damaged or use other, undamaged tool. Once the working tool has been checked and installed,
start the power tool and allow it to work for one minute at maximum speed. Make sure that user
and bystanders stay away from range of the rotating working tool. Damaged tools usually break
during this test.
Wear personal protection equipment. Depending on the task, use protective mask that shields
whole face, eye protection or safety glasses. When necessary use anti-dust mask, hearing
protectors, work gloves or special apron that protects against small particles of grinding and
grinded material. Protect eyes against particles produced at work and floating in the air. Anti-dust mask
and respiratory protection must filter dust produced at work. Prolonged exposure to noise may lead to
hearing loss.
Make sure to keep bystanders at safe distance from the power tool range. Each person close to
operating power tool must use personal protection equipment. Splinters of processed piece or
cracked working tool can chip off and cause damage also beyond direct range.
Whenever power tool can hit hidden electric wires or its own power cord during operation, hold
it only by insulated handle. At contact with live wires all metal parts of the power tool are live too and
may cause electric shock of the operator.
Keep power cord away from rotating working tools. Loss of control over the power tool can lead to
cutting or catching the power cord, also hand or whole arm can get into rotating work tool.
Never put away the power tool before working tool comes to complete stop. Rotating tool can
contact the surface it is put on, which can cause loss of control over the power tool.
Do not carry power tool when it is rotating. Accidental contact of rotating working tool with clothes
may cause its catching and plunging of working tool into operator's body.
Clean ventilation holes of the power tool on regular basis. Motor blower sucks dust into casing and
large depositions of metal dust may cause electric hazards.
Do not use power tool in proximity of flammable materials. Sparks can cause ignition.
Do not use tools that require liquid coolant. Use of water or other liquid coolants may cause electric
shock.
Kick back, causes and ways to reduce it
Kick back is a sudden lift and moving the saw back in the cutting line towards operator. This is caused by
cutting blade being pinched or incorrectly guided.
When cutting blade is caught or pinched in material, the blade stops and motor reaction produces
sudden movement of the saw to the back, towards operator.
If the cutting blade is warped 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 blade and the
saw, and kick back towards operator.
Kick back is 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 allows to resist kick-back. Stand to
the side of the circular saw but 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 or disc jams or stops cutting due to any 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 procedures to eliminate causes
of cutting blade seizing.
When restarting the saw in the processed material, centre 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 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.
