The safety systems installed on your machine should be checked before each machine use. Be sure you have read the machine operator manual and are completely familiar with the operation of the machine before performing these safety system checks.
Use the following checkout procedures to check for normal operation of machine.
If there is a malfunction during one of these procedures, do not operate machine. See your authorized dealer for service.
Perform these tests in a clear open area. Keep bystanders away.
