10. Commissioning
m ATTENTION!
Read through the safety instructions carefully.
10.1 Preparation
Place the machine upright on a firm, level surface to
ensure proper lubrication of the engine (10).
Check before operation
• Check all sides of the engine for oil or fuel leaks.
• Check the engine oil level.
• Check the fuel level – the fuel tank should be at
least half-full.
• Check the condition of the air filter.
• Check the condition of the fuel lines.
• Look for signs of damage.
• Check that all protective covers are in place and all
screws, nuts and pins are tightened.
• The firm seating of the external screw connections.
• Check whether the machine is positioned of solid,
level and secure ground in order to prevent tipping
over. Danger of injury and tipping!
• Check the location. Do not start the machine on
a hard surface such as asphalt or concrete. Avoid
set-up locations with depressions or holes (such as
gullies for example). There is a risk of slipping on
smooth, wet surfaces!
10.2 On/Off switch (16) (Fig. 11)
The ON/OFF switch (16) activates or deactivates the
ignition system. The ON/OFF switch (16) must be in
the ON position for the engine (10) to run.
The engine (10) stops when the ON/OFF switch (16)
is moved to the OFF position.
10.3 Throttle (6) (Fig. 1, 6, 14)
The throttle (6) controls the speed of the engine (10).
If the lever is moved in the directions shown, the en-
gine (10) runs faster or slower.
Fast =
Slow / Idle =
Note:
The machine is designed for a speed of 4,000 rpm.
At optimal speed, the foot beats at a rate of 680 beats
per minute. An increase of the throttle speed above
the speed set at the factory does not increase the
number of beats and can damage the machine.
m ATTENTION!
When starting the engine (10), only open the choke
lever (7) when the throttle (6) is idle. Otherwise, the
machine may actuate.
Slowly start up the machine from the idle position to
the full throttle position.
10.4 Starting the engine (10) (Fig. 11 - 14)
10.4.1 Cold start
1. Set the fuel valve on the fuel tank (19) to ON.
2. Set the fuel valve on the engine (9) to the right to
open.
3. Close the choke lever (7) and slide it to the left.
4. Open the throttle (6) slightly by moving it a little
to the left.
5. Turn the on/off switch (16) to ON.
6. Gently pull on the pull starter (11) until resistance
is felt and let it wind back in.
7. Pull strongly on the pull starter (11) and let it wind
back in slowly. Do not let the pull starter (11) snap
back. If necessary, pull the pull starter (11) several
times until the engine (10) starts.
8. Let the engine (10) warm up for a few seconds.
9. Set the throttle (6) to idle.
10. Set the choke lever (7) slowly to the right as soon
as the engine (10) is running.
11. Push the throttle (6) to the left to operate.
12. The machine starts to work.
10.4.2 Warm start (Fig. 11-14)
1. Set the fuel valve on the fuel tank (19) to ON.
2. Set the fuel valve on the engine (9) to the right to
open.
3. Open the choke lever (7) and push it to the right.
4. Push the throttle (6) to the right in idle position.
5. Turn the on/off switch (16) to ON.
6. Pull strongly on the pull starter (11) and let it wind
back in slowly. Do not let the pull starter (11) snap
back. If necessary, pull the pull starter (11) several
times until the engine (10) starts.
7. The engine (10) starts.
8. Push the throttle (6) to the left to operate.
9. The machine starts to work.
10.5 Switching off the engine (10) (Fig. 13, 14)
m Attention!
If you need to stop the engine (10) in an emergency,
turn the on/off switch (16) to the OFF position.
Use the following procedure under normal condi-
tions:
1. Push the throttle (6) to the right in idle position.
2. Turn the on/off switch (16) to OFF.
3. Set the fuel valve on the fuel tank (19) to OFF to
close.
4. Set the fuel valve on the engine (9) to the left to
close.
CAUTION!
Do not adjust the choke lever (7) to stop the engine
(10). Misfiring or engine damage may occur.
