Carburettor adjustment

When the carburettor is being adjusted, the cutting attachment may move. Be careful not to get injured.
You may adjust the idle speed only. Contact your dealer if the carburettor needs to be adjusted for speeds other than
the idle.
When starting, idle speed adjustment screw (T) should be adjusted not to rotate the cutting attachment.

WARNING
CAUTION
Remove the cutting attachment, cutting attachment holder and
gear shaft collar. Remove the filler plug from the side of the
gearcase and press new grease into the gearcase until old
grease is pushed out. Use good quality lithium multi grease.
Fuel Filter Maintenance
Use a hooked wire to extract the fuel filter from inside the fuel
tank. Remove and replace the filter element. Before reinstalling
the filter, inspect the condition of the fuel line. If damage or dete-
rioration are noted, the unit should be removed from service until
you can consult with an authorized servicing dealer.
Make sure you do not pierce the fuel line with the end of
the hooked wire. The line is delicate and can be damaged
easily.
Every unit is test run at the factory and the carburettor is fine
tuned for maximum performance.
Before adjusting carburettor, clean or replace air filter, start en-
gine and run several minutes to bring it to operating temperature.
The engine must return to idle speed whenever the throttle lever
is released. Idle speed is adjustable, and must be set low enough
to permit the engine clutch to disengage the cutting attachment.
To adjust the carburettor proceed as follow:
1. Place the unit on the ground, then start the engine, and then
allow it to idle 2-3 minutes until warm.
2. If the attachment moves when the engine is at idle, reduce
the idle speed by turning the idle adjustment screw(T) coun-
ter-clockwise.
3. Repeat the process of accelerating to full throttle and return
to idle a few times. Check that the cutting attachment stops
moving at idle.
4. If a tachometer is available, the engine idle speed should be
final adjusted to the settings recommended in the Specifica-
tions section.
