MITRE SAW
DWS727

ENGLISH
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.
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 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) 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.

10
ENGLISH
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 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.
Additional Safety Rules for Mitre Saws
WARNING: Do not connect to the mains power supply into the unit
until complete instructions are read andunderstood.
• DO NOT OPERATE THIS MACHINE until it is completely assembled and
installed according to the instructions. A machine incorrectly assembled
can cause seriousinjury.
• OBTAIN ADVICE from your supervisor, instructor, or another qualified
person if you are not thoroughly familiar with the operation of this
machine. Knowledge issafety.
• MAKE CERTAIN the blade rotates in the correct direction. The teeth on the
blade should point in the direction of rotation as marked on thesaw.
• TIGHTEN ALL CLAMP HANDLES, knobs and levers prior to operation.
Loose clamps can cause parts or the workpiece to be thrown at
highspeeds.
• BE SURE all blade and blade clamps are clean, recessed sides of blade
clamps are against blade and arbour screw is tightened securely. Loose or
improper blade clamping may result in damage to the saw and possible
personalinjury.
• DO NOT OPERATE ON ANYTHING OTHER THAN THE DESIGNATED
VOLTAGE for the saw. Overheating, damage to the tool and personal
injury mayoccur.
• DO NOT WEDGE ANYTHING AGAINST THE FAN to hold the motor
shaft. Damage to tool and possible personal injury mayoccur.
• NEVER CUT METALS or masonry. Either of these can cause the carbide
tips to fly off the blade at high speeds causing seriousinjury.
• NEVER HAVE ANY PART OF YOUR BODY IN LINE WITH THE PATH OF
THE SAW BLADE. Personal injury willoccur.
• NEVER APPLY BLADE LUBRICANT TO A RUNNING BLADE. Applying
lubricant could cause your hand to move into the blade resulting in
seriousinjury.
• DO NOT place either hand in the blade area when the saw is connected to
the power source. Inadvertent blade activation may result in seriousinjury.
• NEVER REACH AROUND OR BEHIND THE SAW BLADE. A blade can
cause seriousinjury.
• DO NOT REACH UNDERNEATH THE SAW unless it is unplugged and
turned off. Contact with saw blade may cause personalinjury.
• SECURE THE MACHINE TO A STABLE SUPPORTING SURFACE.
Vibration can possibly cause the machine to slide, walk, or tip over,
causing seriousinjury.
• USE ONLY CROSSCUT SAW BLADES recommended for mitre saws.
For best results, do not use carbide tipped blades with hook angles in
excess of 7 degrees. Do not use blades with deep gullets. These can deflect
and contact the guard, and can cause damage to the machine and/or
seriousinjury.
• USE ONLY BLADES OF THE CORRECT SIZE AND TYPE specified for this
tool to prevent damage to the machine and/or serious injury (complying
with EN847-1).
• INSPECT BLADE FOR CRACKS or other damage prior to operation. A
cracked or damaged blade can come apart and pieces can be thrown at
high speeds, causing serious injury. Replace cracked or damaged blades
immediately. Observe the maximum speed marked on the sawblade.
• THE MAXIMUM SPEED OF THE SAW BLADE shall always be greater
than or at least equal to the speed marked on the rating plate of the tool.
• THE SAW BLADE DIAMETER must be in accordance with the markings
on rating plate of the tool.
• CLEAN THE BLADE AND BLADE CLAMPS prior to operation. Cleaning
the blade and blade clamps allows you to check for any damage to the
blade or blade clamps. A cracked or damaged blade or blade clamp
can come apart and pieces can be thrown at high speeds, causing
seriousinjury.

