MAINTENANCE
WB140-2N, WB150-2N 3-29
DRAINING WATER SEPARATOR
This operation serves to drain the condensation and must be done with a
full tank, in order to prevent air from entering the fuel supply system.
Condensation must be drained at the end of work, before the engine has
completely cooled down, in order to prevent freezing if the temperature
gets very low.
The water separator can be reached after opening the engine hood. “ENGINE HOOD” on page 2-25.
Condensation is drained by loosening plug (1) and waiting until only clear diesel fuel flows out. (Use a 13 mm wrench).
MAINTENANCE EVERY 10 HOURS OF OPERATION
LUBRICATING JOINTS (GREASE FITTINGS)
This maintenance operation must be done with front bucket resting on the ground, and backhoe equipment completely
extended and resting on the ground, as indicated in the graphic.
Use the prescribed grease pump/grease. (See “FUEL, COOLANT, AND LUBRICANTS” on page 3-7 and See “LUBRICA-
TION DIAGRAMS” on page 3-12).
★ As a general rule, it is important to consider that each cylinder is provided with two grease fittings positioned on the cou-
plings and that each pin serving as fulcrum point for movement is provided with at least one grease fitting.
• The fuel is flammable; do not use exposed flames and do
not smoke while draining the water separator.
• If some fuel is spilled, wipe it up immediately.
• Clean the grease fittings before attaching the grease pump.
• After lubrication, remove all the contaminated grease that may have spread out of the fittings.
• If the machine is used in difficult conditions, perform these operations more frequently than usual.
