• 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 towards operator
KICKBACK - OPERATOR PREVENTION
Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided
by taking proper precautions as given below
• Maintain a fi rm 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 backwards while the blade is in motion or kickback may occur
(investigate and take corrective actions to eliminate the cause of blade binding; avoid cutting nails or
screws)
• 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)
• 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 a dull or damaged blade (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)
WARNING
• 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
• 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)
• Lower guard should 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)
• 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)
• Avoid damage that can be caused by screws, nails and other elements in your workpiece; remove them
before you start cutting
• When you put away the tool, switch off the motor and ensure that all moving parts have come to a complete
standstill
• Use completely unrolled and safe extension cords with a capacity of 16Amps (U.K. 13Amps)
• In case of jamming or electrical or mechanical malfunction, immediately switch off the tool and disconnect
the plug
• The WORLDPRO can assure fl awless functioning of the tool only when original accessories are used
• Use only accessories with an allowable speed matching at least the highest no-load speed of the tool
• Never use the tool without the original protection guard system
• This tool should not be used by people under the age of 16 years
• The noise level when working can exceed 85 dB(A);wear ear protection
• If the cord is damaged or cut through while working, do not touch the cord, but immediately disconnect the
plug
• Never use tool when cord is damaged; have it replaced by a qualified person
• Always check that the supply voltage is the same as the voltage indicated on the nameplate of the tool (tools
