Using The Machine As An Excavator - Komatsu WB93S-5 F50003 Operation & Maintenance Manual

USING THE MACHINE AS AN EXCAVATOR

3.13 USING THE MACHINE AS AN EXCAVATOR
The machine can be used as an excavator only after rotating the seat by 180° with respect to the correct
q
driving position; for the specific procedure, see "3.13.2 POSITIONING THE MACHINE FOR DIGGING
OPERATIONS". The machine is equipped with an acoustic alarm that is activated if the operator, with the
engine running, shifts the reverse gear lever from the neutral position with the seat rotated and not in
the correct driving position.
This is a danger signal, since it is absolutely forbidden to move the machine while working with the
backhoe equipment or in any case with the seat rotated by 180° with respect to the regular driving
position.
Remember that the operator is allowed to move the machine only while seated in the correct driving
position, with locked seat and fastened safety belt.
Always fasten the safety belt before starting any manoeuvre.
q
Always lower the stabilizers before starting any digging operation.
q
Before starting work, alert the persons in the vicinity by means of the horn integrated in the side
q
dashboard or in the left backhoe control lever, if the machine is equipped with backhoe servo controls.
3.13.1 POSITIONING THE BUCKET
ACCORDING TO THE WORK THAT
MUST BE CARRIED OUT
When introducing the bucket connection pins in the
q
couplings of the arm and of the thrusting arm, be careful to
the metal chips that may come off and cause serious injury.
Always wear safety goggles, thick gloves and helmet.
q
Avoid using your fingers to align the holes, since they may
q
be cut off in case of sudden or uncontrolled movements.
BUCKET POSITIONS
Two position options are available for the bucket:
Pos. 1: suitable for normal digging operations, ensures more
power to the bucket.
Pos. 2: suitable for operations on vertical walls, ensures the
maximum swing and the maximum digging height on
walls.
In this position the tearing force is reduced.
