DETAILED SAFETY REGULATIONS
DETAILS OF OPERATIONAL SAFETY FOR CIRCULAR SAWS
WITHOUT RIVING KNIFE
CAUTION:
Neglecting the instructions specified in the below warnings
about risks and guidelines for safety of use may cause risks of
electric shock, fire and/or serious injuries.
Cutting procedures
a. DANGER Keep hands away from cutting area and the blade.
Keep your second hand on auxiliary handle, or motor
housing. If both hands are holding the sow, they cannot be cut by
the blade.
b. Do not reach underneath the workpiece. The guard cannot
protect you from the blade below the workpiece.
c. Adjust the cutting depth to the thickness of the workpiece.
Less that 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 the power tool by insulated surfaces gripping surfaces
only, 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 could give the operator an electric shock.
f. When ripping, always use a rip fence or starting 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 bolts. The
blade washers and bolt were specially designed for your saw, for
optimum performance and safety of operation.
Kickback causes and related warnings
• 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
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 back towards the
operator.
Kickback is the result of saw misuse and/or incorrect operating
procedures or conditions and can be 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
52G684
the material. If saw blade is binding, it may walk up or cause
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 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 sawing into existing walls or other
blind areas. The protruding blade may cut objects that can
cause kickback.
Lower guard function
a.
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 retracing handle and make sure it
moves freely and does not touch the blade or any other part, in all
angles and depths of cut.
b.
Check the operation 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 build-up of debris.
c.
Lower guard may be retracted manually only for special cuts
such as "plunge cuts" and "compound cuts". Raise lower guard
by retracting handle and as soon as blade enters the material, the
lower guard must be released. For all other sawing, the lower guard
should operate automatically.
d.
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.
Additional safety instructions
• Do not use damaged or deformed cutting blades.
• Do not use grinding wheels.
• Use only cutting blades that are recommended by the manufacturer
and comply with the standard EN 847-1.
• Do not use cutting blades without sintered carbide tips on teeth.
• Dust of certain wood types may be dangerous to health. Direct
physical contact with dusts may cause allergic reaction and/or
respiratory system diseases of operator or bystanders. Dusts of oak
and beech are considered carcinogenic, especially in connection with
wood processing substances (wood impregnants).
• Use personal protection measures, such as:
– earmuff protectors to reduce risk of hearing damage,
– eye shield,
– respiratory system protection to reduce risk of harmful dusts
inhalation,
– gloves for maintenance of cutting blades and other rough and sharp
materials (hold cutting blades by mount hole whenever possible).
• Connect dust extraction system when cutting wood.
Safe work and maintenance
• Match cutting blade with material that you plan to cut.
• Never use the saw for cutting materials other than wood and wood-
like.
• Do not use the saw without guard or when the guard is blocked.
• Floor close to the machine work place must be kept tidy and without
loose materials and protrusions.
• Provide appropriate work place illumination.
• Machine operator must be properly trained for use, operation and
working with the machine.
• Use only sharp cutting blades.
• Observe maximum speed indicated on the cutting blade.
• Make sure to use parts in accordance with the manufacturer's
instructions.
• Disconnect the saw from power supply when performing
maintenance tasks.
