1- GENERAL

1.1 - Safety rules

Basic precautions must be observed when using Koehler Instrument Company, Inc.

instruments and their accessories.

1. Read and understand in full these instructions prior to use.

2. In the case of damage or dropping of the appliance, have it examined by a

qualified technician.

3. Do not touch parts of the appliance which become extremely hot.

4. Do not use with a defective connection cable.

5. Do not allow the connection cable to hang over the edge of a table or touch a hot

surface.

6. If an extension lead is necessary, use a cable suitable for the current intensity

that will be used. Using a cable of too small a cross-section may cause

overheating. The cable must not be twisted or stretched.

7. Disconnect the appliance from the mains power when it is not in use. Never pull

on the cable to disconnect it from the mains. Take hold of the plug and remove it

from the power socket.

8. Allow the appliance to cool completely before moving it. Wind the cable loosely

around it for storage.

9. To avoid danger of electrocution, do not immerse the appliance in water or any

other liquid.

10. Do not disassemble the appliance, but have it repaired by a qualified technician

when intervention is necessary. Any incorrect assembly may result in electric

shocks on restoring it to service. Before using the appliance, the operator must

have:

* Knowledge of manual methods and experience in the types of tests to be

performed.

* Knowledge of the risks resulting from handling products and samples.

Users are advised not to handle containers of hot samples. If it is necessary, this

operation must be performed with extreme caution.
