Operation
service or repair the Telehandler 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 will pop up and warning lights
on the display will illuminate during critical circumstances.
Some of these conditions demand immediate attention and
Telehandler servicing. If an Engine Shutdown fault condition
is present, the Telehandler should be shut down as soon as
practical to prevent serious mechanical failure. For more
information refer to “Display Indicators” section.
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.
Battery Voltage Indicator; yellow between 11.5
V and12.5 V. Indicator turns RED warning below
11.5V. The normal operating range is 12.6-14V.
Coolant Temperature Indicator; it is yellow between
205 and 2150F. It becomes a RED warning above
2160F. Normal operating range: 180 to 2050F.
Fuel Level Indicator, between 10 and 20% fuel left
in the tank. It becomes a RED warning below 10%.
High Hydraulic Temperature Indicator
Low Brake Pressure Warning
Low Oil Pressure Indicator, between 10 and 20 psi.
Engine must be running above 500 RPM.
It turns into
a RED Low Oil Pressure Warning, below 10 psi.
Rear Axle Centered
Rear Axle Locked
Service Reminder; will be displayed in RED when a
maintenance interval has been exceeded.
Transmission Temperature Indicator, between 215
and 224 0F. It becomes a RED Warning, above 225 0F.
Wait To Start Indicator, displayed when the key
switch is moved to the RUN position. Wait until the
indicator goes out before starting the engine.
Water In Fuel Indicator will be displayed when wa-
ter is detected in the fuel filter. Drain the water by
opening the petcock on the bottom of fuel filter.
The Low Coolant Level Indicator will be displayed
when the coolant level in the surge tank drops
below normal. Add coolant to the top of the sight
gauge of the surge tank.
The Check Engine Indicator displayed by itself shows
the engine is operating normally but there are one
or more minor faults with the engine electronic
management system.
The Check Engine Indicator displayed with a steady Engine
Shutdown Indicator shows there are one or more severe faults
with the engine electronic management system and the
engine is operating at reduce power.
The Check Engine Indicator displayed with a flashing Engine
Shutdown Indicator shows there are one or more very severe
faults with the engine electronic management system and the
engine should be shut down as soon as possible (the engine
may automatically shutdown in some conditions).
The Check Engine Indicator displayed with a flashing Low
DEF Level Indicator shows the DEF tank is critically low and
the engine is operating at reduced power; add DEF as soon as
possible.
The Check Engine Indicator displayed with a steady Engine
Shutdown Indicator and a flashing Low DEF Level Indicator
shows the DEF tank is empty and the engine is operating at
reduced power or limited to idle; add DEF immediately.
The Check Engine Indicator displayed with the Exhaust
System Cleaning Indicator shows that a manual regeneration
of the exhaust system is required and the engine is operating
at reduced power.
A steady Engine Shutdown Indicator displayed with
the Check Engine Indicator shows there are one
or more severe faults with the engine electronic
management system and the engine is operating at
reduce power.
A flashing Engine Shutdown Indicator displayed with the
Check Engine Indicator shows there are one or more very
severe shows there are one or more very severe faults with
the engine electronic management system and the engine
should be shut down as soon as possible (the engine may
automatically shutdown in some conditions).
A steady Engine Shutdown Indicator displayed with the Check
Engine Indicator and a flashing Low DEF Level Indicator shows
the DEF tank is empty and the engine power is operating at
reduced power or limited to idle; add DEF immediately.
EXHAUST AFTER TREATMENT SYSTEM INDICATORS
The engine control system monitors and manages the
exhaust after treatment system. The system works to reduce
soot loading. If excessive soot loading is detected, the engine
control system will enter an automatic regeneration mode
by elevating the exhaust temperature. The Telehandler can
be operated normally during this regeneration as long as
there are no issues with the high exhaust temperature. If
the Telehandler is being operated in an area where the
high exhaust temperature could cause problems, such as
