EN62841 and may be used to compare one tool with another. It
may be used for a preliminary assessment ofexposure.
WARNING: The declared noise emission level represents
the main applications of the tool. However, if the tool is
used for different applications, with different accessories
or poorly maintained, the noise emission may differ. This
may significantly increase the exposure level over the total
workingperiod.
An estimation of the level of exposure to vibration should
also take into account the times when the tool is switched
off or when it is running but not actually doing the job.
This may significantly reduce the exposure level over the
total workingperiod.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool
and the accessories, keep the hands warm, organisation
of workpatterns.

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 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

10
ENGLISH
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.
Safety Instructions for Table Saws
1) Guarding Related Warnings
a ) Keep guards in place. Guards must be in working
order and be properly mounted. A guard that is loose,
damaged, or is not functioning correctly must be repaired
orreplaced.
b ) Always use saw blade guard, riving knife and anti-
kickback device for every through-cutting operation.
For through-cutting operations where the saw blade
cuts completely through the thickness of the workpiece,
the guard and other safety devices help reduce the risk
ofinjury.
c ) Immediately reattach the guarding system after
completing an operation (such as rabbeting cuts,
dadoing or resawing) which requires removal of
the guard, riving knife and/or anti-kickback device.
The guard, riving knife, and anti-kickback device help to
reduce the risk ofinjury.
d ) Make sure the saw blade is not contacting the guard,
riving knife or the workpiece before the switch is
turned on. Inadvertent contact of these items with the
saw blade could cause a hazardouscondition.
e ) Adjust the riving knife as described in this instruction
manual. Incorrect spacing, positioning and alignment
can make the riving knife ineffective in reducing the
likelihood ofkickback.
f ) For the riving knife and anti-kickback device to
work, they must be engaged in the workpiece. The
riving knife and anti-kickback device are ineffective when
cutting workpieces that are too short to be engaged with
the riving knife and anti-kickback device. Under these
conditions a kickback cannot be prevented by the riving
knife and anti-kickbackpawls.
g ) Use the appropriate saw blade for the riving knife.
For the riving knife to function properly, the saw blade
diameter must match the appropriate riving knife and the
body of the saw blade must be thinner than the thickness
of the riving knife and the cutting width of the saw blade
must be wider than the thickness of the rivingknife.
2) Cutting
a ) DANGER: Never place your fingers or hands
in the vicinity or in line with the saw blade. A
moment of inattention or a slip could direct your
hand towards the saw blade and result in serious
personalinjury.
b ) Feed the workpiece into the saw blade or cutter
only against the direction of rotation. Feeding the
workpiece in the same direction that the saw blade is
rotating above the table may result in the workpiece, and
your hand, being pulled into the sawblade.
c ) Never use the mitre gauge to feed the workpiece
when ripping and do not use the rip fence as a
length stop when cross cutting with the mitre gauge.
Guiding the workpiece with the rip fence and the mitre
gauge at the same time increases the likelihood of saw
blade binding andkickback.
d ) When ripping, always apply the workpiece feeding
force between the fence and the saw blade. Use a
push stick when the distance between the fence and
the saw blade is less than 150 mm, and use a push
block when this distance is less than 50 mm. "Work
helping" devices will keep your hand at a safe distance
from the sawblade.
e ) Use only the push stick provided by the
manufacturer or constructed in accordance with the
instructions. This push stick provides sufficient distance
of the hand from the sawblade.
f ) Never use a damaged or cut push stick. A damaged
push stick may break causing your hand to slip into the
sawblade.
g ) Do not perform any operation "freehand". Always
use either the rip fence or the mitre gauge to
position and guide the workpiece. "Freehand" means
using your hands to support or guide the workpiece, in lieu
of a rip fence or mitre gauge. Freehand sawing leads to
misalignment, binding andkickback.
h ) Never reach around or over a rotating saw blade.
