Warning! The use of any accessory or
attachment, other than recommended in
this instruction manual, may present a risk
of personal injury.
Warning! Your saw is designed for
use with wood cutting blades with a max
operating speed above 4800 RPM.
Warning! Do Not use blades with a
Max operating speed below this speed.
Do not use saw blades which are deformed
or cracked.
Do not use saw blades made from High
Speed Steel.
Do not use saw blades which do not
comply with the characteristics specified
within this manual.
Do not stop the saw with lateral pressure on
the blade.
Do not lock the moveable guard in the open
Ensure the moveable guard operates freely
without jamming.
Always ensure the retraction mechanism of
the guard operates correctly prior to using
the saw each time.

the mains supply before making any
adjustments or maintenance to the saw.
Preparing Your Saw
Setting the Depth of Cut.
Remove the plug of the saw from the electricity
Unlock the depth of cut lock adjustment by
lifting the depth of cut locking lever.
The depth of cut can now be adjusted by lifting
the rear section of the saw body.
Depth of Cut
A scale referring to the depth of cut is provided
as a guide. It is located between the top guard
and the rear handle.
Note, the scale is a guide only and where an
accurate depth of cut is required, the actual
depth of cut should be measured with a rule.
the desired
setting is achieved, lock the
depth of cut adjustment by pushing the depth
of cut locking lever downwards.
Where the saw blade is required to cut fully
through the work piece, the blade should be
set to a depth of cut 3 - 5 mm greater than the
work piece.
Fitting and Adjusting the Parallel
Your CS718 Circular Saw includes a parallel
fence. This assists in the sawing of a straight
line, parallel to the edge of the work piece.
To fit and adjust the parallel fence proceed as
Remove the plug of the saw from the
electricity supply.
Loosen the parallel locking screw at the front of
the saw shoe.
Slide the parallel fence into the slot under the
locking screw.
Slide the parallel fence towards the cutting
blade until the desired measurement is
obtained between the tooth of the cutting blade
and the inner edge of the parallel fence.
To ensure the correct setting, always make a
test cut on a scrap piece of timber to ensure
the parallel fence has been correctly set to the
measurement you require.

Fit the outer flange ensuring the flange is clean.
Fit the blade locking screw and washer and
engage the spindle lock. Tighten the locking
screw by rotating with the hex spanner in a
clockwise direction.
Changing the Blade
Before fitting any blade to the circular saw
ensure the max safe working speed of the
blade is above 4800RPM.
Remove the plug of the saw from the electricity
supply. Never attempt to change the blade
while the circular saw is plugged into the
electricity supply.

