c) Keep children and bystanders away while
operating a power tool.
Distractions can cause you to lose control.
2) Electrical safety
a) 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.
Unmodified plugs and matching outlets will reduce
risk of electric shock.
b) Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges
and refrigerators.
There is an increased risk of electric shock if your
body is earthed or grounded.
c) Do not expose power tools to rain or wet
conditions.
Water entering a power tool will increase the risk
of electric shock.
d) 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.
e) When operating a power tool outdoors, use
an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces the
risk of electric shock.
f) If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply.
Use of an RCD reduces the risk of electric shock.
3) Personal safety
a) 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

g) 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
hazards.
h) Do not let familiarity gained from frequent use
of tools allow you to become complacent and
ignore tool safety principles.
A careless action can cause severe injury within a
fraction of a second.
4) Power tool use and care
a) 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.
b) 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.
c) Disconnect the plug from the power source
and/or remove the battery pack, if detachable,
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.
d) Store idle power tools out of the reach of

breakage of parts and any other condition
that may affect the power toolʼs operation.
If damaged, have the power tool repaired
before use.
Many accidents are caused by poorly maintained
power tools.
f) Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier
to control.
g) Use the power tool, accessories and tool bits
etc. 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

unexpected situations.
5) Battery tool use and care
a) Recharge only with the charger specified by
the manufacturer.
A charger that is suitable for one type of battery
pack may create a risk of fire when used with
another battery pack.
b) Use power tools only with specifically
designated battery packs.
Use of any other battery packs may create a risk of
injury and fire.
c) When battery pack is not in use, keep it away
from other metal objects, like paper clips,
coins, keys, nails, screws or other small metal
objects, that can make a connection from one
terminal to another.
Shorting the battery terminals together may cause
burns or a fire.
d) Under abusive conditions, liquid may be
ejected from the battery; avoid contact. If
contact accidentally occurs, flush with water.
If liquid contacts eyes, additionally seek
medical help.
Liquid ejected from the battery may cause irritation
or burns.
e) Do not use a battery pack or tool that is
damaged or modified.
Damaged or modified batteries may exhibit
unpredictable behaviour resulting in fire, explosion
or risk of injury.

CORDLESS REAR HANDLE CIRCULAR
SAW SAFETY WARNINGS
Cutting procedures
a) DANGER: Keep hands away from cutting area
and the blade. Keep your second hand on sub
handle.
If both hands are holding the saw, they cannot be cut
by the blade.
b) Do not reach underneath the workpiece.
The guard cannot protect you from the blade below
the workpiece.
c) Adjust the cutting depth to the thickness of the
workpiece.
Less than a full tooth of the blade teeth should be
visible below the workpiece.
d) Never hold the workpiece in your hands or across
your leg while cutting. Secure the workpiece to a
stable platform.
It is important to support the work properly to minimise
body exposure, blade binding, or loss of control.
e) Hold the power tool by insulated gripping
surfaces, when performing an operation where
the cutting tool may contact hidden wiring.
Contact with a “live” wire will also make exposed
metal parts of the power tool “live” and could give the
operator an electric shock.
f) When ripping, always use a rip fence or straight
edge guide.
This improves the accuracy of cut and reduces the
chance of blade binding.
g) Always use blades with correct size and shape
(diamond versus round) of arbour holes.
Blades that do not match the mounting hardware of
the saw will run off-centre, causing loss of control.
h) Never use damaged or incorrect blade washers
or bolt.
The blade washers and bolt were specially designed
for your saw, for optimum performance and safety of
operation.
Kickback causes and related warnings
– kickback is a sudden reaction to a pinched, jammed
or misaligned saw blade, causing an uncontrolled saw
to lift up and out of the workpiece toward the operator;
– when the blade is pinched or jammed tightly by the
kerf closing down, the blade stalls and the motor
reaction drives the unit rapidly back toward the
operator;
– if the blade becomes twisted or misaligned in the cut,
the teeth at the back edge of the blade can dig into the
top surface of the wood causing the blade to climb out
of the kerf and jump back toward the operator.
Kickback is the result of saw misuse and/or incorrect
operating procedures or conditions and can be avoided by
taking proper precautions as given below.
a) Maintain a firm grip with both hands on the saw
and position your arms to resist kickback forces.
Position your body to either side of the blade,
but not in line with the blade.
Kickback could cause the saw to jump backwards,
but kickback forces can be controlled by the operator,
if proper precautions are taken.
b) When blade is binding, or when interrupting a
cut for any reason, release the trigger and hold
the saw motionless in the material until the blade
comes to a complete stop.
Never attempt to remove the saw from the work
or pull the saw backward while the blade is in
motion or kickback may occur.
Investigate and take corrective actions to eliminate
the cause of blade binding.
c) When restarting a saw in the workpiece, centre
the saw blade in the kerf so that saw teeth are not
engaged into the material.
If a saw blade binds, it may walk up or kickback from
the workpiece as the saw is restarted.
d) Support large panels to minimise the risk of
blade pinching and kickback.
Large panels tend to sag under their own weight.
Supports must be placed under the panel on both
sides, near the line of cut and near the edge of the
panel.
e) Do not use dull or damaged blades.
Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade binding
and kickback.
f) Blade depth and bevel adjusting locking levers
must be tight and secure before making the cut.
If blade adjustment shifts while cutting, it may cause
binding and kickback.
g) Use extra caution when sawing into existing
walls or other blind areas.
The protruding blade may cut objects that can cause
kickback.

