FS 87, FS 87 R

English

The carburetor comes from the factory

with a standard setting.
This setting provides an optimum fuel-air

mixture under most operating

conditions.
These power tools are equipped with

different carburetors:

Version A

–

High speed screw and low speed

screw with special head – without

slotted head.

On these machine versions it is no

longer necessary to adjust the

carburetor.
These machines have been set at the

factory to provide an optimum fuel-air

mixture in all locations and operating

conditions.

Adjusting Idle Speed
Engine stops while idling

Warm up the engine for about 3

minutes.

Turn the idle speed screw (LA)

slowly clockwise until the engine

runs smoothly – the cutting

attachment must not move.

Cutting attachment runs when engine is

idling

Turn the idle speed screw (LA)

counterclockwise until the cutting

attachment stops running and then

turn the screw about another 1/2 to

3/4 turn in the same direction.

If the working tool or cutting attachment

continues to run when the engine is

idling, have your machine checked and

repaired by your servicing dealer.

Version B

–

High speed screw and low speed

screw with slotted head.

With this carburetor it is only possible to

adjust the high speed and low speed

screws within fine limits.

Standard Setting

Shut off the engine

Mount the cutting attachment

Check the air filter and clean or

replace as necessary.

Check that the throttle cable is

properly adjusted – readjust if

necessary – see chapter on

"Adjusting the Throttle Cable".

Check the spark arresting screen

(not in all versions) and clean or

replace as necessary.
