Lower Guard Function; Additional Safety Information - DeWalt DCS577 Manual De Instrucciones

English
kickback may occur. Investigate and take corrective
actions to eliminate the cause of blade binding.
c ) When restarting a saw in the workpiece, center
the saw blade in the kerf and check that 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.
d ) 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.
e ) Do not use dull or damaged blades. Unsharpened
or improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
f ) 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.
g ) 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

a ) 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.
b ) 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.
c ) 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.
d ) 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.
Additional Specific Safety Instructions for
Circular Saws

WARNING: Do not allow familiarity (gained from
frequent use of your saw) to replace safety rules.
Always remember that a careless fraction of a second
is sufficient to inflict severe injury.

Use clamps or another practical way to secure and
•
support the workpiece to a stable platform. Holding
the work by hand or against your body leaves it unstable
and may lead to loss of control.
Keep your body positioned to either side of the
•
blade, but not in line with the saw blade. KICKBACK
could cause the saw to jump backwards (see Kickback
Causes and Related Warnings and Kickback).
Avoid cutting nails. Inspect for and remove all nails
•
from lumber before cutting.
Always make sure nothing interferes with the
•
movement of the lower blade guard.
Accessories must be rated for at least the speed
•
recommended on the tool warning label. Wheels and
other accessories running over rated speed can fly apart
and cause injury. Accessory ratings must always be above
tool speed as shown on tool nameplate.
• Always make sure the saw is clean before using.
• Stop using this saw and have it properly serviced if any
unusual noise or abnormal operation occcurs.
• Always be sure all components are mounted properly and
securely before using tool.
• Always handle the saw blade with care when mounting or
removing it or when removing the diamond knockout.
• Always wait until the motor has reached full speed before
starting a cut.
• Always keep handles dry, clean and free of oil and grease.
Hold the tool firmly with both hands when in use.
• Always be alert at all times, especially during repetitive,
monotonous operations. Always be sure of position of
your hands relative to the blade.
• Stay clear of end pieces that may fall after cutting off. They
may be hot, sharp and/or heavy. Serious personal injury
may result.

Additional Safety Information


WARNING: Never modify the power tool or any part
of it. Damage or personal injury could result.

WARNING: ALWAYS use safety glasses. Everyday
eyeglasses are NOT safety glasses. Also use face or
dust mask if cutting operation is dusty. ALWAYS WEAR
CERTIFIED SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.

WARNING: Some dust created by power sanding,
sawing, grinding, drilling, and other construction
activities contains chemicals known to the State
of California to cause cancer, birth defects or
other reproductive harm. Some examples of these
chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other
masonry products, and
• arsenic and chromium from chemically-
treated lumber.