Residual Risks
The following risks are inherent to the use of saws:
• Injuries caused by touching the rotatingparts.
In spite of the application of the relevant safety regulations and the
implementation of safety devices, certain residual risks cannot be avoided.
These are:
• Impairment ofhearing.
• Risk of accidents caused by the uncovered parts of the rotating sawblade.
• Risk of injury when changing theblade.
• Risk of squeezing fingers when opening theguards.
• Health hazards caused by breathing dust developed when sawing wood,
especially oak, beech andMDF.
The following factors increase the risk of breathing problems:
• No dust extractor connected when sawingwood.
• Insufficient dust extraction caused by uncleaned exhaustfilters.
SAVE THESE INSTRUCTIONS
• DO NOT USE WARPED BLADES. Check to see if the blade runs true and
is free from vibration. A vibrating blade can cause damage to the machine
and/or seriousinjury.
• DO NOT use lubricants or cleaners (particularly spray or aerosol) in the
vicinity of the plastic guard. The polycarbonate material used in the guard
is subject to attack by certainchemicals.
• KEEP GUARD IN PLACE and in workingorder.
• ALWAYS USE THE KERF PLATE AND REPLACE THIS PLATE WHEN
DAMAGED. Small chip accumulation under the saw may interfere with
the saw blade or may cause instability of workpiece whencutting.
• USE ONLY BLADE CLAMPS SPECIFIED FOR THIS TOOL to prevent
damage to the machine and/or seriousinjury.
• MAKE SURE to use the correct saw blade for the material to becut.
• CLEAN THE MOTOR AIR SLOTS of chips and sawdust. Clogged motor
air slots can cause the machine to overheat, damaging the machine and
possibly causing a short which could cause seriousinjury.
• NEVER LOCK THE SWITCH IN THE “ON” POSITION. Severe personal
injury mayresult.
• NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or
if the cutting tool is unintentionallycontacted.
WARNING: Cutting plastics, sap coated wood, and other materials
may cause melted material to accumulate on the blade tips and the
body of the saw blade, increasing the risk of blade overheating and
binding whilecutting.
WARNING: Always wear proper personal hearing protection.
Under some conditions and duration of use, noise from this product
may contribute to hearing loss. Be aware of the following factors
influencing exposure to noise:
• Use saw blades designed to reduce the emitted noise,
• Use only well sharpened saw blades, and
• Use specifically designed noise-reduction sawblades.
WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT
safety glasses. Also use face or dust mask if cutting operation isdusty.
WARNING: Use of this tool can generate and/or disperse dust, which
may cause serious and permanent respiratory or otherinjury.
WARNING: Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities contains chemicals known to
cause cancer, birth defects or other reproductive harm. Some examples
of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry
products, and
• arsenic and chromium from chemically-treatedlumber.
Your risk from these exposures varies, depending on how often you do this type
of work. To reduce your exposure to these chemicals: 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.
• 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.
WARNING: Use of this tool can generate and/or disperse dust, which

any adjustments or removing/installing attachments or
accessories. An accidental start-up can causeinjury.
Unpacking (Fig. A1,F)
1. Open the box and lift the saw out by the convenient carrying handle3,
as shown in FigureF.
2. Place the saw on a smooth, flatsurface.
3. Release the rail lock knob6, and push the saw head back to lock it in
the rearposition.
4. Press down lightly on the operating handle2 and pull out the lock
down pin11.
5. Gently release the downward pressure and hold the operating handle,
allowing it to rise to its fullheight.
Bench Mounting (Fig. A1)
Holes18 are provided in all four feet to facilitate bench mounting. Two
different-sized holes are provided to accommodate different sizes of screws.
Use either hole; it is not necessary to useboth.
Always mount your saw firmly to a stable surface to prevent movement.
To enhance the tool’s portability, it can be mounted to a piece of 12.7 mm
or thicker plywood which can then be clamped to your work support or
moved to other job sites andreclamped.
NOTE: If you elect to mount your saw to a piece of plywood, make sure that
the mounting screws don’t protrude from the bottom of the wood. The
plywood must sit flush on the work support. When clamping the saw to
any work surface, clamp only on the clamping bosses where the mounting
screw holes are located. Clamping at any other point will interfere with the
proper operation of thesaw.
CAUTION: To prevent binding and inaccuracy, be sure the mounting
surface is not warped or otherwise uneven. If the saw rocks on the
surface, place a thin piece of material under one saw foot until the saw
sits firmly on the mountingsurface.
Assembling the Base Extensions (Fig. Y)
WARNING: Base extensions must be assembled to both sides of
the saw's base before using thesaw.
WARNING: Be sure to adjust the base extensions using the
mounting slots so they are level with the saw'sbase.
1. Locate the holes above the hand indentations16 on the side of
thebase.
2. Using the supplied wrench or a T30 wrench, attach the screw60

