In the presenceof a 12” record, the upward movement of the sensing lever (154) as released by the control cam (128)is limited.

Thisskating force, as t is called, has the effect that thestylus exerts more pressure on the inside edgethan on the outside edge of the record groove.The skating force is a function of the stylus pressure, the stylus tip radius and the frictional conditions existing between the stylus and the record.The antiskating adjustment is made by adjustingthe stylus force, This is done by means of a springin axial alignment with the pick-up arm. The antiskatingdevice is controlled by means of a controlknob. Corrections are needed where differentstylus tip radii, elliptical needles or wet playbackare used.

Themounting gauge (26) supplied with turntableswithout pick-up makes it possible to check the pickup for correct position.Mounting pick-ups on the pick-up head(only applicable to units without pick-up)To mount a pick-up, please proceed as follows:1) Turn the rotary knob for the tracking angle adjustment (6) to position I Then mount the pickup by means of the screws (22) and spacerrollers included in the accessories so on thepick-up retaining plate (27) that the needle of thepick-up is exactly in the center of the two intersecting lines of the mounting gauge (26) thathas been slipped over the guide grooves of thepick-up head. In this position, the needle shouldjust touch the inside surface of the mountinggauge. Choose the size of the screws and of thespacer rollers as required for the pick-up.2) Loosen the retaining screws (22) of the pick-upup once more a little and move the pick-up sidewardsuntil the needle agrees with the longitudinal line. Tighten the retaining screws again.3) For the longitudinal movement of the pick-up,loosen the screw (24) and shift the pick-up untilthe needle coincides exactly with the cross-lineof the two intersecting lines on the mountinggauge (26). Tighten the screw again.The pick-up is now accurately adjusted and youhave the guarantee that the needle will always landin the starting groove of the record in automaticoperation.The slide-in pick-up head is equipped with a 5-poleconnector. Both the two chassis connections of thechannels and also the grounds of the pick-up canbe separatelyconnected, In the case of a regularmodel, I, e. when the grounds in the pick-up headis connected to a chassis pin the leads (25) shouldbe connected as followsredwhtegreenbluechanneleft-hand channelright-hand ground= left-hand groundTracking checkTo prevent geometric playback errors, the horizontal ditance of the needle tip must also be correctlyadjusted. In the PE 2020 pick-up arm this is thecase when the pick-up needle coincides with theintersecting lines of the mounting gauge. If thepick-up is installed by the customer, adjustment tothe optimum conditions is possible.

While holding the tonearm in place by hand push up from theunderside of the chassis on the lift rod and ovserve thespeed and smoothness of the descent of the stylus. If thedescent is erractic (slow then fast) the silicone grease isunevenly distributed over the lift rod. If the descent istoo fast it is insufficently coated, if too slow there istoo much. The recommended speed of descent is approximately5 to 6 seconds.13. Reassemble the turntable reversign the dissassembly procedures.NOTE:Lock nut (item 162) adjusts the tonearm height in the automaticspindle in place, cycle the turntable by hand to the point wherethe tonearm is moving from the arm rest to the turntable platter.Adjust the lock nut (item 162) until the distance from the topof the chassis to the top of the tonearm head assembly measuresbetween 70mm to 72mm for the PE 2020 and PE 2040 or 65mm to 67mmfor the PE 2018 and PE 2035 and PE-2038,NOTE:When the tonearm is locked in place on the arm rest the eccentricscrew adjustment for the toriearrn set-down point located on topof the tonearm locator segment (item 184) should be visablethrough the hole in the top of the chassis.
