Engine oil
Oil viscosity
Fig. 37
Choose the oil viscosity in dependence on the am-
bient temperature at the operating location of the
engine (see diagram).
Occasional falling short of the temperature limit
(e.g. use of SAE 15W-40 down to -15 °C (+5 °F))
may effect the cold starting ability of the engine,
but will not cause any engine damage.
Temperature related lubrication oil changes can
be avoided by using multi-purpose oils. The follow-
ing oil change intervals apply also when using mul-
ti-purpose oils.
Oil quality
You should preferably use oils of API-quality class
SF/SG or higher.
Lubrication oil change intervals
6 months or 100 operating hours
Note
i
When changing to a higher alloyed oil quality after
a longer period of operation, it is recommended to
perform the first oil change of the higher quality oil
already after 25 operating hours.
Fuel
Quality
Use automobile gasoline (preferably unleaded fuel
or fuel with a low lead content, in order to reduce
the combustion residues to a minimum).
Do not use oil-gasoline mixes or contaminated
gasoline. Protect the fuel tank against dirt, dust or
water.
Alcohol containing gasoline
If you decide on using alcohol containing gasoline
(Gasohol), you should make sure that the octane
number is at least as high as for unleaded gaso-
line.
There are two types of "Gasohol" available: one
contains ethanol and the other one methanol. Do
not use "Gasohol" with more than 10% ethanol. Do
not use any gasoline with admixed methanol (me-
thyl or methyl alcohol), which does not contain sol-
vents or corrosion protection for methanol. Do not
use gasoline with more than 5% methanol, even if
it contains solvents and corrosion protection
agents.
Fuel stabilizer
If the machine is only occasionally used (i.e. if it is
out of use for longer than 4 weeks), mix in the cor-
rect amount of fuel stabilizer (BOMSAG 009 940
20) directly after you have purchased fresh fuel
(follow the instructions of the manufacturer).
The fuel stabilizer has a limited shelf life. The ef-
fect diminishes over the course of time (store for
max. 2 years after opening the bottle).
Fuel cannot be regenerated by using fuel satbiliz-
er.
Mineral oil based hydraulic oil
The hydraulic system is operated with hydraulic oil
HV 32 (ISO) with a kinematic viscosity of 32 mm
2
/
s at 40°C (104 °F).
For topping up or for oil changes use only high-
quality hydraulic oil, type HVLP according to DIN
51524, part 3, or hydraulic oils type HV according
to ISO 6743/3. The viscosity index (VI) should be
at least 150 (observe information of manufactur-
er).
