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 the pressing rings are dust-free.
▶ Before starting work, lubricate the pressing rings and - if present - the rolling actuator with lubricant and
corrosion-inhibiting spray (#308976).
▶ Comply with the original operating instructions of the manufacturer.
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.
In cold weather the hydraulic oil can thicken and slow the crimping / pressing operation. Perform 5 to
10 empty crimping / pressing operations to heat up the crimping / pressing tool.
1. Insert the crimping / pressing jaws. → page 7
2. Squeeze the legs of the pressing jaws together.
▶ The pressing jaw opens.
3. Enclose the fitting to be installed in the pressing jaw.
4. Press and hold down the control switch until the piston retracts.
▶ The pressing operation is completed successfully.
