of the workpiece. Less than a full tooth height
should be visible below the workpiece.
d. Never hold the workpiece in your hand or
steady it with your leg whilst sawing. Keep
the workpiece steady on a stable supporting
surface. It is important to see that the workpiece
is firmly held in place to minimise any danger of
it making contact with your body, jamming of the
saw blade or loss of control.
e. Hold the device by the insulated handle sur-
faces when you are undertaking work where
there is the danger of the cutting tool strik-
ing hidden electricity cables or the device's
mains lead. Contact with a live wire means that
the metal parts of the device may also become
live and this can result in an electric shock.
f. When cutting longitudinally always use a
guide fence or a straight edge guide. This will
improve the accuracy of your cut and reduce the
risk of the blade jamming.
g. Always use a saw blade of the correct size
and with the appropriate central fixing hole
bore. Saw blades that do not correspond with the
attachment components on the saw will not run
true and could lead to loss of control.
h. Never use a damaged or incorrect saw blade
washer or screw. The saw blade washer and
screw have been specially designed to give your
saw optimum performance and safety in use.
To avoid the device kicking back:
Kickback occurs as a result of incorrect use or mis-
use of the saw. It can be prevented by taking the ap-
propriate precautions as described below.
a. Hold the saw with both hands and bring your
arms into a position in which you will be able
to withstand any kickback forces. Always
stand to the side of the saw blade and nev-
er bring your body in line with the saw blade.
When kickback occurs, the circular saw may jump
backwards but the operator can control the kick-
back forces by adopting suitable precautions.
b. If the saw blade jams or sawing stops for an-
other reason, release the ON / OFF switch and
hold the saw in the workpiece without mov-
ing it until the saw blade comes to a complete
stand still. Never try to remove the saw from
the tool or to pull it backwards as long as the
saw blade is still moving otherwise this could
cause a recoil action. Find the reason for the
saw blade jamming and take the appropriate ac-
tion to rectify it.
c. If you wish to restart a saw that has been in-
serted into the workpiece, centre the saw
blade in the saw gap and check that the saw
teeth do not catch on the workpiece. If the saw
blade jams, it may move itself out of the workpiece
or cause a kickback when the saw is restarted.

d. Support boards whilst cutting to reduce the
risk of kickback caused by a jammed saw
blade. Large boards may bend under their own
weight. Boards must be supported on both sides
as well as near the saw gap and at the edges.
e. Do not use blunt or damaged saw blades. Saw
blades with blunt or misaligned teeth are in effect
too wide for the designed saw gap and this gives
rise to increased friction, jamming and kickback.
f. Make sure that the cutting depth and angle
setting fastenings are tightened before saw-
ing starts. If these settings move during sawing,
this can lead to the saw blade jamming and kick-
back.
g. Be particularly careful when carrying out
a plunge cut in an obscured area, e.g. in an
existing wall. The plunging blade could jam in a
hidden object and cause kickback.
Causes of kickback:
1. A kickback is a sudden reaction to a saw blade
becoming hooked, jammed or misaligned. This
causes an out of control circular saw to raise itself
and move out of the workpiece and towards the
operator.
2. If the sawblade becomes hooked or trapped in a
narrowing saw gap, it is suddenly prevented from
rotating and the force of the motor throws the de-
vice back in the direction of the operator.
3. If the sawblade distorts or becomes misaligned in
the saw cut, the teeth at the rear edge of the saw-
blade may hook themselves into the workpiece
surface causing the sawblade to move out of the
saw gap and the circular saw to jump backwards
in the direction of the operator.
Special safety advice for circular saws and auto-
matic blade guards
a. Before you use the saw, always check that the
automatic blade guard (7) closes properly. Do
not use the saw if the bottom compartment of
the blade guard does not move freely or close
immediately. Never jam or tie the automatic
blade guard in the open position. The bottom
part of automatic blade guard may become bent if
the saw falls on to the floor. Open the blade guard
with the release lever and make sure that it moves
freely and does not touch the saw blade or other
parts at all cutting angles and depths.
b. Check that the spring on the automatic blade
guard functions properly. If the automatic
blade guard or spring does not function prop-
erly, have the device serviced before you use
it. Damaged parts, sticky deposits or accumula-
tions of splinters can delay the operation of the
bottom blade guard.
c. Open the automatic blade guard by hand only
for certain cuts such as plunge or angle cuts.
