OPERATION
Safety rules for operation
The safety instructions (page 13) must be followed.
The machine may only be operated according to its approved use (page 16).
The machine may only be operated by instructed or trained personnel (page 11).
Do not operate the machine when under the influence of drugs, medication or alcohol. Stop operation when
getting tired. The operator must be physically capable of operating the machine safely.
The machine should only be operated if all protective devices are fully operational.
Before starting or working with the machine, make sure that there is no danger for any person nearby.
Before starting the machine, it must be checked for external damage and operability, and the pre-start checks
must be carried out. If failures are detected, the machine should only be taken into operation after the failures
have been repaired.
Wear tightly fitting working clothes in accordance with the trade association regulations.
During the operation of the machine, nobody except the operator is allowed to be inside the cab or get on the
machine.
For getting on and off, the swivel frame should be positioned in an angle which allows the operator to use the
crawler or the step (if applicable) to enter the cab.
Always stop the engine when leaving the cab. In exceptional cases, e.g. for troubleshooting, the cab can also
be left with the engine running. The operator must make sure that the left control console remains in an upright
position. The controls may only be used while the operator is sitting on the operator’s seat.
During operation, it is forbidden to stretch any part of the body out of the window or cab door, such as arms,
legs, or the body.
Prior to leaving the machine (e.g. for breaks or at the end of work) if at all possible park the machine on a firm,
flat and level ground, lower the attachment to the ground, place all control levers into neutral, switch off the
engine, set the parking brake, and prevent the machine from being restarted by taking the key.
Whenever work is interrupted, the bucket must always be lowered to the ground.
Do not allow the engine to run indoors, unless the room is equipped with an exhaust gas extraction system
or otherwise well ventilated. The exhaust gas contains carbon monoxide, a colourless, odourless, and lethal
gas.
Never crawl under the machine before the engine is stopped, the key is removed and the machine is secured
against moving.
Never crawl under the machine if it is only raised with the bucket or the dozer. Always use suitable supports.
To increase the machine’s stability, we recommend lowering the bulldozer blade onto the ground. The dozer
may only be used to increase stability if the dozer cylinder is equipped with a pipe safety valve.
The dozer control lever must not be moved into floating position in the process. The machine‘s stability is not
increased by the dozer while in the floating position.
