Try to minimize injury and accident by wearing appropriate clothes to work on the equipment.

Select clothes that do not attract a lot of electrostatics. Avoid exposing skin even if the

surrounding temperature is high.

2.2. Handling the equipment

Work in accordance with the instructions.

Read the attached Instruction Manual carefully.

Transport and handle the equipment in accordance with the Manual.

Be sure to check the electric power line, water supply/drainage line, and other connection lines

before working on the equipment.