Reaching for a workpiece may lead to accidental contact
with the moving sawblade.
i ) Provide auxiliary workpiece support to the rear
and/or sides of the saw table for long and/or wide
workpieces to keep them level. A long and/or wide
workpiece has a tendency to pivot on the table’s edge,
causing loss of control, saw blade binding andkickback.
j ) Feed workpiece at an even pace. Do not bend or
twist the workpiece. If jamming occurs, turn the
tool off immediately, unplug the tool then clear the
jam. Jamming the saw blade by the workpiece can cause
kickback or stall themotor.
k ) Do not remove pieces of cut-off material while the
saw is running. The material may become trapped
between the fence or inside the saw blade guard and the
saw blade pulling your fingers into the saw blade. Turn

11
ENGLISH
the saw off and wait until the saw blade stops before
removingmaterial.
l ) Use an auxiliary fence in contact with the table top
when ripping workpieces less than 2 mm thick. A
thin workpiece may wedge under the rip fence and create
akickback.
3) Kickback Causes and Related Warnings
Kickback is a sudden reaction of the workpiece due to a pinched,
jammed saw blade or misaligned line of cut in the workpiece with
respect to the saw blade or when a part of the workpiece binds
between the saw blade and the rip fence or other fixedobject.
Most frequently during kickback, the workpiece is lifted from the
table by the rear portion of the saw blade and is propelled towards
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 ) Never stand directly in line with the saw blade.
Always position your body on the same side of
the saw blade as the fence. Kickback may propel the
workpiece at high velocity towards anyone standing in
front and in line with the sawblade.
b ) Never reach over or in back of the saw blade to pull
or to support the workpiece. Accidental contact with
the saw blade may occur or kickback may drag your
fingers into the sawblade.
c ) Never hold and press the workpiece that is being
cut off against the rotating saw blade. Pressing the
workpiece being cut off against the saw blade will create a
binding condition andkickback.
d ) Align the fence to be parallel with the saw blade. A
misaligned fence will pinch the workpiece against the saw
blade and createkickback.
e ) Use a featherboard to guide the workpiece against
the table and fence when making non-through cuts
such as rabbeting cuts. A featherboard helps to control
the workpiece in the event of akickback.
f ) Support large panels to minimise the risk of saw
blade pinching and kickback. Large panels tend to sag
under their own weight. Support(s) must be placed under
all portions of the panel overhanging the tabletop.
g ) Use extra caution when cutting a workpiece that is
twisted, knotted, warped or does not have a straight
edge to guide it with a mitre gauge or along the
fence. A warped, knotted, or twisted workpiece is unstable
and causes misalignment of the kerf with the saw blade,
binding andkickback.
h ) Never cut more than one workpiece, stacked
vertically or horizontally. The saw blade could pick up
one or more pieces and causekickback.
i ) When restarting the saw with the saw blade in the
workpiece, centre the saw blade in the kerf so that
the saw teeth are not engaged in the material. If the
saw blade binds, it may lift up the workpiece and cause
kickback when the saw isrestarted.
j ) Keep saw blades clean, sharp, and with sufficient
set. Never use warped saw blades or saw blades with
cracked or broken teeth. Sharp and properly set saw
blades minimise binding, stalling andkickback.
4) Table Saw Operating Procedure Warnings
a ) Turn off the table saw and disconnect the power
cord when removing the table insert, changing
the saw blade or making adjustments to the riving
knife, anti-kickback device or saw blade guard, and
when the machine is left unattended. Precautionary
measures will avoidaccidents.
b ) Never leave the table saw running unattended.
Turn it off and don’t leave the tool until it comes
to a complete stop. An unattended running saw is an
uncontrolledhazard.
c ) Locate the table saw in a well-lit and level area
where you can maintain good footing and balance.
It should be installed in an area that provides
enough room to easily handle the size of your
workpiece. Cramped, dark areas, and uneven slippery
floors inviteaccidents.
d ) Frequently clean and remove sawdust from under
the saw table and/or the dust collection device.
