EM-70 PLASTER/MORTAR MIXER — TOWING GUIDELINES

Towing Safety Precautions

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.

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.

CAUTION

If the mixer tow bar is deformed or damaged, replace the

entire

 tow bar. 

NEVER

 tow the mixer with a defective

tow bar. There exists the possibility of the mixer separating
from the towing vehicle.

CAUTION

CAUTION

The following list of suggestions should be used when towing
the mixer:

Check with your county or state safety towing regulations
department before towing your 

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

 55

 MPH, however

before towing your mixer, check your local state, and
county vehicle towing requirements. Recommended off-
road towing is not to exceed 

10 

or

 15 MPH 

or less

depending on type of terrain.

Place 

chocked blocks underneath wheels to prevent

rolling

, while parked, if disconnected from towing

vehicle.

Inflate tires to correct pressure, inspect tires for cuts,
and excessive wear. See Table 4 (Tire Wear
Troubleshooting).

When towing of the mixer is required, place the drum in
the up position (mouth facing upwards) and lock the drum
latch.

Regularly Inspect

 Towing  Components

Replacing

Towing Components

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).

Mixer Tow Bar Vehicle  Connection (Pentle and Loop)

1. Make sure the bumper on the towing vehicle is equipped

to handle either a pentle 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

5 when securing the tow bar to the towing vehicle and to
the unit being towed.

ALWAYS 

make sure that the fuel valve lever is in the

OFF

 position (gasoline models only).

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.
