4X4 Safety Precautions/Tech Tips

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.

WARNING: Do not override or tie down the power switch.

DRESS CONSIDERATIONS: 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, 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 complete visual inspection.

Use only with proper AC voltage power source 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 power cord out of all cutting fluids and water.

AREA EQUIPMENT: Secure work. Whenever possible use clamps, vises, chains and straps to secure pipe.

Make sure the work piece is secured and tool is firmly mounted in pipe; 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.

Use both screws to mount the tool bit. Loose bits are a safety hazard.

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 bare 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 which 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.


Tech Tips...

• Only use a single bit to cut with. While more than one bit can be mounted, the quality of the cut will degrade or cause undue torque loads on the tool.

•Remember, pipe ends are not always square. When starting a new cut, it is likely that the cut will start as an interrupted cut. Feed slowly at first to allow the cutting bit to make full contact with the pipe end (cutting through a full turn) before increasing feed pressure. Feeding the bit into an uneven end at too much speed could damage the tool bit and cause increased tool wear.

• Pipe bevelers cut best when under appropriate load. Too little or too much feed is a matter of feel and will become apparent as you gain experience with the machine. A proper feed rate (feed pressure) is when the cut metal curls off the bit in one continuous "chip." The chip may curl up into a ball and block your view of the cut. Stop the cut and use pliers to clear chips away from the machine (you can back off the feed handle to facilitate chip removal). Remember that the chips are razor sharp. Always use pliers and remove chips with extreme caution. Never use bare hands to clear chips from the machine.

• The optimum feed rate will vary greatly with different wall thicknesses and materials. Experiment to find out what works best for the material being cut.
