Cleaning Clean machine before performing inspection and maintenance. If inspection and maintenance are done when machine is dirty, it will become more difficult to locate problems, and you could slip on steps and work platform areas and injure yourself. When washing machine, do the following: Wear shoes with nonslip soles to prevent slipping and falling.

If water gets into electrical system, it can cause operation problems. Pick up any tools or hammers that are laying in workplace.
Wipe up any grease or oil to prevent slippery substances, that can cause tripping or slipping.
