The upgrade from your EISENHORN 3, 4 or 5 to Generation 7 is quick and easy to install. To do this, proceed as follows:
Dismantle and dispose of the restraint rope, the rope clamp and your existing horn.
Keep the stop bolt and follow the individual steps in the enclosed instructions to install your upgrade.
After fitting your new horn, move it towards the piston.
The new ‘magic retention function’ keeps your horn securely in place even without a restraint rope. During assembly, you move the new horn with slight pressure over a small resistance point – exactly where your horn meets the stop bolt. So, every time you switch between the parking and training positions, you will feel a slight resistance. Working invisibly in the background, this new development ensures that your horn remains securely and stably in the desired force level in the training position.
For the upgrade, you also need to replace the bolt on the piston – two suitable bolts are included in the scope of delivery. As the bolt is secured with Loctite, a vice is helpful and necessary for the replacement.
Tip: You can loosen your piston pin more easily by using a hot air dryer. To do this, point the hot air gun directly at the piston pin at the highest temperature setting for about 3 minutes and at a short distance. You can then loosen the pin with a ring wrench and replace it. As the heated piston pin is hot, please do not touch it without suitable gloves.
You will find all the steps for the conversion in the enclosed and detailed instructions.
Please note that this upgrade is only compatible with EISENHORN generations 3, 4 and 5. Earlier EISENHORN generations are not compatible with this upgrade. If you own an EISENHORN of generation 6, please select the upgrade 6 to 7. You will find information on the generation of the appliance on the rating plate. Depending on the appliance, this is either on the column or on the carriage (back of the center section).
