Correct adjustment of the screed before paving begins prevents unnecessary wear.
Click on the gallery to see the procedures for the various screed components.
The planing angle must be correctly set on both the inner and outer edges of the extending screed.
After setting the planing angle, please tighten the clamping screw for height adjustment again. Now check the settings again.
Before carrying out the adjustment of the adjusting spindle, the play of the threaded bush (5) should be checked with tightened locking nuts.
Always adjust all four spindles of each extending screed.
The tamper must always have the same stroke across the entire paving width. The stroke can be altered by twisting the eccentric bush on the drive shaft of the tamper. This can be carried out easily from behind when the paver is being moved from one section to the next. In contrast, adjusting the lower reversal point of the tamper bar in relation to the screed plate, takes a little more time and effort. First of all, the metering gates must be removed to access the bolts that need to be removed from all the shaft mounting brackets. After removal of the locking nut (2), the tamper height can be altered with the bolt (1). The height to be set depends on the stroke setting of the tamper.
The tamper should be set flush with the screed plate at a stroke of 2 mm (manual check by touch).
The tamper (3) must be set to rest lightly over the entire length of the wear strip (1). Then adjust the spring steel bar (2) on the metering gate by means of the screw (4) from the rear of the screed until there is a gap of 0.5 to 1 mm between the tamper and the spring steel bar. By removing screws (6) and fitting various small shims (5), the metering gate should be aligned so that the spring steel bar (2) is at least parallel to the tamper or is preferably slightly inclined towards the front.
Finally, recheck the gap between the tamper and the spring steel bar and correct it if necessary.
Screed side plate height adjustment is a function often used during the paving process. As a user, you know from experience that this function is often needed when paving, for instance, along kerbs with high or low kerbstones or along gutters.
