1.   Tank housing, tank vent (modified valve)

2.   Air filter (fleece material)
3.   Nameplate (plastic)
4.   Chain sprocket cover/guard

1.=Tank housing, tank vent

Mushroom valve 1110 353 1600 will be installed in
tank housing 1122 350 0816 from machine
number X 35 661 524K=ft replaces the original
two-way valve 4114 353 1600 and ensures better
pressure equalization.

                                                                                      145TI016 KN

                                                     1=   Original version
                                                     2=   New version

Air enters the tank via the new valve

1110 353 1600 (see arrows) as the volume of fuel
in the tank reduces. However, air cannot flow from

the inside outwards. Pressure can therefore build
up in the tank while the engine is stopped if the
fuel is heated by sunlight or other influences.

:DUQLQJ
Always open the fuel filler cap slowly so that any
                                                                                     145TI017 KN

excess pressure that has built up is released

gradually and fuel does not escape unexpectedly.

1) Only modified version of part is available from factory
2) Part is already installed in saws from machine numbers X 34 687 772 to X 35 661 523
3) Original version of part remains available for other models

4) New version of part is already in inventory

2.=HD air filter
The original HD air filter 0000 120 1650, which
needs to be impregnated with oil, will be replaced
by the new version 0000 120 1652 from machine

number X 36 262 047.
A fleece filter material is used in the new HD filter.
This material is designed to provide excellent

filtering efficiency without oil.

Filters with this fleece must not be
impregnated with oil. See also TI 43.96
)Technical Information 08.97  -  Page 3

3.=Nameplates

The original riveted aluminium nameplates will be
replaced by clip-in plastic nameplates from
machine number X 33 459 523K=qhe new plastic
nameplate is pushed into the carburetor box cover
and held in position by two retaining lugs. The two
holes in the shroud are countersunk for this
purpose.

Service note
Plastic nameplates cannot be fitted in the original
version of the shroud because it does not have

countersunk mounting holes. For this reason the

aluminium nameplates and round head rivets
remain available as replacements.

6.=Service note =066 cylinder gasket

In order to reduce the load on the cylinder base,

cylinder gasket E1F=NNOO=MOV=OPMN=must be
installed with the raised side facing the crankcase
E2F.

                                                                                                      1
The gasket may be used once only. Always install
a new gasket after disassembling the cylinder.                                                        2
