In augustus 2021 riep Petzl eigenaren van een ZigZag of Zillon op om de werking van het apparaat te controleren op doorslippen. LET OP: De termijn waarbinnen je een vervangend product kon krijgen is op 31 december 2022 verlopen!

ARCHIVE
This information concerns only the following products: ZIGZAG (D022AA00), ZIGZAG PLUS (D022BA00), ZILLON (L22A 025, L22A 040, L22A 055) with serial numbers between 18L 0000000 000 and 21G 0000000 000.
Customer returns alerted us to slippage with new or slightly used ZIGZAG / ZIGZAG PLUS / ZILLON products. Following our technical investigations, we were able to identify the causes of the slippage. They are related to a variance in our production process, resulting in two types of defects in the release levers on ZIGZAG, ZIGZAG PLUS and ZILLON:
ZIGZAG, ZIGZAG PLUS and ZILLON release levers.
This production variance causes premature wear of the release levers, resulting in slippage that can be observed after a few months of use, or even on new products.
This situation has lead us to three actions:
Check the effectiveness of the upper release lever return spring (1) and the mobility of the lower release lever (2) for ZIGZAG, ZIGZAG PLUS. Repeat the test at least ten times.
The levers should move freely without friction.
If the results of these tests are not satisfactory, immediately stop using your product and return your product by contacting your local after-sales service center with on the contact form. If the release levers work, proceed to the next inspection point
ZILLON: Hang on the lanyard in single mode at a very low height: there should be no slippage. When used in double mode, verify that pressure on the release lever allows smooth and controlled sliding of the rope.
ZIGZAG / ZIGZAG PLUS: perform a function test with your rope (compatible rope diameters: 11.5 to 13 mm). Install the ZIGZAG in double mode. Suspend yourself at a very low height.
When hanging from the ZIGZAG in double mode, there should be no slippage. Verify that pressure on the release lever allows smooth and controlled sliding of the rope.
If the results of these tests are not satisfactory, immediately stop using your product and return your product by contacting your local after-sales service center on the contact form.
If you have any doubt about the results of these tests, contact us via the contact form. These inspection points are in no way a substitute for a complete PPE inspection of your product following the procedure available on Petzl.com.
Serial numbers are indicated on the product:
The test should be performed with your rope (compatible rope diameters: 11.5 to 13 mm). This test is valid for one device/rope combination. If you change the rope, the result of this test may be different (e.g. smaller diameter rope or new rope). Be sure to perform this test each time you change the rope, in accordance with the Instructions for Use.
If you have inspected your product and it does not slip, you can continue to use your product. However, make sure to perform a function test before each use and whenever the rope is changed, in accordance with the Instructions for Use.
Contact your local after-sales service center on the contact form. Choose ”After Sales Service” in the reason for the request.
Your product will be exchanged. Return costs are at our expense.
Because of the defects in the release levers, we have also noted that in use, under certain conditions (repeated loading on the same section of rope, use of a PANTIN-type foot ascender and/or small diameter rope), you may experience more significant and/or more frequent slippage.
In this case, return your product by contacting your local after-sales service center on the contact form.
Yes, there is more slippage if you use small diameter ropes such as FLOW. To limit slippage, you can use a larger diameter rope within the authorized diameter range. Be sure to perform a compatibility test before use.
Any sign of slippage or poor locking may indicate that the device is worn. Be sure to perform a complete inspection of your product by following the PPE inspection procedure.
To date, no injuries have been reported to Petzl. We have only received reports of inconvenience related to slippage.
All products with serial numbers between 18L 0000000 000 and 21G 0000000 000 are affected by the geometry defect of the release levers. For the defect concerning malfunction of the spring effect of the upper release lever, the return rate is 0.025%
If your product’s serial number is between 18L 0000000 000 and 21G 0000000 000 and slips when tested as requested in our information, you have until December 31, 2022 to return your product.
