Operation

Important:

Before operating, remove any debris from

the machine. Ensure that the area is clear of people.

Preparing to Tow the Machine

Important:

Ensure that your tow vehicle has towing

capacity for the weight of the machine.

Important:

Use a Class 2 or larger receiver.

Note:

Ensure that your tow vehicle has the appropriate hitch

to tow the machine; options include a 50 mm (2 inch) ball
hitch or a pintle hitch.

Note:

Ensure that the electrical connector of the tow vehicle

is compatible with the electrical connector of the machine.
The machine uses a standard 4-flat plug. If your tow vehicle
has a different type of plug, obtain an adapter from an
automotive parts store.

1.

Ensure that the motor is stopped, the machine is
unplugged, and the drum is empty.

2.

If the drum has accumulated any water, dump the
drum; refer to Dumping the Drum (page 20), steps 1,
3
4, and 5.

3.

Using the dump lever, position the drum so that it is in
the mix position (upright) and locked.

4.

Close the cowl and secure the cowl latches (Figure 12).

5.

Extend the axle; refer to Extending the Axle (page 15).

Checking the Tires and Wheels

Service Interval:

Before each use or daily—Inspect the tires

and wheels.

WARNING

Failure to maintain correct tire pressure may result
in tire failure and loss of control, resulting in
property damage and serious injury or death.

Check the tire pressure frequently to ensure
proper inflation. If the tires are not inflated to
the correct pressure, they will wear prematurely.

Inspect the tire condition before towing and
after any operating accident.

The DOT tire information is located on the side
of each tire. This information gives load and speed
ratings. Replacement tires should have the same
or better ratings. For more information go to
http://www.nhtsa.gov/Safety/Tires.

Note:

The various machines in this manual have different

weights; refer to Specifications (page 11) to ensure that the
tires on your machine meet or exceed the weight requirements
of your machine.

1.

Visually inspect the tires for damage and wear (Figure
13 
and Figure 14).
