Kubota LA340 Operator's Manual page 19

The machine can become unstable in wet or
thawing conditions and these conditions may
collapse under the weight of the machine and may
cause tipping-over of the machine.
• Never operate the machine or any equipment while
under the influence of alcohol or other drugs, or
while fatigued.
• When leaving the machine unattended, be sure to
lower the backhoe to the ground. Set the parking
brake, then shut the engine off and remove the key.
3. Precautions of the backhoe while
driving the tractor on the road
• Raise and center the boom, close the dipperstick,
curl the bucket, and lock the boom before
transporting the machine.
• Check the local codes or regulations that may apply
to tractor, loader, and backhoe operation on public
streets or highways, before transporting or traveling
of the machine. Use the slow-moving-vehicle (SMV)
emblem and warning flashers as required.
4. Precautions for servicing the
backhoe
• Before disconnecting the hydraulic lines, relieve all
hydraulic pressure by moving the controls.
• Always use personal protection device such as
safety goggles and ear protection when servicing or
repairing the machine.
• Lower the backhoe to the ground and shut the
engine off before servicing of the backhoe.
• When servicing or repairing pins in cylinder ends,
bucket, and so on, always use a brass drift and
hammer. Failure to service or repair pins using a
brass drift and hammer could result in injury from
flying metal fragments.
• To avoid serious personal injury, keep clear of
working area of the backhoe.
• When servicing
underneath, do not get under the machine while it is
being held with only the bucket, backhoe, or
stabilizers. Securely support the machine with jack
stands.
• For your safety, do not work under any hydraulically
supported machine
supported machine elements can settle, suddenly
leak down, or be accidentally lowered.
• Escaping hydraulic fluid under pressure can obtain
sufficient force to penetrate the skin, which cause
serious personal injury.
Before applying pressure to the hydraulic system,
be sure that all connections are tight and that all
lines, the pipes and the hoses are not damaged.
Hydraulic fluid escaping from a very small hole can
be almost invisible. Do not use hands to search for
BX23S, LA340, BT603
or checking the backhoe
elements. Hydraulically

suspected leaks. Use a piece of cardboard or
wood.
If injured by escaping fluid, see a doctor at once.
Serious infection or allergic reaction will develop if
proper medical treatment is not administered
immediately.
• Do not tamper with any setting of the pressure of
the control valve and the relief valve of the
backhoe. The pressure of the relief valve is preset
at the factory. Changing the setting of the pressure
of the relief valve can cause overloading of the
backhoe and the tractor, and serious personal injury
or death may result.
• Do not modify the backhoe for any reason.
Modifying the backhoe can cause an unstable
condition of combination of the tractor, the loader,
and the backhoe, and serious personal injury or
death may result.
