Throttle; Two Speed; Bucket Positioning - Terex R190T Operation And Maintenance Manual

4.4 Throttle

The throttle (hand lever) is located to the right of the operator's right leg when
seated in the machine. The throttle controls engine rpm.
• Move the lever forward to increase engine RPM.
• Move the lever rearward to decrease engine RPM.
• Select a lower rpm for work that requires delicate operation of the machine.
• Select a higher rpm for faster travel speed or when more power or flow is
required for a task.

4.5 Two Speed

The R190T is equipped with a two-speed drive system. Low range is best suited
to performing strenuous work or operating attachments. High range is intended
mainly for transporting.
To shift between high and low ranges, push the button on the front of the right
joystick. When shifting between ranges, slow the machine to ensure a smooth
transition. The high range indicator (item 16, section 4.1) illuminates to confirm
high range operation.
Note: If the machine is turned off, the lap bar is raised, or the operator exits the
seat, the machine automatically returns to low range.
4.6 Bucket Positioning (optional)
The R160T / R190T machines can be equipped with feature commonly referred to
as "bucket positioning". The bucket positioning system does not automatically
level your attachment. Instead, it will maintain the current angle of the quick
attach (relative to level) throughout the upward cycle of the lift arms.
The bucket positioning feature can be turned on or off with the switch located on
the dash panel (item 10, section 4.1 ).
Note: During the upward cycle, the bucket positioning function can be overridden
by operating the tilt or curl functions of the joystick.
Note: The bucket positioning feature works on the upward cycle only. The opera-
tor must position the attachment manually on the downward cycle.
