Additional Safety Warnings; Maintenance And Servicing - DeWalt DW872-QS Instructions Manual

Kickback is the result of power tool misuse and/or incorrect
operating procedures orconditions and can be avoided by taking
proper precautions as given below.
Maintain a firm grip on the power tool and position your
•
body and arm to allow you to resist kickback forces.
The operator can control upward kickback forces, if proper
precautions are taken.
Do not position your body in line with the rotating
•
saw blade. If kickback occurs, it will propel the cutting unit
upwards toward the operator.
Do not "jam" the saw blade or apply excessive pressure.
•
Do not attempt to make an excessive depth of cut.
Overstressing the saw blade increases the loading and
susceptibility to twisting or binding of the saw blade in the cut
and the possibility of kickback or saw blade breakage.
When the saw blade is binding or when interrupting a
•
cut for any reason, switch off the power tool and hold
the cutting unit motionless until the saw blade comes to
a complete stop. Never attempt to remove the saw blade
from the cut while the saw blade is in motion otherwise
kickback may occur. Investigate and take corrective action to
eliminate the cause of saw blade binding.
Do not restart the cutting operation in the workpiece.
•
Let the saw blade reach full speed and carefully re‑enter
the cut. The saw blade may bind, walk up or kickback if the
power tool is restarted in the workpiece.
Support any oversized workpiece to minimize the risk of
•
saw blade pinching and kickback. Large workpieces tend
to sag under their own weight. Supports must be placed under
the workpiece near the line of cut and near the edge of the
workpiece on both sides of the saw blade.
Additional Safety for Metal Cutting Chopsaw
• Do not use saw blades manufactured from high speed steel.

WARNING: Do not connect to the mains power supply
into the unit until complete instructions are read
and understood.
DO NOT OPERATE THIS MACHINE until it is completely
•
assembled and installed according to the instructions. A
machine incorrectly assembled can cause serious injury.
OBTAIN ADVICE from your supervisor, instructor, or another
•
qualified person if you are not thoroughly familiar with the
operation of this machine. Knowledge is safety.
MAKE CERTAIN the blade rotates in the correct direction. The
•
teeth on the blade should point in the direction of rotation as
marked on the saw.

Additional Safety Warnings

TIGHTEN ALL CLAMP HANDLES, knobs and levers prior to
•
operation. Loose clamps can cause parts or the workpiece to
be thrown at high speeds.
BE SURE all blade and blade clamps are clean, recessed
•
sides of blade clamps are against blade and arbour screw is
tightened securely. Loose or improper blade clamping may
result in damage to the saw and possible personal injury.
DO NOT OPERATE ON ANYTHING OTHER THAN THE
•
DESIGNATED VOLTAGE for the saw. Overheating, damage
to the tool and personal injury may occur.
DO NOT WEDGE ANYTHING AGAINST THE FAN to hold
•
the motor shaft. Damage to tool and possible personal injury
may occur.
NEVER HAVE ANY PART OF YOUR BODY IN LINE WITH
•
THE PATH OF THE SAW BLADE. Personal injury will occur.
NEVER APPLY BLADE LUBRICANT TO A RUNNING
•
BLADE. Applying lubricant could cause your hand to move
into the blade resulting in serious injury.
DO NOT place either hand in the blade area when the saw is
•
connected to the power source. Inadvertent blade activation
may result in serious injury.
NEVER REACH AROUND OR BEHIND THE SAW BLADE. A
•
blade can cause serious injury.
DO NOT REACH UNDERNEATH THE SAW unless it is
•
unplugged and turned off. Contact with saw blade may cause
personal injury.
SECURE THE MACHINE TO A STABLE SUPPORTING
•
SURFACE. Vibration can possibly cause the machine to slide,
walk, or tip over, causing serious injury.
USE ONLY BLADES OF THE CORRECT SIZE AND TYPE
•
specified for this tool to prevent damage to the machine and/
or serious injury (complying with EN847-1).
INSPECT BLADE FOR CRACKS or other damage prior to
•
operation. A cracked or damaged blade can come apart and
pieces can be thrown at high speeds, causing serious injury.
Replace cracked or damaged blades immediately. Observe the
maximum speed marked on the saw blade.
CLEAN THE BLADE AND BLADE CLAMPS prior to
•
operation. Cleaning the blade and blade clamps allows you to
check for any damage to the blade or blade clamps. A cracked
or damaged blade or blade clamp can come apart and pieces
can be thrown at high speeds, causing serious injury.
THE MAXIMUM SPEED OF THE SAW BLADE shall always
•
be greater than or at least equal to the speed marked on the
rating plate of the tool.
THE SAW BLADE DIAMETER must be in accordance with
•
the markings on rating plate of the tool.
DO NOT USE WARPED BLADES. Check to see if the blade
•
runs true and is free from vibration. A vibrating blade can
cause damage to the machine and/or serious injury.
DO NOT use lubricants or cleaners (particularly spray or
•
aerosol) in the vicinity of the plastic guard. The polycarbonate
material used in the guard is subject to attack by
certain chemicals.
KEEP GUARD IN PLACE and in working order.
•
AVOID UNCONTROLLED RELEASE of the saw head from
•
fully down position. Otherwise there is a risk that the machine
will tip over.
