WARNING
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
water pressure recommended in this
instruction manual 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
water pressure, 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.
