General Safety Rules
Warning!
Read and understand all instructions. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious personal injury.

PLEASE SAVE THESE INSTRUCTIONS!

Work Area Safety

  • Keep the 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 flammable liquids, gases, or dust. Power tools create sparks that may ignite dust or fumes.
  • Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

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

Personal Safety

  • Always wear eye protection. Care must be taken 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 equipment 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 the switch is in the off-position before connecting to a power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
  • Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
  • Do not overreach. Keep proper footing and balance at all times. This enables better control of 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. Loose clothes, jewelry, or long hair can be caught in moving parts.
  • If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. The use of dust collection can reduce dust-related hazards.
  •  Keep fingers and body parts away from the blade opening.

Power Tool Use and Care

  • Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate at which it was designed.
  • Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
  • Disconnect the plug from the power source and/or 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 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. Many accidents are caused by poorly maintained power tools.
  • Keep cutting tools 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 in accordance with these instructions, taking 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.

Service

Have your power tool serviced only by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

Operation

  • Checking 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 get 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. Do not use where water accumulates or where water splashes.

Operation Instructions

Locate 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.

! DANGER: Electric Shock Hazard.
Ignoring this warning may lead to death or serious injury. When raining or snowing, do not operate outdoors or indoors where rain or snow enters freely or in extreme temperatures. Do not use under high temperature and humidity or extremely cold temperature 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 main unit to overheat. Operation at high temperature with high humidity may cause the tool to fail due to condensation.

Also, do not operate the Cutting Edge Saw™ in very cold places 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 work site 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 properly insulated from the ground? Follow the operation instructions and avoid prohibited items.

Remove Hazardous Substances.

Maintenance of the Main Unit

Clean the entire unit occasionally by removing dust, debris, and oils. Occasionally remove the flush cutting bottom plate; then remove any cutting chips that remain lodged in the area the cutting blade rotated.

It is also recommended that the cutting blade be removed and inspected for any materials that did not exit out the chip exhaust area. This should be done after 4-8 hours of use.  Most material cutting chips would normally exit out the chip exhaust area and into the Cutting Chip Catch Bag. It is recommended that the Cutting Chip Catch bag be emptied when it becomes 2/3 full of cut material.

RB-BNCE-KNH 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. Remove the cover and unscrew the four bolts holding the blade to the Hub. The replacement blades that you purchase have new screws to be used when installing the new blade. Make sure that when you remove the blade you clean out any metal debris that has not escaped the tool.
An optional Steel Mesh Blade is available to improve the cutting capability of the BNCE-20-24V when cutting mesh materials.
