Maintaining the riveting tool
Caution
Hazard of injury if handled in an improper manner! Servicing,
maintenance and repairs of the riveting tools must be carried
out professionally. On completing this work, there should not be
any more hazard to the operator, if used as per the regulations.
The operator may only carry out the operations mentioned
here.
Bleeding the hydraulic section
It is necessary to bleed the hydraulic system or to refill the hydraulic oil
when:
— oil is leaking from defective O-rings,
— after an oil-change at the time of an overhaul
(either after a maximum of 3 years, or after 2000 working hours).
• Detach the compressed air connection.
Note
If you clamp the riveting tool into a vice, then insert a soft
material in-between (Alu/ wood).
Screw off tension head case to avoid pressure on the hydraulic
rod as otherwise you cannot fill in enough oil (also see pages
17 - 20 “Mount Tension head”).
• Bend the riveting tool carefully towards the front at an angle and fix e.g.
inside a vice (like illustrated in the diagram).
This position makes it possible for enclosed air to escape.
• Unscrew the socket head screw (7) in the hydraulic housing carefully
using the internal hex key SW4.
