Safety instructions for operation of earth moving machines
Before replacing the bucket blades of scrapers, ensure that the buckets are set
down on a base avoiding tipping or damage.
Maintenance and repair work on scraper buckets may be performed only if the lock
flap is secured.
Switch off all drives before performing maintenance and repair work.
An exception to this requirement is maintenance and repair work that cannot be performed
without a drive. In case of danger, it must be possible to switch off the drive immediately
during this work.
Disconnect the battery before performing arc welding or before working on the elec-
trical system of an earth moving machine fitted with an internal combustion engine.
First remove the negative terminal, and then the positive terminal as you disconnect
the battery. Proceed in the reverse order as you reconnect the battery.
Cover the battery with insulating material as you perform repair work in the area of
the battery; do not place any tools whatsoever on the battery.
In the case of earth moving machines with electric drives, switch off the electric
equipment and if necessary, the movable connecting lines as well, and secure
against unintentional or unauthorized start-up.
Open or remove protective devices of moving machine parts only if the drive has
been switched off and secured against unauthorized start-up.
Protective devices are, for example, engine covers, doors, protective screens, trims, etc.
Fit all the protective devices back on again correctly once assembly, maintenance
or repair work is over.
Welding work on load-bearing elements of the earth moving machine, for example
lattice booms, loader units, may be performed only in compliance with the acknowl-
edged welding regulations.
Do not perform any welding, boring or drilling on rollover protection structures
(ROPS) or canopies (FOPS) that could affect the stability of this equipment.
Any modification, such as welding the hydraulic or compressed-air system, may be
performed only with the manufacturer's authorization.
Before starting work on the hydraulic system, release the control and the back pres-
sures, and the pressure inside the reservoir.
Use only the hoses and lines prescribed by the manufacturer.
Install and route hydraulic hoses and lines correctly.
No smoking and no open flames during refueling.
