OPERATION
Switching off
☛
ATTENTION! Never switch off the engine with the automatic decompression (2) as this inevitably results
in damage to the valve drive and decompression mechanism.
1. Move the throttle control lever (8) to the stop.
2. When the engine is at a standstill, turn the ignition key (22) to the Stop position and pull out, control lamp
goes off.
Compaction without extension plates
If the vibration plates is used without extension plates, screw set of protective screws (8 pes) No. 0067519 into
the threaded boreholes situated in the lower mass, in order to avoid threads from being damaged.
Emergency start by hand
An automatic decompression (2) is provided to facilitate starting. It ensures that there is only a little compres-
sion pressure during the first few revolutions of the crankshaft. After several revolutions it automatically switch-
es over to the full compression pressure.
1. Turn the throttle control lever (8) to the full load position.
2. Following the direction of long arrow, turn the decompression lever until the stop position. At this point au-
tomatic decompression lever engages with an audible click, and the engine is ready to start.
3. Insert crank (24) into the bushing.
4. After having engaged the automatic decompression system to the stop position, the engine will require five
full turns of the crank until the engine regains its compression and fires up. If for any reason less than five
turns are required for the starting procedure, turn the decompression lever back in the direction of the short
dashed arrow. Each audible „click“ of the mechanism is equivalent to one turn less with the crank.
5. Stand beside the engine (feet slightly apart), viewing in the forward direction.
6. Place one hand on the machine an crank with the other hand.
☛
ATTENTION! Keep a firm hold of the crank while cranking in order to avoid the risk of sudden slip-
page.
7. Turn crank slowly at first until crank engages and then increase cranking speed.
8. As soon as the engine is running, remove crank (24).
9. Throttle control lever (8) in idling position; allow engine to warm up at idling speed for 2 - 3 minutes.
