Engine Throttle Control Functions - Vanair ALL-IN-ONE POWER SYSTEM AIR N ARC 150 Series Operations Manual & Parts List

SECTION 4: OPERATION
Vanair Mfg., Inc. recommends that the
following procedure is used for routine
shutdowns in order to keep the system in
optimal condition, and minimimize undue
stress that may occur during the next start up
session if some of the machine conditions
were left in working mode(s) or had auxiliary
power draws left intact (such as a tool
receptacle left plugged into the generator,
etc.).
To prepare the machine for shutdown:
1. Shut off any tools or other items that
are drawing power from the
generator, or compressed air from
the air tank.
2. Close all service valves.
3. Unplug any power cords that are
plugged into the generator panel.
4. Turn the Generator and Welder
switches on the control panel
(Figure 4-2, [B & G]) to their OFF
positions.
5. Allow machine to run at idle for a 3-
5 minutes to allow for a cool down
sequence.
6. Turn the Engine Control Switch to
the OFF position [A

and the position of the pilot valve
adjustment switch (refer to Figure
4-4).
2. The position of the welder switch on
the unit control panel, and the use
of the welder.
3. The position of the generator switch
on the control panel.
