REMOVING WATER FROM THE WATER SEPARATOR FILTER AND REPLACEMENT OF THE FILTER ELEMENT Removing water from water filter separator
Replacing the filter element
STEP 1 STEP 1
TRIM THIS EDGE
CD98A015 Water must be removed from the water separator element when the warning lamp on the instrument panel comes on.
STEP 2
CD98A054 Remove the detector. Using the filter wrench, remove the element.
STEP 2
CK98B031 Open the water separator water drain valve. Operate the pump about 7 times to remove the water from the filter and close the valve.
PH08325 Apply a fine coating of oil or grease to the new element seal. NOTE: Do not fill the new element with fuel before installing it.

STEP 3
Install the new filter. Turn the filter until the seal is in contact with the filter head and then tighten the filter an extra half turn by hand. NOTE: Do not use the filter wrench. If the filter head is tightened excessively, damage to the seal and filter can result.
STEP 4
Install the detector and bleed the system. See “Bleeding air from the fuel system”.
Removing water from the fuel tank
STEP 1
Place the upperstructure at right angles to the undercarriage. Stop the engine and remove the starter switch key.
STEP 2 STEP 3
CD98A055 Place a receptacle of a suitable capacity under the tank. Open the drain valve and allow the dirty fuel to flow out.
STEP 4
When only clean fuel is flowing out, place the drain valve in the closed position.
Filling
Before filling, make sure that the drain valve is in the closed position.
STEP 1
CD98A034 Using the starter switch key, open the right hand side panel.
CD98A008 Clean carefully around the filler cap. Slide back the filler cap opening protection and remove the filler cap by means of the starter switch key.

STEP 2
Fill the tank, making sure that neither water or dirt enters the tank. IMPORTANT: Never remove the tank filter while filling.
WARNING: Never refill the fuel tank when the engine is running. Never smoke while refilling.
IMPORTANT: In cold weather, use fuel corresponding to the ambient temperature. See “Fluids and lubricants” in the “Lubrication/Filter/Fluids” Section.Fill the fuel tank after each working day to prevent the formation of condensation.
STEP 3
Install the fuel tank cap and lock it by means of the starter switch key. IMPORTANT: Make sure that the fuel tank cap is correctly locked.

Replacing the filter element on the reservoir
Tools required
-One filter wrench
STEP 1
CD98A056 Place a receptacle of a suitable capacity under the filter, loosen the filter by means of the filter wrench and then unscrew it by hand.
STEP 3
Apply a fine coating of oil on the new filter seal.
STEP 4
Clean around the filter.

CS98A185 Clean around the cover. Remove the screws (1), the washers (2), the cover (3), and the seal (4) from the reservoir. Remove the filter (5). Install a new filter. Install the seal (4) or replace it if necessary. Install the cover and its retaining hardware. Check the level in the reservoir. Top up if necessary. See “Filling”. Re-pressurise the hydraulic reservoir. See “Pressurising the hydraulic reservoir”.
Replacing the hydraulic fluid
The replacement of hydraulic fluid consists of systematically draining the oil from the main components (reservoir, pumps, cylinders, control valves, hydraulic motors, oil cooler). We recommend that you consult your CASE Dealer.
