▶ If the piston does not retract after the pressing operation, press the reset button for manual retraction.
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 flying fragments! Flying fragments present a risk of injury to the eyes and body.
▶ Wear eye protection and protective gloves.
▶ Use suitable connecting material in combination with the correct pressing rings and pressing / adapter
jaws.
▶ Before and during the pressing operation, make sure that the pressing rings and pressing / adapter jaws
are correctly positioned.
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 8
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.
