Instruction & User Manual
Read all safety warnings, instructions and
specifications provided with this power
tool. Failure to follow all instructions listed below
may result in electric shock, fire and/or serious
injury. Save all warnings and instructions for
future reference.
WARNING!
The term “power tool” in the warnings refers to
your mains operated (corded) power tool or battery
operated (cordless) power tool.
1. Work area safety
m Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
m Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power
tools create sparks which may ignite the dust or
fumes.
m Keep children and bystanders away while
operating a power tool. Distractions can
cause you to lose control.
2. Electrical safety
m 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.
m 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.
m Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
m Do not abuse the cord. Never use the
cord for carrying, pulling or unplugging
the power tool. Keep the cord away from
heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of
electric shock.
m 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.
m 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
m 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.
m Use personal protective equipment.
Always wear eye protection. Protective
equipment such as a dust mask, non-skid safety
shoes, hard hat or hearing protection used for
appropriate conditions will reduce personal
injuries.
m 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 finger on
the switch or energising power tools that have
the switch on invites accidents.
GENERAL POWER TOOL SAFETY WARNINGS

6JCB-20BLMS
Instruction & User Manual
m 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.
m Do not overreach. Keep proper footing
and balance at all times. This enables
better control of the power tool in unexpected
situations.
m Dress properly. Do not wear loose
clothing or jewellery. Keep your hair and
clothing away from moving parts. Loose
clothes, jewellery or long hair can be caught in
moving parts.
m 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.
m 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
m 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.
m 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.
m 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.
m Store idle power tools out of the reach

unfamiliar with the power tool or these
instructions to operate the power tool.
Power tools are dangerous in the hands of
untrained users.
m Maintain power tools and accessories.
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.
m Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier
to control.
m 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 situation.
m Keep handles and grasping surfaces
dry, clean and free from oil and grease.
Slippery handles and grasping surfaces do not
allow for safe handling and control of the tool in
unexpected situations.
5. Battery tool use and care
m 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.
m Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and fire.

8JCB-20BLMS
Instruction & User Manual
a) Mitre saws are intended to cut wood or
wood-like products, they cannot be used
with abrasive cut-off wheels for cutting
ferrous material such as bars, rods, studs,
etc. Abrasive dust causes moving parts such as
the lower guard to jam. Sparks from abrasive
cutting will burn the lower guard, the kerf insert
and other plastic parts.
b) Use clamps to support the workpiece
whenever possible. If supporting the
workpiece by hand, you must always keep
your hand at least 100 mm from either
side of the saw blade. Do not use this saw
-to cut pieces that are too small to be
securely clamped or held by hand. If your
hand is placed too close to the saw blade, there
is an increased risk of injury from blade contact.
c) The workpiece must be stationary and
clamped or held against both the fence
and the table. Do not feed the workpiece
into the blade or cut “freehand” in any
way. Unrestrained or moving· workpieces could
be thrown at high speeds, causing injury.
d) Push the saw through the workpiece. Do
not pull the saw through the workpiece.
To make a cut, raise the saw head and
pull it out over the workpiece without
cutting, start the motor, press the saw
head down and push the saw through
the workpiece. Cutting on the pull stroke is
likely to cause the saw blade to climb on top
of the workpiece and violently throw the blade
assembly towards the operator.
e) Never cross your hand over the intended
line of cutting either in front or behind
the saw blade. Supporting the workpiece
“cross handed” i.e. holding the workpiece to the
right of the saw blade with your left hand or vice
versa is very dangerous.
f) Do not reach behind the fence with either
hand closer than 100 mm from either side
of the saw blade, to remove wood scraps,
or for any other reason while the blade
is spinning. The proximity of the spinning saw
blade to your hand may not be obvious and you
may be seriously injured.
g) Inspect your workpiece before cutting. If
the workpiece is bowed or warped, clamp
it with the outside bowed face toward the
fence. Always make certain that there
is no gap between the workpiece, fence
and table along the line of the cut. Bent or
warped workpieces can twist or shift and may
cause binding on the spinning saw blade while
cutting. There should be no nails or foreign
objects in the workpiece.
h) Do not use the saw until the table is clear
of all tools, wood scraps, etc., except for
the workpiece. Small debris or loose pieces of
wood or other objects that contact the revolving
blade can be thrown with high speed.
i) Cut only one workpiece at a time. Stacked
multiple workpieces cannot be adequately
clamped or braced and may bind on the blade or
shift during cutting.
j) Ensure the mitre saw is mounted or
placed on a level, firm work surface
before use. A level and firm work surface
reduces the risk of the mitre saw becoming
unstable.
SAFETY INSTRUCTIONS FOR THE
MITRE SAWS

