4.1 GENERAL INFORMATION
The Air N Arc
I
-300 All-In-One Power
System has a comprehensive array of
controls and indicators for each function of
the power system. Understanding the correct
operational functions of the
I
-300 Series
system will allow the operator to recognize
various operational conditions, such as when
the machine is functioning optimally, when
maintenance is needed, or if there are
indications of a malfunction. The information
in the Operation Section will help the
operator to recognize, distinguish and
interpret these symptoms.
WARNING
Before starting, performing maintenance,
or replacing parts, relieve the entire
system pressure by opening the air tank
drain/vent valve, which will vent all
pressure to the atmosphere.
Refer to
Figure 4-1
. Open the
compressor fill cap SLOWLY (contents
under pressure) to make sure all
pressure has been relieved.
CAUTION
Compressors and engines generate heat
and create hot surfaces. Use caution
when operating and servicing
equipment. Some surfaces and
components may be hot.
IMPORTANT
Do not operate machine without
hydraulic connections and proper
amounts of fluid. Danger to pump will
occur.
DANGER
DO NOT weld with the electrode holder
connected to the negative (-) port and the
work piece connected to the vehicle.
Bodily harm and equipment damage may
occur.
