ADDING HYDRAULIC OIL
Remove tank filler cap (A) and add oil. Add clean,
filtered hydraulic oil. The oil level should always be
above the suction strainer in the tank, ideally just below
the top (B) of the visual indicator. Do not over fill the
hydraulic tank as it needs room to vent air.
Replace filler cap immediately after filling.
CHANGING THE HYDRAULIC OIL
Before draining the hydraulic tank ensure
the hydraulic oil is warm NOT HOT
•
Lower the skip and the hi-lift sections to their normal
fully down positions.
•
Stop the engine and allow to cool.
•
Release any pressure from the hydraulic lines by
moving the levers back and forward several times.
•
Remove the filler cap (A) & remove the bung (C) on
the underside of the tank and drain the oil into a
suitable container (approx 30L of volume).
•
Ensure tank is free of contamination and clean if
required.
•
Replace the filter according to the maintenance
instructions.
•
Replace magnetic bung (C) in bottom of tank. Max
torque 15 Nm
It is extremely important to follow the correct oil fill
procedure to prevent internal damage to the
hydrostatic drive pump.
•
Fill the hydraulic oil tank with clean filtered HVZ 46
oil to approx level at (B).
•
Crank the engine over but do not let it start, this will allow oil to get into the filter and the
drive pump to get lubricated.
•
Repeat this procedure about 5 times.
•
Start the engine and idle for a period of five minutes. This allows the oil to fill the hoses,
oil cooler and filter.
•
Stop the engine and wait approximately one minute, recheck the oil level and fill to level
as indicated by (B ).
