3. General safety rules

1. WARNING!
Read and understand all instructions.

Failure to follow all instructions listed below may
result in electric shock, fire and/or serious personal
injury.

SAVE THESE INSTRUCTIONS

2. Work Area

2.1 Keep your work area clean and well lit. Clut­tered benches and dark areas invite accidents.

2.2 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.

2.3 Keep bystanders, children and visitors away
while operating a power tool. Distractions can
cause you to lose control.

tention while operating power tools may result in
serious personal injury.

4.2 Dress properly. Do not wear loose clothing or

jewelry. Contain long hair. Keep your hair, cloth­ing, and gloves away from moving parts. Loose

clothes, jewelry, or long hair can be caught in mov­ing parts.

4.3 Avoid accidental starting. Be sure switch is off
before plugging in. Carrying tools with your finger
on the switch or plugging in tools that have the
switch on invites accidents.

4.4 Remove adjusting keys or wrenches before
turning the tool on. A wrench or a key that is left
attached to a rotating part of the tool may result in
personal injury.

4.5 Do not overreach. Keep proper footing and bal-
ance at all times. Proper footing and balance
enables better control of the tool in unexpected situ­ations.

3. Electrical Safety

3.1 Double Insulated tools are equipped with a polar­ized plug (one blade is wider than the other.) This
plug will fit in a polarized outlet only one way. If the
plug does not fit fully in the outlet, reverse the plug.
If it still does not fit, contact a qualified electrician to
install a polarized outlet. Do not change the plug in
any way. Double Insulation Z eliminates the need for

the three wire grounded power cord and grounded power
supply system. Applicable only to Class II tools.

3.2 Avoid body contact with grounded surfaces
such as pipes, radiators, ranges and refrigerators.

There is an increased risk of electric shock if your
body is grounded.

3.3 Do not expose power tools to rain or wet con-
ditions. Water entering a power tool will increase
the risk of electric shock.

3.4 Do not abuse the cord. Never use the cord to

carry the tools or pull the plug from an outlet.
Keep cord away from heat, oil, sharp edges or
moving parts. Replace damaged cords immedi­ately. Damaged cords increase the risk of electric

shock.

3.5 When operating a power tool outside, use an

outdoor extension cord marked «W-A» or «W».

These cords are rated for outdoor use and reduce
the risk of electric shock.

4. Personal Safety

4.1 Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a tool while tired or under the influence of
drugs, alcohol, or medication. A moment of inat-

4.6 Use safety equipment. Always wear eye pro­tection. Dust mask, non-skid safety shoes, hard hat

or hearing protection must be used for appropriate
conditions.

5. Tool Use and Care

5.1 Use clamps or other practical way to secure
and support the workpiece to a stable platform.

Holding the work by hand or against your body is
unstable and may lead to loss of control.

5.2 Do not force tool. Use the correct tool for your
application. The correct tool will do the job better
and safer at the rate for which it is designed.

5.3 Do not use tool if the switch does not turn it on
or off. Any tool that cannot be controlled with the
switch is dangerous and must be repaired.

5.4 Disconnect the plug from the power source be-

fore making any adjustments, changing acces­sories, or storing the tool. Such preventive safety

measures reduce the risk of starting the tool acci­dentally.

5.5 Store idle tools out of reach of children and
other untrained persons. Tools are dangerous in
the hands of untrained users.

5.6 Maintain tools with care. Keep cutting tools
sharp and clean. Properly maintained tools with
sharp cutting edges are less likely to bind and are
easier to control.

5.7 Check for misalignment or binding of moving

parts, breakage of parts and any other condition
that may affect the tools operation. If damaged,

Printed: 07.07.2013 | Doc-Nr: PUB / 5071326 / 000 / 00

have the tool serviced before using. Many acci­dents are caused by poorly maintained tools.

5.8 Use only accessories that are recommended
by the manufacturer for your model. Accessories
that may be suitable for one tool may become haz­ardous when used on another tool.

