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
1
]. If no air
leaks are present, the engine
should start at idle speed the next
time it is started.
4.3 ENGINE THROTTLE
CONTROL FUNCTIONS
The engine speed is controlled by three
factors:
1. The level of air pressure in the tank
and the position of the pilot valve
adjustment switch (refer to
Figure
4-3
).
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.
Consult Table 4A: Engine Throttle Control
Function
Conditions
to understand how the
engine speed relates to the demand(s) of the
machine system’s output functions.
NOTE
Refer to Engine Owner’s Manual for
additional information pertaining to the
starting of the engine.
