D. Procedure
WARNING: THE ELECTRICAL TEST SET-UP USES 115 VAC VOLTAGES. OBEY STANDARD PROCEDURES TO WORK WITH HIGH VOLTAGE.
CAUTION: PLACE THE COMPONENT ON A CLEAN WORKBENCH, IN A DUST-FREE AND MOISTURE-FREE ROOM. HANDLE ALL PARTS CAREFULLY, AND PROTECT THEM AGAINST CORROSION AND IMPACT DAMAGE AFTER DISASSEMBLY.
CAUTION: EXAMINE THE PARTS TO MAKE SURE THAT THEY ARE SERVICEABLE AND HAVE THE CORRECT PART NUMBER. MAKE SURE THAT THE PARTS ARE CLEAN AND THERE IS NO PRESERVATION MATERIAL REMAINING.
CAUTION: ELECTRICAL CONNECTIONS ARE MADE USING THE MINIMUM AMOUNT OF SOLDER (TYPE SN63 PB37) NECESSARY TO EFFECT A CORRECT JOINT. AFTER SOLDERING, BRUSH THE SOLDERED JOINT AND THE SURROUNDING AREA WITH THE SPECIFIED CLEANSER TO REMOVE UNWANTED MATERIALS AND SOLDER. DRY WITH A LOW PRESSURE AIR JET.
CAUTION: WHEN SOLDERING, CONFINE THE HEAT, AS MUCH AS POSSIBLE, TO A LIMITED AREA AT ONE TIME. USE TEMPERATURE CONTROLLED SOLDERING IRONS AND HEAT SHUNTS TO PROTECT THE COMPONENTS FROM THE EFFECTS OF HEAT.

(m) Install the Cover (05-010), the Washers (05-030) and the Screws (05-020). Subtask 21-53-12-820-001-A01
(2) Adjustment of the brake framework of the Motor (03-610B)
(a) Obey the procedure that follows to do the adjustment of the brake framework:
Page 7005
21-53-12 JUN 15/10
1 Deactivate the Brake Framework (apply 28 VDC between the pin T and the pin U of the connector).
2 Measure and record the value E (Ref. to Fig. 7001).
3 Activate the Brake Framework (remove the 28 VDC from the pin T and the pin U of the connector).
4 Make sure that the Value E = 0,15 ± 0,03 mm (0.0059 ± 0.0012 in).
5 If necessary, replace the Washer (05-080) by a Washer (05-081) or (05-082) to get the Value E = 0,15 ± 0,03 mm (0.0059 ± 0.0012 in).
