General Safety Rules

Warning! Read and understand all instructions. Failure to follow all instructions listed below may result in electric shock, fire, or serious personal injury.
PLEASE SAVE THESE INSTRUCTIONS!

Work Area Safety
Keep work area clean and well-lit. Cluttered or dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such as in the presence of flam-mable liquids, gases or dust. Power tools create sparks that may ignite dust or fumes. Keep children and bystanders away while operating a powrer tool. Distractions can cause misuse of a power tool.

Electrical Safety
Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of damage or electric shock.

Personal Safety

• Always wear eye protection. Use this tool with enough space to prevent chips from hitting other workers in the same area.
• Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.
• Use personal protective equipment. Always wear eye protection. Protective equip-ment such as dust masks, non-skid safety shoes, hard hats, or hearing protection used for appropriate conditions will reduce personal injuries.
• Prevent unintentional starting. Ensure that the switch is in the off-position before connecting to a power source. Do not pick up or carry the tool with your finger on the power button.
• Remove any adjusting key or wrench before turning the power tool on. If a wrench or key tool is left attached to the power tool’s rotating parts, this may result in per-sonal injury.
• Do not overreach. Keep proper footing and balance at all times to better control the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing, and gloves away from moving parts. An operator with loose clothes, jewelry, or long hair can easily be caught in moving parts of this tool.
• A device has been provided for the collection of dust and chips. Please ensure it is connected and properly used. The use of dust and chip collection can reduce hazards related to debr3is.
• Keep fingers and body parts away from the blade opening.

Power Tool Use and Care

• Do not force the power tool. Instead, use the correct tool for your specific application. The right power tool will do the job better and safer at the rate it was designed.
• Do not use the power tool if the switch does not turn on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
• Disconnect the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
• Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool.
• Power tools are dangerous in the hands of untrained users.
• Maintain your power tools. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Remember, poorly maintained power tools cause many accidents.
• Keep cutting blades sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
• Use the power tool, accessories, and blades according to these instructions, take into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

The primary design is flush cutting or free cutting reinforcing bars, coil rods, and all-threaded rods used in the construction industry. Ap-plication the Cutting Edge Saw can be used for are as follows: 3/8” to 3/4“ (or 10 mm to 20 mm) grade 60 rebar (reinforcing bars), up to ½” I.D pipe, ¾” O.D. copper water pipe, ¾” O.D. tubing, 1/2” conduit, ¾” square steel tubing & bar, and up to 7/8” O.D. all- threaded or coil rod. Use and Storage – The user is required to be thoroughly familiar with the saw, the cut-ting blades, battery care and storage procedures upon completion of use.

Specifications
This power tool is a multipurpose saw with an enclosed guard and flush cutting capabilities. The specifications of the Cutting Edge Saw™ are as follows.

Standard Blade
(Best for Ferrous Metals)
This tool is supplied with (2) each 110 mm Blade diameter × 1.6mm thickness, 24 teeth. The maximum blade RPM is 2000. The blade replacement number is: RB- BNCE-NH

Operation

• Check and Preparation of Working Environment
• Check the following before using the Cutting Edge Saw. Always observe the instructions and prohibited items.
• Checking of weather conditions, do not use in the rain or snow
  ! DANGER: The Cutting Edge is not a waterproof power tool. If it becomes wet, the power source system may become faulty, or the operator may be in danger of an electric shock. Therefore, when it is raining or snowing, never operate this saw outdoors, on top of buildings or under roofs where rain or snow enters freely. Also, do not use where water accumulates or in any wet conditions

Operating Instructions

Attach the front handle in the mounting hole that provides the best grip. To operate the trigger, depress the trigger to start the saw. Start the saw before cutting, and then apply a light pressure moving forward through the cut. Do not use excessive force. DANGER: Electric Shock Hazard. Ignoring this warning may lead to death or severe injury. When raining or snowing, do not operate outdoors or indoors where rain or snow enters freely or in extreme temperatures. Do not use in extreme hot or cold conditions. The tool is designed for use under an allowable environmental temperature of 0 to 120°F. Operation at a higher temperature may cause the tool’s central unit to overheat. Likewise, operation in extreme cold or high humidity can cause the device to fail due to condensation. Do not operate the Cutting Edge Saw™ in snow or icy conditions or inside refrigerators where the temperature is freezing or below.

Check The State of Your Work Site.
Before using the tool, check whether the state of the worksite is as follows. Is the area free of foreign objects, debris, water, ice, snow, powered electrical cables, and excessive dust? Is the floor free of obstructions? Is there adequate ventilation? Is the worker adequately insulated from the ground? Then, follow the operation instructions and avoid hazardous conditions.

Remove Hazardous Substances.
Since the tool is battery-operated, it may spark and cause an explosion or a fire if oper-ated near flammable gas, thinners, explosives and other hazardous substances. Therefore, do not use the tool in areas where dangerous substances are present. Ignoring this warning may cause death or severe injury. Regular Maintenance Clean the entire unit occasionally by removing dust, debris, and oils. Periodically remove the flush cutting bottom plate; then remove any cutting chips that remain lodged in the area the cutting blade rotated. We recommend that the cutting blade be removed and inspected for any materials that did not exit the chip exhaust area. Inspection should be done after 4-8 hours of use. Most material cutting chips would normally exit the chip exhaust area and into the Cutting Chip Catch Bag. We recommend that the Cut-ting Chip Catch bag be emptied when it becomes 2/3 full of cut material.

RB-BNCE-NH Blade
The Blade for the BNCE-20-24V Cutting Edge Saw™ should be replaced when the blade is dull or chipped and a noticeable increase in cutting time has occurred.
To change the Blade, remove the screws that hold the Blade Cover to the Body. Next, remove the cover and unscrew the four bolts holding the blade to the Hub. Replacement blades have new screws to be used when installing the new blade. Make sure that you clean out any metal debris that has not escaped the tool when you remove the blade. An optional Steel Mesh Blade is available to improve the cutting capability of the BNCE-20-24V when cutting mesh materials.
