CHANGING THE HYDRAULIC OIL AND
CLEANING THE SUCTION STRAINER AND
FILLER STRAINER/BREATHER
MAINTENANCE AND SERVICE 14
Note:- the oil should only be changed when the engine is switched
off, the skip is at rest on the stops, the scissors lowered to the rest
position and any residual hydraulic pressure remaining in the
system has been ‘dumped’ as described under ‘Safe Working’. Wear
suitable gloves to protect the skin.
Run the engine and operate the hydraulics until the hydraulic oil is
warm, stop the engine, dump any residual pressure.
Place a suitable container below the hydraulic tank, clean the area
around the filler/breather and remove the cap. Carefully undo the
drain plug located under the tank, remove and allow the oil to collect
in the container.
Replace the drain plug, fitting a new sealing washer if required.
Undo the suction hose connection on the rear vertical face of the
tank, remove the hose from the tank and allow any oil to drain into
the container.
Remove the four nuts and washers retaining the square cover to the
face of the tank, take care not to lose the small sealing washers.
Carefully pull the cover away from the tank body taking care not to
damage the gasket between the two, pull the cover to the rear until it
clears the four studs and continue until the suction strainer located
on the back of the cover is clear of the tank.
Allow any oil to drain from the filter, carefully unscrew the strainer
and wash out in solvent. Examine the strainer for damage, if
punctured it should be replaced, as it will no longer be effective.
Refit the strainer in the reverse order replacing the gasket and four
small sealing washers if necessary. Take care not to strip the
threads on the studs when securing the cover in place. Refit the
suction hose.
Remove the three small slotted screws securing the filler/breather
body into the top of the tank, carefully lift the assembly clear of the
tank taking care not to damage the cork gaskets. Wash the filler
