Residual Risks; Electrical Safety - DeWalt D28730 Instructions Manual

the cut. The wheel may bind, walk up or kickback if the
power tool is restarted in the workpiece.
g ) Support any oversized workpiece to minimize the risk
of wheel 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 wheel.
Additional Safety Instructions for Chopsaws
• Always wear proper eye and respiratory protection and
a leather apron.
• Before using, inspect the cutting wheel for cracks or
flaws. If such a crack or flaw is evident, discard the wheel.
The wheel should also be inspected whenever you think
the tool may have been dropped. Flaws may cause wheel
breakage.
• When starting the tool with a new or replacement wheel
or if you are unsure of the condition of the wheel, hold
the tool in a well protected area and let it run for one
minute. If the wheel has an undetected crack or flaw, it should
burst in less than one minute. Never start the tool with a person
in line with the wheel. This includes the operator.
• In operation, avoid bouncing the wheel or giving it rough
treatment. If this occurs, stop the tool and inspect the wheel
for cracks or flaws.
• Clean your chop saw periodically following the procedure in
this manual.
• Never use the machine without the guards in place.
• Do not remove base.
• Cut-off machines shall be provided with the means to
facilitate the fixing of the machine to a bench to prevent sliding;
e.g. by providing holes or clamping surfaces in the base.
• ALWAYS USE THE VISE OR SPECIAL FIXTURE TO CLAMP
WORK SECURELY. Other aids such as spring, bar, or C-clamps
may be appropriate for certain sizes and shapes of workpiece.
Use care in selecting and placing these clamps and make a dry
run before making a cut.
• Use only 355 mm type 1 wheels rated at 4000 rpm or higher.
• Allow cut off parts to cool before handling.
• Do not attempt to cut wood or plastic with this tool.
• NEVER CUT MAGNESIUM WITH THIS TOOL.
• Use chop saw in a well-ventilated area.
• Turn chop saw off before removing any pieces from the base.
• DO NOT CUT ELECTRICALLY LIVE MATERIAL.
• Do not use circular saw blades or any other toothed
blades with this tool. Serious injury may result.
• DO NOT OPERATE THIS TOOL NEAR FLAMMABLE LIQUIDS,
GASES OR DUST. Sparks or hot chips from cutting or arcing
motor brushes may ignite combustible materials.
• Ensure that the abrasive wheel is correctly fitted and tightened
before use.
• Let the tool run at no-load in a safe position for at least
1 minute. If there is a considerable vibration or if any other
defect occurs, stop the tool and check it to determine the cause.
• Ensure that ventilation slots are kept clear when working in
dusty conditions. First disconnect the machine from the mains
supply then clean the openings by using a soft brush.
• Do not use the side of the abrasive wheel as a deburring
grinder. This will substantially weaken the wheel creating an
unsafe condition. The wheel may come apart.
• The wheel continues to rotate after the machine is switched off.
WARNING: Wear appropriate hearing protection
during use. Under some conditions and duration of use,
noise from this product may contribute to hearing loss.
CAUTION: Spark deflector will get hot. Avoid touching or
adjusting while hot. Keep cordset and materials away from
spark deflector.
• Avoid prolonged contact with dust from cutting activity
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.
• Do not use toothed blades.
• Always store cutting discs well-protected and in a dry place, out
of reach of children.
• Do not expose to rain or use in damp locations.
• Only use chop saw wheel of a max. thickness of
3.0 mm and a max. diameter of 355 mm.

Residual Risks

The following risks are inherent to the use of these machines:
• Injuries caused by touching the rotating parts.
• Injuries caused by disruption of the cutting disc.
These risks are most evident:
• Within the range of operation.
• Within the range of the rotating machine 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
cutting disc.
• Risk of injury when changing the disc.
• Risk of squeezing fingers when opening the guards.

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 WALT tool is double insulated in accordance
E
with EN62841; therefore no earth wire is required.
If the supply cord is damaged, it must be replaced by a specially
prepared cord available through the D
Mains Plug Replacement
(Middle East and Africa)
If a new mains plug needs to be fitted:
• Safely dispose of the old plug.
