Operation
Warning and Fault Indicators
A fault condition may trigger a popup dialog
box on the display describing the nature of
the fault during operation. Corresponding
red or amber warning lights will illuminate to
indicate the severity of the fault. If an Engine
Shutdown fault condition is present, stop the forklift, follow
proper shut down procedures, tag the forklift with "Do
Not Operate" tags, and have a qualified mechanic service
or repair the forklift BEFORE placing it into service again.
Report all warning indicators and fault codes to a qualified
mechanic. Ignoring warning indicators or fault codes can
cause improper performance, which could result in death,
serious injury, or property damage.
Fault condition dialog boxes may pop up and warning lights
on the display will illuminate during critical circumstances.
Some of these conditions demand immediate attention and
forklift servicing. If an Engine Shutdown fault condition is
present, the forklift should be shut down as soon as practical
to prevent serious mechanical failure.
Some of the following indicators are green while the engine
is within normal operation range, turning yellow when the
normal operating range is exceeded. Some of these indicators
turn red and become warnings when a particular parameter
reaches or exceeds a critical level.
