JUGS Sports Combo (2 wheel) Pitching Machine - Manual (Page 29)

Review the following instructions carefully to maintain maximum
accuracy with your JUGS Pitching Machine.
•
Maintain tire pressure at 16 to 17 psi (25 psi for tennis balls).
Cleaning
•
Keep machine clean, and free of grit and dirt. Always use a clean
damp cloth when cleaning. Never use brake fluids, gasoline, petroleum-
based products, or any solvents to clean machine.
•
Periodically, you must clean the tires to help maintain their maximum
performance. A dirty tire can easily be distinguished by either a dark ring
around the tire surface or when the surface itself has turned yellow and
has a very glossy or shiny finish.
•
In order to begin cleaning you must first inflate the tires to approximately
17 pounds.
•
Using medium grade sandpaper (sometimes an even coarser grade is
necessary, depending on the amount of soil buildup) begin to scrub
the tire surface. This process can be very tedious and may take up to
10 minutes per tire. However, it is necessary to completely remove all
foreign substances from the tires to prepare them for better machine
performance. You should sand the tires whenever you notice the soil
build-up forming. Always sand tires with the power switch Off and
the machine unplugged.
Once you complete this operation the tire surface will, in most cases, take
on the white color it was originally. Maintaining the tire in this fashion will
not only maximize the performance and accuracy of your machine, but it
will extend the life of the tire.
Storage
•
Always store machine and extension cord in separate, clean, dry secured
areas. Cover the machine with a suitable dust cover that does not retain
moisture. Do not use plastic.
