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.
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.
i)
Keep your body positioned to either
side of the blade, but not in line with the
saw blade.
KICKBACK could cause the
saw to jump backwards (see
Causes and
Operator Prevention of Kickback
).
j)
CAUTION:
Blades coast after turn off.
Serious personal injury may result.
k)
Avoid cutting nails. Inspect for and
remove all nails from lumber before
cutting.
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 the
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 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.
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)
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.
b)
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.
c)
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.
d)
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.
e)
Do not use dull or damaged blades.
Unsharpened or improperly set blades
produce narrow kerf causing excessive
friction, blade binding and kickback.
f)
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.
g)
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.
Lower Guard Safety Instructions
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.
