Lower Guard Function - DeWalt DWE574 Manual De Instrucciones

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 saw blade is binding, 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 use abrasive wheels or blades.
WARNING: Do not use water feed attachments.
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 (Refer to Causes and Operator Prevention of
Kickback and KICKBACK).
• Avoid cutting nails. Inspect for and remove all nails from
lumber before cutting.
• 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.
