Lower Guard Function - skilsaw SPTH70M Instrucciones De Funcionamiento

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 sawing into
existing walls or other blind areas. The
protruding blade may cut objects that can
cause kickback.
Inspect the condition and quality of the
wood and remove all nails from lumber
before cutting. Wet lumber, green lumber
or pressure treated lumber require special
attention during cutting operation to prevent
kickback.
The blade washers and the bolt on
your saw have been designed to work
as a clutch to reduce the intensity of a
kickback. Understand the operation and
settings of the VARI-TORQUE CLUTCH.
The proper setting of the clutch combined
with firm handling of the saw will allow you to
control kickback.
Kickback
Never place your hand behind the saw
blade. Kickback could cause the saw to jump
backwards over your hand.
Do not use the saw with an excessive
depth of cut setting. Too much blade
exposure increases the likelihood of the blade
twisting in the kerf and increases the surface
area of the blade available for pinching that
leads to kickback.
Vari-torque
Clutch
Hold the saw firmly to prevent loss of
control. Figures in this manual illustrate
typical hand support of the saw.

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.
Periodically remove the blade, clean the
upper, lower guards and the hub area
with kerosene and wipe it dry, or blow
it clean with compressed air. Preventive
maintenance and properly operating guard
will reduce the probability of an accident.
