3.21 Changing work attachments, maintenance, and
repairs
The machine must only be converted by the service personnel, or maintained and
repaired by the maintenance personnel, under the guidance of a suitable person
designated by the plant operator and in accordance with the manufacturer’s
operating instructions.
 After changing the work attachments, make absolutely certain that the work
attachments have been fastened correctly.
Work on e. g.
• Braking system
• Steering system
• Hydraulic system
• Electrical system
of the machine may only be carried out by specialist staff trained in these areas.
Stability must be ensured during all types of work on the machine at all times.
 Unless expressly instructed otherwise, always switch off the engine during
maintenance work. Secure the engine against restarting. (Isolate the machine
from the power supply using the battery isolator or by removing the battery
clamps.
 Put the machine into the parking position. Uppercarriage in the driving position.
 Allow the machine to cool.
 Always depressurize the system.
 Always depressurize the hydraulic system before starting maintenance and
repair work on it. With the engine turned off, lower the loading equipment to
the ground and actuate all hydraulic operating levers until there is no more
pressure in the hydraulic system.
 Always secure the machine with wheel chocks to prevent rolling when
working on or especially under the machine.
 Keep any third parties clear of the machine’s danger zone.
 Secure the work equipment against movement by lowering it to the ground or
by implementing equivalent measures, e.g., cylinder supports, trestles.
 As long as the engine is running, the unprotected working zone must not be
entered.
 Attach the lifting gear for jacking up the machine so that it cannot slip off.
Make sure that the jacks are placed exactly vertically.
 The raised machine must be supported with suitable structures,
e.g., crosswise stacked planks, square timbers or steel trusses.
 Use a supporting structure to stabilize the machine that has been lifted with
the work equipment. Do this immediately after lifting. Work under raised
machines which are only supported by their hydraulics is forbidden.
 Shut down the engine before any maintenance and repair work. These
requirements may only be ignored in the case of maintenance or repair work
which cannot be performed without the engine/motor(s) running.
