Instructions for use
When the installing kit of the backhoe and the backhoe are mounted on the loader the work can be started.
The control levers of the backhoe will operate once the auxiliary hydraulics of the loader has been locked on.
Use the outriggers and the hydraulic locking of the backhoe; their operation is shown on the following pages.
Check the operating area and the attachment once more before starting work.
•
Check that the backhoe is intact and that all obstacles have been removed from the working area
before operation. Remember correct working methods and avoid unnecessary descending from the
loader.
•
Make sure that it safe to dig in the location. Find out if there are electric cables, water lines or similar
obstacles at a depth that can be reached with the digger.
•
Operate the backhoe only at well-lit areas.
•
Ensure that the loader and attachment are used in a safe manner and as intended.
•
Check the hydraulic hoses and their connections and that the hoses are not subjected to stretching
or squeezing at any position of the backhoe. Check regularly to ensure there are no hydraulic leaks.
Refer to Section 7 for maintenance instructions.
•
Operate the attachment only from the driver's seat or the operating position at next to the backhoe.
Do not let others to use the controls when working near the backhoe.
Turn the auxiliary hydraulics off whenever not operating the backhoe or when
transporting the backhoe. The control levers of the backhoe may be accidentally
operated, so that accidental movement of the backhoe may create a hazardous
situation.
Never go under a raised boom or the attachment. The backhoe components and the
loader boom move down even if the engine has been stopped.
6.1.
Using the outriggers
The backhoe is equipped with outriggers, which are intended to stabilize the backhoe during digging and
moving material to the sides. Using the backhoe is more efficient with the use of the outriggers, so it is
advisable to set them correctly. The outriggers are mounted so that its foot points forward from the loader.
Note that the left and the right ones are dissimilar.
The correct setting of the outrigger will also affect the hydraulic locking shown in the next section. The height
of the outriggers should be adjusted according to the terrain. There are several holes on the backhoe frame
and the outrigger. Use the cotter pin to lock the adjustment pin.
6.2.
Using the hydraulic locking of the backhoe
For more rigid mounting of the backhoe, it is locked onto the loader front frame by hydraulically operated
brackets. When the backhoe, its support bracket and hydraulic hoses are connected, the telescopic boom
of the loader must be retracted completely.
Lower the loader boom to as down as possible, which will lead to raising the loader front wheels off the
ground about 10 cm, if the outriggers are adjusted correctly. When using the hydraulic locking, the weight of
the front of the loader will be on the outriggers, giving more stability. Note that because of the support
bracket, on loaders equipped with the self-parallel system, the loader boom control lever should also be
moved sideways to lower or to lift the backhoe.
