Using The Machine As A Loader - Komatsu WB93S-5 F50003 Operation & Maintenance Manual

3.12 USING THE MACHINE AS A LOADER

Always fasten the safety belt.
q
When the declutch push button is used, the machine keeps moving in neutral; to stop it, put on the
q
brakes.
The brake pedals can be used separately to reduce the steering radiuses; adopt this solution only if
q
absolutely necessary, at low speed and with lowered bucket.
Always warn the persons present in the worksite, even if they are authorized, by means of the horn.
q
IMPORTANT
The basic illustrations shown are those necessary for a correct use and exploitment of the machine; the
q
operator must get to know the controls, the described operating method, the use of the bucket position
indicator and learn how to organize work in a free area, using low gears, while seated in the driving
position.
3.12.1 BUCKET POSITION INDICATOR
Thanks to this indicator, the operator always knows the position of
the front bucket with respect to the ground; the horizontal position
of the bucket, parallel to the ground, is determined by the return of
the rod (1) to the reference level (2).
If the machine is provided with automatic RETURN-TO-DIG
device, the horizontal, parallel position of the bucket with respect
to the ground is determined by the sensor (3) located on the
cylinder and is reached when the sensor does not detect the rod
(1) any longer. In case of malfunction of the device, check and if
necessary carry out the required adjustments.
To adjust the sensor,
AUTOMATIC RETURN-TO-DIG DEVICE OF THE FRONT
BUCKET (if installed)".
3.12.2 ORGANIZING THE WORK AREA
If after a first inspection the area results to be uneven,
encumbered with big obstacles or characterized by considerable
height differences, before starting work it is advisable to level the
ground as much as possible, both for the loader and for the
vehicles to be loaded.
These preliminary operations will make work quicker, ensure
better results and at the same time reduce the operator's stress
and the wear of the machine components; furthermore, the time
necessary to load the trucks for the transport of the material will
be considerably reduced.
The area to be cleared from obstacles requires the use of a truck
positioned as indicated in the figure; for any other arrangement
the movements of the loader must be reduced as much as
possible.
