should be at least 0.6 liters (20 fl.oz) of
water per minute. If wet cutting at the
recommended flow rate is not utilized,
the operator and any bystanders should
always wear a respirator approved by
NIOSH/MSHA for the material being cut.
See also the section on "Respiratory
Protection" in the chapter "Sample
Applications" in the instruction manual.
Even if wet cutting at the recommended
flow rate, an operator who is actively
cutting for more than two hours in one
day should wear at least a NIOSH-
approved disposable respirator. Consult
and follow any federal, state or local
laws or regulations with respect to dry
and wet cutting.
WARNING
Cutting masonry, concrete and other
materials with silica in their composition
may give off dust containing crystalline
silica. Silica is a basic component of
sand, quartz, brick clay, granite and
numerous other minerals and rocks.
Repeated and/or substantial inhalation
of airborne crystalline silica can cause
serious or fatal respiratory diseases,
including silicosis. In addition, California
and some other authorities have listed
respirable crystalline silica as a
substance known to cause cancer.
When cutting such materials, always
follow the respiratory precautions
mentioned above.
WARNING
Breathing asbestos dust is dangerous
and can cause severe or fatal injury,
respiratory illness or cancer. The use
and disposal of asbestos-containing
products have been strictly regulated by
10
OSHA and the Environmental Protection
Agency. Do not use your cut-off machine
to cut or disturb asbestos, asbestos-
containing products, or products such as
pipes which are wrapped or covered
with asbestos insulation. If you have any
reason to believe that you might be
cutting asbestos, immediately contact
your employer or a local OSHA
representative.
A depth limiter with dust extraction
adaptert is available as a special
accessory for the STIHL TSA 230. It is
useful for making steady, price and
depth-limited cuts. When dry cutting, a
dust extractor (vacuum) can be attached
for limited dust suppression purposes.
Such an extractor will only be able to
reduce the amount of dust when the
TSA is operated using certain specific
methods, e.g., when pulling the machine
towards the operator and when making
plunge cuts (for more details see the
Safety Precautions and Use Instructions
that accompany this accessory). It will
not, however, eliminate such dust, or the
need to wear appropriate respiratory
protection. An international standard
(IEC 60335-2-69:2012 states in
§ 22.AA.201) recommends that a dust
extractor used for picking up mineral
dust such as silica (from cutting
concrete, masonry and stone) should be
at least a Class M machine (i.e., Class M
or the higher Class H).

WARNING
To reduce the risk of personal injury
from unintentional starting when
grasping the rear handle or carrying your
cut-off machine, wrap the fingers of your
right hand tightly around the rear handle,
identified by shading in the illustration
above (1). Avoid grasping your cut-off
machine outside the shaded area or
contacting the trigger switch lockout or
trigger switch.
WARNING
Your STIHL cut-off machine is designed
for hand-held use. Cutting with your cut-
off machine resting on the ground or
other surface can cause excessive wear
to the guide plate designed to protect the
bottom of the front handle. Replace a
damaged or badly worn guide plate
immediately.
