1. Operators of Jugs Bowling Machines must wear safety glasses and batting
helmets at all times.
2. Check speed dial and make sure it is in the full counter-clockwise position
(pointer at 0 mph setting) and the toggle switch is in the OFF position.
3. Plug heavy-duty no. 18-gauge, extension cord into A/C outlet and connect to
short cord on the bowling machine. Place the protective screen in front of the
bowling machine to protect the operator and the bowling machine from batted
balls.
4. Position the machine to aim at the desired target. While grasping the T-Handle
above the control box, loosen the Lock Knob and adjust the trajectory as
desired. Tighten Lock Knob securely. (You will have to practice this targeting
so you will know how to set the machine for each delivery.) Be sure to tighten
base and leg T-Clamps
5. Place toggle switch in the ON position. Gradually turn the speed dials to the
desired speed.
6. Have all batters and observers stand well clear of the target as you bowl
practice balls. To adjust trajectory and point of aim, use the T-handle, Lock
Knob and Base T-Clamp, (It is normal to bowl five or six balls before arriving
at the setting you desire.) Always have the batter stand clear while adjusting
your JUGS bowling machine.
7. At the beginning of practice, or after any change in speed, curve, or trajectory,
have the batter stand well clear while at least one test ball is bowled to make
sure the ball is bowled at the desired target. If you move the machine for any
reason, repeat this process.
8. Bowl balls at speeds the batter can learn to hit. As the batter’s skills increase,
you can bowl faster deliveries.
9. When you increase the speed of any delivery, you must lower the elevation of
aim; when you decrease speed, you must increase the aim elevation.
