SAFETY PRECAUTIONS
IN GENERAL
When using rotating head cutting equipment, basic safety precautions should always
be followed to reduce the risk of personal injury.
Operate this tool only in accordance with specic operating instructions.
Do not override the deadman switch on the power unit. Locking down, ob-
WARNING:
DRESS CONSIDERATIONS
structing, or in any way defeating the deadman switch on the power drive unit
may result in serious injury.
Model 642SB Low Prole Clamshell
Use standard safety equipment. Hard hats, safety shoes, safety harnesses, protective clothes, and other safety devices should always be used when appropriate.
Use safety glasses. Do not operate cutting tools without eye protection.
Dress properly. Do not wear loose clothing or jewelry. They can be caught in rotat-
ing and moving parts. Avoid slippery oors or wear nonskid footwear. If you have
long hair, wear protective hair covering to contain it.
WORK AREA
Keep the work area clean. Cluttered work areas and benches invite injuries.
Consider the work area environment. Keep the area well lit. Keep electrical cords,
cables, rags, rigging straps, and etc. clear of rotating equipment. Do not use power-
cutting tools in the presence of ammable liquids and gasses.
Keep visitors away. Do not let visitors or untrained personnel at or near operating
tools. Enforce eye protection requirements for all observers.
Do not over reach. Keep proper footing at all times.
Stay alert. Watch what you are doing. Use common sense. Do not operate tools
when you are tired.

TOOL CARE
Maintain tools with care. Keep tools in good operating condition. Sharp tool bits
perform better and safer than dull tool bits. Well maintained tools function properly
when needed.
Check for damaged parts. If a tool has malfunctioned, been dropped or hit, it must
be checked for damage. Run no-load tests and feed function checks. Do a complete visual inspection.
Electric motors. Use only with proper AC voltage power sources and observe all
normal electric shock hazard procedures.
Do not abuse power and control cords. Pulling or running over cords and cables can
result in electrical shock hazards and malfunctions. Keep control and power cords
out of all cutting uids and water.
Hydraulic drives. Observe proper procedures for electrically driven power sources.
Avoid damage to hydraulic lines. Keep quick-disconnects clean. Grit contamination
causes malfunctions.
Air tools. Check the exhaust mufer. Broken or damaged mufers can restrict air
ow or cause excessive noise. Use air motors only with a ltered, lubricated and
regulated air supply. Dirty air, low-pressure air or over pressure air will cause malfunctions, including delayed starting.
AREA EQUIPMENT
Secure work. Whenever possible use clamps, vises, chains and straps to secure
pipe.
Make sure the tool is secured; it is safer to have both hands free to operate the tool.
TOOL USE
Use the right tool and tool bit for the job. Do not use a tool, which is incorrect for the
job you are doing.
Keep the tool bits fully engaged in the tool bit holders. Loose bits are a safety hazard.

Model 642SB Low Prole Clamshell
Disconnect power supply during setup and maintenance. Use all ‘Stop’ or Shut off’
features available when changing or adjusting tool bits, maintaining the tool, or when
the tool is not in use.
Remove adjusting keys and wrenches before applying power to the equipment. Develop a habit of checking the tool before turning it on to make sure that all keys and
wrenches have been removed.
Do not force tools. Tools and tool bits function better and safer when used at the
feed and speed rate for which they were designed.
Do not reach into rotating equipment. Do not reach into the rotating head stock to
clear chips, to make adjustments, or to check surface nish. A machine designed to
cut steel will not stop for a hand or an arm.
Handle chips with care. Chips have very sharp edges and are hot. Do not try to pull
chips apart with your hands; they are very tough.
Avoid unintentional starts. Do not carry or handle tools with your hand on the operating switches or levers. Do not lay the tool down in a manner that will start the
drive. Do not allow the tool to ip around or move when adjusting or changing tool
bits.
Store idle tools properly. Disconnect tools from the power source and store in a safe
place. Remove tool bits for safe handling of the tool.

GENERAL DESCRIPTION
The Model 642SB Low-Prole Clamshell is a split-frame pipe lathe designed for
severing and beveling in-line pipe with a minimum range of 38” through 42” pipe with
minimal radial and axial clearance.
Using Standard Tool Blocks the Model 642SB may be congured to perform the
following operations:
Sever in-line pipe.
Sever and bevel in-line pipe.
Sever and double bevel in-line pipe.
DESIGN AND OPERATING FEATURES
The easily adjustable precision bearing surfaces pre-load and stabilize the rotating
head to provide long life, low maintenance, stability, and precision.
The Clamshell splits into two halves for mounting on closed loop systems.
All parts are secured to the two halves, thus avoiding the loss of parts and at the
same time providing maximum ease of handling.
The Clamshell is equipped with Adjustable Clamping Pads and Jackscrews for outof-round pipe conditions.
Dual Tool Blocks with Auto-feed Sprockets and Adjustable Slides provide maximum
maintainability, life, and operator safety, with a minimum of operator training.
The Auto-feed Sprockets provide .004” (.10 mm) of radial feed per revolution of the
Headstock for a controlled depth of cut.
The drive gears and bearing surfaces are covered for operator safety and are
shielded to provide protection from dust and chips.
The operator’s controls are located away from the rotating Headstock for the
operator’s safety.

TOOL HOLDER ADJUSTMENT
Loosen the Hold-down Screws on the Adjustable Slide Rail.
Run the Tool Holder to the most outward position.
Using the Adjustment Set Screws, apply a light force to the side of the Adjustable
Slide Rail so that it is in positive contact with the Tool Holder.
Adjust only those screws, which bear directly in line with the Tool Holder.
Tighten the Hold down Screws to about 12 to 24 in-lbs. (1.4 to 2.7 N-m). (Finger
tight using a hex key)
Using the Spanner Wrench, run the Tool Holder to the inward most position.
Note any changes in the feed pressure.
Adjust the remaining Adjustment Set Screws so that the Tool Holder has a smooth,
even feel.
Run the Tool Holder the full length of the Slide Rail.
