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.
• 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.
• 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 occur.
• Investigate and take corrective actions to eliminate the cause of blade binding.
• When restarting a saw in the workpiece, center the saw blade in the kerf and check
that saw teeth are not engaged into the material.
• If the blade is binding, it may walk up or kickback from the workpiece as the saw is
restarted.
• Support large panels to minimize 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.
• Do not use dull or damaged blades.
• Unsharpened or improperly set blades produce narrow kerf causing excessive
friction, blade binding and kickback.
• 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.
• 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 precautions on using circular saw
1. Never use damaged saw blades.
2. Never use saw blades made from high speed steel.
3. Never use cutting wheels with properties which do not comply with the
specifications indicated in this manual.
4. Never stop saw blades by pressing on the side.
5. Always keep saw blades sharpened.
6. Ensure that the lower guard smoothly performs to cover the saw blade.
7. Never operate the saw if lower guard is tied into the open position.
8. Ensure that dust extraction device function correctly.
9. Never operate the saw if saw blade is turned upwards or sideways.
10. Ensure the material has no alien objects e.g. nails.
