of 0.3 - 0.5 mm

between the head of the screw

and the tongue of the brake lever in stop position.

The brake lever should be slidable in direction of the slot (i. e. to suit the diam

page 2. The lever pos. 25 can be adjusted by setting the lock nuts on tie rod pos. 24. C

orrect adjustment is

obtained in pos. stop if the motor pulley is free of the rubber rim

of the flywheel and a brake action of the fly-

wheel takes place sim

is

adjusted by bending the free end of the brake lever.

Tape D

rive (figures 1 and 2)

The center of tape should have a distance of 22.25 m

m from

the top edge of the chassis with the tape

running in the center of the tape reels, thereby the distance between top edge of chassis and low

er edgeof tape guide post pos. 27 m

ay be approx. 19.12 mm

.

The recording head pos. 28 is m

ounted in a distance of 2.5 + 0.1 m

m before the connection line betw

eenthe tw

o outer tape guide posts. After adjustm

ent tighten grub screw pos. 29 w

hich is tightened by a coun-ter nut. T

he gap of the recording head may overlap the top edge of the tape 0-0.1 m

m. S

mall corrections

can be done by means of the tape guide posts.

The gap of the erase head pos. 30 should be m

ounted 0.3 - 0.5 mm

over the tape center. This m

easureis

referred to the tape center to avoid erasing on track 2 which could be caused by the stray field of the

magnet.

For adjustm

ent use a gauge made by yourself. T

his gauge is made of a thin strip of hard paper 6.25 m

mbroad or a sim

ilar material w

hich does not damage the gap of the head. O

nplace of the erase head make

a suitable cutout, the lower edge of w

hich may be 0.3 m

djust the erase head in record-ing position that it

is moved ±

2° max. referred to the adjustm

ent of 12° as per fig. 1 which can be caused

by moving air w

hen stopping. The erase head is located in

its adjusted position by means of counter nuts

pos. 31.

The driving chain can be stretched a sm

all amount by setting the adjustable boss buffer pos. 32.

The stop bolt pos. 34 on the slider pos. 33 serves for lifting the pressure roller lever pos. 35 in position

stop and rewind. A

djust the stop bolt in positions playback or recordinguntil the distance betw

een stopbolt and the pressure roller lever reads 0.2 - 0.3 m

arked "M".

The tape pull reads in positions playback or recording ?.

The screw

s pos. 37 can be used to set the pressure roller absolutely vertically in accordance to the pos. ofthe capstan of the flyw

heel. The screw

with pressure spring sreves for stabilizing and should be secured after

the adjustment has been finished.

The screw

pos. 38 serves for the vertical adjustment of the gap of the recording head w
