the workpiece.
Less than a full tooth of the
blade teeth should be visible below the
workpiece.
d.
Never hold piece being cut in your hands or
across your leg. Secure the workpiece to a
stable platform.
It is important to support the
work properly to minimize body exposure, blade
binding, or loss of control.
e.
Hold power 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 will also make exposed metal parts of the
power tool “live” and shock the operator.
f.
When ripping always use a rip fence or
straight edge guide.
This improves the
accuracy of cut and reduces the chance of
blade binding.
g.
Always use blades with correct size and
shape (diamond versus round) of arbour
holes.
Blades that do not match the mounting
hardware of the saw will run eccentrically,
causing loss of control.
h.
Never use damaged or incorrect blade
washers or bolt.
The blade washers and bolt
were specially designed for your saw, for
optimum performance and safety of operation.
FURTHER SAFETY INSTRUCTIONS FOR ALL
SAWS
Causes and operator prevention of kickback:
a.
Kickback is a sudden reaction to a pinched,
bound or misaligned saw blade, causing an
uncontrolled saw to lift up and out of the
workpiece toward the operator.
b.
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.
c.
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 back toward the operator.
d.
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.
e.
Maintain a firm grip with both hands on the
saw and position your arms to resist
kickback forces.
Position your body to either
side of the blade, but not in line with the blade.
Kickback could cause the saw to jump
backwards, but kickback forces can be
controlled by the operator, if proper precautions
are taken.
NOTE
For circular saws with 165 mm or smaller
diameter blades, the words “with both hands” may
be omitted.
f.
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,
centre 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.
h.
Support large panels to minimise the risk of
blade pinching and KICKBACK.
Large panels
tend to sag 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.
i.
Do not use dull or damaged blades
Unsharpened or improperly set blades
produce narrow kerf causing excessive
friction, blade binding and kickback.
g.
Blade depth and bevel adjusting locking
levers must be tight and secure before
making cut.
If blade adjustment shifts while
cutting, it may cause binding and kickback.
k.
Use extra caution when making a “plunge
cut” into existing walls or other blind areas.
The protruding blade may cut objects that
can cause kickback.
SAFETY INSTRUCTIONS FOR CIRCULAR SAW
LOWER GUARD FUNCTION
a.
Check lower guard for proper closing before
each use.
Do not operate the 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.
