BATTING PRACTICE

THE WINDUP (getting ready to pitch)

1. Before turning the on/off switch “ON”, make sure all three speed control dials are set at “0”. Now turn the on/off switch to “ON”.
2. Set the speed control dials*:
   Top Left to “10”
   Top Right to “10”
   Bottom to “9”

• This is the average setting for a Little League fastball. 3. Check again to make sure no one is in front of Junior Hack Attack or anywhere near the batter’s box. Then, feed a ball down the ball chute to pitch the first ball. 4. Note where the pitch goes in relation to home plate. Adjust the pitch to the left or right by shifting the rear leg:
  1. To move the pitch left, move the rear leg to the right.
  2. To move the pitch right, move the rear leg to the left.
  3. Adjust the elevation:
  4. Turn the elevation control clockwise to raise the pitch.
  5. Turn the elevation control counter-clockwise to lower the pitch.
  6. Adjust the speed control dials to produce the required speed. Larger numbers equal higher speed.
  7. Pitch a second ball.
  8. Repeat steps 4, 5 and 6 until the proper path, elevation and speed are achieved.
  9. Refer to “Selecting the Pitch”, page 7, for different pitches.
  10. Pitch several more test balls to ensure the selected pitch repeats.
  11. After you are sure desired pitch is repeating, allow the hitter to step into the batter’s box.
  12. See Figures 3 and 4 at left.
  13. Before each pitch present the ball to the hitter.
  14. Place ball at the top of the ball chute, seating it firmly against the ball chute.

AND… THE PITCH
Proper feeding technique is important to take advantage of Junior Hack Attack’s life-like vision and timing.

When feeding:

1. Be sure hitter is ready.
2. Present the ball to hitter by raising it approximately to eye level (See Figure 3), then place ball at the top of the ball chute, seating it firmly against the ball chute. The ball should be held back against the chute to ensure a smooth consistent feed (See Figure 4).
3. Release the ball to roll down the ball chute and into the throwing wheels.

WARNING
HAZARD FROM HIGH-SPEED PROJECTILES
Being struck by a pitched ball can cause serious injury or death. Make sure that no one steps in front of Junior Hack Attack while it is connected to electric power.
Clear all hitters away from home plate, the batter’s box and the backstop area before connecting machine to electric power.

NOTE: As wheel speeds are changed for different velocities and spins, the ball will be pitched to differing locations. Compensate for these changes by turning the elevation control, and by moving the rear leg.

Figure 4 Feeding the ball
IMPORTANT: Hitter should stride the instant he sees the ball release from the feeder’s hand at the upper end of the ball chute.

SELECTING THE PITCH

NOTE: Vertical (Elevation) and horizontal (swivel) must both be adjusted whenever you change speed or spin.
Always have the batter step away from the batter box before adjusting speed or spin.

BALL SELECTION

1. Never mix leather balls with synthetic pitching machine balls.
2. Be careful not to mix new with old balls, or balls from different manufacturers.
3. Balls must be consistent in type and amount of wear to produce repeatability.
4. NEVER USE WET BALLS!

Leather balls work well but will wear faster than synthetic pitching machine balls. Watch to see that leather balls do not begin to soften from the great amount of hitting they will receive.
Discard old or soft leather balls from your Junior Hack Attack batting sessions. Similarly, discard older worn synthetic pitching balls.

Figure 5 Pitch Selection Chart – These settings are provided as general guidelines. Adjustments for players of varying skill can be made from these settings.

WARNING
PERSONAL INJURY HAZARD
Never reach down near throwing wheels for any reason! Always turn all three speed control dials to “0”, turn the on/off switch “OFF”, unplug Junior Hack Attack from the power source and wait until the throwing wheels have come to a complete stop before reaching hands or fingers anywhere near throwing wheels.