4. Keep alert. Never operate the saw when you feel tired
or when you are under the the influence of any drugs,
alcohol or medication that could affect your ability to
use the tool properly.
5. Keep the working environment well ventilated. Some
dust created by power sanding, sawing, grinding,
drilling and other construction activities contains
chemicals to cause cancer, birth defects or other
reproductive harm. Therefore, work in a well ventilated
area, and work with approved safety equipment, such
as those dust masks that are specially designed to
filter out microscopic particles.
6. Avoid prolonged contact with dust from power
sanding, sawing, grinding, drilling, and other
construction activities. Wear protective clothing and
wash exposed areas with soap and water. Allowing
dust to get into your mouth, eyes, or lay on the skin
may promote absorption of harmful chemicals.
7. To prevent from fire or toxic reactio, never use
gasoline, naphtha acetone, lacquer thinner or similar
highly volatile solvents to clean the saw.
SPECIFIC SAFETY RULES
1. Adjustments. Before cutting be sure depth and
bevel adjustments are tight.
2. Avoid cutting nails. Inspect for and remove all
nails from work piece before cutting.
3. When operating the saw, keep the cord away
from the cutting area and position it so that it
will not be caught on the workpiece during the
cutting operation.
Operate with proper hand support, proper workpiece
support, and supply cord routing away from the work
area.
WARNING
It is important to support the work piece properly
and to hold the saw firmly to prevent loss of
control which could cause personal injury. Fig. 1
illustrates typical hand support of the saw.
A TYPICAL ILLUSTRATION OF PROPER
HAND SUPPORT WORKPIECE SUPPORT.
Fig. 1
Lower guard function
a) Check the lower guard for proper closing before
each use. Do not operate the saw if the lower
guard does not move freely and close instantly.
Never clamp or tie the lower guard into the open
position.
If the saw is accidentally dropped, the lower guard
may be bent.
Raise the lower guard with the retracting handle and
make sure it moves freely and does not touch the
blade or any other part, in all angles and depths of cut.
b) Check the operation of the lower guard spring.
If the guard and the spring are not operating
properly, they must be serviced before use.
Lower guard may operate sluggishly due to damaged
parts, gummy deposits, or a build-up of debris.
c) The lower guard may be retracted manually
only for special cuts such as “plunge cuts” and
“compound cuts”.
Raise the lower guard by the retracting handle
and as soon as the blade enters the material, the
lower guard must be released.
For all other sawing, the lower guard should operate
automatically.
d) Always observe that the lower guard is covering
the blade before placing the saw down on bench
or floor.
An unprotected, coasting blade will cause the saw to
walk backwards, cutting whatever is in its path.
Be aware of the time it takes for the blade to stop after
switch is released.
Others
1. ALWAYS wear proper apparel. Do not wear loose
clothing, gloves, neckties, rings, bracelets or other
jewelry which may get caught in moving parts to
lead personal injury. Wear protective hair covering to
contain long hair.
2. ALWAYS wear eye protection. Any power tool can
throw foreign objects into eyes and could cause
permanent eye damage.
3. Wear suitable personal protective equipment when
necessary, this could include:
● hearing protection to reduce the risk of induced
hearing loss;
● eye protection;
● respiratory protection to reduce the risk of
inhalation of harmful dust;
● gloves for handling saw blades (saw blades shall
be carried in a holder wherever practicable) and
rough material.

How to make the batteries perform longer
(1) Recharge the batteries before they become
completely exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery.
If you continue to use the tool and exhaust the electric
current, the battery may be damaged and its life will
become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
use, its internal chemical substance will deteriorate,
and the battery life will be shortened. Leave the
battery and recharge it after it has cooled for a while.
CAUTION
●
When the battery charger has been continuosly
used, the battery charger will be heated, thus
constituting the cause of the failures. Once the
charging has been completed, give 15 minutes
rest until the next charging.
● If the battery is charged while it is heated
because it has been left for a long time in a
location subject to direct sunlight or because the
battery has just been used, the charge indicator
lamp of the charger lights for 0.3 seconds, does
not light for 0.3 seconds (offfor 0.3 seconds). In
such a case, first let the battery cool, then start
charging.
● When the charge indicator lamp flickers (at
0.2–second intervals), check for and take out
any foreign objects in the charger’s battery
installation hole. If there are no foreign objects,
it is probable that the battery or charger is
malfunctioning. Take it to your authorized
Service Center.
