Boom Control
The boom control joystick has variable motions from the
center position that control boom and tilt functions. It is used
to raise, lower, extend, retract the boom, tilt the carriage (or
attachment), and control auxiliary functions (when equipped
with a carriage or attachment with additional functions).
•
The boom control joystick is a variable speed control.
Function speed is proportional to handle movement. The
more the handle is moved in the appropriate direction,
the faster the corresponding function will occur.
•
Increasing engine speed can increase boom lift and
extend speed.

Attachment Tilt Switch
The Attachment Tilt Switch located on the top of the joystick:
•
Controls the attachment tilt functions by rolling the
switch upward and downward.
•
Is a variable speed switch. Function speed is proportional
to how far the switch is rolled. The more the switch is rolled
in the appropriate direction, the faster the corresponding
function will occur.
•
To tilt the attachment down: Roll switch (A) downward (1)
•
To tilt the attachment up: Roll switch (A) upward (2)
NOTE: The attachment carriage will retain the set angle
throughout boom raising, lowering, retracting, or extending
operations.