9
JCB-20BLMS
Instruction & User Manual
k) Plan your work. Every time you change
the bevel or mitre angle setting, make
sure the adjustable fence is set correctly
to support the workpiece and will not
interfere with the blade or the guarding
system. Without turning the tool “ON” and with
no workpiece on the table, move the saw blade
through a complete simulated cut to assure there
will be no interference or danger of cutting the
fence.
l) Provide adequate support such as
table extensions, saw horses, etc. for a
workpiece that is wider or longer than
the table top. Workpieces longer or wider
than the mitre saw table can tip if not securely
supported. If the cut-off piece or workpiece tips,
it can lift the lower guard or be thrown by the
spinning blade.
m) Do not use another person as a substitute
for a table extension or as additional
support. Unstable support for the workpiece
can cause the blade to bind or the workpiece to
shift during the cutting operation pulling you and
the helper into the spinning blade.
n) The cut-off piece must not be jammed
or pressed by any means against the
spinning saw blade. If confined, i.e. using
length stops, the cut-off piece could get wedged
against the blade and thrown violently.
o) Always use a clamp or a fixture designed
to properly support round material such
as rods or tubing. Rods have a tendency to
roll while being cut, causing the blade to “bite”
and pull the work with your hand into the blade.
p) Let the blade reach full speed before
contacting the workpiece. This will reduce
the risk of the workpiece being thrown.
q) If the workpiece or blade becomes
jammed, turn the mitre saw off. Wait for
all moving parts to stop and disconnect
the plug from the power source and/or
remove the battery pack. Then work to
free the jammed material. Continued sawing
with a jammed workpiece could cause loss of
control or damage to the mitre saw.
r) After finishing the cut, release the switch,
hold the saw head down and wait for the
blade to stop before removing the cut-
off piece. Reaching with your hand near the
coasting blade is dangerous.
s) Hold the handle firmly When making an
incomplete cut or when releasing the
switch before the saw head is completely
in the down position. The braking action of
the saw may cause the saw head to be suddenly
pulled downward, causing a risk of injury.
Blade Guard
m When lowering the handle, the blade guard
rises automatically. The guard is spring
loaded so it returns to it’s original position
when the cut is completed and the handle
is raised.
m NEVER DEFEAT OR REMOVE THE BLADE
GUARD OR THE SPRING WHICH
ATTACHES TO THE GUARD.
m In the interest of your personal safety, always
maintain the blade guard in good condition.
Any irregular operation of the blade guard
should be corrected immediately. Check to
assure spring loaded return action of guard.
m NEVER USE THE TOOL IF THE BLADE
GUARD OR SPRING ARE DAMAGED,
FAULTY OR REMOVED. DOING SO
IS HIGHLY DANGEROUS AND CAN
CAUSE SERIOUS PERSONAL INJURY.

Instruction & User Manual
Safety instructions for the
handling of saw blades
m Only use saw blade if you have mastered
their use.
m Observe the maximum speed. The
maximum speed specified on the saw blade
may not be exceeded. If specified, observe
the speed range.
m Observe the motor / saw blade direction of
rotation.
m Do not use any saw blades with cracks.
Dispose of cracked saw blades. Repairs are
not permitted.
m Clean grease, oil and water off of the
clamping surfaces.
m Do not use any loose reducing rings or
bushes for the reducing of holes on saw
blades.
m Make sure that fixed reducer rings for
securing the saw blade have the same
diameter and have at least 1/3 of the cutting
width.
m Make sure that fixed reducer rings are
parallel to each other.
m Handle the saw blade with caution. They
are ideally stored in the originally package or
special containers. Wear protective gloves in
order to improve grip and to further reduce
the risk of injury.
m Prior to the use of saw blades, make sure
that all protective devices are properly
fastened.
m Prior to use, make sure that the saw blade
meets the technical requirements of this
electric tool and is properly fastened.
m Only use the supplied saw blade for cutting
wood and plastic, never for the processing
of metals.
Tips for Mitre Saw Blade
Maintenance
m Avoid excessive moisture or humidity.
Otherwise, the blades may rust and/or pit.
m Keep the saw blades clean to maintain good
performance. Accumulated pitch, sap, and
other materials may dull the blade, require
more push-through force, and generate
increased levels of heat through friction.
m When cleaning the blades, never use a
wire brush. Otherwise you are likely to do
serious damage. Use a nylon or brass brush.
m It’s important to avoid overheating the
blade by keeping it too low when cutting
hardwood. This can create a thermal crack
in the carbide, causing tip fragments to fly
backward to possibly injure the operator.
m Never rest circular saw blades on steel or
cement surfaces. Metal on metal or metal
on cement can dull the blade by chipping
the top grind. Instead, it’s better to set the
blade down on plywood or plastic.
m Always use the proper type of shipping
container. Be sure that the blades do not
rub against one another, or you are likely
to get chipping. It is recommended that
heavy cardboard be used or two pieces of
plywood with a bolt through them to create
a small container.
