will rest loosely on the blade holder until it is locked into place using the supplied alien screws. The two alien screws should now be positioned so that each makes LIGHT contact with the bearing plate (See Figure 2.2.1). NOTE: The aIlen screws only prevent the blade holder from opening during use. The tool is now prepared to remove ("scarf") the resin gloss from the ends of the containment pipe. After re- moving the gauge, insert the tool into the pipe to be scarfed until the point of the blade just touches the end of the pipe. Note: The tool must be rotated in the same direction the wide side of the blade faces. Advance the tool in approximately 1/4 -inch (6 mm) increments after each revolution. Continue the operation until the resin gloss has been removed for a mini- mum length of 3 inches (75mm). An alternate method to prepare pipe ends is to sand with 30-40 grit sand paper or emery cloth to remove all surface gloss. Belt sanders, power grinders, or a coarse -cut flat file may also be used. The sanded length must be a minimum of 3 inches (75mm). Note: Sanded pipe ends must always fit snugly into the socket of the fit- ting. See Figure 2.2.2. 2.2.3 Pipe assembly The containment pipe must be posi- tioned over the product pipe before bonding the product pipe. Pre-instal- lation`of the secondary containment pipe (only) is best accomplished at the same time the product pipe is dry - fitted together. This will speed up installation and prevent unnecessary delays. Where possible, temporarily place containment fitting halves around the product fittings. This measure will help prevent foreign material from entering the containment pipe. See Figure 2.2.3. The containment fittings should be installed and the containment system 1btested after the product piping system has been tested.
