2. Many thanks for choosing this product!
We're pleased that you decided to purchase your new Wacker Neuson
cut-off saw. The Wacker Neuson cut-off saws are equipped with specially designed high performance engines with an excellent power to
weight ratio for better performance at a lower weight.
Other advantages of the Wacker Neuson cut-off saw include:
∗ Robust construction and high reliability.
∗ Maintenance-free electronic ignition, hermetically encapsulated to pre-
vent dust and moisture from entering.
∗ Vibration damping with a double-mass system that allows operators to
work nearly without fatigue, even with a hand-operated machine.
∗ Five stage air cleaner system for reliable operation, even when an un-
usual amount of dust is produced.
∗ Two ways to mount the cutting blade: Use the center position for opti-
mal balance with the hand-operated machine or the side position for
cutting near to walls or curbs or for horizontal cuts directly above the
ground.
∗ A comprehensive range of accessories, including synthetic resin or di-
amond-encrusted cutting blades and a guide cart, water sprayer and
angular fuel tank filler neck.
We'd like you to be happy with your purchase from Wacker Neuson.
To guarantee that your Wacker Neuson cut-off saw is always ready to
use and functions well and to ensure your personal safety, we'd like to
ask you to:

4. Safety information
4.1 Proper use
Cut-off saw
The cut-off saw must only be used outdoors for cutting/cutting to length
suitable materials with the cutting blade approved for the unit.
Non-approved work methods:
The cutting blades of the cut-off saw must not be used as a grinding
tool (removing material with the side surface of the cutting blade). This
may cause the cutting blade to break! It is prohibited to attach saw
blades, knives or brushes to the cut-off saw.
Non-approved operators:
Persons unfamiliar with the operator's manual, children, juveniles as
well as persons under the influence of alcohol, drugs or medication
must not attempt to operate the unit.
4.2 General notes
4.2.1 To ensure safe handling, the operating person must read the op-
erator's manual (even if that person is experienced in using a cutoff saw), to become familiar with the cut-off saw. Operators can en-
danger themselves and others if they are unaware or insufficiently informed about how to properly use the unit.
4.2.2 Only lend the cut-off saw to experienced users. Give the operator's
manual to the user along with the tool.
4.2.3 First time users should receive instruction from a skilled technician regarding the characteristics of engine-driven cutting.
4.2.4 Children and juveniles under the age of 18 must not attempt to operate
the cut-off saw. Juveniles who are at least 16 years old are excepted
from this rule if they are working under the supervision of qualified personnel for educational purposes.
4.2.5 Working with the cut-off saw requires special precautions.
4.2.6 Work only if you are in good physical condition. Fatigue can lead to
carelessness. Take special precautions, particularly as you finish your
work. Carry out all work calmly and circumspectly. The operator is responsible for others in the area.

Safety information
4.2.7 Never operate the machine under the influence of alcohol, drugs, medication or other substances that can impair your vision, coordination
and judgment.
4.2.8 When working with highly flammable vegetation and in dry conditions
ensure that a fire extinguisher is readily available for use (danger of
fire).
4.2.9 Asbestos or materials that could discharge toxins may only be cut using the proper safety measures and after notifying the responsible authorities and under their supervision or that of persons charged with
this duty. The use of dust bonding devices is strongly recommended.
4.2.10 Some dust created by power sanding sawing, grinding, drilling, and
other construction activities contains chemicals known (to the State of
California) 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
∗ 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.
4.3 Personal protective gear
4.3.1 Wear and use the following protective equipment and devices to prevent head, eye, hand and foot injuries as well as hearing damage.
4.3.2 Clothing should be appropriate, i.e. should be close-fitting but not restrict your movement. When cutting metal, do not wear clothing in
which grains of material can be caught (pants with cuffs, jackets or
pants with open pockets, etc.).
4.3.3 Do not wear jewelry or clothing that can become entangled or distract
the operator from the cutting process.
