OPERATION
7.OPERATING THE BOOM JOYSTICK CONTROL
Positioning the boom is performed with electronic valves controlled by the operator using a single joystick.
The joystick controls five standard operations: Swing, Lift, Dipper, Head, Tilt, and Door. Of these five
operations, the Swing, Lift, and Dipper functions are proportional; that is, when the joystick is moved a small
amount, the cylinder moves slowly and as the joystick continues to be moved, the cylinder continually
becomes faster. This allows very precise positioning of the boom. Using a single joystick, many of the
functions can be operated simultaneously such as the Lift and Dipper for even greater speed at positioning of
the boom.
For safe and efficient boom mower operation, it is critical that the operator be experienced and feel confident
in using the joystick control to position the boom. New operator’s should allowed ample time to practice using
the joystick in an open area before entering the worksite. Before attempting to operate this equipment, read
these instructions completely. If you have any questions concerning safety of operation, contact your dealer
or ALAMO INDUSTRIAL.
Each joystick control and responding boom action is covered in detail on the following pages. Read each
explanation carefully then practice in a safe, level area, CLEAR of all people, animals, and any obstructions.
As always, use extreme caution when using this machine.
Practice performing multiple functions simultaneously. With some practice, the joystick will become very easy
to operate and will feel almost as it were an extension of your arm.
With the exception of the relief valves, which are preset at the factory, these are all the controls for operating
the machine other than the controls on the tractor itself.
Master Switch
Operating any joystick function requires that the joystick Master Switch be ON. When
ON the master switch indicator light will be illuminated. Turning off the master switch will
deactivate all joystick controls. The master switch also serves as a safety device and
will prevent the tractor from being started if the master switch is in the ON position.
OPS-B- 0030_A
Operate the Tractor and/or Implement controls only while properly seated in the Tractor seat
with the seat belt securely fastened around you. Inadvertent movement of the Tractor or
Implement may cause serious injury or death.
