6.3 Air cleaner – inspecting the service indicator
Set the engine to full rpms for a short period of time. If the bellows is
drawn together during this time and the green field „1“ is covered, then
the air cleaner system is due for maintenance. Check the rubber
bellows repeatedly per day when working in dusty environments.
6.4 Starting the engine
∗
Only start with the engine starting procedure once a sufficiently stable
position is assured.
∗
Move throttle lever to start position.
∗
Slowly pull out starter rope until the engine’s compression resistance
can be felt.
∗
At this point let starter rope slowly return into starter housing.
∗
Now start the engine. Pull out the rope (evenly, not by jerks as is usual
with gasoline engines) and turn the engine with ever increasing speed.
Use complete length of starter rope.