Accumulated sawdust is combustible and may self-ignite.
e ) The table saw must be secured. A table saw that is not
properly secured may move or tipover.
f ) Remove tools, wood scraps, etc. from the table
before the table saw is turned on. Distraction or a
potential jam can bedangerous.
g ) Always use saw blades with correct size and shape
(diamond versus round) of arbour holes. Saw 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 saw blade mounting
means such as flanges, saw blade washers, bolts or
nuts. These mounting means were specially designed for
your saw, for safe operation and optimumperformance.
i ) Never stand on the table saw, do not use it as a
stepping stool. Serious injury could occur if the tool is
tipped or if the cutting tool is accidentallycontacted.
j ) Make sure that the saw blade is installed to rotate
in the proper direction. Do not use grinding wheels,
wire brushes, or abrasive wheels on a table saw.
Improper saw blade installation or use of accessories not
recommended may cause seriousinjury.
Additional Safety Rules for Table Saws
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.
• Avoid awkward positions, where a sudden slip could
cause a hand to move into a sawblade.
• Do not attempt to retrieve materials near the blade on
the saw table while the blade isspinning.

12
ENGLISH
• Never reach in back of, or around, the cutting tool with
either hand to hold down theworkpiece.
• Keep arms, hands and fingers away from the blade to
prevent seriousinjury.
• Use a push stick that is appropriate to the application
to push workpieces through the saw. A push stick is a
wooden or plastic stick, often homemade, that should be used
whenever the size or shape of the workpiece would cause you
to place your hands within 152mm of theblade.
• Use hold-downs, jigs, fixtures or feather boards to help
guide and control the workpiece. Accessories for use with
your tool are available at extra cost from your local dealer or
authorized service centre.
• Do not perform ripping, crosscutting or any other
operationfreehand.
• Never reach around or over sawblade while the blade
isspinning.
• Stability. Make sure the table saw is firmly mounted to a
secure surface before use and does notmove.
• The table saw should only be set up on a level and stable
surface. The work area should be free from obstructions and
trip hazards. No materials or tools should be leaned against
thesaw.
• Never cut metals, cement board or masonry. Certain
man-made materials have special instructions for cutting on
table saws. Follow the manufacturer’s recommendations at all
times. Damage to the saw and personal injury mayresult.
• Do not install a diamond masonry blade and attempt to use
the table saw as a wetsaw.
• The proper throat plate must be locked in place at all
times to reduce the risk of a thrown workpiece and
possibleinjury.
• Wear gloves when handling sawblades.
• Use the correct saw blade for the intended operation.
The blade must rotate toward the front of the saw. Always
tighten the blade arbor nut securely. Before use, inspect the
blade for cracks or missing teeth. Do not use a damaged or
dullblade.
• Never attempt to free a stalled saw blade without first
turning the machine off and disconnect tool from power
source.If a workpiece or cut-off piece becomes trapped inside
the blade guard assembly, turn saw off and wait for blade to
stop before lifting the blade guard assembly and removing
thepiece.
• Never start the machine with the workpiece against
the blade to reduce the risk of a thrown workpiece and
personalinjury.
• Do not have any part of your body in line with the blade.
Personal injury may occur. Stand to either side of theblade.
• Never perform layout, assembly or set-up work on the
table/work area when the machine is running. A sudden
slip could cause a hand to move into the blade. Severe injury
canresult.
• Never perform any adjustments while the saw is running
such as fence repositioning or removal, bevel lock
adjustment, or blade heightadjustment.
• Clean the table/work area before leaving the machine.
Lock the switch in the “OFF” position and disconnect tool from
power source to prevent unauthorizeduse.
• Always lock the fence and bevel adjustment
beforecutting.
• Avoid overheating the saw blade tips. Keep material
moving and parallel with the fence. Do not force work into
theblade.
• If cutting plastic materials, avoid melting theplastic.
• Do not leave a long board (or other workpiece)
unsupported so the spring of the board causes it to shift
on the table resulting in loss of control and possible
injury. Provide proper support for the workpiece, based on its
size and the type of operation to be performed. Hold the work
firmly against the fence and down against the tablesurface.
• If this saw makes an unfamiliar noise or if it vibrates
excessively, cease operating immediately, turn unit
off and disconnect tool from power source until the
problem has been located and corrected. Contact a
DeWALT
factory service centre, a
DeWALT
authorized service
centre or other qualified service personnel if the problem can
not befound.
