NOTE : Make sure that you always keep the reflectors or mirrors of the infrared generator clean, to make sure that heating is constant.
-Put the generator selector in Auto position.
-Adjust the generator to agree with the generator type and the sleeve.
-Choose the gun and the reflector to agree with the solder sleeve.
-Push the reflector trigger and engage the wires and the slevee in the reflector.
-Make sure that the assembly is in the correct position.
-Turn the soldering on to the infrared source.
-Push the trigger of the infrared gun to start. The gun stops automatically at the end of the cycle.

R R ___________________________________________________________GENERAL REQUIREMENTS FOR CONTACT INSERTION/EXTRACTION TOOLS _________________________DESCRIPTION AND OPERATION
R R _______1. General
R R This topic gives the requirements and the processes to insert/extract the removable contacts used on aircraft.
R
R R R __________2. Definition (Ref. Fig. 001) The removable contacts have to be correctly positioned and locked in connecting elements to secure reliable electrical connections.
R ______________________________3. Insertion of Contact with Tool (Ref. Fig. 002) Select the tool to suit the type and size of contact (Ref. 20-48-XX).
____NOTE : To facilitate insertion of the contacts in the modules/connectors and to improve the check made on the locking of each contacts, twisted wires must be untwisted over a lenght of 60 mm (2.3622 in.) before connecting to connectors or modules.
For a plastic or metal tool, pen type : - take the colored end, - with your thumb, slide the cable into the opening, - apply slight tension so that the collar of the contact bears on the front of the tool, - stop all relative movement by gripping the cable between your thumb and the anti-slip portion of the tool. For other tools :
- install the wired contact in the tool, - position the contact in line with the cavity, - push forward. When the collar passes through the clip, a small click may be heard and the locking felt, - free the cable by releasing the pressure, - remove the tool from the cavity by pulling rearwards ; the tool slides over the
