CAUTIONS

● This machine is not a toy! Use under adult supervision only.

● Machine will throw balls and strikes- batters must stay alert and 
always wear a helmet.

● Use only regulation sports balls, or balls specifically designed for
machine use.

● Hold machine steady when loosening joints for adjustments. The
machine is not fully balanced and may move under its own weight 
if not held in place when clamps are released.

● Use a grounded (3 prong) outlet only. Use a GFCI outlet when 
machine is operated outdoors. Do not use the machine in wet 
conditions.

● Do not store the machine with the urethane wheel tread 
compressed against the ground. Flat spots will develop. Storing 
machine in very hot, humid conditions can accelerate wheel tread 
aging.

● Machine operator (person feeding balls into machine) should 
stay behind a protective screen.
