Joystick Control
Dependent upon the mode
selected, the joystick can
control the levelwind position,
drum/line speed and tension,
and accessory spider system.
Levelwind Control:
The operator can manually position the drum
and spider levelwinds using the Lateral Rocker
Switch located on top of the control Joystick .
To move the levelwind left, push and hold the
rocker switch to the left. To move the levelwind
to the right, push and hold the rocker switch to
the right. When the switch is
released in either direction,
the
motion will stop.
Continuous pressure or
bumping motions can be
used when adjusting the
levelwinds lateral position.
Drum/Line Control:
Once the operational mode [PULL/TENSION] is
selected, the operator can control the drum
speed/tension and direction using the joystick.
Pulling Mode
:
With the trigger depressed the
operator can rotate the drum forward to payout
the line by pushing the joystick forward. The
farther forward the joystick is pushed, the faster
the drum will spin, thereby increasing line
speed. To decrease speed, pull the joystick
backward toward the operator and the neutral
position.
The joystick trigger should always
be released once the hydraulic brake is
released or after crossing over neutral to
being forward payout rotation- see BRAKE
ON/BRAKE OFF Section.
The joystick itself can
be released once the desired line speed is
achieved, and it will stay in place. To stop the
drum at any time, return the joystick to the
center neutral position with the trigger
released. This allows the operator to set the line
speed for extended operations, without the
need to constantly hold the joystick in position.
To rotate the drum backward and pull in the
line, depress the trigger and pull the joystick
backward toward the operator. The farther the
joystick is pull backward the faster the drum will
spin, thereby increasing line speed. Push the
joystick forward toward neutral to decrease line
speed. To stop the drum at any time, return the
joystick to the center neutral position with the
trigger depressed.
Operation
NOTE: To slowly decrease speed after releasing
joystick, the operator can slowly move the joystick
toward the neutral position. If feathering speed
close to the neutral position, be ready to place the
joystick in the neutral position with the trigger
released or double tap the trigger to set the
hydraulic drum brake and avoid a reverse
equilibrium state and unintentional payout of the
line-
(
see Low Speed Feathering section on page 27).
NOTE: The levelwind is automatically controlled;
however, the operator will need to set the initial
starting position and direction of the levelwind to
being pulling operations-
(See Automatic
Levelwind Control section) .
NOTE: There is a small delay from the time the
joystick is moved out of neutral, to when the drum
will engage. This delay allows the time for the
hydraulic system to raise the pressure needed to
hold any existing line tension to the drum prior to
releasing the brake.
It is recommended that the
operator position the joystick slightly out of the
neutral position, wait until the hydraulic drum
brake releases, then slowly increase drum
speed.
Avoiding abrupt joystick movements will
prevent any rapid jolts or increases in drum speed
when the brake releases.