The CS718 Circular Saw is designed to fit the
following blade.
184mm (71/4”)
Bore diameter
No load speed (min)
4800 RPM
Important: The No Load Speed of the saw is
4800 RPM. The saw blade to be fitted must be
rated higher than 4800 RPM.
Workpiece Support
Replacement blades are available from
Black & Decker.
Operating the Circular Saw
The above diagram shows proper sawing
position. Note that the hands are kept away
from the cutting area.
Warning! It is important to support the
work properly and to hold the saw firmly to
prevent loss of control which could cause
personal injury.
Place the work with the good side, the one on
which appearance is most important – down.
The saw cuts upward, so any splintering will
be on the work face that is up when you saw it.
Lock off
To operate the circular saw, ensure the plug is
connected PIC.
to a standard
electrical outlet with
the switch turned on.
To turn the saw “On”, depress the small lock
off button on the side of the handle and then
squeeze the On/Off trigger .
To stop the saw, release the trigger switch.
Improper Support
Holding the Circular Saw
It is important when operating
the circular saw
that the operator is always in complete control.
The saw is fitted with two handles, one at
the rear and one at the front. It is always
recommended to use both handles when using
the saw.
The front handle is positioned to guide the saw
along the path to be cut.
A. Sagging or improper lifting of the cut off
piece will cause pinching of the blade.
B. Cutting through material supported at the
outer ends only. As the material weakens
it sags, closing the kerf and pinching the
C. Cutting off a cantilevered overhanging piece
of material from the bottom in a vertical
direction. The falling cut-off piece can pinch
the blade.
D. Cutting off long narrow strips (as in
ripping). The cut off strip can sag or twist
closing the kerf and pinching the blade.
E. Snagging the lower guard on a surface
below the material being cut can
momentarily reduce operator control.
The saw can lift partially out of the cut
increasing the chance of blade twist.
C. Pressure treated timber (material treated
with preservatives or anti-rot chemicals).
Use of Dull or Dirty Blades
Dull blades cause increased loading of the
saw. To compensate, an operator will usually
push harder which further loads the unit and
promotes the twisting of the blade in the kerf.
Worn blades may also have insufficient body
clearance which increases the chance of
binding and increased loading.
To minimise the splintering:
Improper Depth of Cut Setting on the Saw
Do not force the saw.
Cut from the opposite side if possible.
Clamp a thin piece of scrap over the top of the
material to be cut. Cut through both the scrap
and the original work piece.
Do not overload the saw. Allow the saw to run
at close to full speed during operation. Do not
force the saw into the work piece. The tool will
cut better when the saw is running at close to
full speed.
In the event where the saw has been used in a
heavy application, or if the saw appears to be
hot, run the saw for two minutes unloaded to
allow the motor to cool. Always ensure the air
intake vents are clear.
Using the saw with an excessive depth of cut
setting increases loading on the unit and susceptibility to twisting of the blade in the kerf.
It also increases the surface area of the blade
available for pinching under conditions of kerf
close down.
Blade Twisting
(Misalignment in Cut)
A. Pushing harder to cut through a knot, a nail
or a hard grain area can cause the blade to
B. Trying to turn the saw in the cut (trying to
get back on the marked line) can cause
blade twist.
C. Extended reach or operating saw with poor
control (operator off balance), can result in
twisting the blade.
D. Changing hand grip or body position while
cutting can result in blade twist.
E. Backing unit up to clear blade can lead to
twist if not done carefully.
Kick Back
When the blade is pinched or bound tightly
by the kerf closing down, the blade stalls
and the motor reaction drives the unit rapidly
backwards towards the operator.
If the blade becomes twisted or misaligned
in the cut, the teeth at the back edge of the
blade can dig into the top surface of the wood
causing the blade to climb out of the kerf and
jump backwards towards the operator.
Using dull blades or improperly supported
work will increase the tendency for kickback.
Wet timber, green timber or pressure treated
Materials that Require Extra Attention
A. Wet timber.
B. Green timber (material freshly cut or not kiln
timber require special attention during cutting
operation to prevent kickback.
Line Guide
The right side of the notch in the front of the
shoe is the guide for straight 90 degree cuts.
The left side of the notch is for 45 degree
bevel cuts. The cutting guide notch gives an
approximate line of cut since different blade
types and thickness alter the line cut. Always
make sample cuts in scrap timber to obtain the
actual line cut. To minimize splintering, cut the
good side down.
General Cuts
When starting a cut always hold the saw
handle with one and and the front handle with
the other. Never force the saw but maintain a
light and continuous pressure.
After completing the cut, allow the saw to
come to a complete stop. When cutting is
interrupted, resume cutting by allowing the
blade to reach full speed and then re-entering
the cut slowly.
When cutting across the grain, the fibres of
the wood have a tendency to lift and tear.
Moving the saw slowly minimises this effect.
Pocket Cuts
Disconnect the plug from the power supply
before making any adjustments. Set the depth
adjustment based on the thickness of the
material to be cut. Tilt the saw forward with
the cutting guide notch on the line drawn for
the cut. Raise the lower guard by using the lift
lever. With the blade barely above the material
to be cut, start the saw and allow the blade to
come to full speed. Gradually lower the blade
into the material being cut using the front end
of the shoe as a pivot point. When the blade
starts cutting, release the lower guard. When
the shoe is resting flat on the surface being
cut, proceed cutting in a forward direction to
the end of the cut. Allow the blade to come to a
full stop before removing it form the cut. Never
pull the saw backward since the blade will
climb out of the cut and kick back will occur.
Turn the saw around and finish the cut in a
normal manner, sawing forward. Use a jigsaw
or a handsaw to finish the cut in the corners, if
1. All bearings are sealed. They are lubricated
for life and need no further maintenance.
2. The brushes are designed to give you
several years of use. If they ever need
replacement return the tool to the nearest
service centre for repair.
To assure product SAFETY and RELIABILITY,
repairs, maintenance and adjustment including
brush inspection and replacement) should be
performed by authorised service centres or
other qualified service organisations, always
using identical replacement parts.
