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.

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.
376TI009 KN
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. 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 It has been replaced by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.

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).
