Tools for the international market are also available: Model 2100-1 and Model 1 2102-1. P„ 4. If the power tools are not ' available,a manual tapering tool kit from Smith Fibercast may be used.The 1"-6"Tool (Bulletin F6600)is a hand- held tool that can be adapt- ed for power when a large number of tapers is neces- sary. Proper tapering tolerances are factory set.However,it is recommended the tool settings be checked prior to installa- tion 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 in- serts into the same bell to a t 1f8"(3 mm)tolerance when com- pared to a factory-made tapered spigot. The angle for properly made field tapers for 2"-4"(50 mm-100 mm)diameter pipe should be 13k degrees. NOTE: If the manual tapering tool has an old-style blade holder,it must be replaced. The correct ta- per angle is 13k degrees for 2",3",and 4"pipe sizes. RED THREAD IIA Pipe & Fittings — 4
