with the currently valid safety regulations. Nevertheless, remaining
risks cannot be ruled out completely, even when using the machine

rp
for the purpose it is intended for and following all information given
in the operating instructions.
A remaining risk can also not be excluded beyond the actual

ou
danger zone of the machine. Persons remaining in this area must
pay particular attention to the machine, so that they can react
immediately in case of a possible malfunction, an incident or failure

ry
etc.
All persons remaining ion the area of the machine must be

de
informed about the dangers that arise from the operation of the
machine.

or
Regular safety inspections Have the machine inspected by an expert (capable person) as

en

allowed to operate, service or repair the machine.

Maintenance and repair work requires specific knowledge and
m

must therefore only be performed by trained specialists.

ip

Changes and conversions to the Unauthorized changes to the machine are prohibited for safety rea-
qu

machine sons.
Original parts and accessories have been specially designed for
-E

this machine.
We wish to make explicitly clear that we have not tested or
nt

approved any parts or accessories not supplied by us.

ou

The installation and/or use of such products may have an adverse

effect on the active and/or passive safety.
The manufacturer explicitly excludes any liability for damage
sc

caused by the use of non-original parts or accessories.

Di

Damage, deficiencies, misuse of Machines which are not safe to operate must be immediately taken
safety installations out of service and shall not be used, until these deficiencies have
to

been properly rectified.

Safety installations and switches must neither be removed nor
o

must they be made ineffective.

For lifting the machine attach the lifting gear only to the

de
lifting eye provided for this purpose.
Check lifting eye for damage before use. Do not use a

damaged or in any other way impaired lifting eye.
Do not lift or lower the machine jerkily.

6.1 General notes on maintenance

When performing maintenance work ensure strict compliance with

ts
the respective safety instructions and particularly the safety regula-
tions mentioned in the corresponding section of these operating

ar
and maintenance instructions.

rp
Thorough maintenance of the machine guarantees far longer safe
functioning of the machine and prolongs the lifetime of important
components. The effort needed for this work is only little compared

ou
with the problems that may arise when not observing this rule.
Always clean machine and engine thoroughly before starting
maintenance work.

ry
For maintenance work stand the machine on level ground.

de
Do not touch hot engine parts.
Generally perform maintenance work only with the engine
shut down and the spark plug socket disconnected.

or
to
ENVIRONMENT!
om
During maintenance work catch all oils and fuels and
do not let them seep into the ground or into the
sewage system. Dispose of oils and fuels environmen-
tally.
t.c

Keep used filters in a separate waste container and

dispose of environmentally.
en
m

Notes on the fuel system The lifetime of the engine mainly depends on the purity of the fuel.
ip

Keep fuel clean of any contamination and water.

qu

When choosing the storage place for fuel make sure that
spilled fuel will not harm the environment.
-E

Fresh fuel should not be stored for longer than 3 months, if no fuel
nt

stabilizer has been added.

When storing for longer than 3 months:
ou

Directly after buying fresh fuel add the correct amount of fuel
stabilizer to the fuel (follow the instructions of the manufac-
sc

turer).
Di

Notes on the performance of the On engines both combustion air and fuel injection quantities are
engine thoroughly adapted to each other and determine power, tempera-
ture level and exhaust gas quality of the engine.
to

If your engine has to work permanently in "thin air" (at higher alti-
tudes) and under full load, you should consult our customer service
o

or the customer service of the engine manufacturer.

6.2 Fuels and lubricants

Engine oil Oil viscosity

ts
Choose the oil viscosity in dependence on the ambient tempera-

ar
ture at the operating location of the engine (see diagram).
SAE10W-30 is recommended for general use under any tempera-

rp
ture. When using single purpose oil you must choose the correct
viscosity for the average temperature in the area of use.

ou
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.

ry
Temperature related lubrication oil changes can be avoided by
using multi-purpose oils. The following oil change intervals apply

de
Fig. 32 also when using multi-purpose oils.
Oil quality

or
You should preferably use oils of API-quality class SF/SG or
higher.

to
Lubrication oil change intervals
6 months or 100 operating hours
om
When changing to a higher alloyed oil quality after a
longer period of operation, it is recommended to per-
t.c

form the first oil change of the higher quality oil already
after 25 operating hours.
en
m

Fuel Quality
Use automobile gasoline (preferably unleaded fuel or fuel with a
ip

low lead content, in order to reduce the combustion residues to a

minimum).
qu

Do not use oil-gasoline mixes or contaminated gasoline. Protect

the fuel tank against dirt, dust or water.
-E

Alcohol containing gasoline

nt

If you decide on using alcohol containing gasoline (Gasohol), you

should make sure that the octane number is at least as high as for
ou

unleaded gasoline.
There are two types of "Gasohol" available: one contains ethanol
and the other one methanol. Do not use "Gasohol" with more than
sc

10% ethanol. Do not use any gasoline with admixed methanol

(methyl or methyl alcohol), which does not contain solvents or cor-
Di

rosion protection for methanol. Do not use gasoline with more than
5% methanol, even if it contains solvents and corrosion protection
agents.

 Maintenance

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 correct amount of fuel stabilizer
(BOMSAG 009 940 20) directly after you have purchased fresh fuel

ts
(follow the instructions of the manufacturer).The fuel stabilizer has
a limited shelf life. The effect diminishes over the course of time

ar
(store for max. 2 years after opening the bottle).

Fuel cannot be regenerated by using fuel satbilizer.

WARNING!

Do not use gasoline or cleansers with a low flash-point
to clean the air filter element. This could cause fire or
an explosion.

ou
ry
NOTICE!
Do not run the engine without an air filter, since this
could cause premature wear of the engine.

de
Contaminants or dirt must not enter into the intake
channel.

or
Contamination of the air filter depends mainly on the
proportion of dust in the intake air, if necessary clean

to
several times a day.
Air filters with damaged filter element or seal ring must
om
be replaced in any case. It is therefore recommended
to keep at least one air filter in stock.
The air filter must be changed after several times
t.c

cleaning, but at the latest after 1 year.

Each cleaning interval must be marked with a cross on
en

the cover of the air filter.

Cleaning does not make sense if the air filter is cov-
ered with a sooty deposit. Use a new air filter.
