▶
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 guard return 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.

▶
Do not switch the product on before it is at the workplace.
▶
Remove the battery before storing or transporting the power tool.
▶
Do not work overhead with the product.
▶
Do not attempt to brake the product by applying lateral pressure to the saw blade.
▶
The kerf must be free of obstructions. Do not saw into screws and nails etc.
▶
Do not touch the clamping flange or the clamping screw while the power tool is running.
▶
Never press the drive spindle lock button while the saw blade is rotating.
▶
Never direct the power tool toward persons.
▶
Adjust the pressure applied to the saw blade and the material being cut so that the blade does not
stall, possibly causing kickback.
▶
Avoid overheating the tips of the saw blade teeth.
▶
When cutting plastic, melting of the plastic should be avoided.
▶
Dust from materials, such as paint containing lead, some wood species, concrete / masonry / stone
containing silica, and minerals as well as metal, may be harmful. Contact with or inhalation of the dust
