Place the deck in reverse (forward) play mode.
Using a steady, smooth motion, pull against the motor torque
to draw the scale away from the reel.
After making sure that the reel motion is smooth (the string
should not be rubbing against the reel flanges), note the value in-
dicated on the scale.
The proper values are given in Fig. 2-5.
If necessary, adjust the slider of resistor (R802) until the proper
torque values in both forward and reverse play modes are ob-
tained. See Fig. 2-6.

. Hold the right tension arm up using a rubber band, string, etc.
. Place the deck in the forward play mode without threading any
tape.
. Attach a spring scale to the pinch roller as shown in Fig. 2-7.
. Pull the pinch roller away from the capstan shaft (on a plane in-
tersecting the center of the capstan shaft and the pinch roller)
until the capstan shaft and the pinch roller are separated.
. Ease pressure on the scale until the pinch roller just begins to
turn. The scale should then read 1.5 kg to 1.7 kg (3.31 Ibs to
3.75 Ibs),
. By pressing the DIRECTION switch, change play mode to reverse
direction and measure in the same way as previously described.
Specification is the same as that for forward play mode,
