1.1 Safety / Machine Preparation Information

11.1 Personal protection

C CAUTION – Always wear protective glasses, shoes, and any other protective equipment as
required by job conditions and machine.

C CAUTION – Wear protective glasses when using pressurized air or water to clean surfaces
or cleaning overhead surfaces.

C CAUTION – Use proper protective welders clothing if a welding operation is to be done.

C CAUTION – Do not wear loose clothing or jewelry that can catch on machine parts or
tools.

C CAUTION – Use steps and handrails when entering or exiting a machine while facing the
machine.

C CAUTION – Use caution when checking for hydraulic leaks and system operation. Do not
use bare hands to check for leaks. Pinhole leaks can result in a high velocity fluid stream
that can penetrate the skin and cause serious injury. Stand clear and use a board or
cardboard to check for leaks.

C CAUTION – Battery posts, terminals and related accessories contain lead and lead
compounds. Wash hands after handling.

11.2 Machine cleaning

C CAUTION – If the machine has been used to apply agricultural chemicals, the machine
must be steam cleaned to remove any chemical residue from the areas where the
