MC64SK/PK CONCRETE MIXER • OPERATION MANUAL — REV. #0 (07/20/22) — PAGE 3
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.

MIXER SAFETY
DANGER

NEVER operate the equipment in an
explosive atmosphere or near combustible
materials. An explosion or fire could result
causing severe bodily harm or even death.

DO NOT mix flammable or explosive substances.
WARNING

NEVER place your hands inside the drum
while starting or operating this equipment.

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.

Before operating the mixer, ensure that the safety grate
is in position and correctly fitted.
CAUTION

NEVER lubricate components or attempt service on a
running machine.
NOTICE

ALWAYS keep the machine in proper running condition.

ALWAYS ensure the mixer is on level ground before mixing.

Fix damage to the machine and replace any broken
parts immediately.

DO NOT tip the mixer onto the drum mouth when the
drum is rotating.

Ensure the drum is rotating while filling and emptying
the drum.
ALWAYS store equipment properly when it is not being
used. Equipment should be stored in a clean, dry location
out of the reach of children and unauthorized personnel.
ALWAYS
make sure the mixer is clean of dried materials.
DO NOT
allow material to build up inside the drum. Keep
the drum, frame and wheels clean. Excess debris can
fall off on the highway and/or build up on the frame and
wheels, creating an unbalanced condition leading to
premature metal fatigue.
ENGINE SAFETY
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 flow of cooling air. NEVER
operate this equipment
in any enclosed or narrow
area where the free flow
of air is restricted. If the air
flow is restricted it will cause
injury to people and property
and serious damage to the
equipment or engine.
WARNING
DO NOT
place hands or fingers inside the engine
compartment when the engine is running.
NEVER
operate the engine with heat shields or
guards removed.
Keep fingers, hands, hair and clothing away
from all moving parts to prevent injury.
DO NOT remove the engine oil drain plug
while the engine is hot. Hot oil will gush out of the oil
tank and severely scald any persons in the general area
of the mixer.
CAUTION
NEVER touch the hot exhaust manifold,
muffler or cylinder. Allow these parts to cool
before servicing the equipment.

Make certain the operator knows how to and is capable
of turning the engine OFF in case of an emergency.

SAFETY INFORMATION
NOTICE

NEVER run the engine without an air filter or with a dirty
air filter. Severe engine damage may occur. Service the
air filter frequently to prevent engine malfunction.

NEVER tamper with the factory settings
of the engine or engine governor. Damage
to the engine or equipment can result
if operating in speed ranges above the
maximum allowable.
FUEL SAFETY
DANGER

DO NOT start the engine near spilled fuel or combustible
fluids. Fuel is extremely flammable and its vapors can
cause an explosion if ignited.

ALWAYS refuel in a well-ventilated area, away from
sparks and open flames.

ALWAYS use extreme caution when working with
flammable liquids.

DO NOT fill the fuel tank while the engine is running
or hot.

DO NOT overfill the tank, since 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 flames.

NEVER use fuel as a cleaning agent.

DO NOT smoke around or near the
equipment. Fire or explosion could result
from fuel vapors or if fuel is spilled on a
hot engine.
TRANSPORTING SAFETY
CAUTION

NEVER allow any person or animal to stand underneath
the equipment while lifting.
NOTICE

ALWAYS make sure forklift forks are inserted as far as
possible into the pockets (if applicable) when lifting the mixer.
ALWAYS shut down the engine before transporting.
NEVER lift the equipment while the engine is running.

Tighten the fuel tank cap securely and close the fuel
cock to prevent fuel from spilling.
DO NOT lift the machine to unnecessary heights.
ALWAYS
tie down equipment during transport by
securing the equipment with rope.
NEVER
tip the engine to extreme angles during lifting
as this may cause oil to gravitate into the cylinder head,
making the engine difficult to start.
TOWING SAFETY
CAUTION
In addition to meeting
Department of Transportation
(DOT) safety towing regulations,
check your local
county or state safety towing regulations before towing
the mixer.

In order to reduce the possibility of an accident while
transporting the mixer on public roads, ALWAYS
make
sure the towing vehicle is mechanically sound and in
good operating condition.
ALWAYS
shut down the engine before transporting and
place the fuel valve in the OFF position.
ALWAYS inspect the hitch and coupling for wear.
NEVER
tow a mixer with defective hitches, couplings, chains, etc.

Check the tire air pressure on both towing vehicle and
mixer.
Mixer tires should be inflated to 50 psi cold.
Also check the tire tread wear on the vehicle and mixer.
ALWAYS make sure the mixer is equipped with a
safety
chain.
ALWAYS properly
attach the mixer’s safety chains to
the towing vehicle.
The maximum speed for highway towing is 55 MPH
unless
posted otherwise. Recommended off-road towing is not to
exceed 15 MPH or less depending on type of terrain.

Avoid sudden stops and starts.These can cause skidding
or jackknifing. Smooth, gradual starts and stops will
improve towing.
