Crimping / pressing

WARNING
Danger! Risk of causing gas leakage when carrying out crimping / pressing work on parts of a gas supply
network!
▶ Never carry out crimping / pressing work on parts of a gas supply network unless express approval has
been given by the system supplier for use of this tool in conjunction with specially tested and approved
fittings.
1. Press and hold the control switch until the crimping / pressing jaws are completely closed.
2. When using a crimping ring, bring the product with the adapter jaws into position on the crimping ring
and carry out the crimping operation.
In order to achieve a tight, durable crimped / pressed joint, it is essential that the crimping / pressing
jaws reach the fully closed position, thus indicating completion of the crimping / pressing operation.
If the crimping / pressing operation is ended prematurely, the fitting must be removed or, if
possible, recrimped / repressed.