• Do not operate this machine until it is completely
assembled and installed according to the instructions. A
machine incorrectly assembled can cause seriousinjury.
• Never attempt to cut a stack of loose pieces of material
which could cause loss of control or kickback. Support all
materialssecurely.
Saw Blades
WARNING: to minimise the risk of kickback and to ensure
proper cutting, the splitter and riving knife must be the
proper thickness for the blade used. If a different blade
is used, check the blade body (plate) thickness and the
blade kerf (cutting) width marked on the blade or on the
blade packaging. The splitter and riving knife thickness
must be greater than the body thickness and less than the
kerfwidth.
• Do not use saw blades that do not conform to the dimensions
stated in the Technical Data. Do not use any spacers to make
a blade fit onto the spindle. Use only the blades specified in this
manual, complying with EN847-1, if intended for wood and
similarmaterials.
• Consider applying specially designed noise-reductionblades.
• Do not use high steel (HS) sawblades.
• Do not use cracked or damaged sawblades.
• Ensure that the chosen saw blade is suitable for the material
to becut.
• Always wear gloves for handling saw blades and rough
material. Saw blades should be carried in a holder
whereverpracticable.

ENGLISH
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 saw blade with
unprotectedhands.
• 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 are of influence to noise production:
• the material to be cut
• the type of saw blade
• the feed force
• machine maintenance
The following factors are of influence to dust exposure:
• worn saw blade
• dust extractor with air velocity less than 20 m/s
• workpiece not exactly guided
Electrical Safety
The electric motor has been designed for one voltage only.
Always check that the power supply corresponds to the voltage
on the ratingplate.

Bench Mounting (Fig. A, B)
CAUTION: To reduce the risk of personal injury, make sure
table saw is firmly mounted to a stable surface beforeuse.
CAUTION: Ensure that the surface is stable enough
that large pieces of material will not cause it to tip over
duringuse.
The table saw must be mounted firmly. Four holes9 are
provided in the tool’s base for mounting. We strongly
recommend that these holes be used to anchor the table saw to
your workbench or other stationary rigidframe.
1. Centre the saw on a square piece of 12.7mmplywood.
2. Mark the positions of the two rear mounting holes(spaced
220 mm apart) in the frame of the saw with a pencil. Then
measure forward 498.5 mm for the two front holes spaced
230 mmapart.
3. Remove the saw and drill 9 mm holes in the places you have
justmarked.
4. Position the saw over the four holes you drilled in the
plywood and insert four 8mm machine screws FROM
THE BOTTOM. Install washers and 8mm nuts on the top.
Tightensecurely.
5. In order to prevent the screw heads from marring the
surface to which you clamp the saw, attach two strips of
scrap wood to the bottom of the plywood base. These strips
can be attached with wood screws installed from the top
side as long as they don’t protrude through the bottom of
thestrip.
6. Use a “C” clamp to secure the plywood base to your
workbench whenever you use thesaw.
ADJUSTMENTS
Blade Adjustment (Fig. H)
Blade Alignment (Parallel to Mitre Slot)
WARNING: Cut Hazard. Check the blade at 0˚ and 45˚
to make sure blade does not hit the throat plate, causing
personalinjury.
If the blade appears to be out of alignment with the mitre slot
on the table top, it will require calibration for alignment. To
realign the blade and mitre slot, use the following procedure:
WARNING: To reduce the risk of injury, turn unit
off and disconnect machine from power source
before installing and removing accessories, before
adjusting or changing set-ups or when making
repairs. An accidental start-up can causeinjury.
1. Using a 5mm hex wrench, loosen rear pivot bracket
fasteners32, located on the underside of the table, just
enough to allow the bracket to move side-to-side.
2. Adjust the bracket until the blade is parallel to the mitre
gaugeslot.
3. Tighten the rear pivot bracket fasteners to 12.5–13.6 Nm
(110–120 in-lbs).
