SAFETY PRECAUTIONS
WARNING:
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 specific operating instructions.
Do not override the deadman switch on the power unit. Locking down, ob-
structing, or in any way defeating the deadman switch on the power drive unit
may result in serious injury.
DRESS CONSIDERATIONS
Use standard safety equipment. Hard hats, safety shoes, safety harnesses, protec-
tive 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 floors 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 flammable 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 com-
plete 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 fluids 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 muffler. Broken or damaged mufflers can restrict air
flow or cause excessive noise. Use air motors only with a filtered, lubricated and
regulated air supply. Dirty air, low-pressure air or over pressure air will cause mal-
functions, 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 haz-
ard.

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 finish. 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 oper-
ating switches or levers. Do not lay the tool down in a manner that will start the
drive. Do not allow the tool to flip 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 572AC SEVERMASTERTM severs 1/4” to 2” (6.35 mm to 50.80 mm)
diameter tubes and thin wall pipe within the size range.
This machine enhances productivity by incorporation of an Auto-Cycle Tool Module
and Quick Lock Collet Closure.
The Auto-Cycle Tool Module incorporates a cam cycle tool bit feed mechanism,
which automatically returns the tool bit to the home position ready to start the next
cut.
The tool module also allows setting the start and finish cut position to minimize the
cycle time.
The feed increment per revolution is adjustable to match the cutting relative to the
material.
A variable speed motor provides cutting speed control for tool bit life and ID burr
condition.
The Quick Lock Collet Closure mechanism actuates the Collet with a single lever
stroke and provides for simple Collet changes.
Tool bit options are available to minimize the burr on either of the mounting side or
the drop-off side of the sever line and in different edge widths to match the tube wall
thicknesses.
The Model 572AC also incorporates mounting features to allow use of an SQM-1AC
Tube Squaring Module for optimum burr free ends.
Model 572AC SEVERMASTERTM System, consists of the mainframe with the Quick
Lock Collet Closure, Auto-Cycle Tool Module with adjustable depth of feed from
.001” to .005” (.02 mm to .13 mm) per revolution, drive motor, wrench kit, operator's
manual and carrying case.

MAINTENANCE
IN GENERAL
All components should be cleaned and coated with a light film of oil prior to use.
Use a clean, non-detergent oil, preferably SAE 10 (90 SSU) or lighter.
The air supply for the Model 572AC (pneumatic drive) should include an adequate
filter, regulator and lubricator (FRL).
The air supply for the Model 572AC is operated in such a manner that the tool
holder collects debris while cutting, the tool holder and the slides should be cleaned
after each cutting operation.
Tool life may be severely shortened, unless chips and/or other debris that have been
deposited on the cutting head during the machining operation are removed.
RECOMMENDED MAINTENANCE SHCEDULE
Daily maintenance when the unit is in operation includes wiping the unit down and
spraying with rust preventative under severe humidity conditions. Visually inspect for
loose screws, missing screws, damage, etc.
After every 20 hours of actual operation, lubricate the male and female tool holder
slides.
After every 40 hours of actual operation, thoroughly clean and lubricate main gear,
drive gear, male and female tool slides, and tripper bracket assembly.
If the Model 572AC is to be stored or if it will remain out of service for a significant
period of time (30 days or more), it should be thoroughly cleaned lubricated and
sprayed with a rust preventative prior to storage.
TOOL HOLDER MAINTENANCE
Clean the slide rails, the tool holder, and the feed components.
Inspect these parts for damage and replace as required.
Lubricate and reassemble.

Adjust the adjustable slide rail to provide a firm, but not excessive pressure on the
tool holder.
The slide rails must be over tightened to squeeze the oil into a thin film against the
male and female surfaces of the slide rails.
Reset for proper operation.
TRIPPER BRACKET ASSEMBLY LUBRICATION AND ADJUSTMENT
Back off the half-dog set screw until it disengages from the tripper shaft.
Remove the tripper shaft assembly from the bracket and clean off all of the old
lubrication.
Apply fresh lubrication to the tripper shaft assembly and reinstall it in the bracket.
Screw in the half-dog set screw until it locates itself in the slot on the tripper shaft.
Try turning the tripper shaft assembly to ensure that the set screw is in the slot of the
tripper shaft assembly and is preventing it from rotating.
LUBRICANT RECOMMENDATIONS
The drive gears require a heavy duty grease such as “Chevron Ultra Duty Grease,
ER, NLGI2”.
The slide rails and tool holder require a light oil such as SAE 10 light machine oil.
The tripper bracket assembly also requires a SAE 10 light machine oil for normal
conditions and under dusty conditions a silicone, graphite or molybdenum disulfide
‘dry’ lubricant.
A light film of all-purpose grease may be used, but it must be used, but it must be
checked for grit contamination frequently.
