PROPOSITION 65 WARNING
Engine exhaust and some of
its constituents, and some dust created
by power sanding, sawing, grinding,
drillingandotherconstructionactivities
contains chemicals known to the State
of California to cause cancer, birth
defects and other reproductive harm.
Some examples of these chemicals are:
Leadfromlead-basedpaints.
Crystallinesilicafrombricks.
Cementandothermasonryproducts.
Arsenicandchromiumfrom chemically
treatedlumber.
Your risk from these exposures varies,
dependingonhowoftenyoudothistype
of work. To reduce your exposure to
these chemicals: work in aALWAYS
well ventilated area, and work with
approved safety equipment, such as
dust masks that are specially designed
to filter out microscopic particles.

SILICOSIS/RESPIRATORY WARNINGS
WARNING
SILICOSIS WARNING RESPIRATORY HAZARDS
Grinding/cutting/drilling of masonry, concrete, metal and
other materials with silica in their composition may give
off dust or mists 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
Grinding/cutting/drilling of masonry, concrete, metal and
other materials can generate dust, mists and fumes
containing chemicals known to cause serious or fatal
injury or illness, such as respiratory disease, cancer,
birth defects or other reproductive harm. If you are
unfamiliar with the risks associated with the particular
process and/or material being cut or the composition of
the tool being used, review the material safety data
sheet and/or consult your employer, the material
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, or other harmful
effects.
Control dust, mist and fumes at the source where
possible. In this regard use good work practices and
follow the recommendations of the manufacturers or
suppliers, OSHA/NIOSH, and occupational and trade
associations. Water should be used for dust
suppression when wet cutting is feasible. When the
hazards from inhalation of dust, mists and fumes cannot
be eliminated, the operator and any bystanders should
always wear a respirator approved by NIOSH/MSHA for
the materials being used.

SAFETY INFORMATION
DANGER
Engine fuel exhaust gases contain poisonous carbon
monoxide. This gas is colorless and odorless, and can
cause death if inhaled.
The engine of this equipment requires an adequate free
fl ow of cooling air. NEVER operate this equipment in any
enclosed or narrow area
where free fl ow of the air is
restricted. If the air fl ow is
restricted it will cause injury
to people and property and
serio u s dama g e to t he
equipment or engine.
NEVER operate the equipment in an explosive
atmosphere or near combustible materials. An
explosion or fi re could result causing severe
bodily harm or even death.
WARNING
If applicable, NEVER use your hand to fi nd
hydraulic leaks. Use a piece of wood or
cardboard. Hydraulic fl uid injected into the
skin must be treated by a knowledgeable
physician immediately or severe injury or
death can occur.
Accidental starting can cause severe injury
or death. ALWAYS place the ON/OFF
switch in the OFF position.
NEVER disconnect any emergency or safety devices.
These devices are intended for operator safety.
Disconnection of these devices can cause severe injury,
bodily harm or even death. Disconnection of any of these
devices will void all warranties.
CAUTION
Anytime the saw is lifted onto its nose or tilted fully
back, such as for maintenance access, the high end of
the saw MUST be blocked up to prevent the possibility
of crush injury.

recommendations. Match the blade RPM (blade shaft
RPM) to the recommended blade surface feet per minute
(SFPM).
Ensure the blade-mounting bolt is tightened to 125-175
foot lbs. of torque.
ALWAYS examine blade flanges for damage and
excessive wear.
Ensure the blade is marked with an operating speed

The easiest way to lift the saw is to utilize the lifting bale. A
strap or chain can be attached to the lifting bale, allowing
a forklift or crane to lift the saw up onto and off of a slab
of concrete. The strap or chain should have a minimum
of 2,000 pounds (1,000 kg) lifting capacity and the lifting
