▶ Maintain a firm grip 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 may
occur. Investigate and take corrective actions to eliminate the cause of blade binding.
▶ When restarting a saw in the workpiece, centre the saw blade in the kerf so that the saw teeth are
not engaged into the material. If a saw blade binds, it may walk up or kickback from the workpiece as
the saw is restarted.
▶ 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.
▶ 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 the cut. If
blade adjustment shifts while cutting, it may cause binding and kickback.
▶ 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
▶ Check the lower guard for proper closing before each use. Do not operate the saw if the lower
guard does not move freely and close instantly. Never clamp or tie the lower guard into the open
position. If the saw is accidentally dropped, the 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.
▶ The lower guard may be retracted manually only for special cuts such as "plunge cuts" and
"compound cuts". Raise the lower guard by the retracting handle and as soon as the 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 the 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
Personal safety
▶ Never tamper with or modify the product or accessories in any way.
▶ Operate the power tool only together with the safety devices that belong to it.
▶ Check that the clamping flange is securely and correctly installed each time before putting the product
into operation.
▶ If you use the power tool without a dust extractor, always wear light respiratory protection when
undertaking work that creates dust.
▶ Wear ear protectors. Exposure to noise can cause hearing loss.
▶ Take breaks between working and do physical exercises to improve the blood circulation in your fingers.
Exposure to vibration during long periods of work can lead to disorders of the blood vessels and nervous
system in the fingers, hands and wrists.
▶ The power tool is not intended for use by debilitated persons who have received no special training.
▶ Do not switch the power tool on until it is at the workplace and has been brought to its working position.
▶ Remove the battery if a problem occurs with the power tool, whenever you change accessory tools or
accessories and before storing or transporting the power tool.
▶ Do not attempt to brake the power tool by applying lateral pressure to the saw blade.
▶ Before inserting the battery, check that the saw is switched off and that the switch-on interlock is
activated. In this way you avoid injuries due to unintentional starting of the power tool.
▶ While the power tool is running, do not touch the clamping flange or the clamping screw.
▶ Before you lay down the power tool, wait until the power tool has come to a complete stop.
▶ Before changing the accessory tool, wait until the power tool has cooled down.
▶ Never press the drive spindle lock button while the saw blade is rotating.
