Safety Instruction - General Safety Rules
Warning! Read and understand all instruc-
tions. Failure to follow all instructions listed
belowmayresultinelectricshock,reand/
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ammable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
• Power tool plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs with
earthed (grounded) power tools. Unmodied plugs
and matching outlets will reduce risk of electric shock.
• Avoid body contact with earthed or grounded surfac-
es such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body
is earthed or grounded.
• Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
• Do not abuse the cord. Never use the cord for carrying,
pulling or unplugging the power tool. Keep cord away
from heat, oil, sharp edges or moving parts. Damaged
or entangled cords increase the risk of electric shock.
Replace damaged cords.
• When operating a power tool outdoors, use an exten-
sion cord suitable for outdoor use. Use of a cord suit-
able for outdoor use reduces the risk of electric shock.
• If operating a power tool in a damp location is un-
avoidable, use a residual current device (RCD) pro-
tected supply. Use of an RCD reduces the risk of elec-
tric shock.
NOTE The term ″residual current device (RCD)″ may be
replaced by the term ″ground fault circuit interrupter
(GFCI)″ or ″earth leakage circuit breaker (ELCB)″.
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 com-
mon sense when operating a power tool. Do not use a
powertoolwhileyouaretiredorundertheinuence
of drugs, alcohol or medication. A moment of inatten-
tion while operating 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 pro-
tection used for appropriate conditions will reduce
personal injuries.
• Prevent unintentional starting. Ensure the switch is
in the off-position before connecting to power source
and/orbatterypack,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
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 mov-
ing parts. Loose clothes, jewelry or long hair can be
caught in moving parts.
• If devices are provided for the connection of dust ex-
traction and collection facilities, ensure these are con-
nected and properly used. Use of dust collection can
reduce dust-related hazards.
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 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

~ Page | 4 ~
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 un-
trained 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 opera-
tion. 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 main-
tained 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 ac-
cordance 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qualiedrepair
person using only identical replacement parts. This will
ensure that the safety of the power tool is maintained.

ate the trigger, depress the trigger lock button (on the
side of the tool) and then pull the trigger to start the saw.
Start the saw before cutting and then apply a light pres-
sure moving forward through the cut.
! DANGER: Electric Shock Hazard. Ig-
noring 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 ex-
tremely cold temperature conditions. The tool is designed
for use under an allowable environmental temperature of
0 to 100°F.Operation at higher temperature may cause the
tool’s main unit to overheat. Operation at high tempera-
ture 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 work
site is as follows. Is the worksite free of foreign objects,
debris, water, ice, snow, powered electrical cables, and
excessivedust?Istheoorfreeofobstructions?Istheir
adequateventilation?Istheworkerproperlyinsulated
from the ground. Follow the operation instructions and
avoid prohibited items.
Remove Hazardous Substances.
Since the tool is an electric tool, it may spark and cause an

Maintenance of the Main Unit
Always unplug the saw from the electric outlet before attempt-
ing any maintenance. Clean the entire unit occasionally by
removingdust,debrisandoils.Occasionallyremovetheush
cutting 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 removed and
inspect 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
