REMARK
When setting RAISE detent, if the boom is very close to the position specified by the positioner (approximately
within 2 °), the boom control lever does not set to the detent position.
METHOD FOR RELEASING LOWER REMOTE BOOM POSITIONER
1.
Set the boom between the horizontal level and approxi-
mately 30 cm or more above the ground.
2.
Set the boom control lever to HOLD position and hold down position (a) of switch (1) for more than 1 sec-
ond.
A “beep” sounds and the stop position is reset.
If the boom
control lever is set to FLOAT position while the stop position is reset, the boom is set to the float
mode and moved freely by the external force applied.
REMARK
