PROPOSITION 65 WARNING

DSGPULW DUOSCREED • OPERATION MANUAL — REV. #8 (06/12/23) — PAGE 3

SILICOSIS WARNING

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.Inaddition, 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

ENGINE SAFETY

DANGER



The engine fuel exhaust gases contain poisonous carbon

monoxide. This gas is colorless and odorless, and can

cause death if inhaled.



The engine of this screed

requires an adequate, free

 ow of cooling air. NEVER

operate this equipment in

any enclosed or narrow area

where free  ow of the air is

restricted. If the air  ow is

restricted it will cause injury

to people and property and serious damage to the

equipment or engine.



When operating the screed outdoors, DO NOT place the

screed near doors, windows or vents that could allow

carbon monoxide to enter and build up in occupied

spaces.

WARNING



Operation of the screed may create sparks that can

start  res around dry vegetation. A spark arrestor may

be required. The operator should contact local fire

agencies for laws or regulations relating to  re prevention

requirements.

CAUTION



NEVER touch the hot exhaust manifold,

muf er or cylinder. Allow these parts to cool

before servicing the screed.

NOTICE



NEVER run the engine without an air  lter or with a dirty

air  lter. Severe engine damage may occur. Service the

air  lter frequently to prevent engine malfunction.



NEVER tamper with the factory settings of

the engine or engine governor. Damage to

the engine or screed can result if operating

in speed ranges above the maximum

allowable.

DANGEROUS

GAS FUMES

FUEL SAFETY

DANGER

DO NOT

add fuel to equipment if it is placed inside truck

bed with plastic liner. Possibility exists of explosion or

 re due to static electricity.

NEVER

start the engine near spilled fuel or combustible

 uids. gasoline fuel is extremely  ammable and its

vapors can cause an explosion if ignited.

ALWAYS

refuel in a well-ventilated area, away from

sparks and open  ames.

ALWAYS

use extreme caution when working with

 ammable liquids.

NEVER

fill the fuel tank while the engine is

running or hot.

NEVER

over ll the fuel tank. Spilled fuel can 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  ames.

NEVER use fuel as a cleaning agent.

NEVER smoke around or near the

ENVIRONMENTAL SAFETY/DECOMMISSIONING

NOTICE

Decommissioning is a controlled process used to safely

retire a piece of equipment that is no longer serviceable.

If the equipment poses an unacceptable and unrepairable

safety risk due to wear or damage or is no longer cost

effective to maintain (beyond life-cycle reliability) and is to

be decommissioned (demolition and dismantlement), be

sure to follow the rules below:

NEVER

pour waste or oil directly onto the ground, down

a drain, or into any water source.

Contact your country’s Department of Public

Works or recycling agency in your area and

arrange for proper disposal of any electrical

components, waste or oil associated with

this equipment.

When the life cycle of this equipment is over, remove

the battery and bring it to an appropriate facility for lead

reclamation. Use safety precautions when handling

batteries that contain sulfuric acid.



When the life cycle of this equipment is over, it is

recommended that the frame and all other metal parts

be sent to a recycling center.

Metal recycling involves the collection of metal from

discarded products and its transformation into raw

materials to use in manufacturing a new product.

Recyclers and manufacturers alike promote the process

of recycling metal. Using a metal recycling center

promotes energy cost savings.
