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: If the machine is equipped with a trailer-light kit,
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 the engine is stopped, the fuel valve is off, and
the drum is empty.
2. If the drum has accumulated any water, dump the
drum; refer to Dumping the Drum (page 24), 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 engine cowl and secure the cowl latches
(Figure 18).

Checking the Tires and Wheels
the appropriate air pressure for the tires as installed at
the factory.
Service Interval: Before each use or daily—Inspect the tires
and wheels.
Important: Always check the information
on the actual tires for the correct air pressure
requirement.
WARNING
Important: The most common cause of tire
trouble is under-inflation. Maintain full air
pressure.
Failure to maintain correct tire pressure may result
in tire failure and loss of control, resulting in
property damage and serious injury or death.
Tire Air Pressure
• 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.

Max 241 kPa (35 psi)
3. Ensure that the wheel lug nuts are torqued to 108 to
122 N-m (80 to 90 ft-lb).
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/Vehicle+Safety/Tires.
Note: Check the torque of the wheel lug nuts initially
and after towing.
Note: Torque the lug nuts in the sequence shown in
Figure 21.
Note: The various machines in this manual have different
weights; refer to Specifications (page 13) to ensure that the
tires on your machine meet or exceed the weight requirements
of your machine.

Adding Fuel
• Do not fill fuel containers inside a vehicle or on
a truck or trailer bed because interior carpets
or plastic truck bed liners may insulate the
container and slow the loss of any static charge.
• For best results, use only clean, fresh, unleaded gasoline
with an octane rating of 87 or higher ((R+M)/2 rating
method).
• Oxygenated fuel with up to 10% ethanol or 15% MTBE
by volume is acceptable.
• When practical, remove fuel-powered equipment
from the truck or trailer and fuel the equipment
with the wheels on the ground.
• Do not use ethanol blends of gasoline (such as E15
or E85) with more than 10% ethanol by volume.
Performance problems and/or engine damage may result
which may not be covered under warranty.
• If this is not possible, then refuel such
equipment on a truck or trailer from a portable
container, rather than from a fuel dispenser
nozzle.
• Do not use gasoline containing methanol.
• Do not store fuel either in the fuel tank or fuel containers
• If a fuel dispenser nozzle must be used, keep the
nozzle in contact with the rim of the fuel tank
or container opening at all times until fueling is
complete.
over the winter unless a fuel stabilizer is used.
• Do not add oil to gasoline.
DANGER
In certain conditions, fuel is extremely flammable
and highly explosive. A fire or explosion from fuel
can burn you and others and can damage property.
WARNING
• Fill the fuel tank outdoors, in an open area, when
the engine is cold. Wipe up any fuel that spills.
Fuel is harmful or fatal if swallowed. Long-term
exposure to vapors can cause serious injury and
illness.
• Never fill the fuel tank inside an enclosed trailer.
• Avoid prolonged breathing of vapors.
• Do not fill the fuel tank completely full. Add
fuel to the fuel tank until the level is no higher
than the screen on the filter in the fuel tank.
This empty space in the tank allows the fuel to
expand.
• Keep your face away from the nozzle and the
fuel tank or conditioner opening.
• Keep fuel away from your eyes and skin.
Important: Do not mix oil with fuel.
• Never smoke when handling fuel, and stay away
from an open flame or where fuel fumes may be
ignited by a spark.
Recommended Fuel
