recommends that the following procedure be
used for routine shutdowns in order to keep
the system in optimal condition, and
minimimize undue stress that may occur at
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,
hydraulic pump, 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
Welder
,
Generator
,
Hydraulic Pump
and
Compressor
switches on the control panel to their
OFF
positions.
5. Allow machine to run at idle for 3-5
minutes to allow for a cool down
sequence.
6. Turn the
Crane Remote switch
, or
master power switch
, or
Engine
Control Switch
to the
OFF
position.
