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.
■ ALWAYS inspect the hitch and coupling for wear. NEVER
tow the mixer with defective hitches, couplings, chains etc.
Tow Bar to Vehicle Connection (Coupler Only)
■ CHECK the tire air pressure on both the towing vehicle and
the trailer. Also check the tire tread wear on both vehicles.
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.
■ 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.
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.
■ 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.
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).
■ Place chocked blocks underneath wheels to prevent rolling,
while parked, if disconnected from towing vehicle.
Mixer Tow Bar Vehicle Connection (Pentile and Loop)
■ 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).
PAGE 16 — EC-42S
1. Make sure the bumper on the towing vehicle is equipped
to handle either a pentile or loop type tow bar
configuration.
2. After tow bar has been connected to mixer (see next
page), secure either type of tow bar to the towing vehicle,
following state and county towing regulations.
3. As a minimum, use a 1/2-inch bolt and nylock nut grade

3.
If the towing vechicle is equipped with a ball socket, smear
socket periodically with multi-purpose grease. This will keep
the ball socket well lubricated.
Periodically oil pivot points and clamp face surfaces of
coupler with SAE 30 WT. motor oil.
When parking or storing your mixer. Keep the coupler off
the ground so dirt will not build up in the ball socket.
2.
Use Poleyrex EM (Exxon Mobil) or equalivant lubricant.
Clean grease fitting, apply grease gun to fitting (1/2 shot).
Remember too much grease or injecting grease too quickly
can cause premature bearing failure. Slowly apply the
recommended amount of grease, taking a miniute or so to
apply.
Wheel Bearings
1.
Grease Fittings (Zerk) Maintenance (Mixer)
There are 3 grease (Figure 26) fittings that will require
lubrication. Lubricate these fittings once a week. Use lithium
base grease, grade N0.1.
After every 3 months of operation, remove the hub dust cap
and inspect the wheel bearings (Figure 28). Once a year,
or when required, disassemble the wheel hubs remove
the old grease and repack the bearings forcing grease
between rollers, cone and cage with a good grade of high
speed wheel bearing grease (never use grease heavier
than 265 A.S.T.M. penetration (“No. 2.”)

EC-42S CONCRETE MIXER — MAINTENANCE (MIXER)
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:
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 29) 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 8 (Tire Wear Troubleshooting) will help pinpoint the
causes and solutions of tire wear problems.
CAUTION:
NOTE
ALWAYS wear safety glasses
when removing or installing force
fitted parts. Failure to comply may
result in serious injury.

EC-42S 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 30. 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
NEVER! use an pneumatic air gun
to tighten wheel lug nuts.
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
