SET-UP & PREPARATION
1. Be sure the horizontal swivel lock is tightened securely (See Photo A).
2. Turn the elevation adjustment clockwise until the throwing head is held tightly
against the frame lock pin (See Photo B). Tighten just enough to secure the throwing
head. It is not necessary to over tighten.
3. Install the long, rear leg (NOTE: the leg has a push button, which locks the leg into the
socket) Roll Junior Hack Attack onto the mound approximately four feet in front of
the rubber. The long leg is used for transporting only.
4. Tilt Junior Hack Attack forward until it rests on the throwing wheel guard.
See Figure 2, Page 4.
5. Insert the two front legs into the front sockets in the undercarriage (NOTE: the front
legs also have locking push buttons). Then remove the long, transport leg and insert the
short leg into the rear leg socket.
6. See Figure 3 on page 4.
Walk around to the front of Junior Hack Attack, and, with your back to home plate,
reach down and grasp the wheel guards. Then, lift machine up and over the front
legs and set it gently onto the rear leg.
7. Position Junior Hack Attack:
a. For optimal performance, position the Junior Hack Attack so the release point
is approximately 46 feet from home plate.
b. Then, sight down ball chute. Move the rear leg right or left to adjust machine so
that it is pointing directly at home plate.
c. Check the horizontal swivel lock to make sure it remains tight.
8. Unlock the frame lock (See Photo C). Turn the handle of the elevation control
counter-clockwise until the travel lock pin drops out of the way.
9. Adjust the throwing head:
a. Turn the handle of the elevation control clockwise. Raise the throwing head
until it will throw somewhere near the required height.
b. This initial adjustment will come through experience. To start, turn the elevation
adjustment 10 turns clockwise.
10. Examine Junior Hack Attack for condition and completeness:
a. Be sure the horizontal swivel lock is secured (See Photo A).