Adjustment
Your mitre saw is fully and accurately adjusted at the factory at the time of
manufacture. If readjustment due to shipping and handling or any other
reason is required, follow the instructions below to adjust your saw. Once
made, these adjustments should remainaccurate.
Mitre Scale Adjustment (Fig.H, K)
1. Unlock the mitre lock handle21 and swing the mitre arm until the
mitre latch button5 locks it at the 0° mitre position. Do not lock the
mitre lockhandle.
2. Place a square against the saw’s fence and blade, as shown. (Do not
touch the tips of the blade teeth with the square. To do so will cause an
inaccurate measurement.)
3. If the saw blade is not exactly perpendicular to the fence, loosen the
four screws49 that hold the mitre scale19 and move the mitre lock
handle and the scale left or right until the blade is perpendicular to the
fence, as measured with thesquare.

Through-Cutting Operations (Fig. A1, A2,O,P)
If the slide feature is not used, ensure the saw head is pushed back as far
as possible and the rail lock knob6 is tightened. This will prevent the saw
from sliding along its rails as the workpiece isengaged.
Cutting of multiple pieces is not recommended but can be done safely by
ensuring that each piece is held firmly against the table andfence.
Straight Vertical Crosscut
1. Set and lock the mitre arm at zero, and hold the wood firmly on the
table17 and against the fence13.
2. With the rail lock knob6 tightened, turn on the saw by pushing the
lock-off lever 23 and squeezing the trigger switch22.
3. When the saw comes up to speed, lower the arm smoothly and slowly
to cut through the wood. Let the blade come to a full stop before
raisingarm.
Sliding Crosscut (Fig. O)
When cutting anything larger than a 51 x 115mm (51 x 82mm at
45° mitre) workpiece, use an out-down-back motion with the rail lock
knob6loosened.
Pull the saw out toward you, lower the saw head down toward the
workpiece, and slowly push the saw back to complete thecut.
Do not allow the saw to contact the top of the workpiece while pulling out.
The saw may run toward you, possibly causing personal injury or damage
to theworkpiece.
Mitre Crosscut (Fig. P)
The mitre angle is often 45° for making corners, but can be set anywhere
from zero to 50° left or 60° right. Proceed as for a straight verticalcrosscut.
When performing a mitre cut on workpieces wider than 51 x 105mm that
are shorter in length, always place the longer side against thefence.
Bevel Cut (Fig. A1, A2)
Bevel angles can be set from 49° right to 49° left and can be cut with the
mitre arm set between 50° left or 60° right. Refer to the Features and
Controls section for detailed instructions on the bevelsystem.
1. Loosen the bevel lock31, and move the saw to the left or right as
desired. It is necessary to move the fence13 to allow clearance.
Tighten the fence adjustment knob12 after positioning thefences.
2. Tighten the bevel lockfirmly.
At some extreme angles, the right side fence might have to be removed.
Refer to Fence Adjustment in the Adjustments section for important
information on adjusting the fences for certain bevelcuts.
To remove the right fence, unscrew the fence adjustment knob12 several
turns and slide the fenceout. The right fence is secured to the base with a
lanyard to prevent it from beinglost.
Quality of Cut
The smoothness of any cut depends on a number of variables, such as the
material being cut, blade type, blade sharpness and rate ofcut.
When smoothest cuts are desired for molding and other precision work, a
sharp (60 tooth carbide) blade and a slower, even cutting rate will produce
