1224 Threading Machine
Replace thread cutting oil when it becomes dirty or con-
taminated. To drain the oil, position a container under
drain plug at end of reservoir and remove plug. Clean
build up from the bottom of the reservoir. Use RIDGID
Thread Cutting Oil for high quality threads and maxi-
mum die life. Reservoir in the base will hold approxi-
mately 5 qt (4,7 l) of thread cutting oil.
The oil pump should self-prime if the system is clean. If it
does not, this indicates that the pump is worn and should
be serviced. Do not attempt to prime the pump.
