Operation

Safety for children

A stop logo indicating important informationChildren are normally attracted to machines and their normal operation. If children are in the vicinity of the machine and are not at a suitable distance and in the field of vision of the operator, this can lead to serious accidents or even death of the children.

Always observe the following rules of conduct:

  • Never assume that children will remain where you last saw them.
  • Keep children far away from the working area and always under the supervision of other responsible adults.
  • Be vigilant and switch the machine off when children enter the working area.
  • Never let children drive with you on your machine, there is no safe place for passengers. Children could fall off the machine and be run over or affect the control of the machine.
  • Children must never operate the machine, even under supervision of an adult.
  • Never let children play on the machine or attachments.
  • Be particularly careful when manoeuvring. Look behind and down below on the machine and ensure that there are no children in the manoeuvring area.
  • Before leaving the machine, park it so that it cannot move. When leaving the machine (e.g. for breaks or at the end of work), stop the engine, remove the key and close the cab door, if present.

Guiding the operator

  • If the operator’s working and driving area is obscured, the operator must be supported by a guide.
  • The guide must be capable of performing this kind of work.
  • Before starting work, the guide and the operator must agree the necessary signals.
  • The guide’s position must be clearly visible by the operator.
  • The operator must stop the excavator immediately if the eye contact to the guide is interrupted. –> As a rule, either the excavator or the guide may move, never both at once!

Working in the vicinity of overhead power lines

When working with the excavator in the vicinity of overhead power lines and tram lines, a minimum distance as specified in the following table must be maintained between the excavator and its attachments and the power line.

Rated voltage [V] Safe distance [m]
  up to 1 kV 1.0 m
over 1 kV up to 110 kV 3.0 m
over 110 kV up to 220 kV 4.0 m
over 22o kV up to 380 kV or when rated voltage is unknown 5.0 m

If safe distances can not be maintained, the power lines must be switched off in coordination with their owner or provider and secured against making them live again.

When approaching overhead power lines, any possible movements of the excavator must be taken into consideration.

Unevenness of the ground or sloping the excavator can reduce the safe distance.

Wind can cause the overhead power lines to sway, thus reducing the safe distance.

In case of power cross-over, leave the danger zone with the excavator, if possible, by taking suitable measures. If this is not possible, do not leave the operator’s place, warn any approaching persons of the danger, and have the power switched off.

Working in the vicinity of underground power lines

Before starting with excavation work, the owner of the excavator or the person responsible for the work must check if there are any underground power lines in the proposed working area.

If there are underground power lines present, the position and routing of the power lines must be determined together with the owners or operators and the required safety measures must be determined.

If power lines are encountered or accidentally damaged, the operator must stop working immediately and inform the responsible person.

Bleeding the fuel system

Image of a pointer indicating an important instructionIf the excavator fuel tank was run empty or the water separator was cleaned, the fuel system must be bled.

  • To bleed the fuel system, move the starter switch to the RUN position. The electrical fuel pump will bleed the fuel system automatically within approx. 60 s.
  • If the bleeding was insufficient, the engine will stop again. In this case repeat the procedure.

Changing the excavator buckets

1. Rest the bucket lightly on level ground (to avoid putting pressure on the bucket pins).

2. Remove the two lynch pins.

3. Push bucket pins out with large screwdriver (do not hit with hammer). If they don’t slide easily reduce pressure from arm. Don’t allow removed bucket pins to collect dirt or grit.

4. Lift boom up, away from bucket.

5. Place new bucket under links.

6. Lower boom to line up holes, making small adjustments as necessary.

7. Slide bucket pin in by hand (it should slide in easily, no hammering) and fit pin. (Note: some buckets have lynch pin locators on opposite side).

 

8. Lift bucket in the air.

9. Lower rear link (crowd bucket) and line up bucket pin and link by hand.

10. Slide bucket pin in, wiggling bucket if necessary and fit lynch pin.

!!! IMPORTANT: Injury risk – keep fingers out of holes !!!
