The use of biological hydraulic oil is admissible under the following circumstances:
■
Only biological hydraulic oil based on special synthetic saturated complex esters may be used.
The products used and recommended by Wacker Neuson are shown in the overview of lubricant
details (see page 131 sqq.). Other oils used must correspond to the specifications of the oil above
mentioned. The neutralisation value (oil acid) may not exceed 2.
■
Hydraulic oil replacement (biological hydraulic oil replaces mineral oil; mineral oil replaces biological
hydraulic oil) may only be performed in accordance with special instructions. You can request for
these instructions at Wacker Neuson Customer service. All filters in the oil circuit are to be replaced
50 operating hours after oil replacement. After that, the filter change intervals given in this instructions
apply again.
■
Used biological oil must be disposed at a reliable place of disposal, just like mineral oil.
5.00.04 Coolant conditioning
For liquid-cooled diesel engines, special care must be taken for the conditioning and the inspection of
the coolant; otherwise, corrosion, cavitation and freezing can cause damage on the diesel engine. The
conditioning of the coolant is performed by adding a cooling system protection agent to the coolant.
The cooling system requires constant monitoring. Apart from the control of the coolant level, this also
implies the verification of the concentration of the cooling system protection agent.
The concentration of the cooling system protection agent can be checked with commercially available test
devices (e.g. gefo glycomat ®).
The concentration of the cooling system protection agent in the coolant should not exceed or fall
short of the following values:
Cooling system protection
agent
Water
max. 45 Vol. % 55 %
min. 35 Vol. % 65 %
The products used and recommended by Wacker Neuson are shown in the chapter lubricant details
(see page 128 sqq.) (without nitrite, amine and phosphate). The factory filled coolant blend consists of
40 parts cooling system protective liquid and 60 parts water. This guarantees freezing protection up to
-25 °C (-13 °F). The cooling system protective agent can be purchased from Wacker Neuson customer
service.
5.00.05 Fuel
MARGIN
Diesel fuel
Use only the diesel fuel commercially available which contains a sulphur
content below 15 mg/kg (15 ppm). The engine oil replacement intervals
specified here apply only for diesel fuel.
Approved diesel fuel specifications are:
■
EN 590
■
ASTM D 975-10 Grade-No. 1-D S15 and 2-D S15
In case other fuels are used that do not comply with the afore mentioned requirements, we do not accept
any guarantee.
The certification measurements to measure the compliance with statutory emission limits are carried out
using the test fuels specified by law. These fuels comply with the diesel fuels specified in this instruction
manual according to EN 590 and ASTM D 975. For all other fuels specified in this operating manual we
cannot guarantee any emission value.
