Cleaning; Lubrication; Oil System Maintenance; Replacing No. 732 Cutter Wheel - RIDGID 1215 Manual

Cleaning

After each use, empty the threading chips from the chip
tray and wipe out any oil residue. Wipe oil off exposed
surfaces, especially areas of relative motion like the
carriage rails.
If the jaw inserts do not grip and need to be cleaned, use
a wire brush to remove any build up of pipe scale, etc.

Lubrication

On a monthly basis (or more often if needed) lubricate
all exposed moving parts (such as carriage rails, cutter
wheels, cutter feed screw, jaw inserts and pivot points)
with a light lubricating oil. Wipe any excess oil from ex-
posed surfaces.
Clean the lubrication points to remove dirt and prevent
contamination of oil (Figure 16). Fill the lubrication points
with lubricating oil. Press the ball in the lubrication point
to allow the oil to reach bearings.

Oil System Maintenance

Keep oil filter screen clean for sufficient oil flow. Oil filter
screen is located in the bottom of oil reservoir. Loosen
the screw that secures filter to base, remove filter from oil
line and clean (Figure 17). Do not operate machine with
oil filter screen removed.
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. Follow all
local laws and regulations when disposing of oil. Clean
build up from the bottom of the reservoir. Use RIDGID
Thread Cutting Oil for high quality threads and maximum
die life. Oil reservoir will hold approximately 1.5 qt (1.4 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.
