Note
Use of hydraulic oil that does not meet the required grade or temperature
range may cause poor operation, reduced efficiency and/or damage to
hydraulic components.
Combilift trucks are supplied with ISO Grade 46 hydraulic fluid unless
otherwise stated. Refer to the decal on the hydraulic tank. Please check if
the hydraulic fluid is suitable for the trucks operating temperature range.
Note
Clean and dry the area around all components concerned thoroughly.
Observe safety regulations when handling oils and avoid skin contact.
Do not pour fluids into the ground, down a drain or into a stream, pond or
lake. Observe relevant environmental protection regulations when disposing
of used oil and filters.
6.13 Hydraulic Oil System
Hydraulic Oil
The hydraulic oil must be changed at regular intervals in accordance with the
maintenance schedule.
The hydraulic oil used in the trucks hydraulic system must conform to
ISO 3448
viscosity classification grade and include additives for improved:
Viscosity index
Wear prevention
Corrosion protection
Stability against oxidation
Deaerating and foam suppressing
Compatibility with seals and gaskets
Low pour point
The oil must also have the correct temperature range for the operating temperature of
the truck. If the operating temperature is outside the range of the standard grade 46
oil, the standard oil should be replaced with the appropriate grade of oil.
The correct grade of oil for the relevant operating temperature range can be
determined using the following table:
Caution
Switch off the engine before working on the hydraulic system.
Wait until the engine and hydraulic tank are cool enough to touch before
commencing work.
