8.5 Switching off the engine (Figs. 1 and 2)
•
  Before you switch off the generator, allow it to run 
briefly with no electrical equipment connected so that it 
can cool down.
•
 Move the ON/OFF switch (Item 7) to the "O" Off 
position.
•
  Close the stop cock (Item 3).
8.6 Hour meter (Figs. 2a, 2b and 2c)
The hour meter (11) shows the actual running time of 
the generator in hours (h) and helps you to maintain 
your generator at proper service intervals (see 9.6  
Maintenance schedule).
9. Cleaning, maintenance, storage,
transport and ordering of spare parts
Switch off the motor and pull the spark plug boot
from the spark plug before doing any cleaning and
maintenance work on the equipment.
Important: Switch off the  generator immediately and 
contact your service station:
•
  In the event of unusual vibrations or noise.
•
  If the engine appears to be overloaded or misfires.
9.1 Cleaning
•
 Keep all safety  generators, air vents and the motor 
housing free of dirt and dust as far as possible.
Wipe the generator with a clean cloth or blow it with 
compressed air at low pressure.
•
 We recommend that you clean the generator 
immediately each time you have finished using it.
•
 Clean the generator regularly with a moist cloth and 
some soft soap. Do not use cleaning agents or solvents; 
these could attack the plastic parts of the equipment. 
Ensure that no water can seep into the  generator.
9.2 Changing the oil and checking the oil level
(before using the  generator) (Figs. 6, 7, 8, 9)
The motor oil is best changed when the motor is at
working temperature. Pease also read the service 
information.
•
  Keep a suitable, leak-tight receptacle within reach 
when performing an oil change.
•
  Remove the engine cover (Item 5). (only for SIG 3050)
•
  Open the oil filler screw (Item F) and connect the drain 
pipe and oil jug (Item 19,20).
•
  Drain the used oil into a suitable receptacle by
tilting the generator.
•
  Unscrew the drain pipe (Item 20).
•
 Add new engine oil until the top fill mark on the oil 
dipstick (Item D) is reached.
Important: Do not screw in the oil dipstick to check the 
oil level – only insert it as far as the thread.
•
 Use the motor oil 10W-30 or 10W-40 for general, 
normal use. The motor oil 5W-30 is recommended for 
low-Temperature environment. ( -20 degree to 0 degree)
•
  Dispose of the used oil properly by taking it to a
collection point. Most filling stations, repair garages, and 
recycling centers will accept used oil free of charge. Do 
not add antifreeze or transmission fluid to the used oil. 
Keep used oil out of the reach of children and away from
sources of ignition.
9.3 Automatic oil cut-out (Fig. 2)
•
  The engine will not start if it does not have enough oil.
•
  If the engine is low on oil while it is running, the oil 
warning indicator (Item 15) will light up red and the 
engine will stall. The oil indicator goes out when the 
engine has come to a complete stop.
•
  The engine oil must be topped up before the engine can 
be started again.