6. Service

6.1 Tool service must be performed only by quali­fied repair personnel. Service or maintenance per-

formed by unqualified personnel could result in a risk
of injury.

6.2 When servicing a tool, use only identical

replacement parts. Follow instructions in the Main­tenance section of this manual. Use of unauthorized

parts or failure to follow Maintenance Instructions
may create a risk of electric shock or injury.

4. Specific safety rules

G DANGER! Keep hands away from cutting area and
blade. Keep your second hand on auxiliary handle, or
motor housing. If both hands are holding the saw, they

cannot be cut by the blade.

G Keep your body positioned to either side of the saw
blade, but not in line with the saw blade. KICKBACK

could cause the saw to jump backwards (see ”Causes
and Operator Prevention of Kickback”).
G Do not reach underneath the work. The guard can
not protect you from the blade below the work.

G Check lower guard for proper closing before each
use. Do not operate saw if lower guard does not move
freely and close instantly. Never clamp or tie the low­er guard into the open position. If saw is accidentally

dropped, lower guard may be bent. Raise the lower guard
with the Retracting Handle and make sure it moves freely
and does not touch the blade or any other part, in all
angles and depths of cut.

G Check the operation and condition of the lower guard
spring. If the guard and the spring are not operating
properly, they must be serviced before use. Lower

guard may operate sluggishly due to damaged parts,
gummy deposits, or a buildup of debris.

G Lower guard should be retracted manually only for
special cuts such as ”Pocket Cuts” and ”Compound
Cuts”. Raise lower guard by Retracting Handle. As
soon as blade enters the material, lower guard must
be released. For all other sawing, the lower guard should

operate automatically.

G Always observe that the lower guard is covering the
blade before placing saw down on bench or floor. An

unprotected, coasting blade will cause the saw to walk
backwards, cutting whatever is in its path. Be aware of
the time it takes for the blade to stop after switch is
released.

Printed: 07.07.2013 | Doc-Nr: PUB / 5071326 / 000 / 00

G NEVER hold piece being cut in your hands or across
your leg. It is important to support the work properly to

minimize body exposure, blade binding or loss of con­trol.

G Hold tool by insulated gripping surfaces when per­forming an operation where the cutting tool may con­tact hidden wiring or its own cord. Contact with a ”live”

wire also make exposed metal parts of the tool ”live” and
shock the operator.

G When ripping always use a rip fence or straight edge
guide. This improves the accuracy of cut and reduces

the chance for blade binding.

G Always use blades with correct size and shape (dia­mond vs. round) arbor holes. Blades that do not match

the mounting hardware of the saw will run eccentrical­ly, causing loss of control.

G Never use damaged or incorrect blade washers or
bolts. The blade washers and bolt were specially designed

for your saw, for optimum performance and safety of
operation.

Causes and Operator Prevention of Kickback:

– Kickback is a sudden reaction to a pinched, bound or

misaligned saw blade, causing an uncontrolled saw
to lift up and out of workpiece toward the operator.

– When the blade is pinched or bound tightly by the kerf

closing down, the blade stalls and the motor reaction
drives the unit rapidly back toward the operator.

– If the blade becomes twisted or misaligned in the cut,

the teeth at the black edge of the blade can dig into the
top surface of the wood causing the blade to climb out
of the kerf and jump back toward operator.

– Kickback is the result of tool misuse and/or incorrect

operating procedures or conditions and can be avoid­ed by taking proper precautions as given below:

G Maintain a firm grip with both hands on the saw and
position your body and arm to allow you to resist KICK­BACK forces. KICKBACK forces can be controlled by the

operator, if proper precautions are taken.

G When blade is binding, or when interrupting a cut
for any reason, release the trigger and hold the saw
motionless in the material until the blade comes to a
complete stop. Never attempt to remove the saw from
the work or pull the saw backward while the blade is
in motion or KICKBACK may occur. Investigate and take

corrective actions to eliminate the cause of blade bind­ing.

G When restarting a saw in the workpiece, center the
saw blade in the kerf and check that saw teeth are not
engaged into the material. If saw blade is binding, it

may walk up or KICKBACK from the workpiece as the
saw is restarted.

