Keep cutting tools sharp and clean. Properly main-
u
tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
Use the power tool, accessories and tool bits etc. in
u
accordance with these instructions, taking into ac-
count the working conditions and the work to be per-
formed. Use of the power tool for operations different
from those intended could result in a hazardous situation.
Keep handles and grasping surfaces dry, clean and
u
free from oil and grease. Slippery handles and grasping
surfaces do not allow for safe handling and control of the
tool in unexpected situations.
Service
Have your power tool serviced by a qualified repair
u
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
Special Safety Instructions for AAC Block Cutter
Keep all parts of the body away from the saw chain
u
when the saw is running. Before starting up the saw,
ensure that the saw chain is not touching anything.
When working with a power tool, a moment of inattention
could lead to clothing or parts of the body being caught by
the saw chain.
Always hold the power tool with your right hand on
u
the rear grip and your left hand on the front grip. Hold-
ing the power tool with the reversed hand configuration
increases the risk of injuries and must not be used.
Only hold the power tool by the insulated gripping sur-
u
faces because the saw chain may come into contact
with hidden electrical cables or its own power cable. If
the saw chain comes into contact with a live wire, this
may make metal parts of the tool live as well, posing a risk
of electric shock.
Wear protective eyewear and a dust mask. Additional
u
protective equipment for ears, head, hands, legs and
feet is recommended. Appropriate protective clothing
reduces the risk of injury from flying chip material and
anything accidentally coming into contact with the saw
chain.
Do not work with the power tool on a ladder, from a
u
roof or on an unstable support. Operating a power tool
in this way may lead to serious injuries.
Always ensure that you have a secure footing and only
u
use the power tool if you are standing on solid, secure
and level ground. Slippery or unstable surfaces can
cause you to lose your balance or lose control over the
power tool.
With the power tool switched off, carry it by the front
u
grip with the saw chain facing forwards. Always put on
the protective cover when transporting or storing the
power tool. Handling the power tool carefully reduces
the likelihood of the running saw chain accidentally com-
ing into contact with an object.
Follow the instructions for the chain tension and for
u
changing the saw blade body and the chain. A chain
1 609 92A 8GA | (21.03.2023)
that is not tensioned correctly may break or may increase
the risk of kickback.
Only saw autoclaved aerated concrete. The power tool
u
must not be used for work that it is not intended for.
Example: Do not use the power tool to saw metal,
plastic, masonry, soil, ice or wood. Using the power tool
for work that is not intended for may lead to dangerous
situations.
If you are removing accumulated material, storing the
u
power tool or performing maintenance, follow all of
the instructions. Ensure that the on/off switch is
switched off and the mains plug is not plugged in. Un-
intentionally activating the power tool when removing ac-
cumulated material or during maintenance may lead to
serious injuries.
Causes of kickbacks and prevention:
u
– Kickbacks may occur if the tip of the guide rail comes
into contact with an object.
– If an object comes into contact with the tip of the guide
rail, it may cause the power tool to react unexpectedly in
a backwards direction, during which the guide rail is
knocked upwards and in the direction of the operator.
– If the saw chain jams on the top edge of the guide rail,
the rail may quickly kick back in the direction of the oper-
ator.
– Any of these reactions may lead to you losing control of
the power tool or seriously injuring yourself. Do not solely
rely on the safety devices built into the power tool. As the
user of a power tool, you should take a number of meas-
ures so that you can work without accidents or injuries.
Kickback is the result of misuse or incorrect use of the
power tool. It can be avoided by taking proper precau-
tions as given below.
Hold the power tool firmly with both hands, with the
u
handles of the power tool grasped with your thumb
and finger. Move your body and arms into a position
from which you can withstand the kickback forces. If
suitable measures are taken, the operator can control the
kickback forces. Never let go of the power tool.
Avoid adopting an abnormal posture and do not saw
u
above shoulder height. This prevents the tip of the guide
rail accidentally coming into contact with an object and
gives you better control of the power tool if unexpected
situations occur.
Always use replacement rails, saw chains and
u
sprocket wheels specified by the manufacturer. Using
incorrect replacement rails, saw chains and sprocket
wheels may cause the chain to break or lead to kickbacks.
Always follow the manufacturer's instructions for
u
maintaining the saw chain. Setting depth gauges too
low increases the likelihood of kickbacks.
