As required
Fuel pre-filter - Drain fluid
Drain water and sediment from the fuel pre-filter as required. In certain geographic regions and climates, it may be
necessary to drain condensation more frequently.
Prior operation:
Park the machine on a firm, level surface. Lower the attachment to the ground. Apply the parking brake, and install
the transport service link to prevent unexpected articulation movements.
Drain fuel filter condensation
1. Open the engine hood. Locate the pre-filter on the
right-hand side of the machine.
2. Remove the connector. Open the drain valve on the
fuel pre-filter by turning counterclockwise two or three
turns. Drain the water and/or contaminants from the
pre-filter into a suitable container until clean fuel flows.
Do not allow fuel to spill on engine or ground.
3. Close the drain valve. Reconnect the electrical con-
nection. Check for leaks.
NOTE: if it is necessary to bleed the fuel system, use the
attached pump and the bleed screw at the top of the pre-
filter housing.