the desiredresults.
WARNING: Ensure that the material does not move or creep while
cutting; clamp it securely in place. Always let the blade come to a full
stop before raising arm. If small fibres of wood still split out at the rear
of the workpiece, stick a piece of masking tape on the wood where
the cut will be made. Saw through the tape and carefully remove tape
whenfinished.
Non-Through-Cutting (Grooving and Rabbeting)
(Fig. A2)
Your saw is equipped with a grooving stop28, depth adjustment
screw27 and wing nut26 to allow for groovecutting. Instructions in the
Crosscuts, Bevel Cuts and Cutting Compound Mitres sections are for cuts
made through the full thickness of the material. The saw can also perform
non-through cuts to form grooves or rabbets in thematerial.
Grooving (Fig. A1, A2)
Refer to Grooving Stop for detailed instructions for setting depth of cut. A
piece of scrap wood should be used to verify the desired depth ofcut.
1. Hold the wood firmly on the table and against the fence 13 . Align
the cut area underneath the blade. Position the saw arm fully forward,
with blade in down position. Turn on the saw by pushing the lock off-
lever23 and squeezing the trigger switch22 . Smoothly, push saw
arm rearward to cut a groove through the workpiece.
2. Release the trigger switch with the saw arm down. When saw blade has
completely stopped, raise the saw arm. Always let the blade come to a
full stop before raising thearm.
3. To widen the groove, repeat steps 1–2 until the desired width
isobtained.
Clamping the Workpiece (Fig.B)
WARNING: A workpiece that is clamped, balanced and secure
before a cut may become unbalanced after a cut is completed. An
unbalanced load may tip the saw or anything the saw is attached to,
such as a table or workbench. When making a cut that may become
unbalanced, properly support the workpiece and ensure the saw is
firmly bolted to a stable surface. Personal injury mayoccur.
WARNING: The clamp foot must remain clamped above the base of
the saw whenever the clamp is used. Always clamp the workpiece to
the base of the saw – not to any other part of the work area. Ensure
the clamp foot is not clamped on the edge of the base of thesaw.
CAUTION: Always use a work clamp to maintain control and reduce
the risk of personal injury and workpiecedamage.
Use the material clamp37 provided with your saw. The left or right fence
will slide from side to side to aid in clamping. Other aids such as spring
clamps, bar clamps or C-clamps may be appropriate for certain sizes and
shapes ofmaterial.
To Install Clamp
1. There are four rectangular clamp mounting holes 65 in the base, two
in the front and two on the back of the saw under the base fence. Insert
the clamp 37 into one of the fourholes.
NOTE: When assembling the clamp on the back side of the saw, the
arm of the clamp will need to be at the highest position so that clamp
post can be slid into the mounting hole as the clamp passes over
thefence.
2. Loosen the knob to adjust the clamp up or down, tighten the knob to
firmly clamp theworkpiece.
NOTE: Place the clamp on the opposite side of the base when beveling.
ALWAYS MAKE DRY RUNS (UNPOWERED) BEFORE FINISH CUTS TO CHECK
THE PATH OF THE BLADE. ENSURE THE CLAMP DOES NOT INTERFERE WITH
THE ACTION OF THE SAW ORGUARDS.
Support for Long Pieces (Fig.D)
ALWAYS SUPPORT LONGPIECES.
For best results, use the DE7023-XJ or DE7033 leg stands39 to extend
the table width of your saw. Support long workpieces using any
convenient means such as sawhorses or similar devices to keep the ends
fromdropping.