G Support large panels to minimize the risk of blade
pinching and KICKBACK.

under their own weight. Supports must be placed under
the panel on both sides, near the line of cut and near the
edge of the panel.
G Do not use dull or damaged blade. Unsharpened or
improperly set blades produce narrow kerf causing exces­sive friction, blade binding and KICKBACK.

Large panels tend to sage

G Blade depth and bevel adjusting locking levers must
be tight and secure before making cut. If blade adjust-

ment shifts while cutting, it may cause binding and KICK­BACK.

G Use extra caution when making a ”Pocket Cut” into
existing walls or other blind areas. The protruding blade

may cut objects that can cause KICKBACK.

G Always disconnect the supply cord plug from the mains
socket before disassembling or adjusting the tool.
G Do not switch the tool on before it has been brought
into position where the cut is to be made.
G Do not overload the tool.

Cutting along a line

A cutting line indicator (0° / 22.5° / 45°), is located on
the front section of the baseplate of the tool. This permits
precise cuts to be made at the selected cutting angle. The
viewing grill provides a better view of the cutting line,
thus making it easier to check the progress of the cut.
If required, the cutting depth can be pre-set to any value
within the 0–65 mm (0–2
Best results will be obtained when the saw blade projects
approx. 5–10 mm (

5

/8″) depth range.

1

/4–1/2″) beyond the underside of the
workpiece.
G Check that the control switch on the tool is in the OFF
position.

G Connect the supply cord plug to the mains socket.

G Position the tool with the baseplate on the workpiece

so that the saw blade is not in contact with the workpiece.
G Switch the tool on by pressing the switch interlock
and the on/off switch.
G Guide the saw at a suitable speed through the work­piece while following the cutting line.

Mitre cuts

Adjusting the cutting angle

G Release both cutting angle clamping levers.
G Pivot the mechanism until the desired cutting angle

of 0°–45° is indicated by the cutting angle scale.

G Retighten both clamping levers.
G Make the cut while observing the cutting line indica-

tor at the front section of the baseplate.

Returning the saw to the 0° position
G Clean the baseplate to remove wood chips or other
foreign material from the pivoting section before return­ing the saw to its original position.

Plunge cutting

To reduce the risk of kick-back when starting a plunge
cut, a wooden batten or similar stop should be securely
fastened to the workpiece behind the rear of the tool
baseplate.
When cutting to the full depth, the length of the cut can
be checked at the plunge cut marks located on the baseplate.

G Check that the switch on the tool is in the OFF position.
G Connect the supply cord plug to the mains socket.
G Place the tool on a suitable surface.
G Release the cutting depth locking lever.

beginning sawing by measuring the projection of the saw
blade from the baseplate.

Constant speed electronics / speed pre-selection

The WSC 267-E is equipped with constant speed elec­tronics.
The speed regulator can be used to adjust the speed of
the saw blade to any value within the 2200–4300 r.p.m.
range. The numbers on the speed regulator represent the
following approximate saw blade speeds:

1 2200 r .p.m.
2 2600 r .p.m.
3 3000 r .p.m.
4 3500 r .p.m.
5 3900 r .p.m.
6 4300 r .p.m.

The built-in constant speed electronics maintain the pre­selected speed at an almost constant level even when the
tool is under load. The recommended speeds and infor­mation concerning choice of the correct saw blade can
be found in the product information and corresponding
table of applications.

Smooth starting

The tool is equipped with a starting current limitation
device which ensures optimum working comfort. The
tool thus starts and runs up to speed without an unpleas­ant jolt.

motor side, so that the saw blade faces upwards and is
easily accessible.
G Release the clamping sccccrew and clamping flange
by turning in a counter-clockwise direction.
G Use the manual control to swing the pivoting guard
back and remove the saw blade.
G Clean the saw blade contact surfaces to remove wood
chips and other foreign material.
G Check again that the data for the saw blade complies
with the information given in these operating instruc­tions.
G The saw blade must meet the specification for the tool
with regard to spindle speed, spindle size and shape, disc
core thickness, kerf width and blade diameter.

