Random is the default position. TWO LINE DRILL: The machine moves from side-to-side in a pre-programmed setting, delivering balls to two specific points on the court. This allows for the placement of two lines of students or two students hitting balls. The two positions can be adjusted by changing the width of the sweep. There is a six second delay between shots, to allow coaching between shots. This feature will only work at ball speeds above setting #6. The unit senses when a ball is shot, and then moves to the other side. WIDE & NARROW ADJUSTMENT: The wide and narrow switch controls the width of the sweep. To adjust depress and hold until desired width is reached. STATUS INDICATOR: The low battery light will illuminate when the battery is in need of charging. RESET: If your model #4 does not have a reset switch, all resets are internal and are automatically triggered. If your machine is equipped with a reset switch, it will pop out about 1⁄4 of an inch when activated. In the event the reset is activated, turn off the main power, depress the reset switch, turn on the main power, and resume operation. If the switch is activated shortly thereafter, check for balls jammed inside machine. If this does not solve problems, follow directions outlined in the maintenance section. REMOTE: The remote for this model is a ten function remote that controls the sweep (on/off, wide/narrow, and random/ two-line), elevation (up/down), speed (fast/ slow), feed (fast/slow, on/off and one shot), pause, and the spin (back/top). Pause will stop all motors at point of play. When pause is pressed a second time, the machine will start up again at the same point at which it was paused. The most efficient way to use the remote is to adjust the settings on the control panel as close to the settings desired and then use the remote control to make minor adjustments. Once the remote is used the settings changed are held in memory and are kept there until a setting is changed directly on the control panel and then all settings go back to the control panel settings. BATTERY OPERATION PLUG: For proper machine operation, this plug must be inserted into the accessory receptacle located just above the control panel. The plug is attached to the control panel via a chain. 7 BATTERY INSTRUCTIONS One can expect to get approximately four hours of continuous use (no breaks). However by using lower speeds and turning the machine off during reloading tennis balls, playing time may be extended to as much as six hours. Please see accessories for options to extend playing time. The following are requirements to ensure proper performance of sealed lead acid batteries and should be followed precisely: • Charge battery as soon as possible after use. • Do not store battery in discharged state. • Do not store for longer than 30 days without charging. BATTERY REPLACEMENT: After A red light will illuminate on the charger indicating that it is charging. A green light will come on when the battery is 100% charged. At this point, the charger enters a float charge, to prevent the possibility of overcharging. It is recommended to leave the charger plugged into the machine and plugged into the outlet when the machine is not in use. PRACTICE SETTINGS Ground Strokes or Volleys: BEGINNER: To practice the proper form for ground strokes or volleys, raise the elevation height three feet above the net. Turn speed and feed knobs to “4” with spin dial in the “0” position. To practice forehand and backhand, turn sweep switch to the “On” position. removing housing (please refer to page 9 for housing removal), remove battery wires, strap screws, and the battery. When reinstalling the battery, connect the red battery wire to the red battery terminal, and the white battery wire to the opposite battery terminal. Disposal: See instructions on battery. INTERMEDIATE: For intermediate STANDARD CHARGER: To charge ADVANCED: For deep and hard ground the battery, insert the charger plug into the receptacle labeled “charger receptacle” on the control panel (insert into the “Accessories Plug” on the Model #4). The power switch must be off at this time. Be sure to plug the charger into the machine first and then into the outlet. If the standard charger is plugged in for longer than 48 hours the charger will cause permanent damage to the battery. FLOAT CHARGER (OPTIONAL): The optional float charger can be purchased as an accessory. The float charger is designed to allow continuous charging without causing damage to the battery. 8 play, raise the elevation height approximately two feet above the net. Turn on the speed and feed knobs to “5” with the spin dial turned to “3” either way (backspin or topspin). To practice forehand or backhand, turn sweep switch to the “On” position. strokes or volley, raise the elevation height six to twelve inches above the net. Turn the speed and spin dial fully clockwise. At full speed you will have to bring the machine back a couple of feet past the baseline similar to the positioning of a higher level player. For intense workout, turn sweep switch to the “On” position. OVERHEADS: Position the ball machine to throw balls down the center of court. Adjust the elevation height up for lobs (or use attachable lob enhancer) and turn down the ball feed. Practice hitting lobs at each corner. TRANSPORTING For ease of transport, the Prince® Portable Ball Machine has a handle that pulls out, and wheels on the front of the