Level 3
The truck is not operational in Level 3. To enter this
level, power up the truck. Step off the floor pedals, al-
low the truck to time out (L and P contactors to de-en-
ergize) and press the down arrow until Service is dis-
played. Press the right arrow and Level 2 will be
displayed. Press the down arrow and Level 3 will be

Once you are in Level 3 you can step on the floor ped-
als. The L contactor will not energize and you will not
have forward or reverse travel.
Note: Once maintenance Levels 2 or 3 are entered the
truck must be turned OFF then back ON to exit the Ser-
vice menu.
Bleed Quick Disconnect
Bleeding the quick disconnect circuit minimizes the
force needed to connect/disconnect attachment hoses
to/from the quick disconnect fittings. This menu allows
the operator to easily bleed the pressure from the quick
disconnect circuit. To enter this menu, power up the
truck while standing on the floorboard (L and P contac-
tors must be energized). Press the down arrow until
Service is displayed. Press the right arrow and Level 2
will be displayed. Press the down arrow and Bleed
Quick Disconnect will be displayed. Press the enter ar-
row. Pressing the enter arrow signals the ACCESS
modules to energize the accessory solenoid valve(s)
opening a path for pressurized oil to return to the res-
ervoir. This only takes a brief moment. The display
message will then change to "Re-key Required". The
key switch must then be turned OFF then ON to re-
sume normal truck operation.
