Electrical Safety
The electric motor has been designed for one voltage only. Always check that the power
supply corresponds to the voltage on the rating plate.
Your D
e
WALT tool is double insulated in accordance
with EN62841; therefore no earth wire is required.
If the supply cord is damaged, it must be replaced only by D
e
WALT or an authorised
service organisation.
Mains Plug Replacement
(U.K. & Ireland Only)
If a new mains plug needs to be fitted:
• Safely dispose of the old plug.
• Connect the brown lead to the live terminal in the plug.
• Connect the blue lead to the neutral terminal.
WARNING:
No connection is to be made to the earth terminal.
Follow the fitting instructions supplied with good quality plugs. Recommended fuse: 13 A.
Using an Extension Cable
If an extension cable is required, use an approved 3–core extension cable suitable for the
power input of this tool (see
Technical Data ).The minimum conductor size is 1.5 mm
2
; the
maximum length is 30 m.
When using a cable reel, always unwind the cable completely.
Residual Risks
The following risks are inherent to the use of saws:
• Injuries caused by touching the rotating parts.
In spite of the application of the relevant safety regulations and the implementation of safety
devices, certain residual risks cannot be avoided. These are:
•
Impairment of hearing.
• Risk of accidents caused by the uncovered parts of the rotating saw blade.
• Risk of injury when changing the blade.
• Risk of squeezing fingers when opening the guards.
• Health hazards caused by breathing dust developed when sawing wood, especially oak,
beech and MDF.
The following factors increase the risk of breathing problems:
• No dust extractor connected when sawing wood.
• Insufficient dust extraction caused by uncleaned exhaust filters.
m ) Do not use another person as a substitute for a table extension or as additional
support.
Unstable support for the workpiece can cause the blade to bind or the workpiece
to shift during the cutting operation pulling you and the helper into the spinning blade.
n ) The cut-off piece must not be jammed or pressed by any means against the
spinning saw blade.
If confined, i.e. using length stops, the cut-off piece could get
wedged against the blade and thrown violently.
o ) Always use a clamp or a fixture designed to properly support round material such
as rods or tubing.
Rods have a tendency to roll while being cut, causing the blade to
“bite” and pull the work with your hand into the blade.
p ) Let the blade reach full speed before contacting the workpiece. This will reduce the
risk of the workpiece being thrown.
q ) If the workpiece or blade becomes jammed, turn the mitre saw off. Wait for
all moving parts to stop and disconnect the plug from the power source and/
or remove the battery pack. Then work to free the jammed material.
Continued
sawing with a jammed workpiece could cause loss of control or damage to the mitre saw.
r ) After finishing the cut, release the switch, hold the saw head down and wait for
the blade to stop before removing the cut-off piece.
Reaching with your hand near
the coasting blade is dangerous.
s ) Hold the handle firmly when making an incomplete cut or when releasing the
switch before the saw head is completely in the down position.
The braking action
of the saw may cause the saw head to be suddenly pulled downward, causing a risk
of injury.
Additional Safety Rules for Mitre Saws
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.
• 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 CUT METALS
or masonry. Either of these can cause the carbide tips to fly off the blade
at high speeds causing serious injury.
• 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 CROSSCUT SAW BLADES
recommended for mitre saws. For best results, do not
use carbide tipped blades with hook angles in excess of 7 degrees. Do not use blades with deep
gullets. These can deflect and contact the guard, and can cause damage to the machine and/
or 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.
• 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.
• ALWAYS USE THE KERF PLATE AND REPLACE THIS PLATE WHEN DAMAGED. Small chip
accumulation under the saw may interfere with the saw blade or may cause instability of
workpiece when cutting.
• USE ONLY BLADE CLAMPS SPECIFIED FOR THIS TOOL to prevent damage to the machine
and/or serious injury.
• MAKE SURE to use the correct saw blade for the material to be cut.
• CLEAN THE MOTOR AIR SLOTS of chips and sawdust. Clogged motor air slots can cause the
machine to overheat, damaging the machine and possibly causing a short which could cause
serious injury.
• NEVER LOCK THE SWITCH IN THE “ON” POSITION. Severe personal injury may result.
• NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or if the cutting tool
is unintentionally contacted.
WARNING: Cutting plastics, sap coated wood, and other materials may cause melted
material to accumulate on the blade tips and the body of the saw blade, increasing the
risk of blade overheating and binding while cutting.
WARNING: Always wear proper personal hearing protection. Under some
conditions and duration of use, noise from this product may contribute to hearing loss. Be
aware of the following factors influencing exposure to noise:
• Use saw blades designed to reduce the emitted noise,
• Use only well sharpened saw blades, and
• Use specifically designed noise-reduction saw blades.
WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses. Also
use face or dust mask if cutting operation is dusty.
WARNING: Use of this tool can generate and/or disperse dust, which may cause serious
and permanent respiratory or other injury.
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.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well ventilated area, and work with approved safety
equipment, such as those dust masks that are specially designed to filter out microscopic particles.
•
Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling,
and other construction activities.
Wear protective clothing and wash exposed areas with
soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote
absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disperse dust, which may cause serious
and permanent respiratory or other injury. Always use approved respiratory protection
appropriate for the dust exposure.
