General safety

Follow these rules below to ensure general safety:

• Observe a good housekeeping in the area where the machines are put during and after the maintenance.
• When lifting any heavy object:

1. Make sure that you can stand safely without slipping.
2. Distribute the weight of the object equally between your feet.
3. Use a slow lifting force. Never move suddenly or twist when you attempt to lift it.
4. Lift it by standing or pushing up with your leg muscles; this action could avoid 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 machine unsafe.
• Before you start the machine, make sure that other service representatives and the customer are not in a hazardous position.
• Please remove covers and other parts in a safe place, away from all personnel, while you are servicing the machine.
• Keep your toolcase away from walk areas so that other people will not trip
