GENERAL SAFETY INSTRUCTIONS
WARNING! Read all safety warnings instructions, illustrations are provided with this power tool. Failure
to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
1) Work area safety
a) Keep work area clean and well lit. Cluttered and 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 safety equipment. Always wear eye protection. Safety equipment such as 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
energizing 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 jewelry. Keep your hair, clothing and gloves away from
moving parts. Loose clothes, jewelry 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 these devices can reduce dust related hazards.

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 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. Check for misalignment or binding of moving parts, breakage of parts and any other
condition that may affect the power tools 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 and in the manner
intended for the particular type of power tool, taking into account the working conditions and the work to be
performed. Use of the power tool for operations different from intended could result in a hazardous situation.
5) 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.
SAFETY REGULATIONS CONCERNING MITRE SAW
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.

6
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. 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.
g) 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 have contact with the revolving blade can be thrown with high speed.
h) 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.
i) 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. 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 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.
j) 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.
k) 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.
l) 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.
m) 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.
n) Let the blade reach full speed before contact with the workpiece. This will reduce the risk of the workpiece
being thrown.
o) 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.
p) 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.

ADJUSTING THE MITRE ANGLE
A mitre cut is one that is at an angle across the horizontal surface of the material. A 45° miter cuts to join two pieces in a
right-angle corner are common. A 30° cut is often used for a scarf joint or to make a chamfered end.
1. Loosen the Mitre Lock Knob by turning it approximately 1/4 turn counterclockwise.
2. Pull up on the Mitre Detent Lever to unlock the Table. While holding the Mitre Detent Lever up, move the Table to the
desired angle.
3. The Mitre Angle Indicator will indicate the selected angle. While the Mitre Detent Lever is released, the Table will
lock into place at often used mitre angles, including 15°, 22.5°,30°, and 45° on both left and right sides.
4. To override the pre-set detents (stops) for micro adjustments at any angle, pull up on the Mitre Detent Lever and push
the Detent Latch Button forward and latch in place. Release the Mitre Detent Lever and adjust the Table to any
position on the miter scale. To disengage pull up on the Mitre Detent Lever to release the Detent Latch Button.
5. Tighten the Mitre Lock Knob after adjusting the miter angle.
6. With the Table adjusted to the desired angle, place the workpiece flush against the Fence, secure it with the Clamp and
make the cut.
ADJUSTING THE BEVEL ANGLE
A bevel cut is one that is at an angle vertically. Bevel cuts can be used to mitre relatively wide and thin material. Bevel
cuts can be used in combination with a mitre cut to form a compound angle. Compound angle cuts are often used in
crown moldings, picture frames and similar trim materials.
1. Loosen the Bevel Lock Knob at the rear of the saw.
2. For micro adjustments at any bevel angle, push the Bevel Detent Lever back until it snaps into place and move the
Saw Head Assembly to the desired angle. Read the angle on the Bevel Angle Indicator.

10
3. To use the pre-set detents (stops), push the Bevel Detent Lever back until the Saw Head Assembly can be moved and
then release the Lever. The Saw Head Assembly will lock into place at often used bevel angles, including 22.5°,33.9°,
and 45° on both left and right sides.
4. Lock the Saw Head Assembly into position by rotating the Bevel Lock Knob clockwise. Tighten firmly but do not
over-tighten.
5. Make a sample cut in a piece of scrap to confirm that the bevel angle is correct. If not, adjust the angle before cutting.
USING THE DEPTH STOP
If the kerfing does not cut through the workpiece is desired, use the Depth Stop to control the depth of the cut.
1. Pull out the Head Lock-Down Pin and raise the Saw Head Assembly.
2. Rotate the Depth Stop down to a horizontal position to use the Depth Adjustment Bolt setting.
3. Pull down on the Saw Head to check the current setting.
4. To change the setting, first loosen the Wing Nut on the Depth Adjustment Bolt. Turn the Depth Adjustment Bolt
clockwise to increase depth and counterclockwise to decrease depth. Tighten the Wing Nut after adjustment.
5. To disengage, rotate the Depth Stop up to its vertical position.
