Safety information
Before you service an IBM computer, you must be familiar with the following
safety information.
General safety
Follow these rules to ensure general safety:
v Observe good housekeeping in the area of the machines during and after
maintenance.
v
When lifting any heavy object:
1. Ensure 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.
4. 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 objects that
weigh more than 16 kg (35 lb) or objects that you think are too heavy for you.
v Do not perform any action that causes hazards to the customer, or that makes
the equipment unsafe.
v
Before you start the machine, ensure that other service representatives and the
customer’s personnel are not in a hazardous position.
v
Place removed covers and other parts in a safe place, away from all personnel,
while you are servicing the machine.
v Keep your tool case away from walk areas so that other people will not trip over
it.
v Do not wear loose clothing that can be trapped in the moving parts of a
machine. Ensure that your sleeves are fastened or rolled up above your elbows.
If your hair is long, fasten it.
