Cleaning and Maintenance

The Tech 2 needs continual maintenance to keep it improper working order. By following the simple instructions in this section you can make sure that the instrument will provide trouble-free operation for a long time ahead.

Carry out the following steps after using the Tech 2:

1. Turn off the Tech 2 by pressing "PWR". Then unplug the cable from the mains outlet and the Tech 2 instrument.
2. Check that the cable and its connectors are undamaged and free from corrosion.
3. Check that the display, keypad, cable connections and connectors are free from dirt, spots and stains, etc.

Impurities in various forms which stem from aluminium, acids, chlorides, silicone, manganese, iron and carbon may occur in the air at a garage or workshop.

Such impurities attack the outer surface of the Tech 2 as well as its cables and adapters.

Maintenance of the Tech 2 includes regular cleaning of the casing, display, keypad, cable connections and connectors. Perform the cleaning instructions that follow for best results.

WARNING: Turn off the Tech 2 and unplug the cable from the mains outlet before starting to clean the instrument.

IMPORTANT: Do not use cleaning agents containing solvents or petroleum products.

NOTE: Although the Tech 2 is a moisture-resistant instrument, it is not entirely moistureproof. It is therefore advisable to wipe it thoroughly dry after it has been cleaned.

Cleaning The Casing
Wipe the casing clean using a soft cloth moistened with a mild detergent or soap solution.

Avoid using petroleum-based products like acetone, benzene and trichlorethylene as they contain chemicals which can damage plastic surfaces.

Display Maintenance
Dirt adheres to the display in the course of normal usage. Wipe it off with a clean, soft antistatic cloth.

Remove obstinate spots and stains by moistening a soft cloth with a glass-cleaning liquid which is free from abrasives and then wipe the
display clean.

Remove really obstinate spots and stains by moistening a soft cloth with a glass-cleaning liquid and then wipe the display clean.

Cleaning The Keypad
Clean the keypad with a mild detergent which contains no abrasives.

IMPORTANT: Never pour or spray cleaning agents directly on any part of the Tech 2. Use a cloth moistened with the cleaning agent instead.

Maintenance Of Cable Connections And Connectors
Inspect all cable connections and look along the cables for nicks and worn or abraded parts. Inspect the connectors and their pins to see whether there is any grease, dirt or rust on them.

If dirt is present on the outside of cable connections and connectors, it can be wiped off with a mild soap solution.

Change the cable connections if their contact pins are worn or corroded.

Storage Of The Tech 2
Keep the following information in mind when the instrument is to be stored away:

^ Since the Tech 2 is not an entirely moisture-proof instrument, store it away from solvents and other liquids.
^ Ultraviolet radiation and infrared light will darken the display, so store the Tech 2 away from direct sunlight.
^ Since the impact-resistant casing of the Tech 2 can get scratched, keep the instrument packed in its carry case.
