It is possible for the machine to move suddenly when the brakes are released. This can cause injury to persons on or near the machine. To prevent sudden movement of the machine, put blocks in front of and behind the wheels before the brakes are released. If the machine is to be towed, be sure that the released brake(s) can be reapplied or that the towing machine can stop the machine that is being towed.

Introduction
