Chapter 1. Safety information
This chapter presents the following safety information that you need to be familiar with before you service a Lenovo notebook computer.
General safety
Follow these rules to ensure general safety:
- Observe good housekeeping in the area of the machines during and after maintenance.
- When lifting any heavy object:
- Make sure that you can stand safely without slipping.
- Distribute the weight of the object equally between your feet.
- Use a slow lifting force. Never move suddenly or twist when you attempt to lift.
- Lift by standing or by pushing up with your leg muscles; this action removes the strain from the muscles in your back. Do not attempt to lift any object that weighs more than 16 kg (35 lb) or that you think is too heavy for you.
- Do not perform any action that causes hazards to the customer, or that makes the equipment unsafe.
- Before you start the machine, make sure that other service technicians and the customer's personnel are not in a hazardous position.
- Place removed covers and other parts in a safe place, away from all personnel, while you are servicing the machine.
- Keep your tool case away from walk areas so that other people will not trip over it.
- Do not wear loose clothing
