the appropriate air pressure for the tires as installed at
the factory.
Service Interval: Before each use or daily—Inspect the tires
and wheels.
After each use—Torque the lug nuts to 108 to 122
N∙m (80 to 90 ft-lb) after towing.
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 underinflation. 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.
Model
Tire pressure
68017C
Max 414 kPa (60 psi)

DANGER
WARNING
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.
Fuel is harmful or fatal if swallowed. Long-term
exposure to vapors can cause serious injury and
illness.
• Fill the fuel tank outdoors, in an open area, when
the engine is cold. Wipe up any fuel that spills.
• Avoid prolonged breathing of vapors.
• Keep face away from nozzle and fuel tank or
conditioner bottle opening.
• Never fill the fuel tank inside an enclosed trailer.
• Do not fill the fuel tank completely full. Add
fuel to the fuel tank until the level is 6 to 13 mm
(1/4 to 1/2 inch) below the bottom of the filler
neck. This empty space in the tank allows the
fuel to expand.
• Avoid contact with skin; wash off spillage with
soap and water.
Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the machine to provide
the following benefits:
• Never smoke when handling fuel, and stay away
from an open flame or where fuel fumes may be
ignited by a spark.
• Keeps fuel fresh during storage of 90 days or less. For
longer storage it is recommended that the fuel tank be
drained.
• Store the fuel in an approved container and keep
it out of the reach of children. Never buy more
than a 30-day supply of fuel.
• Cleans the engine while it runs
• Do not operate without entire exhaust system in
place and in proper working condition.
which causes hard starting
• Eliminates gum-like varnish buildup in the fuel system,
Important: Do not use fuel additives containing
methanol or ethanol.
Add the correct amount of gas stabilizer/conditioner to
the gas.
DANGER
In certain conditions during fueling, static
electricity can be released causing a spark which
can ignite the fuel vapors. A fire or explosion from
fuel can burn you and others and can damage
property.
Note: A fuel stabilizer/conditioner is most effective
when mixed with fresh fuel. To minimize the chance of
varnish deposits in the fuel system, use fuel stabilizer at
all times.
• Always place fuel containers on the ground away
from your vehicle before filling.
• 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.
• When practical, remove gas-powered equipment
from the truck or trailer and refuel the equipment
with its wheels on the ground.
• 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.
• If you must use a fuel-dispenser nozzle, keep the
nozzle in contact with the rim of the fuel tank
or container opening at all times until fueling is
complete.
