Working on the engine
General information – Concerning your safety
Before starting towing operations make sure that the fastening
means are able to withstand the load and are fastened at the
points provided for this purpose.
Before removing the towing facility apply appropriate measures to
secure the machine against unintended rolling.
Adhere to the specified operating, maintenance and repair meas-
ures.
The machine must only be serviced by qualified personnel author-
ised by the operating company.
Keep unauthorised persons away from the machine.
Perform maintenance work only with the engine shut down.
Make sure that the engine cannot be accidentally started during
maintenance work.
Relieve hydraulic pressures before working on hydraulic lines.
Hydraulic oil escaping under pressure can penetrate the skin and
cause severe injury. Immediately call for medical advice when
injured by hydraulic oil.
Do not step in front of or behind the machine when performing
adjustment work in the hydraulic system.
Do not change the setting of pressure relief valves.
Drain the hydraulic oil at operating temperature – danger of
scalding!
Any hydraulic oil must be collected and disposed of in an environ-
mentally friendly way.
Always collect and dispose of hydraulic oils separately.
Do not start the engine after draining the hydraulic oil. Once all
work is completed (with the system still depressurized!) check all
connections and fittings for leaks.
Hydraulic hoses must be visually inspected at regular intervals.
Do not mix up hoses by mistake.
Only genuine BOMAG replacement hydraulic hoses ensure that
the correct hose type (pressure range) is used at the right location.
Do not work on the fuel system while the engine is running -
danger to life due to high pressures!
