REPORTING SAFETY DEFECTS
If you believe that your vehicle has a defect which could cause a crash or could cause injury or death, you should
immediately inform the National Highway Traffic Safety Administration (NHTSA) in addition to notifying Crown
Construction Equipment.
If NHTSA receives similar complaints, it may open an investigation, and if it finds that a safety defect exists in a group of
vehicles, it may order a recall and remedy campaign. However, NHTSA cannot become involved in any individual
problems between you, your dealer, or Crown Construction Equipment.
To contact NHTSA you may either call the Auto Safety Hotline toll free at
1-800-424-9393 (366-0123 in Washington, DC area) or write to:
NHTSA
U.S. DEPARMENT of TRANSPORTATION
400 7th Street SW, (NSA-11)
Washington, DC
20590
You can also obtain other information about motor vehicle safety from the Hotline.
CALIFORNIA –Proposition 65 Warning
Engine exhaust and some of its constituents and some dust created by power sanding, sawing, grinding, drilling and
other construction activities contains chemicals known to the State of California to cause cancer, birth defects and other
reproductive harm.
Some examples of these chemicals 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:
ALWAYS work in a well ventilated area, and work with approved safety equipment, such as dust masks that are specially
designed to filter out microscopic participles.

4.1 TO THE NEW OPERATOR OR OWNER
The Crown Construction Equipment Concrete Mixer is
designed to efficiently combine water, aggregate and
cement into a mixture for forming concrete. It is the
responsibility of the operator to be familiar with the machine
before starting.
It is the responsibility of the owner or operator to read this
manual before starting. Follow all safety instructions exactly.
Safety is everyone´s business. By following recommended
procedures, safe working environment is provided for the
operator, bystanders and the environment.
Many features incorporated into this machine are the result
of suggestions made by customers like you. Read this manual
carefully to learn how to operate the machine safely and
how to set it to provide maximum mixing efficiency. By
following the operating instructions in conjunction with a
good maintenance program, your Mixer will provide many
years of trouble-free service.

18
4.2 HOW THE MACHINE WORKS
The Concrete Mixer consists of a large rotating drum
with internal paddles for combining cement,
aggregate and water into a mixture for forming
concrete. The enclosure on the back end houses the
gas engine for turning the mixing drum. A set of
pulleys and drive belt within the transmits rotational
power to the drum bly allows the operator to tilt the
drum to the required position for mixing and
emptying. An extendable hitch on the front of the
frame allows the hitch to extend for towing and
retracts during operation.

4.3 PRE-OPERATION CHECKLIST
Efficient and safe operation of the Mixer requires that
each operator reads and understands the operating
procedures and all related safety precautions outlined in
this section. A pre-operation checklist is provided for the
operator. It is important for both personal safety and
maintaining the good mechanical condition of the
machine that this checklist is followed.
Before operating the Mixer and each time there-after the
following areas should be checked off:
1. Gas Engine Units:
a) Check all fluid levels: fuel and engine oil.
Refuel or top up engine oil as required.
b) Check the tires and be sure that they are inflated
to the specified pressure.
c) Check the tension and alignment of drive belt.
Tension or align as required.
d) Check the engine speed at maximum. Be sure it
is set to give a drum rotation speed of 18 to 24
RPM.
e) Use the Emergency Stop switch to stop the
engine to be sure that it works. Repair or replace
if not functioning.
f) Lubricate machine per Maintenance Section.
g) Close and secure all guards, shields and hoods.
2. Electric motor units:
a) Check the tension and alignment of drive belt.
Tension and align as required.
b) Check the tires and be sure that they are inflated

4.4 PRE-START PROCEDURES
All machines are sent from the factory in a special
shipping configuration to prevent spilling oil or gas. As a
result, the following items must be done prior to starting
the machine:
1. Gas engine powered units:
a) Fill the engine crankcase whit its specified oil
(SAE 30W or 10W30 oil).
IMPORTANT
Engine warranty is void if the engine is run
without oil.
Refer to engine manual for oil specifications if
operating in unusual temperature conditions.
b) Fill the fuel tank with regular unleaded gas.
Do not use an ethanol blend.
c) Start the engine and set the high idle speed to
give a drum rotation speed of 18 to 24 RPM
IMPORTANT
The engine is supplied from the engine
manufacture with the high idle speed set at
approximately 3500 RPM and no gas or oil. As
a result, the engine is not run when it is
mounted to the Mixer. It is the responsibility
of the customer to add oil and gas, start the
engine and reset the high idle RPM to the
operating range (Refer the Maintenance
Section for procedure).
d) Be sure that Emergency Stop switch is
functioning properly
2. Electric motor powered units:
a) Have a licensed electrician provide power to the
motor. Use only a grounded cord with sufficient
capacity to carry the required load.
b) Have a licensed electrician wire up the motor if
it is not a 110-volt unit.
4.5 MACHINE BREAK-IN
