4. Tower Boom Horizontal Cut-Out
With the tower boom above horizontal, HIGH DRIVE and
2 SPEED are cut out. In addition, with tower boom
above horizontal, selecting DRIVE or MAIN LIFT cuts out
HIGH ENGINE on TOWER LIFT and TOWER TELE-
SCOPE functions, DRIVE function automatically goes to
CREEP mode, and HIGH ENGINE is cut out except as
noted in step (9).
5. Axles/Axles Jack Cut-Out
To retract axles or operate axle jacks, ground controls
must be selected, booms must be below horizontal and
between drive wheels.
6. 5° Tilt Cut-Out
When machine is on a 5° slope, 2 speed is cut out,
regardless of tower boom position. In addition, if tower
boom is above horizontal with machine on a 5° slope,
drive function is cut out and all other functions automati-
cally go into creep mode.
7. Tower Boom Cut-Outs
Tower telescope and main lift are cut out unless tower lift
is fully up. Tower lift is cut out unless tower telescope is
fully in and main lift is fully down.
8. Main Boom Lift Cut-Out
When main boom lift is operating, lift speed automati-
cally goes into the creep mode 18° before each end of
the lift cylinder stroke.
9. Tower Lift and Tower Telescope Cut-Outs
When activating Tower Lift UP or DOWN or Tower Tele-
scope IN or OUT, high engine is activated at full control-
ler stroke. This feature can be turned off at platform
controls using HIGH ENGINE switch.
10. Auxiliary Power
When auxiliary power is activated, the CREEP function
does not work. In addition, if engine is running and aux-
iliary power is activated, the engine will shut off. This
prevents the operator from increasing function speeds.
