General Power Tool Safety Warnings
WARNING
Read all safety warnings and
all instructions.
Failure to follow the warnings 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 mainsoperated (corded) power tool or battery-operated
(cordless) power tool.
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.
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
(grounded) power tools.
Unmodified plugs
and matching outlets will reduce risk of electric shock.
b)
Avoid body contact with earthed or
grounded surfaces, such as pipes, radiators, ranges 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
power tool. Keep cord away from heat, oil,
sharp edges or moving parts.
Damaged or
entangled cords increase the risk of electric
shock.
e)
When operating a power tool outdoors, use
an extension cord suitable for outdoor use.
Operating Instructions
Dear Customer,
Thank you for the trust you have placed in us by buying a Metabo power tool. Each Metabo power tool
is carefully tested and subject to strict quality controls by Metabo's quality assurance. Nevertheless, the
service life of a power tool depends to a great extent on you. Please observe the information contained
in these instructions and the enclosed documentation. The more carefully you treat your Metabo power
tool, the longer it will provide dependable service.
Contents
1 Specified Use
2 General Safety Rules

ENGLISH
ENG
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.
3) Personal safety
a)
Stay alert, watch what you are doing and
use common sense when operating a
power tool. Do not use a power tool while
you are tired or under the influence of
drugs, alcohol or medication.
A moment of
inattention 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
connecting to power source and/or battery
pack, picking up or carrying the tool.
Carrying power tools with your finger on the
switch or energising 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
control 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.
4) Power tool use and care
a)
Do not force the power tool. Use the
correct power tool for your application. The
correct 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 cannot 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 mea ures 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
unfamiliar with the power tool or these
instructions to operate the power tool.
Power tools are dangerous in the hands of
untrained users.
e)
Maintain power tools. Check for misalignment or binding of moving parts, breakage
of parts and any other condition that may
affect the power tool's operation. If
damaged, have the power tool repaired
before use.
Many accidents are caused by
poorly maintained power tools.
f)
Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are
easier to control.
g)
Use the power tool, accessories and tool
bits etc. in accordance with these instructions, taking into account the working
conditions and the work to be performed.
Use of the power tool for operations different
from those intended could result in a
hazardous situation.
5) Service
a)
Have your power tool serviced by a
qualified repair person using only identical
replacement parts.
This will ensure that the
safety of the power tool is maintained.
Wear ear protectors.
Exposure to noise can
cause hearingloss.
Use auxiliary handles supplied with the tool.
Loss of control can cause personal injury.
Hold power tools by insulated gripping
surfaces, when performing an operation where
the cutting tool may contact hidden wiring or its
own cord.
Cutting accessory contacting a "live"
wire may make exposed metal parts of the power
tool "live" and could give the operator an electric
shock.
Ensure that the spot where you wish to work is free
of
power cables, gas lines or water pipes
(e.g.
using a metal detector).
WARNING Read all safety warnings and
instructions.
Failure to follow all safety warnings and instructions may result in electric shock,
fire and/or serious injury.
Keep all safety instructions and information for
future reference.