machine that are durable enough to handle almost any terrain. It is not a good idea to try to pull the machine up or down stairs as the base plate can be bent and cause the machine to be unable to roll. of machine. You cannot lift the housing straight up due to wires that are attached, but you can tilt it backwards. This gives you plenty of access to look inside the machine. When putting the housing back on, be sure the motor support column is behind the alignment screw (see picture below). You should be able to feel the tip of the alignment screw with your finger and the support column behind it. If you can’t feel the alignment screw, pick the housing up 3 inches and realign. PERIODIC INTERNAL CLEANING: The frequency of cleaning STORAGE Store the Prince® Portable Ball Machine in a clean dry place. Charge the battery before storage. Be sure to read the battery section for more information about long term storage. Avoid extreme temperatures. MAINTENANCE HOUSING REMOVAL: Using a 5⁄32” Allen wrench, remove the four Allen screws, two on each side of housing. Carefully lift and tip housing towards control panel side Incorrect will depend on the use of the machine. For casual use (less than once a week), the cleaning procedure should be performed once every six months. For extensive use (more than twice a week), the cleaning procedure should be performed every three months. INTERNAL CLEANING PROCEDURE: Step 1: Remove housing following steps in Housing Removal section. Step 2: Brush or vacuum off ball felt and any other foreign materials that have accumulated on the unit’s interior. Step 3: Complete, in reverse order, the Housing Removal steps. Caution: Be sure to connect the red battery wire to the red battery terminal and the white battery wire to the opposite battery terminal. Correct 9 TROUBLESHOOTING GUIDE Q. Every once in a while the machine shoots out two to three balls at a time. What is the problem? A. If the wheels are unable to handle a ball, the balls back up and push the errant ball through. This causes all balls that have dropped through the hopper to exit back to back. First, check for any foreign material in the ball chute that would cause a ball jam. Second, check the surface of the throwing wheels. If they appear dirty or have a wax build-up, remove the housing and clean the wheels with a wire brush. With the machine in the off position (and unplugged), clean the wheels with a side to side motion. Occasionally wet tennis balls may cause this problem as well. Extra felt or heavy duty tennis balls are slightly larger than normal tennis balls and multiple firing may occur more frequently when these types of balls are used. Q. A. 10 The machine turns on, but instantly shuts down or gives low battery indication. What is wrong? This could mean that either the battery is low or something is prohibiting the machine from going through its normal power up procedure. With machine off, check behind ball throwing wheels to make sure there is no ball jam. If wheels turn freely, recharge battery. Q. The machine is only shooting to the right or left of the court when it is adjusted to the widest oscillation angle. What is the problem? A. The oscillation base must be facing forward for the machine to oscillate properly. Be sure to align lines (see alignment on page 3). Q. My remote is not working. What do I do? A. Check the batteries in the remote. If this does not help, follow the Housing Removal steps on page 9. Then locate the receiver and make sure that all wires are connected and clean with soft brush or vacuum.

The converter enables the machine to be run from any standard electrical outlet. The converter also works as a fast charger when the machine is off. Note: The converter utilizes the battery to assist in the start up of the machine. It is recommended to leave the converter plugged into the machine while the machine is not in use. The converter is silver in color. This is a great option for anyone interested in using the machine for hours at a time. The extended life battery is an option that allows the machine to run an additional eight to ten hours. It weighs 30 lbs., comes with a custom carrying case, fast charger, and connecting cable. To charge the extended life battery, plug the charger into the plastic receptacle on the battery and plug the other end of the charger into an electrical outlet. The red light on the charger will show that it is charging, and the green light will illuminate when the battery is 90% charged. The time required for a full charge on the extended life battery is approximately 8 hours. Cover: The cover is designed specifically for the machine. To cover the machine for storage with balls in the hopper, use cover fully unfolded. To cover the machine for storage with the hopper in storage position (see photo #1 on pg. 2), fold the bottom of the cover and attach to the inside via Velcro. Lob Enhancer: This attachment produces game perfect lobs. This attaches to the two holes located on the front of the housing. To use, raise the elevation so that the ball deflects off the top of the lob enhancer. To use the extended life battery, unplug the charger and plug one end of the battery cable into the extended life battery and the other end into the machine. When attaching the cable on the Model #4, please verify that the proper ends of the cable are attached to the correct receptacle. The cables are color coded for your convenience.
