Safety instructions
NOTE
The safety rules in section 1 contain all general
safety rules for power tools which, in accordance
with the applicable standards, require to be listed
in the operating instructions. Accordingly, some
of the rules listed may not be relevant to this tool.
1. General Power Tool Safety Warnings
a) WARNING! Read all safety warnings
and all instructions. Failure to follow the warn-
ings and instructions may result in electric shock,
fire and/or serious injury. Save all warnings
and instructions for future reference. The
term "power tool" in the warnings refers to your
mains-operated (corded) power tool or battery-
operated (cordless) power tool.

1.1 Work area safety

a) Keep work area clean and well lit. Cluttered
or dark areas invite accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power
tools create sparks which may ignite the dust
or fumes.
c) Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
1.2 Electrical safety
a) Power tool plugs must match the outlet.
Never modify the plug in any way. Do not
use any adapter plugs with earthed (ground-
ed) power tools. Unmodified plugs and match-
ing outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or ground-
ed surfaces, such as pipes, radiators, ranges
DC-SE 20 Slitting machine
and refrigerators. There is an increased risk
of electric shock if your body is earthed or
grounded.
c) Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord
for carrying, pulling or unplugging the pow-
er tool. Keep cord away from heat, oil, sharp
edges or moving parts. Damaged or entan-
gled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use
an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces
the risk of electric shock.
f) If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD
reduces the risk of electric shock.

1.3 Personal safety

a) Stay alert, watch what you are doing and
use common sense when operating a pow-
er tool. Do not use a power tool while you
are tired or under the influence of drugs,
alcohol or medication. A moment of inatten-
tion while operating power tools may result in
serious personal injury.
b) Use personal protective equipment. Always
wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the
switch is in the off-position before con-
necting to power source and/or battery pack,
picking up or carrying the tool. Carrying pow-
er tools with your finger on the switch or ener-
gising power tools that have the switch on invites
accidents.
d) Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key
left attached to a rotating part of the power tool
may result in personal injury.
e) Do not overreach. Keep proper footing and
balance at all times. This enables better con-
trol of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing
or jewellery. Keep your hair, clothing and
gloves away from moving parts. Loose clothes,
jewellery or long hair can be caught in moving
parts.
g) If devices are provided for the connection
of dust extraction and collection facilities,
ensure these are connected and properly
used. Use of dust collection can reduce dust-
related hazards.
1.4 Power tool use and care
a) Do not force the power tool. Use the cor-
rect power tool for your application. The cor-
rect power tool will do the job better and safer
at the rate for which it was designed.
b) Do not use the power tool if the switch does
not turn it on and off. Any power tool that can-
not be controlled with the switch is dangerous
and must be repaired.
c) Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
d) Store idle power tools out of the reach of
children and do not allow persons unfa-
miliar with the power tool or these instruc-
tions to operate the power tool. Power tools
are dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalign-
ment or binding of moving parts, breakage
