Adjusting The Carburetor; Working In Winter - Solo 694 Instructions D'emploi

Adjusting the carburetor

E
Important information:
The carburetor of this tool is fitted with limiter caps which
restrict the range of adjustment and prevents over-rich mixture
settings. This ensures providing good engine power and
efficient fuel consumption. Before installing the limiter caps,
the manufacturer performs the „Basic Setting" procedure.
Carburetor adjustment is necessary for optimum
engine performance, for safer and more economical
operation. The engine should be warm, the air filter
clean, and the chain properly tensioned. Have
carburetor adjustment done by an authorised SOLO
service centre.
The carburetor is factory-adjusted for the air pressure at sea
level. At other elevations or under other conditions of
weather, temperature, or humidity, or when breaking in a
new engine, it may be necessary to make slight adjustments
to the carburetor.
You will need a tachometer (1, part No. 0080516) for
optimum adjustment.
Do not go below the specified basic setting of the
main nozzle (H). Doing so may cause engine damage
due to overheating and insufficient lubrication!
Use the supplied carburetor screwdriver (2) for carburetor
adjustment. It has a moulded-on projection that aids in
adjusting.
Before undertaking the adjustment, run the engine for 3-
5 minutes to warm it up, but not at high speed!
For proper adjustment, proceed as follows:
1. Basic setting (engine off)
Start engine and warm up.
2. Set idle
3. Check top speed
4. Check acceleration
5. Check idle speed
Repeat steps 2-5 until you get the right idle speed, good
acceleration and maximum permissible
1. Basic setting
Before initial operation make sure that the adjusting
screws (H and L) have not been set in all the way. Limiter
caps do not protect the engine from leaning.
Turn the two adjusting screw (H ) counter-clockwise as
far as it will go.
2. Set idle
Set the idle speed per the technical specifications.
Turning the adjusting screw (T) in (clockwise) increases
the idle speed. Turning it out (counter-clockwise) lowers
the idle speed. In no case should the chain move.

3. Check top speed
The top speed in the governor can be clearly heard
from the ignition misses. Important: To prevent
engine damage, never go more than a 1/4 turn
in clockwise with adjusting screw (H). Note:
Since there is an electronic speed governor (limiter)
at 13,500 rpm that cuts off the ignition current, the
top speed cannot be read from the tachometer.
4. Check acceleration
When the throttle is pressed, the engine should go
smoothly from idle to high speed. If this is too slow,
turn the adjusting screw (L) in small (max. 1/8 turns)
increments counter-clockwise as far as it will go.
5. Check idle speed
Check the idle speed after setting the top speed (the
chain must not move).
Repeat the adjustment procedure starting at Step 2,
until the engine runs with the correct idle speed,
good acceleration, and top speed.

Working in winter

G
In order to prevent carburetor icing in winter, warm air can
be led from the cylinder to the carburetor.
- Use the universal wrench to turn the button (G/1)
completely to the right.
- Now the carburetor heating is actuated.
If the temperature is above 0
must be switched off.
Not following this instruction may result in damage
at the cylinder and piston.
