238-P Soil Pipe Cutter
Tool Set-Up and
Operation
WARNING
Follow set up and operating instructions
to reduce the risk of serious injury from
striking or impact injuries and other
causes and prevent machine damage.
Keep others out of work area while cut-
ting. Stand clear of the pipe. Cutting can
cause pieces of pipe to be thrown with
considerable force. This can cause strik-
ing injuries, eye injuries, or other seri-
ous personal injury.
Always wear eye protection to protect
your eyes against dirt and other foreign
objects.
Keep your fingers and hands away from
the cutting chain during the cutting cycle.
They can be crushed, fractured or ampu-
tated if they become caught between
the pipe and cutter or other objects.
1. Check work area for:
• Adequate lighting
• Clear, level, stable place to work.
2. Inspect the pipe to be cut. Determine the
size and type of material. If cutting pipe
that is already in service, determine the
pipe contents.
3. Determine the correct soil pipe cutter for
the application.
See the information in
the Specification section. Other pipe cut-
ters can be found in the RIDGID Catalog
at www.RIDGID.com
4. Make sure that the soil pipe cutter has
been properly inspected.
5. Prepare the pipe to be cut.
• Take any appropriate steps required
to drain the pipe and/or deal with any
potential spillage.
• Clean mud or corrosion off of the pipe.
Excessive corrosion or mud can cause
poor quality cuts and damage cutter
wheels.
• Make sure there is enough room to get
the chain around the pipe. Approxi mate -

" (38 mm) of clearance is needed
the chain can be cleaned with a wire
brush. This aids in inspection and helps
prevent the tool from slipping from your
grip during use.
2. Inspect the soil pipe cutter for the follow-
ing items:
• Proper assembly and completeness
• Broken, cracked, missing, bent or bind-
ing parts
• Excessive corrosion and wear
• Smooth, free movement of screws,
chain and linkages
• Presence and readability of the warn-
ing label (See Figure 1.)
3. Inspect the chain for signs of overload or
other damage. There should be no signif-
icant gaps between the plates of the
chain. If there are large gaps between
the links of the chain or other damage,
the chain should be replaced. Check the
cutter wheels for wear and damage.
Worn and damaged cutter wheels in-
crease cut force and can cause poor
quality cuts.
4. Inspect the impact tool and any other
equipment being used as directed in their
instructions.
5. If any problems are found, do not use
the soil pipe cutter until corrected.
6. If needed, lubricate pivot points and the
chain with a light lubricating oil. Wipe any
excess oil off.
7. Yearly (or more often under heavy use),
disassemble the cutter by turning the
hand flange clockwise (left hand thread).
Remove the C-washer and unscrew the
feedscrew from the cutter. Clean the feed-
screw and washers and apply a good
quality extreme pressure (EP designa-
tion) grease to points of relative motion
when reassembling.
