STOW CMS-64S CONCRETE MIXER — GENERAL INFORMATION
Application
This mixer is only intended for the production of concrete .
The mixer must be used for its intended purpose and is not
suitable for the mixing of flammable or explosive
substances. The mixer must not be used in an explosive
atmosphere. Use Table 4 (Mixing Hints) as a guide when
mixing concrete for various applications.
Power Plants
The STOW CMS-64S mixer can be powered by either a
Honda GX-240 gasoline engine or a 1.5 HP electric motor.
Refer to Table 2 to for specific engine or electric motor data
information.
Electrical
If mixer is equipped with an electric motor , make sure that
the power being supplied to the motor corresponds to the
voltageratinglabelon themotor.Supplying thewrongvoltage
to the electric motor will cause severe electrical damage to
the motor.
Always make sure the OFF/ON switch on the electric motor
is in the OFF position before applying power.
It is strongly recommended when inserting the mixer's
power cord into a receptacle, that a G.F.C.I.( Ground Fault
Current Interrupter ) receptacle be used (115 VAC
applications).
Extension Cables
The extension cable should be a 3-wire configuration that
includes a ground wire that conforms to UL code.The wire
cross section must be a minimum of 2.5 mm2. Choose an
extension cord of adequate current carrying capacity as ref-
erenced in Table 5. Remember cable distance affects the
current-voltage capacity of the extension cable.
Ensure that the extension cable is carefully laid out avoid-
ing
wet areas , sharp edges and locations where vehicles
might run over it. Avoid allowing the extension cable to be
trappedunderneath the mixer.
Unroll the extension cable fully or it will overheat and could
catch fire. Make sure that all extension cable connections
are dry and safe. Replace any defective or badly worn ex-
tension cable immediately.
Hardware
Check all hardware on the mixer before starting. Periodically
inspect all hardware. Loose hardware can contribute to early
componentfailureandpoorperformance. UseTable3asgeneral
guideline when the torqueing of mixer hardware is required.
Rememberto keep allmixer hardwarecomponents tight.
Engine Maintenance
Forbasicenginemaintenance,referto the enginemaintenance
sectioninthismanual.Foramoredetailedenginemaintenance,

STOW CMS-64S CONCRETE MIXER —TOWING GUIDELINES
To reduce the possibility of an accident while transporting
the mixer on public roads, always make sure that the mixer
towing components and the towing vehicle are in good
operating condition and both units are mechanically sound.
Thefollowinglist ofsuggestions shouldbe usedwhen towing
the mixer:
CAUTION:CAUTION:
CAUTION:CAUTION:
CAUTION:
Towing Safety Precautions
■ Check with your county or state safety
towing regulations department before
towingyour
mixer .
■ Make sure that the hitch and coupling of the towing vehicle
are rated equal to, or greater than the trailer "gross vehicle
weightrating"(GVWR).
■ ALWAYS inspect the hitch and coupling for wear. NEVER
towthemixer withdefectivehitches, couplings,chainsetc.
■ CHECK thetire air pressure on both the towingvehicle and
thetrailer.Alsocheckthetire tread wearon bothvehicles.
■ ALWAYS make sure the mixer is equipped with a "Safety
Chain".
■ ALWAYS attach trailer's safety chain to the frame of towing
vehicle.
■ ALWAYS make sure that the towing vehicle's directional,
backup, and brakelightsare workingproperly.
■ Remember in most cases the maximum speed unless
otherwise posted for highway towing is 45 MPH, however
beforetowingyourmixer,checkyourlocalstate,andcounty
vehicletowingrequirements. Recommendedoff-roadtowing
isnottoexceed10MPH or lessdependingontypeofterrain.
■ Place chockedblocks underneathwheelstoprevent rolling,
whileparked, if disconnected from towingvehicle.
■ Inflate tires to correct pressure, inspect tires for cuts, and
excessive wear.SeeTable 16 (TireWearTroubleshooting).
■ When towing of the mixer is required, place the drum in the
upposition(mouth facing upwards).
■ ALWAYS make sure that the fuel valve lever is in the OFF
position(gasoline modelsonly).
CAUTION:CAUTION:
CAUTION:CAUTION:
CAUTION:
If the mixer tow bar is deformed or damaged
replace entire tow bar.NEVER tow the mixer
with a defective tow bar. There exist the
possibility of the trailer separating from the
towing vehicle.
Tow Bar to Vehicle Connection (Coupler Only)
1. Check the vehicle hitch ball, and mixer's coupler for
signs of wear or damage. Replace any parts that are
wornor damaged before towing.
2. Use only a 2-inch ball diameter (towing vehicle), this
will match the mixer's 2-inch coupler. Use of any other
balldiameterwillcreateanextremelydangerouscondition
which can result in separation of the coupler and ball or
ball failure.
3. After tow bar has been connected to mixer (see next

■ Check wheel mounting lug nuts with a torque wrench.
Torque wheel lug nuts as described in the maintenance
sectionofthis manual.
■ Check tightness of U-clamp nuts, torque suspension
hardware as referenced in the maintenance section of this
manual.
■ Avoid sudden stops and starts.This can cause skidding, or
jackknifing. Smooth, gradual starts and stops will improve
gasmilage.

2. Route the safety chain through the holes just above the
tow bar, located on each side of the mixer stand.
Loop the chain together and place under the tow bar.
Secure the loop with the connector link.
3. Extend the safety chain along the length of the tow bar,
looping it through the tow bar's connector link. Remove
any excess chain slack.
4. Connect the free end of (clevis safety hook) the safety
chain to the towing vehicle.
Remember it is critical
that the length of the chain be properly adjusted , to
prevent the
draw bar and the front of the mixer stand
from dropping to the the ground (contact) in the event
the draw bar becomes disconnected from the towing
vehicle.

Protect the electric motor from dust as much as possible and
keepventilating openings clean.
The electric motor used in this mixer is a single-phase 1.5 HP
motor. Theinputvoltagerequirementforthismotor iseither115
or230VAConly.
Electric Motor Connection
A 12 inch electrical cable (Figure 2) with a pigtail at one end is
providedwiththeelectrical motor forhookupto a power source.
Table 1. shows the required NEMA connector for the desired
motor horsepower rating. In addition, Table 2 also shows the
matchingNEMAapprovedconnectorfor the required extension
cord.
ALWAYS , make certain that the power source required for the
electric motor is
correct and always use the correct NEMA
configuration plug.
