General Safety Rules
Warning! Read and understand all
instructions. Failure to follow all
instructions listed below may result
inelectricshock,reand/orserious
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 atmo-
spheres,suchasinthepresenceofammable
liquids, gases or dust. Power tools create
sparks which may ignite the 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 condi-
tions. Water entering a power tool will increase
the risk of damage.
Personal Safety
• Always wear eye protection. Care must be tak-
en 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
undertheinuenceofdrugs,alcoholormedi-
cation. A moment of inattention while operat-
ing power tools may result in serious personal
injury.
• Use personal protective equipment. Always
wear eye protection.Protective equipment
such as dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
• Prevent unintentional starting. Ensure the
switchisintheo-positionbeforeconnecting
topowersourceand/orbatterypack,picking
up or carrying the tool. Carrying power tools
with your nger on the switch or energizing
power tools that have the switch on invites ac-
cidents.
• 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 con-
trol 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, jew-
elry 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. Use of
dust collection can reduce dust-related haz-
ards.
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 for which it was designed.
• Do not use the power tool if the switch does not
turnitonando.Anypowertoolthatcannot
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 ac-
cessories, or storing power tools. Such preven-
tive safety measures reduce the risk of starting
the power tool accidentally.
• Store idle power tools out of the reach of chil-
dren and do not allow persons unfamiliar with
the power tool or these instructions to operate
the power tool.
~ Page | 4 ~
• Power tools are dangerous in the hands
of untrained users.
• Maintain power tools. Check for misalign-
ment or binding of moving parts, breakage of
partsandanyotherconditionthatmayaect
the power tool’s operation. If damaged, have
the power tool repaired before use. Many ac-
cidents 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 tool bits
etc. in accordance with these instructions, tak-
ing into account the working conditions and
the work to be performed. Use of the power
tool for operations dierent from those in-
tended could result in a hazardous situation.
Service
• Have your power tool serviced only by a
qualied repair person using only identi-
cal replacement parts. This will ensure that
the safety of the power tool is maintained.

Operation
Checking and Preparation of Working Environ-
ment:
Check the following before using the Cutting Edge
Saw. Always observe the instructions and prohib-
ited 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 sys-
tem may become faulty or the op-
erator 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 en-
ters 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 trig-
ger, 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 Haz-
ard. 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 higher tem-
perature 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 tempera-
ture is freezing or below.
Check The State of Your Work Site.
Before using the tool, check whether the state of the
work site is as follows. Is the worksite free of foreign
objects, debris, water, ice, snow, powered electri-
calcables,andexcessivedust?Istheoorfreeof
obstructions? Is their adequate ventilation? Is the
worker properly insulated from the ground. Fol-
low the operation instructions and avoid prohibited
items.
Remove Hazardous Substances.
Since the tool is an battery operated, it may spark

oussubstancesofhighammability.
Maintenance of the Main Unit
Clean the entire unit occasionally by removing dust,
debrisandoils.Occasionallyremovetheushcutting
bottom plate; then remove any cutting chips that re-
main lodged in the area the cutting blade rotated.
It is also recommended that the cutting blade be re-
moved and inspect for any materials that did not exit
out the chip exhaust area. This should be done af-
~ Page | 6 ~
ter 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 recommend-
ed that the Cutting Chip Catch bag be emptied
whenitbecomes2/3fullofcutmaterial.
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 pur-
chase 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 im-
prove the cutting capability of the BNCE-20-24V
when cutting mesh materials. Please see your
distributor or call BN Products-USA, LLC (www.
