General power tool safety warnings
WARNING Read all safety warnings, instructions,
illustrations 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.
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
a) Keep work area clean and well lit.Cluttered or
dark areas invite accidents.
b) 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.
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 or under
the influence of drugs, alcohol or medication. A
moment of inattention while operating power tools
may result in serious personal injury.
b) 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.
c) 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.

d) 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.
e) Do not overreach. Keep proper footing and
balance at all times. This enables better control of
the power tool in unexpected situations.
f) 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.
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
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.
e) 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.
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 situation.
h) 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
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.
f) Do not expose a battery pack or tool to fire or
excessive temperature.Exposure to fire or
temperature above 130 °C may cause explosion.
NOTE The temperature „130 °C“ can be replaced by
the temperature „265 °F“.
g) Follow all charging instructions and do not
charge the battery pack or tool outside the
temperature range specified in the instructions.
Charging improperly or at temperatures outside the
specified range may damage the battery and
increase the risk of fire.
6) Service
a) Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
b) Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
Safety instructions for mitre saws
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.
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 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.
Use only a saw blade diameter in accordance with
the markings on the saw and information about the
bore diameter and the maximum kerf of the saw
blade.

Use only saw blades that are marked with a speed
equal or higher than the speed marked on the tool.
Adjust the saw for proper cutting capacity, if
applicable.
If adjustable and/or removable workpiece support
extensions are provided always fix and use these
extensions during operation.
Avoid overheating the saw blade tips.
Use only saw blades recommended by the
manufacturer, which conform to EN 847-1.
Always check if the saw blade guard is working
properly. It shall be well assembled, and it shall be
easily moving with hand and that it can be locked
when operating the tool (see in instructions for use).

CROSS CUT
If possible, always use a clamping device such as a ‘G"
clamp to secure your workpiece.
When cutting your workpiece, keep your hands well away
from the blade area.
Do not remove a cut-off piece on the right-hand side of
the blade using your left hand.
A crosscut is made by cutting across the grain of the
workpiece. A 90°crosscut is made with the mitre table set
at 0°. Mitre crosscuts are made with the table set at some
angle other than zero.
1. Pull on the release knob (4) and lift the saw arm (3) to its
full height.
2. Loosen the mitre locks (20) and lifting up the mitre
latch(21) .
3. Rotate the mitre table (16) until the pointer aligns with
the desired angle.
4. Release mitre latch(21) and retighten the mitre locks
(20).
5. Place the workpiece flat on the table with one edge
securely against the fence (14). If the board is warped,
place the convex side against the fence (14). If the concave
side is placed against the fence, the board could break and
jam the blade.
6. When cutting long pieces of timber, support the opposite
end of the timber with side support bars, a roller stand or a
work surface that is level with the saw table.
7. Before turning on the saw, perform a dry run of the
cutting operation to check that there are no problems such
as a clamp interfering with the cutting action.
8. Hold the operating handle (5) firmly and squeeze the
release latch (30). Allow the blade to reach maximum
speed and slowly lower the blade into and through the
workpiece.
9. Release the switch trigger (19) and allow the saw blade
to stop rotating before raising the blade out of the
workpiece. Wait until the blade stops before removing the
workpiece.
BEVEL CUT
If possible, always use a clamping device such as a ‘G"
clamp to secure your workpiece.
When cutting your workpiece, keep your hands well away
from the blade area.
Do not remove a cut-off piece on the right-hand side of the
blade using your left hand.
A bevel cut is made by cutting across the grain of the
workpiece with the blade angled to the fence and mitre
table. The mitre table is set at the zero degree position and
the blade set at an angle between 0°and 45°.
1. Pull on the release knob (4) and lift the saw arm to its full
height.
2. Loosen the mitre locks (20) and lifting up the mitre latch
(21).
3. Rotate the mitre table (16) until the pointer aligns with
zero on the mitre scale (17).
4. Release mitre latch (21) and retighten the mitre locks
(20).
5. Loosen the bevel lock (12) and move the saw arm (3) to
the left to the desired bevel angle (between 0°and 45°).
Tighten the bevel lock (12).
6. Place the workpiece flat on the table with one edge
securely against the fence (14). If the board is warped,
place the convex side against the fence. If the concave
side is placed against the fence, the board could break and
jam the blade.
7. When cutting long pieces of timber, support the opposite
end of the timber with side support bars, a roller stand or a

work surface that is level with the saw table.
8. Before turning on the saw, perform a dry run of the
cutting operation to check that there are no problems
such as a clamp interfering with the cutting action.
9. Hold the operating handle (5) firmly and squeeze the
release latch (30). Allow the blade to reach maximum
speed and slowly lower the blade into and through the
workpiece.
10. Release the switch trigger (19) and allow the saw
blade to stop rotating before raising the blade out of the
workpiece. Wait until the blade stops before removing the
workpiece.
ATTACH FENCE
1. For cutting safety always use two attach fence.
2. If use bevel cut , drag out the attach fence. The attach
fence distance moving parts about 3-8mm at any times.
COMPOUND MITRE CUT
If possible, always use a clamping device such as a ‘G"
clamp to secure your workpiece.
When cutting your workpiece, keep your hands well away
from the blade area.
Do not remove a cut-off piece on the right-hand side of
the blade using your left hand.
A compound mitre cut involves using a mitre angle and a
bevel angle at the same time. It is used in making picture
frames, to cut mouldings, making boxes with sloping
sides and for roof framing. Always make a test cut on a
piece of scrap wood before cutting into the good material.
1. Pull on the release knob (4) and lift the saw arm to its
full height.
2. Loosen the mitre locks (20) and lifting up the mitre
latch (21) ..
3. Rotate the mitre table (16) until the pointer aligns with
the desired angle on the mitre scale (17).
4. Release mitre latch (21) and retighten the mitre locks
(20).
5. Loosen the bevel lock (12) and move the saw arm (3)
to the left to the desired bevel angle (between 0°and 45°).
Tighten the bevel lock (12).
6. Place the workpiece flat on the table with one edge
securely against the fence (14). If the board is warped,
place the convex side against the fence. If the concave
side is placed against the fence, the board could break
and jam the blade.
7. When cutting long pieces of timber, support the
opposite end of the timber with the side support bars, a
roller stand or a work surface that is level with the saw
table.
8. Before turning on the saw, perform a dry run of the
cutting operation to check that there are no problems
such as a clamp interfering with the cutting action.