Use of other saw blades is not permissible.

G When fitting the new saw blade, take care to ensure
that the direction of rotation arrow on the saw blade cor­responds to the direction of rotation arrow on the guard.

G Check that the saw blade is seated correctly.
G Use the wrench included to tighten the clamping screw

and flange securely in a clockwise direction.

G Stand the tool on its baseplate.
G Bring the clamping lever back to its original position.

The following design aspects were incorporated in the
tool for more safety when changing saw blades:

G The clamping lever cannot be opened when the switch
interlock is depressed, i.e. when the tool is running.
G The switch interlock cannot be depressed when the
clamping lever is open, i.e. the tool cannot be started.
G Do not attempt to overcome the interlock by using
tools or applying excessive force.

9. Care and maintenance

Care

G Used saw blades should be cleaned to remove resin
deposits at regular intervals as clean blades achieve a
much higher cutting performance. Resin deposits can
be removed by placing the saw blades in a bath of petro­leum (paraffin, kerosene) or commercially available resin
remover.
G Carbide-tipped circular saw blades
must no longer be used when the
remaining height or thickness of the
brazed-on tips is less than 1 mm

1

(

/16″).
G The tool was lubricated adequately when it was man­ufactured. After long periods of heavy use, it is recom­mended that the tool is inspected at a Hilti repair center.
This will increase the life expectancy of the tool and avoid
unnecessary repair costs.
G Repairs to the electrical section of the tool may be car­ried out only by a trained electrical specialist.

CAUTION
Keep the power tool, especially its grip surfaces, clean
and free from oil and grease. Do not use cleaning
agents which contain silicone.

The outer casing of the power tool is made from impact­resistant plastic. Sections of the grip are made from a
synthetic rubber material.
Never operate the power tool when the ventilation slots
are blocked. Clean the ventilation slots carefully using
a dry brush. Do not permit foreign objects to enter the
interior of the power tool. Clean the outside of the pow­er tool at regular intervals with a slightly damp cloth. Do

not use a spray, steam pressure cleaning equipment or
running water for cleaning. This may negatively affect
the electrical safety of the power tool.

Maintenance

Regularly check all external parts of the tool for damage
and check that all controls operate faultessly. Don’t oper­ate the tool when parts are damaged or when the con­trols do not function faultessly. Have your tool repaired
by a Hilti service center.

Repairs to the electrical selections of the tool may be
carried out only by trained electrical specialists.

10. Accessories

Guides

Sawing using the parallel guide

G The parallel guide (accessory) is used to make precise
cuts along the edge of the workpiece, thus making it pos­sible to cut strips of even width. In addition, it can be
used as an extension to the saw baseplate.

Fitting the parallel guide 

G When fitting the parallel guide, better access can be
achieved by releasing the cutting depth locking lever and
raising the tool as far as it will go. The locking lever should
then be re-engaged to lock the tool at its maximum height.
G Insert the hex. screws through the holes in the base­plate from the contact surface side so that the threaded
sections of the screws are visible from above
G Place the pressure springs and then the clamping
plates on the screws.
G Screw the hex. nuts onto the screws. Do not tighten
the nuts.
G Slide the rods of the parallel guide into the guide chan­nels provided in the baseplate until they are under the
clamping plates.

G Tighten the hex. nuts by hand until they are free of play.
G Push the clamping lever onto the hex. nut while press-

ing the tab located on the inside of the lever. This should
be done so that the concave surface of the lever faces to
the right and the hex. nut is thus tightened when the
clamping lever is brought into the closed position.
G The parallel guide can now be fixed in position by turn­ing the clamping levers. If a secure hold cannot be obtained
by turning the clamping levers, the clamping levers should
be removed from the nuts, repositioned, and then re-tight­ened. The clamping levers can be removed by pressing
the tab positioned on the inside of the lever. Replace the
clamping levers as previously described (at the outset posi­tion or in the middle, depending on the clamping move­ment necessary) and then tighten the levers securely.

