5. Important: All of the lifting equipment, including the hook and/or the shackle and any chains/slings/webs
between the machine and the load, will need regular inspections and testing by a competent person to
make sure they are fit for purpose.
6. Select power band L1,L2 or L3 dependant on the load being manoeuvred. The machine must be in power
band L1,L2 or L3 at all times.
Refer to: Operation > Instruments > General (Page 64).
7. Select creep speed travel. Maintain creep travel speed at all times.
Refer to: Operation > Drive Controls > Travel Speed Selector (Page 62).
8. Suspend the load as low to the ground as possible. The load must be visible at all times by the operator or
an appropriately trained person who is in contact with the operator at all times.
9. When you travel with the load, do not apply sharp adjustments to the controls.
Dumping Into a Truck
1. To prevent unnecessary manoeuvring, put the truck(s) in position, as shown. Refer to Figure 150.
2. Do not dump the material in one sudden movement. Roll the bucket forward in stages until it is empty.
Refer to Figure 151.
3. Use the joystick to move the bucket backwards and forwards to loosen any sticky material.
4. Keep the wind on your back. This keeps the dust away from you and your machine.
5. If the truck body is about as long as a buckets width, dump the load into the centre of the truck. If the truck
is two bucket widths long or more, fill the front of the truck first.
6. When you lift a large, heavy load:
6.1. Dump the load close to the bed of the truck.
6.2. Do not dump the load from height, this will damage the bed of the truck.
6.3. Put soil into the bed of the truck first to act as a cushion for the loads.
7. Move the truck into a position where it can easily be seen by the operator and lift multiple loads. This will
increase the operating efficiency and improve safety.
