5.2. Information about engine performance
The performance refer to standard conditions (0m sea level, +25°C
ambient temperature). For higher temperature or usage at higher sea
level it is necessary to calculate a derating of the maximum perfor-
mance.
5.3. Information about starter battery (optional)
Please consider following points:
Lead acid batteries contain sulfuric acid. If there are liquids escaping
from the battery do not touch or swallow them. Carefully dilate the acid
with water and neutralize it with soda (sodium carbonate).
Always wear protective gloves and safety goggles when working with
the starter battery.
When correctly set up, the battery will be charged via the built in dy-
namo.
If the motor is operated without a battery (ex. when using an external
battery to start up), the plus cable from loading regulator has to be
isolated against the crankcase. A shortcut could damage the dynamo
or loading regulator.
When using a car battery to jump start the engine, first disconnect the
starter battery of the motor. If the built in battery is completely drained
the car battery could load an extremely large current into the starter
battery. This seriously damages the battery, in extreme cases the bat-
tery might even explode.
Be very attentive when handling starter cables, if it comes to an elec-
trical shortcut very large currents can be transmitted. Therefore re-
member: always connect the plus(+) pole first, then the minus(-) pole.
5.4. Check-ups before every start-up
5.4.1. Engine oil
Oil is the most important resource of the motor. Only use high qua-
lity, synthetic motor oil of specification API SL/SM, for gasoline en-
gines.
Check the oil level bevor every start up! ATTENTION – when delivered
the engine is NOT supplied with oil and must not be started up under
any circumstance!!
Remove the oil dipstick
❶
and wipe it
with a clean piece of cloth. Reinsert the
clean dipstick
❶
completely, then re-
move it again. The correct oil level
❸
is
now marked by the oil film covering the
dipstick. The line has to be close to the
maximum mark
❹
. If necessary add more
oil, in order to achieve the correct oil level
❷
(lower edge of the thread in the crank-
case).
Do not add too much oil – too much oil is damaging and must be drai-
ned! Different types of oils and brands may not be mixed together!
Note the maintenance intervals of the oil change.
5.4.2. Fuel
Fill up the tank completely with fresh, lead-free premium or normal
gasoline.
Please note that gasoline usually should not be stored for longer than
3-6 months. Always use fresh gasoline. See the instructions for storage
in chapter 2.3. For further information.
5.4.3. Other check-ups
• Remove any dirt or dust, so that the engine cooling cannot
suck in any foreign matter.
Note that the motor must NOT be started up if the protective covers are
not attached properly.
• Check that the device does not have any leaks (fuel, oil, battery
acid). Fasten leaking sealing caps appropriately.
• Make sure the device is well ventilated. The exhaust gas of the
motor can be damage your personal health.
5.5. Start-up
5.5.1 Special information about initial start-up
The motor must only be started up when the device was installed fol-
lowing the rules and instructions of this manual and the engine base is
fixed properly to a stable mounting frame.
• Let the motor run on half rated rotational speed (aprox. 1.500-
1.800 min
-1
) for 1 hour after starting up for the first time.
• Turn off the engine after initial start-up and check the oil level.
• Check all screws, nuts and clamp connections after initial
start-up. Refasten if necessary.
If the engine behaves abnormally (noise, smoke) turn off the motor
immediately and solve the cause of error before putting the engine
into operation again.
To ensure a maximum life-span of the motor it is recommended not
to operate above 3.000 min
-1
in the first 50 hours of operation. Only
change the speed slowly during this 50 hours (change governor po-
sition slowely)!
5.5.2. Starting the engine
It is forbidden to start up the motor without properly assembled air
filter and muffler!
• Open the fuel cock
• Shift the choke lever to “Start”
• Move the throttle lever to full-speed (=Start)
5.5.2.1. Hand start (all versions)
• Pull the recoil-starter slowly until you feel some resistance.
Bring the recoil handle slowly back.
• Pull the recoil handle hard and fast.
• Repeat until the motor starts up.
?
5.5.2.2. Electric start (only motor version “E”)
• Turn the start key to “START”. Let go of the key as soon as the
motor starts up.
Only start up for a maximum of 10 seconds! If the engine doesn’t start,
wait one minute until trying to start-up again. This process may only
be repeated for a maximum of 3 times, then the electric starter has to
be left to cool down for at least 15 minutes. Contravening can result in
damaging the starter and/or motor. Never start into the running engine!
Generally you should not connect a load higher than 50% of the nomi-
nal load when the engine is cold.
• Observe the engine run and the colour of the exhaust gas after
starting up. The engine should run smoothly after a few se-
conds.
•
Slowely bring back the chocke lever to position
"RUN"/"BETRIEB"
5.5.3 Stopping the engine
• Let the engine run without load for about five minutes after
being used for heavy load – this way the motor can cool down.
• Bring stop-switch or main-switch to position "OFF" to turn off
the engine.
• Close the fuel cock.
When the device is not to be used for longer than two weeks, consider
the instructions in chapter 2.3.
