Safety instructions on using
BIO OIL
Danger
•
Do not touch any parts such as engine block, cooling system and exhaust system during
operation and for some time after. Allow the engine to cool down. There is a risk of burns!
•
Hydraulic oil issuing under high pressure can penetrate the skin and cause severe injuries.
Therefore, even with the smallest wounds, consult a doctor since otherwise severe infections can
arise! There is a risk of burns!
Warning
•
Work on the hydraulic system of the vehicle may be done only by persons with special knowledge
and experience in hydraulics.
•
Regularly check all pipes, hoses and screw connections for leaks and external visible damage.
Immediately rectify damage and leaks. Oil squirting out can cause injuries and fires. Observe the
recommended replacement intervals for hydraulic pipes. With normal requirements 6 years, with
increased requirements on safety 2 years!
•
Do not change over hydraulic pipes! Fittings and the length and quality of the hose line must
comply with the requirements.
Environmental danger
•
Ensure safe and environment-conserving disposal of operating and auxiliary materials. Take up
escaping or spilled operating materials in suitable containers and dispose of them in an environ-
mentally friendly manner.
Attention
•
Use only the BIO hydraulic fluids approved by the Hako GmbH, see Engine/vehicle fluids and
lubricants. Use of another not recommended product must be agreed with Hako without fail. In
addition, a written guarantee declaration must be obtained from the supplier. This guarantee
applies for the case that damage to hydraulic units occurs that is demonstrably attributable to the
hydraulic fluid.
•
Use only BIO oil of the same grade for topping up and oil changing. Clear information about the
momentary oil grade used must be placed close to the filler cap! Mixing two BIO oil grades can
impair the properties of one grade. Make sure that when the BIO oil is changed, the remaining
residual volume of the original hydraulic fluid in the hydraulic system does not exceed 8 %
(manufacturer's data).
•
Do not top up with mineral oil. The mineral oil content should not exceed 2 % by weight to avoid
foaming problems and not to impair the biological degradability of the BIO oil.
•
When running the vehicle with biodegradable oil, the same oil and filter replacement intervals
apply as for mineral oil, see Engine/vehicle fluids and lubricants. The condensed water in the
hydraulic oil tank must be drained off before the cold season. The water content should not
exceed 0.1 % by weight.
•
All information about environmental protection in this operating manual also applies when BIO oils
are used.
•
If additional hydraulic devices are attached and operated, then operate these with the same BIO
oil grades, so that mixing in the hydraulic system is avoided.
•
In subsequent oil changing from mineral to BIO oil, the hydraulic units must be scavenged
completely.
