Vanair Manufacturing, 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
