b) 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 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.
c) When restarting a saw in the work piece, centre the saw blade in the kerf and check that
teeth are not engaged into the material. If saw blade is binding, it may walk up or
kickback from the work piece as the saw is restarted.
d) Support large panels to minimize the risk of blade pinching and kickback. Large panels
tend to sag under their own weight. Support must be placed under the panel on both
sides, near the line of cut and near the edge of the panel.
e) Do not use dull or damaged blade. Dull blades produce a narrow kerf causing excessive
friction, blade binding, and kickback.
f) Blade depth and bevel adjusting locking levers must be tight and secure before making a
cut. If depth adjustment shifts while cutting, it may cause binding and kickback.
g) Be particularly careful when making a „plunging cut“ into a hidden area, such as an
existing wall. The saw blade plunging in may get caught in hidden objects while sawing
and lead to kickback.
ADDITIONAL SAFETY INSTRUCTIONS
a) Check before every use that the lower protective guard closes smoothly. Do not use the
saw, if the lower protective guard does not move freely and does not close immediately.
Never block or tie off the lower protective guard in the open position. Should the saw fall
accidentally, the lower protective guard may be bent. Open the protective guard with the
lever and ensure that it moves freely and does not come into contact with either the saw
blade or any other parts at any sawing angle or depth.
b) Check the function of the springs for the lower protective guard. Have the machine
serviced before use, if the lower protective guard and springs do not operate smoothly.
Damaged parts, sticky deposits or accumulations of swarf will retard the operation of the
lower protective guard.
c) Open the lower protective guard by hand only for particular cuts, such as „plunging and
angular cuts“. Open the lower protective guard with the lever and release it as soon as
the saw blade has penetrated the work piece. With all other sawing work, the lower
protective guard must work automatically.
d) Do not place the saw on the work bench or on the floor without checking that the lower
protective guard covers the saw blade. An unprotected saw blade still running will move
the saw towards the direction of sawing and saw anything standing in its path. Be aware
of the time taken for the saw to run down.
