6. Adjusting the WST 20/82
The hexagon socket head wrench (2) needed for adjusting all
the parameters is integrated in the handle of the Wire
Stripper and is removed to the rear when required.
Using the Universal Knife
Matching to the exact diameter of the conductor is perfor-
med using the height stop bolt (10). The knife play to the
fixed heater element can be adjusted axially and radially
after loosening the bolts (3 and 4) on both sides of the hand-
le. Any parallel offset to the axis of the heater element can
be compensated by alternate loosening and tightening of the
bolts (5 and 6).
Length Stop
The length stop (8) can be adjusted to the maximum strip-
ping length of 30 mm by applying pressure to the pan head
bolt (7) and sliding. The length stop is locked by releasing the
pan head bolt and can be fixed in place by tightening the pan
head bolt.
Changing the Knives
To change the knives, the hexagon socket head bolts (11) on
the heater elements are removed. During this process the
heater elements are prevented from turning using the open
ended spanner (14). When positioning the knives, it is to be
ensured that the teeth on the knives and the heater elements
interlock. Prior to assembly the fixing bolts (11) are to be wet
with anti-locking compound.
Maintenance and Care
Clean the knives, even if only lightly soiled, at least once per
working day using the brass wire brush supplied, clean the
knives when they are warm.
