2-3, BRAKE ADJUSTMENT
NOTE: The explanation and figure in this paragraph are for the left
side brake, similar checks and adjustments are applicable
for the right side one.
1, Adjust by moving the brake band bracket in either direction
(arrow (A)) so that the reel motor chassis is in parallel with the
brake arm, and so that the brake band makes proper clearance
i equally all around the reel table base.
i C, €) so that, when the plunger is pushed in the direction of the
] solenoid housing, the reel table base is not rubbed by the brake
i band and is properly spaced.

2-4. BRAKE TORQUE MEASUREMENT
1, Place an empty 7" reel, connected to a spring scale by a string,
on the reel table,
2. Pull the scale away from the reel and read the scale indication
only when the reel table is steady motion.
3. Do steps 1 and 2 for each measuring condition, (A) through
(D) in Fig. 2-3.
4. The values are as chart in Fig. 2-3.
A B c¢ D
1.2 to 1.7kg-em (17 to 240z-inch)
0.6kg-cm (8.302-inch) or less
+ Forward direction (B) (C)
* Reverse direction (A) (D)
Left/right deviation
0.2kg-cm (2.802-inch) or less
NOTES: 1. The reverse direction values are reference.
2. The specification of left/right deviation only
applies for forward direction torques.
Torque calculating formulas:
(1) Torque (in g-cm or oz-inch)
= Force or Weight (in g or oz) x Radius (in cm or inch)
(2) Conversion of g-cm to oz-inch:
g-cm x 0.0139 = oz-inch
