FEED
To turn the ball feed ON, press the green oval button marked BALL FEED ON/OFF. This will start the ball feed carousel. The feed control button (located on the far left of the control panel) adjusts the timing between shots. The feed adjustment goes from 1 - 9 with 1 as the slowest (8 seconds) and 9 as the fastest (1.5 seconds). For safety reasons, if no balls have been fired for 20 seconds, the ball feed shuts off automatically.
SPEED
This control adjusts the speed of the tennis balls shot from the machine. The speed adjustment goes from 1 - 20 with 1 as the slowest (20 mph) and 20 as the fastest (90 mph).
SPIN
This control adjusts the amount of spin on the ball. This control is calibrated with 0 as the no spin position, 1 to 5 as the top spin positions and -1 to -5 as the back spin positions.
SHOT POSITION
Refer to the diagram on the control panel to locate the seven different positions. A player can program up to six different shots. To program a shot sequence, begin with SHOT 1 and work down to SHOT 6. To program fewer than six shots, program the number of desired shots, then program the remaining shots to zero.
SEQUENTIAL DELIVERY
Activate this option to shoot balls in the order in which they were programmed.
RANDOM DELIVERY
Activate this option to shoot balls randomly from the programmed positions.
