INITIAL SERVICING
The engine (Figure 3) must be checked for proper lubrication and filled with fuel prior to operation. Refer to the manufacturers Engine manual for instructions & details of operation and servicing.
1. Fuel Filler Cap – Remove this cap to add unleaded gasoline to the fuel tank. Make sure cap is tightened securely. DO NOT over fill.
5. Fuel Valve Lever – OPEN to let fuel flow, CLOSE to stop the flow of fuel.
6. Choke Lever – Used in the starting of a cold engine, or in cold weather conditions. The choke enriches the fuel mixture.
7. Air Cleaner – Prevents dirt and other debris from entering the fuel system. Remove wing-nut on top of air filter cannister to gain access to filter element.
WARNING
WARNING
Adding fuel to the tank should be accomplished only when the engine is stopped and has had an
opportunity to cool down. In the event of a fuel spill, DO NOT attempt to start the engine until the fuel residue has been completely wiped up, and the area surrounding the engine is dry.
2. Throttle Lever – Used to adjust engine RPM speed (lever

8. Spark Plug – Provides spark to the ignition system. Set spark plug gap to 0.6 - 0.7 mm (0.028 - 0.031 inch). Clean spark plug once a week.
9. Muffler – Used to reduce noise and emissions.
while the engine is running or immediately after operating. NEVER operate the engine with the muffler removed.
10. Fuel Tank – Holds unleaded gasoline. For additional information refer to engine owner's manual.
NOTE
Operating the engine without an air filter, with a damaged air filter, or a filter in need of replacement will allow dirt to enter the engine, causing rapid engine wear.
WARNING
Engine components can generate extreme heat. To prevent burns, DO NOT touch these areas

The following list of suggestions should be used when towing the mixer:
Make sure that the hitch and coupling of the towing vehicle are rated equal to, or greater than the trailer "gross vehicle weight rating" (GVWR).
ALWAYS inspect the hitch and coupling for wear. NEVER tow the mixer with defective hitches, couplings, chains etc.
CHECK the tire air pressure on both the towing vehicle and the trailer. Also check the tire tread wear on both vehicles.
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 brake lights are working properly.
Remember in most cases the maximum speed unless otherwise posted for highway towing is 45 MPH, however before towing your mixer, check your local state, and county vehicle towing requirements. Recommended off-road towing is not to exceed 10 MPH or less depending on type of terrain.
.
Check wheel mounting lug nuts with a torque wrench. Torque wheel lug nuts as described in the maintenance section of this 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 gas milage.
Avoid sharp turns to prevent rolling.
CAUTION:CAUTION:
CAUTION:
CAUTION:CAUTION:
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 worn or 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 ball diameter will create an extremely dangerous condition which can result in separation of the coupler and ball or ball failure.
3. After tow bar has been connected to mixer (see next
page), attach mixer's coupler to the hitch ball on the towing vehicle securely and make sure the lock lever is in the down position (locked).
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.
Place
chocked blocks
while parked, if disconnected from towing vehicle.
Inflate tires to correct pressure, inspect tires for cuts, and excessive wear. See Table 16 (Tire Wear Troubleshooting).
When towing of the mixer is required, place the drum in the up position (mouth facing upwards).
ALWAYS make sure that the fuel valve lever is in the OFF position (gasoline models only).

The electric motor supplied with the mixer is configured from the factory for 115 VAC grounded operation. Make certain that the correct size grounded (3-wires) extension cord is used. See Table 5.
Motors can burn out when the line voltage falls 10% below the voltage rating of the motor. Failure to use proper voltage will cause the motor to overheat and actuate the overload switch.
If overload protection should actuate because of improper voltage or any other malfunction, turn the main switch on the motor to the "OFF" position and correct the problem, press the reset switch button, and turn the main switch to the "ON" position.

Thoroughly remove dirt and oil from the engine and control area. Clean or replace the air cleaner elements as necessary. Check and retighten all fasteners as necessary. Check the gearbox for oil leaks. Repair or replace as needed.
WEEKLY
Remove the fuel filter cap and clean the inside of the fuel tank.
Remove or clean the filter at the bottom of the tank.
Remove and clean the spark plug (Figure 24), then adjust the spark gap to 0.024 ~0.028 inch (0.6~0.7 mm). This unit has electronic ignition, which requires no adjustments.

Tires/Wheels/Lug Nuts
Tires and wheels are a very important and critical compo­nents of the trailer. When specifying or replacing the trailer wheels it is important the wheels, tires, and axle are prop­erly matched.
CAUTION:CAUTION:
CAUTION:
CAUTION:CAUTION:
DO NOT attempt to repair or modify a wheel. DO NOT install an inter-tube to correct a leak
through the rim. If the rim is cracked, the air pressure in the inter-tube may cause pieces of the rim to explode (break-off) with great force and can cause serious eye or bodily injury.
Tires Wear/Inflation
Tire inflation pressure is the most important factor in tire life. Pressure should be checked cold before operation. DO NOT bleed air from tires when they are hot. Check inflation pressure weekly during use to insure the maximum tire life and tread wear.
Suspension
The leaf suspension springs and associated components (Figure 30) should be visually inspected every 6,000 miles for signs of excessive wear, elongation of bolt holes, and loosening of fasteners. Replace all damaged parts (sus­pension) immediately. Torque locknut securing U-clamp to spring leaf between 45 and 50 ft.-lbs.
Table 9 (Tire Wear Troubleshooting) will help pinpoint the causes and solutions of tire wear problems.
CAUTION:
NOTE
ALWAYS
when removing or installing force fitted parts. Failure to comply may
result in serious injury.

STOW CMS-64S CONCRETE MIXER — MAINTENANCE (MIXER)
Lug Nut Torque Requirements
It is extremely important to apply and maintain proper wheel mounting torque on the trailer. Be sure to use only the fas­teners matched to the cone angle of the wheel. Proper pro­cedure for attachment of the wheels is as follows:
1. Start all wheel lug nuts by hand.
2. Torque all lug nuts in sequence. See Figure 31. DO NOT torque the wheel lug nuts all the way down. Tighten each lug nut in 3 separate passes as defined by Table 10.
3. After first road use, retorque all lug nuts in sequence. Check all wheel lug nuts periodically.
NOTE
Mixer Storage
For storage of the mixer for over 30 days, the following is recommended:
z
Drain the fuel tank completely, or add STA-BIL to the fuel.
z
Run the engine until the fuel is completely consumed.
z
Completely drain used oil from the engine crankcase and fill with fresh clean oil, then follow the procedures described in the engine manual for engine storage.
z
Clean the entire mixer and engine compartment.
z
Place the mixing drum in the down position (mouth facing downward).
NEVER!
