Dear Sir or Madam,

hereby we inform you about news and changes that arised in the course of the year.

1. Oil pump SR75

The oil pump of the SR75 has been changed due to a lack of lubrication in continuous vertical operation. Please note that in the case of a repair the bearing seat of the pinion shaft is cut by 0.3 mm deeper and a groove of 10 mm diameter is milled sideways. For this purpose, we provide you with the tool VB30201.
The locking disk SR30232 is then mounted under the bearing of the pinion shaft and the feed screw SR30230-3 in the pinion shaft.

2. DK32 und DK26 Electronic module – circuit board DK30510-1 und DK26510-1

Presumably, for fraudulent purposes, our distributor bought triacs from his supplier who could not stand the required currents. It is still unclear how this mixture with faked triacs could happen. Unfortunately, these fake components could not been recognized during the quality inspection, they only fail during operation.

To select these faked modules, proceed as follows:

A. New machines

On the triac (see picture) the embossing PHIL must be present, if it is missing, it is a fake.
Furthermore, the fake triacs are marked with the trace code “7SAJA”, and the data code “1528” or “1628”.

If you have new machines in stock, please open the terminal box and check the above information. If a fake triac has been installed, please replace the electronics module and return it to us. For this work, we will compensate you with 20 € and we will compensate the electronic module.

B. Machines that are already in operation

Please inform your customers that they check their machines according to the information above. At least they have to check the soft start of the machine. If this is no longer present, that means the machine starts abruptly, the electronics is no longer effective and can also no longer protect the machine against overcurrent.
Please ensure that these modules are replaced immediately before further damage occurs to the motor. We compensate this work with a fixed sum of 25 € in addition to the circuit board.
If higher costs should arise, please provide a separate statement of the financial expenses. Please return the defective modules for inspection and warranty.

We are very sorry that all these inconveniences have arisen. This is a criminal act of a company, which is presumably acting in the Far East and is difficult to catch. We are in contact with ST Microelectronics, whose components have been falsified. We hope that this company is willing enough to find the fraudster.

3. Article numbers

Due to the enormous number of customer-specific machine versions, we kindly ask you to order machines with the correct article number, if they differ from the standard types (WEKA design). Otherwise it cannot be guaranteed that the machines are executed as required.

For customer-specific machine versions, WEKA issues separate customer-specific article numbers, which are listed on the order confirmation, invoice and the delivery note:

Based on this customer-specific article number the execution of the machine is clearly defined in all characteristics.

In particular the customer-specific design of the characteristics color, plug, voltage, name plate and operating instructions lead to a separate customer-specific article number.

We therefore ask you to use your customer-specific article number in future orders to prevent mistakes.

 

With best regards

WEKA Elektrowerkzeuge
