Off-road Operation

• Do not operate too close to quarry edges, ramp
edges, quay edges and soft edges that may col-
lapse under the machine weight.
• Always use the inter-axle differential lock and six-
wheel drive during off-road operation when there
is a risk of wheels slipping.
• Always engage the inter-axle differential lock be-
fore any of the wheels begin to slip.
• To cover difficult areas (e.g. soft mud) use the ar-
ticulation steering combined with the inter-axle
differential lock to move through the area in the
so called "duck waddle".
• Where the ground is particularly soft and there is
no space restriction, choose a new track for each
approach to avoid making deep tracks.
Loading And Tipping
The front and rear of the machine should be aligned
(no articulation) while tipping and loading in order to
ensure maximum vehicle stability.
• Do not operate, load or tip close to quarry edges,
ramp edges, quay edges and soft edges that may
collapse under the machine weight. Take special
care during loading and tipping as the machine
mass changes during these operations.
• When tipping a load from the bin, the centre of
gravity will change continuously and the condition
of the ground will determine the stability of the
machine.

• Special care should be taken when tipping sticky
material e.g. wet clay or freezing material, as this
material might be sticking to the bin. Material stic-
king to bin will influence the machine stability.
Refer to the machine's ability to signal warning for
tipping angle through the inclinometer. The roll per-
centage warning limit can be set between 5% and
20% (default of 15%).
Loading
Ensure there is sufficient space for the machine be-
fore entering confined areas.
Ensure that no personnel are near the machine or
loading area.
• Do not operate too close to quarry edges, ramp
edges, quay edges and soft edges that may col-
lapse under the machine's weight.
• Be aware of other machines and personnel when
entering or leaving the loading area.
• If a spotter is present follow only his instructions.
• Reverse up to a loading machine in a single,
straight manoeuvre so that you can maintain eye
contact at all times with the operator of the
loader.
• Steer the machine so that it is straight. The ope-
rator must have clear and unobstructed vision
through his rear view mirrors. If the machine is ar-
ticulated and not in the straight ahead position
the operator may find it difficult to observe the
spotter and the loading machines.
• Stop the machine on a firm level surface.
• Ensure that the bin is fully lowered so that the
load is not dumped into a bin which is supported
on the tip cylinders.
• Do not overload by exceeding the rated capacity
of the machine. The operator of the dump truck is
responsible for the size and mass of the load.
• Ensure the machine is loaded evenly. An uneven
load will cause tyre and axle damage.
Before moving off with a load ensure that it is safely
contained in the bin and no part of it can fall off. En-
sure that no parts of the load are protruding from
the bin.
