Certain faults or sensor measurements can cause the truck
to go into Engine Shutdown mode. The following actions
occur when truck is in this mode:
The VSM will have a coolant over-temperature light come
on at 110 °C (230 °F). At 110 °C (230 °F), the engine will
be limited to 75% power. A linear power regression will be
applied between 110 and 116 °C (230 and 240 °F). At
116 °C (240 °F), the engine will be limited to 50% power.
If vehicle is equipped with an optional power train protec-
tion, at 116 °C (240 °F) and at the end of the 30-second
countdown, all power to the lift truck is turned off. After
shutdown has occurred, recycle power to ON, load can
then be lowered without starting the engine.
CAUTION
If lift truck experiences an engine shutdown, call a
service technician immediately. Continued operation of
lift truck after engine shutdown can cause damage to
the lift truck and its components.
To restart the lift truck, turn the key switch OFF and ON
again to cycle the system power. If lift truck is equipped
with the Power ON/OFF button, press Power ON/OFF but-
ton twice to cycle the system power and then press the
Engine Start button. If the Engine Start button is pressed
before the Power ON/OFF
button, the starter will not oper-
ate. See Starting Procedures, Trucks With Keyless
Start Option in this section, if starter becomes disabled.
When the lift truck has been restarted, it will run for 30 sec-
onds before shutting down again. Cycle the truck power
again to run the lift truck for another 30 seconds. This proc-
ess provides enough power for the lift truck to move under
its own power so that it can be moved to a safe location.
Some faults or sensor measurements will not always cause
the engine to shutdown, but will cause the speed of the lift
truck to be restricted, or will either disable or restrict the
truck's hydraulic functions.
When this occurs, the following actions take place:
• The fault number is displayed on the top line of the LCD
screen and a description of truck performance being
decreased is shown on bottom line.
• The Engine Malfunction icon illuminates (see Figure 7
and Table 3).
• An alarm will sound for 10 seconds.
