Starting
WARNING
Your cut-off machine is a one-person
tool. Do not allow other persons in the
general work area, even when starting.
For specific starting instructions, see the
appropriate section of your instruction
manual.
Maintain good balance and secure
footing. Be absolutely sure that the
cutting wheel is clear of you and all other
obstructions and objects, including the
ground. Never attempt to start the cut-off
machine when the abrasive wheel is in a
cut.
Working Conditions
Operate the cut-off machine under good
visibility and daylight conditions only.

Wearing of hearing protection reduces
sound perception. Be alert not to miss
voice signals from co-workers. Keep
within calling distance to other persons
who may assist in case of emergency.
WARNING
Use of this product to cut
masonry, concrete, metal
and other materials can
generate dust and fumes
containing chemicals
known to cause serious
or fatal injury or illness,
such as respiratory dis-
ease, cancer, birth
defects or other repro-
ductive harm. If you are
unfamiliar with the risks
associated with the par-
ticular material being cut,
review the material safety
data sheet and/or con-
sult your employer, the
material manufac-
turer/supplier,
governmental agencies
such as OSHA and
NIOSH and other
sources on hazardous
materials. California and
some other authorities,
for instance, have pub-
lished lists of substances
known to cause cancer,
reproductive toxicity, etc.
Control dust and fumes at
the source where
possible.
In this regard use good work practices
and follow the recommendations of the
manufacturer/supplier, OSHA/NIOSH,
and occupational and trade
associations. A water attachment kit is
provided with your cut-off machine and
should be used to reduce dust whenever
wet cutting is feasible. For dust
suppression purposes, the flow rate
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.
