5.11 Crimping / pressing 5
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.
WARNING
Risk of injury due to misaligned adapter jaws and crimping ring. The adapter jaws and/or the crimping
ring can fly off like projectiles and lead to serious injury to the user or a bystander.
▶ The adapter jaws and the crimping ring must be correctly aligned throughout the entire crimping /
pressing operation.
CAUTION
Damage to property due to incorrect handling! Incorrect handling can result in damage to the pressing
tool and/or the pressing rings.
▶
Before starting work, make sure that pressing rings, adapter jaws/pressing jaws and rolling actuator (if
present) are dust-free and well lubricated.
▶ Before starting work, lubricate pressing rings, adapter jaws/pressing jaws and rolling actuator (if present)
with "lubricant and corrosion-inhibiting spray" (#308976).
▶ Comply with the original operating instructions of the manufacturer for the pressing rings.
In cold weather the hydraulic oil can thicken and slow the pressing operation. Perform 5 to 10 empty
pressing operations to heat up the pressing tool.
1. Press and hold the control switch until the crimping / pressing jaws are completely closed.
2. When using a crimping / pressing ring, bring the product with the adapter jaws into position on the
crimping / pressing ring and carry out the crimping / pressing 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.