Blade height adjustment(Fig.A)
The blade can be raised and lowered by turning the blade
height adjustment wheel6.
Make sure the top three teeth of the blade are just breaking
through the upper surface of the workpiece when sawing. This
will ensure that the maximum number of teeth are removing
material at any given time, thus giving optimumperformance.
Aligning Guard Assembly/Splitter to
Blade (Fig. A, B, I)
1. Remove the throat plate. Refer to Remove ThroatPlate.
2. Raise the blade to full depth of cut and 0° bevelangle.
3. Locate the three small set screws39 adjacent to the guard
assembly lock shaft38. These screws will be used to adjust
the guard assemblyposition.
4. Lay a straight edge on the table against two blade tips. The
splitter13 should not touch the straight edge. If needed,
loosen the two larger lock screws41.
5. Adjust the small set screws39 to move the splitter
according to the position noted in step 4. Lay the straight
edge on the opposite side of the blade and repeat
adjustments asneeded.
6. Lightly tighten the two larger lock screws41.
7. Place a square flat against the splitter to the verify splitter is
vertical and in-line with theblade.

rip fence. This adjustment has been made at the factory. To
re-adjust:
Position 1 Fence Alignment
1. Install the fence in position 1 and unlock the rail lock
lever5. Locate both locator pins29 that support the fence
on the front and rearrails.
2. Loosen the rear locator pin screw and adjust the alignment
of the fence in the groove until the fence face is parallel to
the blade. Make sure you measure from the fence face to
the front and back of the blade to ensurealignment.
3. Tighten the locator screw and repeat on the left side of
theblade.
4. Check rip scale pointer adjustment(Fig.K).
Position 2 Fence Alignment
1. To align position 2 fence locator pins29, ensure
position 1 pins have been aligned, refer to Position 1
FenceAlignment.
2. Loosen the position 2 pins, then using the blade wrench
holes as a guide for positioning, align the pins(Fig.Q).
3. Tighten the locator pins(front and rear).
Adjusting the Rip Scale (Fig. A, K)
1. Unlock the rail lock lever5.
2. Set the blade at 0° bevel and move the fence in until it
touches theblade.
3. Lock the rail locklever.
4. Loosen the rip scale indicator screws31 and set the rip
scale indicator to read zero(0). Retighten the rip scale
indicator screws. The yellow rip scale(top) reads correctly
only when the fence is mounted on the right side of
the blade and is in position 1(for zero to 62 cm ripping)
not the 82.5 cm rip position. The white scale(bottom)
reads correctly only when the fence is mounted on the
right side of the blade and in position 2(for 20.3 cm to
82.5cmripping).
The rip scale reads correctly only when the fence is mounted to
the right of theblade.
Rail Lock Adjustment (Fig. A, L)
The rail lock has been factory-set. If you need to re-adjust,
proceed as follows:
1. Lock the rail lock lever5.
2. On the underside of the saw, loosen the jam nut33.
3. Tighten the hex rod34 until the spring on the locking
system is compressed creating the desired tension on the
rail lock lever. Retighten the jam nut against the hexrod.
4. Flip the saw over and check that the fence does not move
when the lock lever is engaged. If the fence is still loose,
tighten the springfurther.
Bevel Stop and Pointer Adjustment (Fig. M)
1. Raise the blade fully by rotating the blade height
adjustment wheel6 clockwise until itstops.
2. Unlock the bevel lock lever7 by pushing it up and to the
right. Loosen the bevel stop screw36.
3. Place a square flat against the table top and against the
blade between teeth. Ensure the bevel lock lever is in its
unlocked, or upposition.
4. Using the bevel lock lever, adjust the bevel angle until the
blade is flat against thesquare.
5. Tighten the bevel lock lever by pushing itdown.
6. Turn the bevel stop cam35 until it firmly contacts the
bearing block. Tighten the bevel stop screw36.
7. Check the bevel angle scale. If the pointer does not read 0°,
loosen pointer screw37 and move the pointer so it reads
correctly. Retighten the pointerscrew.
8. Repeat at 45°, but do not adjustpointer.
