Dual C 810 - Fast Rewind Adjustment; Record Lever Adjustment; Head Adjustment; Cleaning and Lubrication

Fig. 11
10. Fast rewind
There must be a minimum clearance of 0.2 mm between the
right winding gear 156 and the coupling pulley 143. if neces-
sary, the lug K on the head mounting plate 107 should be
bent slightly (refer to figure 6).
11. Record lever
The record lever should be adjusted in such a way that, when
the record button is depressed , the record/playback switch $ 1
rests against the stop. This may be adjusted by bending the
record lever.
12. Record/playback head, erase head
When replacing the record/playback head 103, please note
the following prior adjustment process.
Place the record/playback head 103 together with the leaf
spring onto the head mount. Then, by means of the sleeves
and machine screws Z, it should be secured so that the tape
guides B are in line with the tape guides on the head mount
B 1 and those on the erase head B 2 (fig. 12). Final adjust-
ment should be undertaken in the manner described in the
section ‘electrical alignment’.

13, Cleaning/lubrication
Always clean the unit when servicing it or repairing it. In
order for the unit to function properly, the record/playback
head 103, the erase head 102, the pinch roller 128 and the
capstan should always be spotlesly clean. These parts are best
cleaned with a cotton cloth or cotton bud soaked in methyla-
ted spirit. On no account should metal objects be used. The
surface of the head should never be touched with bare fingers.
Atl bearing and sliding parts are adequately lubricated at the
works. Re-lubrication is not normally required for several
years, since most important parts are provided with oil
reservoirs. The motor bearings are designed as tong life oil
reservoirs and therefore require no lubrication.
