MAINTENANCE OF THE BACKHOE
CHECKING THE BACKHOE
DAILY
WARNING
To avoid serious injury or death:
• Never repair, service, or adjust any kind when
the hydraulic system is under pressure, when
the engine is running, or when any cylinder of
the backhoe is under load.
• Escaping hydraulic fluid under pressure can
obtain sufficient force to penetrate skin,
causing serious personal injury.
Before disconnecting lines, be sure to relieve all
pressure.
• Before applying pressure to the system, be sure
all connections are tight and that lines, tubes,
and hoses are not damaged.
• Fluid escaping from a very small hole can be
almost invisible. Use a piece of cardboard or
wood, rather than hands, to search for
suspected leaks.
• 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.

The backhoe is run by the tractor hydraulic system.
• Daily before operation, check the hydraulic level of
the tractor. If the hydraulic level of the tractor is low,
replenish the oil as described in 4. Checking the
transmission fluid level on page 120. Also check the
filter screen and change the hydraulic fluid as
recommended in 3. Replacing the transmission oil
filter on page 130 and 2. Changing the transmission
fluid on page 131.

• Check all hardware of the backhoe before daily
operation. Tighten the hardware of the backhoe to
torque values as specified in the GENERAL
TORQUE SPECIFICATION on page 144.
• With the engine off and the bucket on the ground,
inspect all hoses for cuts or wear. Check for signs
of leaks and make sure all fittings are tight.
• For safe operation, check that the mounting pin is
inserted into the hole of the main frame and the
slide bar before operation.
