steering,
hydraulic and
electrical systems
the earthmoving machine must be performed by specially trained skilled
personnel only.
Stability must be ensured at all times including during maintenance
work.
The operating devices must be secured from moving by being set down on the ground
or with
equivalent measures, e.g. supporting sleeves or jacks. If necessary, the
superstructure of
excavators must be secured against swivelling.
In the case of earthmoving machinery with centre pivot steering, the pivot joint must be
positively
locked when work is being done in that area.
When installing and dismantling counterweights, they must be placed only at the
locations
prescribed by the manufacturer.
For jacking up earthmoving machinery, lifting gear must be used in such a way as to
prevent any
slippage. Tilted positions of the lifting gear or their inclined application are
inadmissible.
Lifted earthmoving machinery must be secured by shoring up, e.g. with diagonal stacks
of planks
or squared timbers or with jacks.
Earthmoving machinery which is lifted with operating devices, must be supported
immediately
after being lifted. No work may be done under raised earthmoving machinery which
is held in
place only by the hydraulic system.

Prior to replacing the bucket scrapers of scraper vehicles or scraper-dozers, the scraper
buckets
must be set down on a non-tilting, unbreakable base.
Maintenance and repair work on scraper buckets must be done only when the
closing flap is
secured.
Prior to any maintenance and repair work, the driving motors must be
stopped.
Only maintenance or repair work which cannot be carried out with a drive is exempt
from these
requirements. It must be ensured that the drive can be stopped immediately in any
hazardous
situation prior to beginning such work.

In the case of earthmoving machinery with a combustion engine, the battery must be
disconnected
prior to any work on the electrical system or any arc welding.
When disconnecting the battery, first the negative and then the positive pole
must be
disconnected. Reconnection is done in the reverse sequence.
