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,
WARNING:
DRESS CONSIDERATIONS
obstructing, or in any way defeating the deadman switch on the power drive
unit may result in serious injury.
Model 620SB Low Prole Clamshell, Hyd.
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
rotating 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. 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 620SB Low Prole Clamshell, Hyd.
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 our 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 620SB Low-Prole Clamshell (P/N 01-1147) is a split-frame pipe lathe
designed for severing and beveling in-line pipe with a minimum range of 16” through
20” pipe with minimal radial and axial clearance.
Using standard Tool Blocks the Model 620SB 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
out-of-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 sealed
to provide protection from dust and chips.
The operator’s controls are located away from the rotating Headstock for the
operator’s safety.
A modular design concept provides quick, easy maintenance and maximum
versatility in the drive and tooling options.
Two detachable Hydraulic Motors provide maximum handling ease and low axial
clearance.
