Operation Manual # 02002215
14.3.13When the arm of the PPDT reaches the end of the capture distance, the alarm
will beep.
14.3.14Allow the remaining material to purge from the cylinder and then, if the
machine is equipped with the optional WLD, raise the weight support platform.
14.3.15Rotate the PPDT counter-clockwise so that its arm is toward the rear of the
furnace. This will prevent damage to the arm during cleaning operations.
14.3.16Clean the piston, cylinder and orifice thoroughly as described in Section 16. IT
IS IMPERATIVE THAT THE MACHINE IS CLEANED AFTER EACH TEST.
If no more tests are needed, remove the piston and orifice from the furnace
before turning the MP1200 off to prevent them from being welded in place as
any material left in the barrel hardens.
