Stopping Travel
Warning
To prevent death, serious injury, or property
damage, apply service brakes until the forklift
comes to a complete stop, move travel select
lever to NEUTRAL (N), set the Parking Brake
switch to ON (engaged), lower and retract the
boom, and shut off the engine before exiting the forklift.
1.
Stop the forklift by applying the service brake pedal.
2.
Slow the forklift until it comes to a complete stop.
3.
Move the travel select lever to NEUTRAL (N).
4.
Set the parking brake to ON (engaged).
Diesel Exhaust Fluid (DEF)
The DEF tank should be filled after every fuel refill.
DEF
should be added when the Low DEFLevel indicator is displayed.
Refer to the Operation section on
Warning Indicators and
Fault Codes
and the Engine Indicator Chart (Fig. 67). The total
capacity of the DEF tank is 5 gallons.
If no DEF reagent is available in the DEF tank, the emission
requirements cannot be fulfilled and the machine derates
eventually to idle only, following a predetermined schedule.
Warning
Fig 68. Fill the DEF tank at every fuel refill. Add DEF (Diesel Exhaust Fluid)
when the Low DEF Level indicator is displayed.
Caution
Using anything other than DEF fluid may result in permanent
aftertreatment damage.
