FUEL AND CHEMICAL EXPOSURE WARNINGS
Gasoline engine exhaust and some of
its constituents, and some dust
created by power sanding, sawing,

chemicals know to cause cancer, birth
defects and other reproductive harm.
Someexamples ofthesechemicals are:
Lead from lead-based paints
Crystalline silica from bricks
Cement and other masonry products
Arsenic and chromium from chemically
treated lumber
Your risk from these exposures varies,
depending on how often you do this
type of work. To reduce your exposure
to these chemicals: work in a
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
serious damage to the
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 knowledgable
physician immediately or severe injury or
death can occur.

NEVER operate the engine with heat shields or
guards removed.
Keep fi ngers, hands hair and clothing away
from all moving parts to prevent injury.
DO NOT remove the engine oil drain plug while the

CAUTION
NEVER touch the hot exhaust manifold,
muffl er or cylinder. Allow these parts to cool
before servicing equipment.
ALWAYS keep clear of rotating or moving
parts while operating the screed.
NEVER disconnect any emergency or safety devices.
These devices are intended for operator safe ty.
Disconnection of these devices can cause severe injury,
bodily harm or even death. Disconnection of any of these
devices will void all warranties.
CAUTION
NEVER allow passengers or riders on the screed during
operation.
NEVER lubricate components or attempt service on a
running machine.

maximum allowable.
FUEL SAFETY
DANGER
A strap or chain can be attached to these hooks, allowing
a forklift or crane to lift the screed 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

tow a trailer with defective hitches, couplings, chains, etc.
Trailer tires should be infl ated to 50 psi cold.
SAFETY INFORMATION
DO NOT start the engine near spilled fuel or combustible
fl uids. Fuel is extremely fl ammable and its vapors can
cause an explosion if ignited.
ALWAYS refuel in a well-ventilated area, away from
sparks and open fl ames.
ALWAYS use extreme caution when working with
fl ammable liquids.
DO NOT fi ll the fuel tank while the engine is running
or hot.
DO NOT overfi ll tank, since spilled fuel could ignite if it
comes into contact with hot engine parts or sparks from
the ignition system.
Store fuel in appropriate containers, in well-ventilated
areas and away from sparks and fl ames.
NEVER use fuel as a cleaning agent.
DO NOT sm oke aroun d or near the
equipment. Fire or explosion could result
from fuel vapors or if fuel is spilled on a
hot engine.
TRANSPORTING SAFETY
NEVER allow any person or animal to
stand underneath the equipment while
lifting.
NEVER lift or transport screed with
personnel standing on the screed.
Use proper heavy lifting procedures when lifting the
screed.
NOTICE
Machine can be transported on fl atbed truck of proper
weight capacity.
The easiest way to lift the screed is to attach lifting hooks
to the screed frame. Lifting hooks should be placed at
equal distances from each end of the screed.
CAUTION
device must be capable of lifting at least this amount.
Always make sure crane or lifting device has been
properly secured to the lifting hooks on the equipment.
ALWAYS shutdown engine before transporting.
NEVER lift the equipment while the engine is running.
Tighten fuel tank cap securely and close fuel cock to
prevent fuel from spilling.
Use adequate lifting cable (wire or rope) of suffi cient
strength.
DO NOT lift machine to unnecessary heights.
ALWAYS tie down equipment during transport by
securing the equipment with rope.
TOWING SAFETY
CAUTION
Check with your local county or state safety
towing regulations, in addition to meeting
Department of Transportation (DOT)
Safety Towing Regulations, before towing
your screed.
In order to reduce the possibility of an accident while
transporting the screed on public roads, ALWAYS
