water as required so that the fluid level is between
the upper and lower levels.
• To avoid sparks from an accidental short circuit,
always disconnect the ground cable (-) of battery
first and reconnect it last.

• Do not mount a tire on a rim. Only a qualified
person should mount a tire on a rim with the proper
equipment.
• Always maintain the correct tire pressure. Do not
inflate the tires above the recommended pressure
shown in Inflation pressure of tires on page 97.
• Securely support the tractor when either changing
wheels or adjusting the width of wheel tread.
• Make sure that the wheel bolts have been tightened
to the specified torque.
(See WHEEL ADJUSTMENT on page 97)
• Do not work under any hydraulically supported
devices. They can settle, suddenly leak down, or be
accidentally lowered. If it is necessary to work
under the tractor or any machine elements for
servicing or adjustment, securely support them with
stands or suitable blocking beforehand.
• Escaping hydraulic fluid under pressure obtains
sufficient force to penetrate skin, so escaping
hydraulic fluid under pressure can cause serious
personal injury. Before disconnecting the hydraulic
lines, be sure to release all residual pressure.
Before applying pressure to the hydraulic system,
make sure that all connections are tight and that all
lines, pipes, and hoses are free of damage.
• Hydraulic fluid escaping from pinholes may be
invisible. Do not use hands to search for suspected
leaks. Use a piece of cardboard or wood to search
for suspected leaks. You should use safety goggles
or other eye protection. If injured by escaping fluid,
see a medical doctor at once. Hydraulic fluid will
produce gangrene or severe allergic reaction.

• Do not open high-pressure fuel system.
High-pressure fluid remaining in fuel lines can
cause serious injury. Do not disconnect nor attempt
to repair fuel lines, sensors, or any other
components between the high-pressure fuel pump
and injectors on engines with high-pressure-
common-rail-fuel-system.
• To avoid hazardous high voltage, turn the key
switch to the “OFF” position if it is necessary to
check to repair the computer, harness, or
connectors.
• During the diesel-particulate-filter (hereinafter called
DPF) regenerating operations, the exhaust gases,
and the exhaust filter components reach
temperatures hot enough to burn people, or ignite
or melt common materials.
• Keep the tractor away from people, animals, or
structures which may be susceptible to harm or
damage from hot exhaust gases.
