5 Maintenance
Stationary fuel pumps
General
Only refuel from stationary fuel pumps. Fuel from barrels or cans is usually dirty.
Even the smallest particles of dirt can cause
• Increased engine wear
• Malfunctions in the fuel system and
• Reduced effectiveness of the fuel filters
Refuelling from barrels
If refuelling from barrels cannot be avoided, note the following points:
• Barrels must neither be rolled nor tilted before refuelling
• Protect the suction pipe opening of the barrel pump with a fine-mesh screen
• Immerse it down to a max. 15 cm above the bottom of the barrel
• Only fill the tank using refuelling aids (funnels or filler pipes) with integral microfilter
• Keep all refuelling containers clean at all times
Bleeding the fuel system
If the fuel tank has been run empty, or after having performed maintenance
on the fuel system (filter replacement, water separator cleaned, etc.), the fuel
system bleeds itself automatically when starting the engine!
Checking/cleaning the water separator
The water separator is located at the front below the machine frame
Drain the condensation water every 50 o/h
☞Proceed as follows:
• Stop the engine
• Apply the parking brake
• Switch off ignition and remove the ignition key
• Place a container to collect the fuel
• Remove the protective underbody panel (option)
• Close stop cock A on the water separator
• Remove sight glass B
• Drain the water and carefully clean the sight glass
• Check the sealing ring for damage and replace it if necessary
• Install sight glass B
• Open stop cock A on the water separator
• Start the diesel engine and check the water separator for leaks
• Install the protective underbody panel (option)
Use a suitable container to collect the fuel as it drains and dispose of it in an
environmentally friendly manner!
