manufacturer/supplier, governmental
agencies such as OSHA and NIOSH
and other sources on hazardous
materials. California and some other
authorities, for instance, have published
lists of substances known to cause
cancer, reproductive toxicity, and other
injuries. Control dust and fumes at the
source where possible.
In this regard, use engineering controls,
good work practices and follow the
recommendations of the material
manufacturer/supplier, OSHA/NIOSH,
and occupational and trade
associations.
WARNING
Cutting masonry, concrete and other
materials with silica in their composition
may produce dust containing crystalline
silica. Silica is a basic component of
sand, quartz, brick clay, granite and
numerous other minerals and rocks.
Inhalation of airborne crystalline silica
can cause serious or fatal injury or
illness, such as kidney disease and
respiratory diseases, including silicosis
and lung cancer. California and some
other authorities have listed respirable
crystalline silica as a substance known
to cause cancer. OSHA has established
a maximum permissible exposure limit
for crystalline silica. When cutting
materials that may contain crystalline
silica, always follow the recommended
engineering controls and respiratory
precautions described in this instruction
manual.

WARNING
A water attachment kit is
provided with your cut-off
machine and should be
used to reduce dust
whenever wet cutting is
feasible. To reduce the
risk of serious or perma -
nent injury to the operator
or any bystanders from
exposure to potentially
harmful dust, the water
flow rate to the abrasive
wheel should be at least
20 fl. oz. (0.6 liters) per
minute.
WARNING
Inhalation of airborne crystalline silica
can cause serious or fatal injury or
illness, such as kidney disease and
respiratory diseases, including silicosis
and lung cancer. To reduce the risk of
serious or fatal illness, including kidney
disease, respiratory disease and
cancer, the operator and any bystanders
should always wear a respirator that is
approved by NIOSH for the material
being cut and appropriate for worksite-
specific conditions if wet cutting at the
flow rate recommended in this
instruction manual is not utilized or
cannot be confirmed. The respirator
must have an Assigned Protection
Factor sufficient to provide the level of
respiratory protection needed for the
material being cut and worksite-specific
conditions.
Even if wet cutting at the recommended
flow rate, an operator who is working
with the machine for more than two
hours in one day, along with any
bystanders, should always wear a
NIOSH-approved respirator that is rated
for the material being cut and
appropriate for worksite-specific
conditions.
Consult your employer for information
relating to the respirator needed for the
material you are cutting and your
worksite-specific conditions. Your
employer is likely to have in place an
OSHA-required respiratory protection
program and can provide information
regarding the type and level of
respiratory protection needed for your
worksite. Information also is available
from OSHA at www.OSHA.gov.
See the section on Respiratory
Protection in the chapter Sample
Applications in this instruction manual.
Consult and follow any federal, state or
local laws or regulations with respect to
dry and wet cutting, including any
requirements for engineering controls,
work practices and respiratory
protection to reduce exposure to
respirable crystalline silica or other
potentially harmful substances.
WARNING
Breathing asbestos dust is dangerous
and can cause severe or fatal injury,
respiratory illness or cancer, including
mesothelioma. The use and disposal of
asbestos-containing products are strictly
regulated by 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-containing insulation or
