1. Ignition system (ignition module, 
flywheel)
The ignition system with higher spark energy 
that will be installed as standard in the TS 800 will 
also be used in the TS 700 in the future.
1.1 Ignition module
The new ignition module can easily be differentiated 
from the previous version through the embossed 
identification (see diagram).1.2 Flywheel
The new flywheel 4224 400 1201 has a second 
magnet group and can easily be identified through 
the following features:
.Two opposing pole pairs (1)
.Integrally moulded part number (2)
.Additional fan blades (3) Ignition module

1.3 Spare parts / service notes
The new ignition system will not be introduced in all 
versions of the TS 700 at the same time. Great care 
must therefore be taken to establish which ignition 
system has been installed when carrying out 
repairs.
To ensure correct operation of the ignition system, 
the individual components (flywheel and ignition 
module) of the previous and new versions may only 
be installed in correct combination:
Flywheel 4224 400 1200 combined with 
ignition module 4224 400 1300
or
Flywheel 4224 400 1201 combined with 
ignition module 4224 400 1301
Tachometer (new special tool)
Only the new tachometers STIHL EDT 8 
(5910 850 1009) or STIHL EDT 7 (5910 850 1008) 
(see TI 10.2006) can be used to measure the 
engine speed in the TS 700 with new ignition 
system and in all TS 800 models.
The previous tachometers EDT 5 and EDT 6 cannot 
be used with these machines. The additional pulses 
delivered by the second magnet pole pair would 
lead to measurement errors.
The pulses for speed measurement should be 
registered via a test lead wire. For this purpose, the 
terminal of the test lead should be connected to any 
point on the ignition lead or spark plug boot.2. Tank housing (tank vent, hose, 
routing / switch)
The previous tank housing 4224 350 0804 has been 
replaced by version 4224 350 0809 in conjunction 
with the individual changes described below.
2.1 Tank vent
The tank vent (moulded hose connecting the fuel 
tank and expansion tank) has been modified. The 
connection for the tank vent on top of the new tank 
housing (near the expansion tank) has been moved 
nearer to the front.
2.2 Hose
Hose 4128 358 7600 (155 mm long) which was 
previously connected directly to the fuel tank via a 
grommet is no longer used. It has been replaced by 
a 128 mm long hose. The new hose is connected to 
the new connector 0000 988 5206 which is inserted 
in the grommet.

The new hose is available in one meter lengths for 
replacement (0000 930 2802) and must be cut to 
128 mm (5 in.) when required.
2.3 Routing / switch
The guide ribs integrally moulded onto the tank 
housing to secure the short-circuit and ground wires 
have been spaced more closely. At the same time, 
the short-circuit and ground wires (on switch 
4224 430 0500) are no longer encased in a hose, 
but now take the form of a light plastic-sheathed 
cable. The switch now has the part number 
4224 430 0501.2.4 Service notes
The tank vent 4224 350 5800 and switch 
4224 430 0500 cannot be replaced and remain 
available for repairs to the previous tank housing.
The previous and new tank vents are of different 
colors. The previous version is made of black 
material, the new version of green material.
The hose (128 mm-5 in.) with connector 
0000 988 5206 must be used as replacement for 
the hose 4128 358 7600.
The previous and new switches differ with regard to 
the color of the short-circuit and ground wires: in the 
previous switch, these wires were blue / black, in the 
new switch they are brown / blue.

4. Service note 
(adjustment of air shutter linkage)
To ensure optimum combustion, the air shutter must 
open with a delay in relation to the throttle shutter.
If the air shutter opens too soon, the mixture will be 
too lean and the engine will overheat and/or it will be 
inadequately lubricated. For this reason, the air 
shutter linkage (between throttle shutter and air 
shutter) must be carefully and precisely set. The 
adjustment procedure is therefore described again 
here (in addition to the description in the service 
manual).
The carburetor has been removed for this 
adjustment.
.Slide the upper lever (1) onto the throttle shutter 
shaft.
Note: When fitting the lever, the flat sides in the hole 
of the lever must be lined up with those on the 
throttle shaft.
.Insert and tighten down the screw (arrow) of the 
lever.
.Turn the air shutter shaft (2) counterclockwise 
until the air shutter (1) is closed..Slide the lower lever (1) onto the air shutter shaft 
(2) until the start of the knurling, but not onto the 
knurling.
.Move test flange 4224 890 1200 up against the 
carburetor so that the shoulder (1) protrudes 
into the throttle shutter hole.
The top of the throttle shutter is pressed slightly 
inwards (opened) by the shoulder on the test flange 
and the lever (2) moves into a horizontal position.
.Fit two screws M5x80 (arrows) through the test 
flange (1) and carburetor.

.Fit nuts (arrows) and screw them tight until the 
test flange rests securely against the carburetor.
.Turn the bottom lever counterclockwise until the 
linkage (1) almost rests against the upper end of 
the oblong hole (arrow) in the lever.
The lever (1) must not be in the top dead 
center position = TDC (OT).
.Close the air shutter with a blunt tool (arrow) and 
hold it shut.
.Align lever (1) in position (A), keeping the 
linkage (2) vertical.
.Press lever (1) over the knurling on the air 
shutter shaft..Insert screw (1) and tighten it down.
The air shutter lever is now secured in position.
.Tension the leg spring (1) roughly one turn 
counterclockwise and hook it into the elbow 
connector (arrow).
Function test
Both the throttle shutter (arrow) and the air shutter 
(arrow) must be horizontal in full throttle position.
The air shutter must open with a delay when the 
throttle shutter opens (when the throttle shutter is 
approx. 1/3 open).
