Working with the Excavator End
Working with the Excavator End
General
WARNING When using the boom and dipper fully extended, take the following precautions, otherwise the
machine could get damaged or become unstable and become a danger to you and other people.
Make sure you do not exceed the working capacity of the boom at maximum reach. Slew the boom slowly
to prevent any chance of the machine becoming unstable. For the same reason avoid dumping downhill
if possible.
WARNING Care must be taken with machines installed with an extra long dipper as it may affect the stability
of the machine.
Before you start using the excavator, you must convert the machine into a safe and stable working platform.
Refer to: Preparing to Use the Excavator End (Page 62).
To use the excavator efficiently and safely you must know the machine and have the skill to use it. This
manual instructs you on the machine, its controls and its safe operation. It is not a training manual on the art
of excavating. If you are a new operator, get yourself trained in the skills of using the excavator before trying
to work with it. If you don't, you will not do your job well, and you will be a danger to yourself and others.
If you will be working with a labourer, make sure you both understand what each other will be doing. Learn and
use the recognised signalling procedures. Do not rely on shouting - he or she will not hear you.
Make sure the correct bucket for the job is installed. Refer to: Buckets (Page 95).
Preparing to Use the Excavator End
When choosing a digging position, avoid digging downhill if possible. When possible, dump the load on the
uphill side of the excavation. Both of these precautions will help to keep the machine stable.
When the machine is in the required position on the worksite, lower the dozer blade to the ground (if fitted).
Ensure you have complete field of vision before using the excavator end.
Lifting With the Excavator End
WARNING You must turn on the overload warning system before you use the excavator for object handling,
or a stability hazard could occur.
WARNING Ensure that the sling is vertical during lifting operations and not deflected from the vertical lift
path by other machine parts.
Figure 43.
Lifting operations must be carried out with the overload warning system turned on (if applicable).
Use a signalman when lifting with the excavator. Make sure you both understand and use the recognized
signals. Keep all persons clear of the load and machine while the load is on the excavator.
1. A bucket or quick coupler must be installed when lifting with the excavator to prevent the link swinging.
Check that the lifting load is not greater than the safe working load for the lifting equipment (e.g link lifting
eye, lifting shackle, sling etc.).
