Set-up & Preparation
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 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.
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).
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 pin of the travel lock 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 some where 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).
b. Throwing wheels must be tight on the motor shafts. Check that the keyway retaining
bolts are tight.
c. Wheel guard and ball chute must be securely fastened to the throwing head.
11. Be certain on/off switch is turned “OFF,” then plug Junior Hack Attack into an
extension cord or other power source. (See generator information at right if applicable.)
