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 specific 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 757RSS, Hydraulic Power Supply
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 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 powercutting 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 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 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 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 757RSS, Hydraulic Power Supply
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 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 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.
