They then repair or replace the necessary parts. The final step is to test the machine to make sure it is running smoothly. When repairing machinery that is controlled by electronics, maintenance mechanics may work with electronic repairers or electricians. These workers maintain the machine's electronic parts. However, industrial machinery mechanics now often need electronic skills to repair equipment on their own.
Mechanics use a wide range of tools.
They may use a screwdriver and wrench to adjust an engine. They may use a hoist to lift a printing press off the ground. Sometimes replacements for broken or defective parts are not readily available or a machine must be quickly returned to production. In these cases, mechanics may sketch a part that can be fabricated by the plant's machine shop. Mechanics use catalogs to order replacement parts and often follow blueprints and engineering specifications to maintain and fix equipment.
