Batting Practice
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 3 Present the ball to the hitter
Feeding the ball
IMPORTANT: Hitter should stride
the instant he sees the ball release
from the feeder’s hand at the up-
per end of the ball chute.
BATTING PRACTICE
THE WIND-UP (getting ready to pitch)
1. Turn the on/off switch “ON”.
2. Set the speed control dials*:
Top Left to “4”
Top Right to “4”
Bottom to “7”
* This is the average setting for a high school fastball.
3. Check again to make sure no one is in front of 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:
a. To move the pitch left, move the rear leg to the right.
b. To move the pitch right, move the rear leg to the left.
5. Adjust the elevation:
a. Turn the elevation control clockwise to raise the pitch.
b. 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.
a. Before each pitch present the ball to the hitter.
b. Drop the ball into the ball chute.
AND… THE PITCH
Proper feeding technique is important to take advantage of 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, 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.
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 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

Batting Practice
BATTING PRACTICE (cont’d)
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 Hack Attack batting sessions. Similarly, discard
older worn synthetic pitching balls.
Figure 5 Pitch Selection Chart - These settings are a general guideline for professional pitches
for major league hitters only. Adjustments for players of lesser 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 “OFF”,
turn the on/off switch “OFF”, unplug
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.
•
Never loosen the horizontal swivel
lock while pitching to a batter.
If the lock is not secure, the
throwing head is free to pivot.
A loose swivel lock can allow a
pitch to be inside which could hit
the batter.
