Safety instructions for operation of earth moving machines
7.7.9 Before replacing the bucket blades of scrapers, make sure the buckets are set
down on a base avoiding tipping or damage.
7.7.10 Maintenance and repair work on scraper buckets may be carried out only if the lock
flap is secured.
7.7.11 Switch off all drives before carrying out maintenance and repair work.
An exception to this requirement is maintenance and repair work that cannot be carried out
without a drive. In case of danger, it must be possible to switch off the drive immediately
during this work.
7.7.12 Disconnect the battery before carrying out arc welding or before working on the
electric system of an earth moving machine fitted with an internal combustion
engine.
7.7.13 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.
7.7.14 Cover the battery with insulating material as you carry out repair work in the area of
the battery; do not place any tools whatsoever on the battery.
7.7.15 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 unauthorised start-up.
7.7.16 Open or remove protective devices of moving machine parts only if the drive has
been switched off and secured against unauthorised start-up.
Protective devices are e.g. engine covers, doors, protective screens, trims, etc.
7.7.17 Fit all the protective devices back on again correctly once assembly, maintenance
or repair work is over.
7.7.18 Welding work on load-bearing elements of the earth moving machine, e.g. lattice
booms, loader units, may be carried by only in compliance with the acknowledged
welding regulations.
7.7.19 Do not carry out any welding, boring or drilling on rollover protection structures
(ROPS) or canopies (FOPS) that could affect the stability of this equipment.
7.7.20 Any modification, such as welding the hydraulic or compressed-air system, may be
carried out only with the manufacturer's authorisation.
7.7.21 Before starting work on the hydraulic system, release the control and the back
pressures, and the pressure inside the tank.
7.7.22 Use only the hoses and lines prescribed by the manufacturer.
7.7.23 Install and route hydraulic hoses and lines correctly.
7.7.24 No smoking and no naked flames during refuelling.
