Hydraulic system for blind riveting, large pressure booster 3-8060
Installation aid: Non-return bleeder valve E9-7 (accessory)
- Close both throttle silencers 3-8082 down to one turn on the valve terminal.
- Switch on master switch and select "MAN" menu.
- Reduce operating pressure to 4 bar at pressure reducer valve 1-8002, check pressure at
pressure gauge 1-8046.
- To set piston unit 2-6190 to its starting position, insert a blind rivet into spreader nosepiece
2-80.
- Press "ON" button.
- Remove rear bleeder screw 2-28a on riveting gun and screw in non-return bleeder valve E9-
7. (Connect a bleeder hose with 8 mm outside diameter to the valve to drain off and collect
the excess hydraulic oil.)
To facilitate bleeding, the riveting gun should be positioned such that the
hose assembly is on an upward incline from the supply unit to the riveting
gun.
- Remove screw plug (see figure on right) from housing and re-
fill oil reservoir of pressure booster 3-8060 with hydraulic oil
through the opening as required. The hydraulic system fills up
by alternately activating the "stroke position" function. The oil
level must not drop below the minimum mark. 6 to 8 refilling
operations are generally required.
- The refilling procedure is completed when bubble-free hy-
draulic oil flows out of the bleeder hose.
- Lower the riveting gun to the level of the oil reservoir of the
pressure booster. Unscrew non-return bleeder valve from the
riveting gun.
Before screwing in the bleeder screw with seal, make sure that the oil level
is visible at the bleeder hole. The oil level can be raised by further lowering
the riveting gun.
- Screw in bleeder screw with seal.
