Always lower the dozer blade / bucket to the ground and shut down
the engine before relieving the hydraulic system.
Always lower the dozer blade / tilt blade to the ground and shut
down the engine before relieving the hydraulic system.
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 wheels 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 caught and disposed of in an environ-
mentally friendly manner.
Always catch 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!
Wait until the engine has stopped, then wait approx. another 15
minutes.
Keep out of the danger zone during the initial test run.
In case of leaks return to the workshop immediately.
Drain the engine oil at operating temperature – danger of scalding!
Wipe off spilled oil, collect leaking oil and dispose of it in an envi-
ronmentally friendly way.
Store used filters and other oil contaminated materials in a sepa-
rate, specially marked container and dispose of them in an environ-
mentally friendly way.
The settings for idle speed and highest speed must not be
changed, since this would affect the exhaust gas values and cause
damage to engine and power train.
Engine and exhaust system work at high temperatures. Keep com-
bustible materials away and do not touch any hot surfaces.
