Ace Attack™ Assembly
ASSEMBLY
NOTE: We recommend that two people complete the Assembly instructions. Because of that, the instructions are
written for two people to complete.
1. Unbolt machine from the pallet. Two people should stand on opposite sides of the Ace Attack from each other
and carefully move the machine off the pallet.
2. Tip machine to one side so that one person can prop/hold it up while the second person installs two casters
with the tool provided (see Figure 3, Page 4). Then lean machine in the opposite direction so that the
remaining two casters can be installed. Be sure to fasten all four (4) casters securely using the wrench
provided (see Figure 3, Page 4).
3. Place the ball bin into position on the top of the throwing head at “A” (Figure 4). Install the three (3) bolts as
shown in Figure 4. Tighten bolts securely.
NOTE: There is one 2” bolt and two 2 1/4” bolts with washer and nut.
NOTE: Tighten casters securely using the wrench provided (see Figure 3, Page 4).

tube over the tube attachment on the bottom of the ball bin. When the tube has been pushed all the way,
release the tube attachment. Finger-tighten the two thumb screws to secure the ball feed tube.
See Figure 5 and Figure 6 on page 7.
5. Following the same procedure, attach the opposite end of the Tube.

Ace Attack™ Operation
OPERATION
POWER SWITCH & CIRCUIT BREAKER
1. This is the main power switch that energizes the entire machine. Nothing will operate until the main
switch is turned “ON.” Be advised that there is a five (5) second delay once the machine is energized, as indicated on the label.
2. Circuit Breaker: When the circuit breaker is activated, turn the on/off switch “OFF.” Also turn the feeder and
throwing wheels “OFF.” Allow machine to sit a few minutes and cool. After several minutes, push
the circuit breaker back “ON” and power should be restored.

Ace Attack™ Operation
OPERATION (cont’d)
THROWING WHEEL OPERATION
General: Throwing wheels impart velocity and spin to the ball. The higher the RPM,
the faster the ball goes. Spin is imparted when the wheels are turning at different
RPMs. The greater the difference, the greater the spin. RPM increases as you turn
the dials clockwise and decrease as you turn the dials counter clockwise. When
all wheels are turning at the same RPM, the ball is imparted with no spin.
THROWING HEAD HEIGHT “RAISE/LOWER” SWITCH
For ground strokes, press and hold the “LOWER” switch until the throwing head
is all the way down. For serving, press and hold the “RAISE” switch until machine
reaches the desired height. “Reverse” - start with raise position.
NOTE: All other functions automatically turn “OFF” when you raise or lower the
throwing head. These functions will automatically turn back “ON” once you stop
raising or lowering the throwing head.
IMPORTANT: Always have the throwing head in the lower position when you are filling
the ball bin or moving the Ace Attack.
FEEDER SWITCH
1. This switch stops and starts the ball feeder. Be sure the throwing wheels
are on before you turn on the feeder. Turning the feeder “ON” before the
throwing wheels are turning will cause the ball to jam.
2. To remove jammed balls, turn the throwing wheel dials to “0” and turn the on/
off switch “OFF” and unplug machine. Loosen tube thumb screws, squeeze
the handles on the ball chute attachment piece at the throwing head and
remove ball feed chute (See Figure 3 on page 7). This will allow you to remove
all jammed balls. Replace ball feed chute and continue operation.

Ace Attack™ Operation
OPERATION (cont’d)
OSCILLATION CONTROL
The Ace Attack provides a variety of oscillation selections:
Single Line: The ball is thrown to the same spot.
Two or Three Line: The ball is thrown to two or three locations on the court. The ball
direction will now alternate between forehand and backhand or throw to two or
three separate lines for group instruction. To set the machine for two or three
positions, position the switch to either the middle position for two-line or the
lower point for three-line, “switch” and select either the two position or three
position option on the adjacent switch that is immediately left.
Two Line “Four Ball” Drill: Used for simultaneously training
two players, or two lines of players, the ball is thrown to the backhand, then
forehand, followed by two (2) balls to the center of the oscillation width.
Random: Randomly automatically throws balls in a sweeping pattern from side to
side to different (or random) spots (locations) on the court
Width Control: This dial controls the distance between shot
locations. The range or distance between shots is infinite and easily dialed. The
width increases as you turn the dial clockwise.
10 = widest
1 = narrowest
Interval Control: This dial allows you to change the frequency or time between shots.
Depth of shot, range of shots, type of shot and method of instruction all require
different intervals between shots. The interval increases as you turn the dial
clockwise.
10 = approximate 10 second interval
1 = approximate 1 second interval