Cutting Picture Frames, Shadow Boxes And Other
Four-Sided Projects (Fig.Q, R)
Try a few simple projects using scrap wood until you develop a “feel” for
your saw. Your saw is the perfect tool for mitring corners like the one shown
in FigureQ.
Sketch 1 in FigureR shows a joint made with the bevel adjustment method.
The joint shown can be made using eithermethod.
• Using bevel adjustment:
-The bevel for the two boards is adjusted to 45° each, producing a
90°corner.
-The mitre arm is locked in the zero position and the bevel
adjustment is locked at 45°.
-The wood is positioned with the broad flat side against the table
and the narrow edge against thefence.
• Using mitre adjustment:
-The same cut can be made by mitring right and left with the broad
surface against thefence.
Cutting Trim Molding and Other Frames (Fig.R)
Sketch 2 in FigureR shows a joint made by setting the mitre arm at 45° to
mitre the two boards to form a 90° corner. To make this type of joint, set
the bevel adjustment to zero and the mitre arm to 45°. Once again, position
the wood with the broad flat side on the table and the narrow edge against
thefence.
The two sketches in FigureR are for four-sided objects only. As the number
of sides changes, so do the mitre and bevel angles. The chart below gives
the proper angles for a variety of shapes, assuming that all sides are of
equallength.
NUMBER OF SIDES MITRE OR BEVEL ANGLE
445°
536°
630°
725.7°
822.5°
920°
10 18°
For a shape that is not shown in the chart, use the following formula: 180°
divided by the number of sides equals the mitre (if the material is cut
vertically) or bevel angle (if the material is cut layingflat).
Cutting Compound Mitres (Fig.S)
A compound mitre is a cut made using a mitre angle and a bevel angle at
the same time. This is the type of cut used to make frames or boxes with
slanting sides like the one shown in FigureS.
WARNING: If the cutting angle varies from cut to cut, check that the
bevel lock knob and the mitre lock handle are securely locked. These
must be locked after making any changes in bevel ormitre.
The chart shown below will assist you in selecting the proper bevel and
mitre settings for common compound mitrecuts.
Set this miter angle on saw
Angle of side of box (angle ”A”)
Set this bevel angle on saw
• Select the desired angle A (Fig.S) of your project and locate that angle
on the appropriate arc in thechart.
• From that point follow the chart straight down to find the correct bevel
angle and straight across to find the correct mitreangle.
• Set your saw to the prescribed angles and make a few trial cuts. Practise
fitting the cut piecestogether.
EXAMPLE: To make a 4-sided box with 26° exterior angles (Angle A, Fig.S),
use the upper right arc. Find 26° on the arc scale. Follow the horizontal
intersecting line to either side to get mitre angle setting on saw (42°).
Likewise, follow the vertical intersecting line to the top or bottom to get the
bevel angle setting on the saw (18°). Always try cuts on a few scrap pieces
of wood to verify the settings on thesaw.
Cutting Base Moulding (Fig.J, T)
To complete straight 90° cuts, position the wood against the fence and hold
it in place as shown in FigureT. Turn on the saw, allow the blade to reach
full speed and lower the arm smoothly through thecut.
Cutting Base Moulding from 70 mm up to 150 mm High
Vertically Against the Fence (Fig. J, T)
NOTE: Use the slide lock lever59, shown in FigureJ, when cutting base
moulding measuring from 70 mm to 150 mm high vertically against
thefence.
Position material as shown in FigureT.
All cuts should be made with the back of the moulding against the fence
and with the bottom of the moulding against thetable.

Cutting Crown Moulding (Fig. A1, U1, U2)
Your mitre saw is well suited to the task of cutting crown moulding. In
order to fit properly, crown moulding must be compound mitred with
extremeaccuracy.
Your mitre saw has special pre-set mitre latch points at 22.5°, 31.6° and
35.3° left and right for cutting crown moulding at the proper angle and
bevel stop pawls at 22.5° and 30° left and right. There is also a mark on

