Lower Guard Function - DeWalt DC300 Guide D'utilisation

a) Maintain a fi rm grip with both hands on the saw and position
your arms to resist kickback forces. Position your body
to either side of the blade, but not in line with the blade.
Kickback could cause the saw to jump backwards, but kickback
forces can be controlled by the operator, if proper precautions are
taken.
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 a 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 workpiece, center the saw
blade in the kerf and check that the 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.
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. 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 use. Do not
operate 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 and condition 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
buildup 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, 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 fl oor. 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 Specifi c Safety Instructions for
Circular Saws
WARNING: Do not use abrasive wheels or blades.
• Air vents often cover moving parts and should be avoided.
Loose clothes, jewelry or long hair can be caught in moving parts.
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:
