When the remote boom positioner is enabled, the boom stops
at the preset position and the lever returns to “HOLD” position
at the same time.
When the remote boom positioner is disabled, the boom stops
at the highest position and the lever returns to “HOLD” position
at the same time.
Position (b): HOLD
The boom and bucket remain in the positions where they are stopped.

KICKDOWN SWITCH
When traveling in FORWARD 2nd, if kickdown switch (2) is
pressed, the gear is shifted down to FORWARD 1st.
Use it to increase the rim pull during scooping.
When the transmission shift range (actual gear speed) is at
FORWARD 1st (F1) and the power mode selector switch is set
to E light mode or E mode, if the switch is pressed, the power
mode changes to P mode.
Use this switch to increase the rim pull further during scooping
or for scrape-up work.
