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.
DANGER
Keep your hands away from cutting area and cutting blade.
a.
Keep the second hand on the secondary handle or the motor
casing. When holding the saw with both hands the risk of injury with
cutting blade is reduced.
Do not reach under the processed material. Guard does not
b.
protect from rotating cutting blade below processed material.
Adjust cutting depth to thickness of processed material. It is
c.
recommended that the cutting blade reaches below the processed
material no more than tooth-length.
Never hold processed material in hands, never keep it on legs.
d.
Fix processed material to sound base. Good fixing of processed
material is important to avoid danger of contact with body, rotating
cutting blade being caught or loss of control over the operation.
When operating, hold the saw by insulated surfaces designed
e.
for such purpose.
Be very careful to avoid contact of the rotating blade with live
f.
wires or the power supply cord. Contact of power tool metal parts
with live wire may cause operator's electric shock.
For ripping cuts, always use guide for ripping or edge guide. It
g.
improves cutting accuracy and reduces risk of pinching the rotating
cutting blade in material.
Use only cutting blades with correct arbour hole diameter.
h.
Cutting blades that do not match seating may operate with eccentric
offset, which causes loss of control over operation.
Never use damaged or incorrect washers or bolts to install
i.
cutting blade. Washers and fixing bolts for cutting blade installation
were designed especially for circular saw to provide optimal
operation and safety of use.
Kick back, causes and ways to reduce it
• Kick back is a sudden lift and moving the saw back along the
cutting line towards the operator. This is caused by uncontrolled
cutting with cutting blade being caught, pinched or incorrectly
guided.
• When saw blade is caught or pinched in material, the blade stops
and motor reaction produces sudden movement of the saw to the
back, towards the operator.
• If the saw is unaligned or positioned incorrectly in the object
being cut, blade teeth may hit the upper surface of the material
when leaving the material. It will cause sudden raise of the saw,
and kick back towards the operator.
Kick back is an effect of improper use of circular saw, or wrong
operating procedures or conditions, and can be avoided by
observing applicable, below-mentioned precautions.
Hold the circular saw firmly with both hands in position that
a.
allows to resist kick-back. Stand to the side of the circular saw,
and not in the line of cutting. Kick back may cause sudden move of
circular saw to the back, but its force can be controlled by operator
when appropriate precaution measures are taken.
When the cutting blade jams or stops cutting due to any
b.
reason, release the switch button and hold the saw still in the
material until the blade or disc stops completely. Never attempt
removing the cutting blade from material being cut nor pull the
saw back when the blade is rotating. It may cause kick back.
Investigate and implement correction actions to eliminate causes of
cutting blade seizing.
When restarting the saw in the processed material, centre
c.
the cutting blade in the kerf and ensure the blade teeth are
not blocked in the material. When the cutting blade jams during
restart, it may slide off or cause kick back against the processed
material.
Support large boards to minimize risk of pinching and kick back
d.
of the circular saw. Large boards tend to bend under own weight.
Place supports under board on both sides, close to the cutting line
and close to the board edge.
Do not use blunt or damaged cutting blades. Blunt or incorrectly
e.
positioned blade teeth create narrow kerf, excessive friction, jamming
of cutting blade and kick back.
Firmly set clamps for cutting depth and bevel angle before
f.
making a cut. Change of saw settings when making a cut may cause
jamming and kick back.
Be very careful during plunge cutting in division walls. Cutting
g.
blade may encounter objects not visible from the outside and cause
kick back.
Features of the lower protective guard.
Make sure the lower guard is appropriately positioned before
a.
each use. Do not use the saw when the lower guard does not
move freely and does not close immediately. Do not fix and
do not leave the lower guard open. When the saw is accidentally
dropped the lower guard may get deformed. Lift the lower guard
with pull-handle and ensure it is free to move and does not touch the
blade nor any other part of the tool for any setting of cutting depth
and angle.
Check functioning of the lower guard spring. Repair the guard
b.
and its spring before use when they do not work properly. Lower
guard functioning may be slowed down due to damaged parts, sticky
sediments or building up of layers of wastes.
Manual pulling off the lower guard is allowed only when special
c.
cutting is performed, such as "plunge cutting" and "compound
cutting". Lift the lower guard with its pull handle. As soon as the
cutting blade sinks in the material the guard must be released.
For all other cuts it is recommended that the lower guard works
automatically.
Always make sure the lower guard covers cutting blade before
d.
putting the circular saw away on the workbench or floor.
Uncovered, rotating blade will move the circular saw back and will
cut everything
Additional safety instructions
Precautions
• 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.
