge. Be sure to use the correct polarity when charging the battery.
MUFFLER OUTLET PIPE
Remove the plastic plug covering the muffler outlet tube. Using the clamp provided secure the outlet pipe to the outlet tube with the pipe positioned such that it will direct the exhaust in the desired position.
SPARK ARRESTOR
Some federal, state or local laws may require that petrol or diesel engines be equipped with exhaust spark arrestors when they are operated in certain locations where unarrested sparks may present a fire hazard. The standard muffler included with this welder has an internal spark arrestor. When required by local regulations, a suitable spark arrestor, must be installed and properly maintained.
CAUTION
An incorrect arrestor may lead to damage to the engine or adversely affect performance.
AIR CLEANER INLET HOOD
Remove the plastic plug covering the air cleaner inlet. Install the air cleaner inlet hood to the air cleaner.
WELDING TERMINALS
The AIR VANTAGE® 500 is equipped with a toggle switch for selecting "hot" welding terminals when in the "WELD TERMINALS ON" position or "cold" weld- ing terminals when in the "REMOTELY CON- TROLLED" position.
WELDING OUTPUT CABLES
With the engine off, route the electrode and work cables thru the strain relief bracket provided on the front of the base and connect to the terminals provid- ed. These connections should be checked periodically and tightened if necessary.
Listed in Table A.1 are copper cable sizes recom- mended for the rated current and duty cycle. Lengths stipulated are the distance from the welder to work and back to the welder again. Cable sizes are increased for greater lengths primarily for the purpose of minimizing cable voltage drop.

MACHINE GROUNDING
Because this portable engine driven welder creates its own power, it is not necessary to connect its frame to an earth ground, unless the machine is connected to premises wiring (home, shop, etc.).
To prevent dangerous electric shock, other equipment to which this engine driven welder supplies power must:
WARNING
•Be grounded to the frame of the welder using a grounded type plug or be double insulated.
•Do not ground the machine to a pipe that carries explosive or combustible material.
When this welder is mounted on a truck or trailer, its frame must be securely connected to the metal frame of the vehicle. When this engine driven welder is con- nected to premises wiring such as that in a home or shop, its frame must be connected to the system earth ground. See further connection instructions in the sec- tion entitled “Standby Power Connections” as well as the article on grounding in the latest National Electrical Code and the local codes.
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 ground stake going into the ground for at least 10 Feet or to the metal frame- work of a building which has been effectively ground- ed.
The National Electric 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.
