Additional Safety Instructions For Circular Saws - DeWalt D23620-XE Instruction Manual

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, centre 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 minimise 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 making a "plunge cut" into existing walls or other
blind areas. The protruding blade may cut objects that can cause kickback.
Safety instructions for saws with a pendulum blade guard
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 safety instructions for circular saws

• Wear ear protectors. Exposure to noise can cause hearing loss.
• Preferably wear a dust mask.
• Do not use blades of larger or smaller diameter than recommended. For the
proper blade rating refer to the technical data. Use only the blades specified in
this manual, complying with EN 847-1.
• Never use abrasive cut-off wheels.
Use only the blades specified in this manual,complying with EN 847-1.
• Do not use distorted or cracked saw blades.
• Do not use a blade made of high-speed steel.
• Do not use a blade not in conformity with features as described in this manual.
• Do not exert lateral force to stop the blade.
• Do not set the movable guard in the open position.
• Ensure freely moving guard without binding.
• Ensure proper movement of retracting mechanism of all the protection system.
• Prior to blade replacement, adjustment or othermaintenance, always unplug the
tool.
• Never use any abrasive wheel unless a tool isspecially designed for abrasive
wheels.
• Do not use a blade with thinner blade body than the riving knife and tooth set.
• The riving knife must be adjusted not more than 5 mm from the blade tooth
circle, and the tooth length below the lower edge of the riving knife shall not be
bigger than 5 mm.
• Always use the riving knife except when plunge cutting.
• Never use abrasive cut-off wheels.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known 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.