Printed: 07.07.2013 | Doc-Nr: PUB / 5071326 / 000 / 00

G The parallel guide can be removed at any time by releas­ing the clamping levers (the clamping levers and other
clamping parts may remain attached to the tool).

Using the parallel guide

G Release both clamping levers.
G Slide the guide to the desired position (dimension)
G Tighten the clamping levers securely.

The cutting dimension between the circular saw blade
and the parallel guide can be pre-set by making use of
the two notches in the guide rods and the correspond­ing scale. The parallel guide can be fitted on either side
of the baseplate. When reversed (edge of the guide fac­ing upwards), the parallel guide serves as an extension
to the baseplate.

Sawing using the guide rail 

The guide rail is designed for making precise mitre cuts
at up to 45° and cuts across the surface of the work­piece at angles of up to 60°. The guide rail must be in
faultless condition in order to ensure good results. The
non-slip strips located on the underside prevent the rail
slipping out of position and also protect the surface of
the workpiece. It is, however, recommended that screw
clamps are used to secure the guide rail. All parts are
manufactured from materials which ensure smooth oper­ation. The cut is made approx. 1 mm from the edge of
the rail at all angle settings. Use of the guide rail reduces
the set cutting depth by approx. 5 mm. The tool must
be placed on the guide rail so that the rail profile and the
channel in the baseplate of the tool correspond and thus
provide a smooth guide. Two adjustable play compen­sators are provided on the baseplate of the circular saw.
These can be used to adjust play between the circular
saw and the guide rail, thus ensuring optimum guid­ance.

Cutting / trimming

G Use two screw clamps fitted from below to attach the
rail so that the section of the rail for positioning the tool
projects beyond the workpiece.
G Position the tool on the corresponding section of the
guide rail and ensure that the saw blade is not in contact
with the workpiece.
G Switch the tool on and slide it evenly towards the work­piece. The pivoting guard opens when it contacts the
edge of the rail and closes again when the saw is pushed
off the far end of the guide rail.

Cuts at an angle across the surface of the workpiece

G Position the guide rail with the zero mark at the edge
of the workpiece and pivot the rail until the desired angle
shown on the angle scale is opposite zero.
G Use two screw clamps to secure the guide rail in this
position and then make the cut as described above. The
cutting angle indicated is the angle of deviation from a
straight, right-angled cut.

Plunge cutting

G Use two screw clamps to fasten the guide rail to the
workpiece.

9

G Lock the tool at the maximum cutting height position
and use the manual control to open the pivoting guard.
G Place the tool on the guide rail, taking care to ensure
that the baseplate lies flat on the rail.
G Use the stop piece to increase safety when making the
plunge cut. It should be fixed in position at the rear edge
of the baseplate so that the rear plunge cut mark on the
circular saw coincides with the point at which the cut is
to begin.
G Set the cutting depth to maximum depth unless a pre­defined cutting depth is required.
G Switch the tool on and plunge the blade evenly into
the workpiece.

External dust and chip extraction

Extraction of dust and chips reduces the amount of dust
in the working environment and helps to keep the work­place clean. Connect the external extraction system when
you are using the saw for a long period or when work­ing with materials which produce harmful dust when cut.
The hand-held circular saw is equipped with a hose con­nector suitable for use with conventional extraction hoses
with a diameter of ≥ 27 mm (1

3

/8″). The direction of chip
ejection can be selected simply by turning the pivoting
chip ejector until it engages in the desired position.

Cleaning the chip ejection channel

G Ensure that the tool is disconnected from the mains
socket.
G Press the plastic tab on the rear lower side of the guard
and remove the guard.
G Clean the chip ejection channel in the guard and then
replace the guard, ensuring that the plastic tab is engaged.

Ensure that only a safety vacuum cleaner of the “M” class
(wood) is used and that its equipment is of the anti-sta­tic type. We recommend use of the Hilti WVC 40-M safe­ty vacuum cleaner.
