If your cordless rivet gun is given up on you, going through the following four causes might be more helpful than blaming the quality of the tool. Believe or not, these causes claim 90 percent of the tool failures:
First, nose assembly maintenance
Cordless rivet guns need to be maintained, especially in the nose assembly area. Depending on the quantity of rivets being installed, the maintenance frequency varies from once a month to daily. Otherwise, the accumulation of rivet swarf in and around the jaw case and jaws will cause the jaw mechanism to malfunction. As a result, this can create a significant damage to the nose housing and cause great stress on the gear box. Fortunately, the latest range of Gesipa® CAS cordless rivet guns have been programmed to slow down the jaw assembly on the return stroke to reduce the possibility of a failure in this area.
Here is an example of swarf build up in the inside front of the nose assembly:
Evidence shows that setting aluminium/aluminium rivets, such as Bulb-Tite® rivets, will leave more swarf in the nose assembly and jaw case. If you are in this user zone, you will need to pay extra attention cleaning up the nozzle. For maintenance instructions, download the Gesipa Powerbird Pro Jaw Set Maintenance manual.
Second, loosened nosepiece
The nosepiece can become loose and this will cause damage to threads. Make sure the nosepiece is tightened before using the tool; and it must be tightened with a 12mm spanner.
Third, nosepiece selection
The Gesipa rivet gun is supplied with a selection of nosepieces. They are stored under the sliding hex key. To avoid tool failure, choosing the right-sized nosepiece for the rivets you are installing is key.
For the Gesipa® Bulb-Tite® rivets, the mandrels are slightly thicker, therefore, correct “BT” nosepiece is required to allow extra room for the mandrels to be inserted. A table below gives you an idea of selecting the correct nosepiece for your job.
Alternatively, you can use the Gesipa nosepiece finder to choose the right nosepiece.
Last, but not least, emptying the mandrel collector
The mandrel collector needs to be emptied regularly to avoid the spent mandrels jamming inside the tool. If you ever wonder how often it needs to be done, the rule is to empty it when its half full. Alternatively, you can contact us to buy a transparent collector, which allows the amount of spent mandrels to be monitored constantly.