Before use, carefully check the upper guard, lower guard and dust duct
to determine that they will operate properly. Ensure that chips, dust or
workpiece particles do not block of one of thefunctions.
In case of workpiece fragments jammed between the saw blade and
guards, disconnect the machine from the power supply and follow the
instructions given in Changing or Installing a New Saw Blade. Remove
the jammed parts and reassemble the sawblade.
Periodically clean all dust and wood chips from around AND UNDER the
base and the rotarytable.
Worklight Cleaning
• Carefully clean sawdust and debris from worklight lens with a cotton
swab. Dust build-up can block the worklight and prevent it from
accurately indicating the line ofcut.
• DO NOT use solvents of any kind; they may damage thelens.
• With blade removed from saw, clean pitch and build-up fromblade.
Dust Duct Cleaning
With the saw unplugged and the saw head raised fully, low pressure air or a
large diameter dowel rod can be used to clear the dust out of the dustduct.
Cleaning
WARNING: Blow dirt and dust out of the main housing with dry air
as often as dirt is seen collecting in and around the air vents. Wear
approved eye protection and approved dust mask when performing
thisprocedure.
WARNING: Never use solvents or other harsh chemicals for cleaning
the non-metallic parts of the tool. These chemicals may weaken the
materials used in these parts. Use a cloth dampened only with water
and mild soap. Never let any liquid get inside the tool; never immerse
any part of the tool into aliquid.
Lubrication
Your power tool requires no additionallubrication.
MAINTENANCE
Your power tool has been designed to operate over a long period of
time with a minimum of maintenance. Continuous satisfactory operation
depends upon proper tool care and regularcleaning.
WARNING:To reduce the risk of serious personal injury, turn
tool off and disconnect tool from power source before making
any adjustments or removing/installing attachments or
accessories. An accidental start-up can cause injury.

Alternative Method for Cutting Crown Moulding
Cutting crown moulding using this method does not require a bevel cut.
Minute changes in the mitre angle can be made without affecting the
bevel angle. When corners other than 90° are encountered, the saw can be
quickly and easily adjusted forthem.
Instructions for Cutting Crown Moulding Angled Between
the Fence and Base of the Saw for All Cuts (Fig. U2)
1. Angle the moulding so the bottom of the moulding (the part which
goes against the wall when installed) is against the fence13 and the
top of the moulding is resting on the saw table17.
2. The angled “flats” on the back of the moulding must rest squarely on
the fence and sawtable.

Special Cuts
WARNING: Never make any cut unless the material is secured
on the table and against thefence.
Aluminum Cutting (Fig. V1, V2)
ALWAYS USE THE APPROPRIATE SAW BLADE MADE ESPECIALLY FOR
CUTTINGALUMINUM.
Certain workpieces may require the use of a clamp or fixture to prevent
movement during the cut. Position the material so that you will be cutting
the thinnest cross section, as shown in FigureV1. FigureV2 illustrates the
wrong way to cut theseextrusions.
Use a stick wax cutting lubricant when cutting aluminum. Apply the stick
wax directly to the saw blade45 before cutting. Never apply stick wax to
a moving blade. The wax provides proper lubrication and keeps chips from
adhering to theblade.
Bowed Material (Fig. W1, W2)
When cutting bowed material always position it as shown in FigureW1 and
never like that shown in FigureW2. Positioning the material incorrectly will
cause it to pinch theblade.
Cutting Plastic Pipe or Other Round Material
Plastic pipe can be easily cut with your saw. It should be cut just like
wood and CLAMPED OR HELD FIRMLY TO THE FENCE TO KEEP IT FROM
ROLLING. This is extremely important when making anglecuts.
Cutting Large Material (Fig.X)
Occasionally you will encounter a piece of wood a little too large to fit
beneath the lower guard. If this occurs, place your right thumb on the
upper side of the guard1 and roll the guard up just enough to clear the
workpiece, as shown in FigureX. Avoid doing this as much as possible, but
if need be, the saw will operate properly and make the bigger cut. NEVER
TIE, TAPE, OR OTHERWISE HOLD THE GUARD OPEN WHEN OPERATING
THISSAW.
