Primary Piping System Installation CUTTING AND TAPERING PIPE manual tapering tool has an old-style blade holder, it must be replaced. The correct taper angle is 13/4 degrees for 2", Gutting 3" and 4" pipe sizes. To cut fiberglass pipe, refer to page 3. A NOTE- Cutting operations for fiberglass pipe can LLI IL generate dust or cutting chips that are irritating to the skin, upper respiratorytract, and eyes. Because these materials are irritating, good ventilation for the installation crew should be used to prevent exposure. A nuisance dust breathing filter should be used when working in areas Mere dust will be present. Operators should wear heavy cotton clothing, including long -sleeve shirts, that protect the skin from the dust. Eye protection is required for the tool operator. Tapering The matched taper concept employed by FGS is the key to excellent joint performance. Retract the protective mesh covering on 2" pipe approximately 12" from the end to be tapered. Proper tapering tolerances are factory set. However, it is recommended the tool settings be checked prior to installation of the pipe and fittings. To compensate for wear of the grinding drum, the mandrels can be field adjusted. Refer to the tool operating instructions for field adjustment procedures. The tapering tools will reproduce a field -made taper that inserts into the same bell to a * 118" (3 mm) tolerance when compared to a factory -made tapered spigot. The angle for properly made field tapers for 2'�4' (50 mm -100 mm) diameter pipe should be 13/4 degrees. NOTE: If the There are several power tapering tools available for use with FGS Smith Fibercast piping systems that are not manufactured by FGS. It is the tool operator's responsibility to ensure that the tool being used is reproducing a field -made taper that is within the tolerances of a factory -made tapered spigot. Refer to Bulletin No. F6600 for the correct procedures to verify matching tapered spigot tolerances (factory versus field made). WARNING - Men tapering pipe with a 2000 series power tool, DO NOT rotate pipe with your hand over the end of the pipe as this could result in serious injury. Place both hands firmly around the pipe a minimum of 2" from the end of the pipe and rotate counter clockwise. Keep a firm grip on the pipe at all times and keep moving in a constant motion. If you loosen your grip on the pipe, the grinding drum could grab the pipe and spin it backwards resulting in the pipe being locked up on the tool and possibly causing injury. NOTE: Protect pipe from chain vise damage by placing rubber sections or sleeves (180' sections of pipe cut from the same size pipe being tapered) between the pipe and the chain vise. When using a manual tool and pipe is clamped into a chain vise, extend pipe at least 12 inches (300 mm) beyond chain to prevent oval shaping of the pipe. For short nipples, taper one end of the pipe (or use an existing factory taper) and cut to the desired finished length. Insert the tapered side into a sleeve coupling. Insert into tool and taper per the supplied instructions. M
