Adjusting The Carburetor; Maintenance - Makita EK7650HX1 Originalbetriebsanleitung

Adjusting the carburetor

NOTE: This engine is equipped with an electronic ignition
to limit the speed. The carburetor also has a fixed jet which
cannot be adjusted.
At the factory the idling speed has been set to
approx. 2,600 min , but the running-in process of a new
-1
engine may require slight readjustment of the idling speed.
Adjusting screw
Set the idling speed with a screwdriver (width of blade: 4 mm).
A screwdriver with a molded-on lug, supplied as an optional
accessory, is useful for the adjustment.
4. Idling adjustment
CAUTION: Carburetor adjustment may only be done by a
specialist MAKITA service center!
Do not undertake any adjustments to adjusting screws (H)
and (L) without a tachometer! Incorrect adjustment can lead
to engine damage!
A tachometer is needed for adjustments to adjusting screws
(H) and (L), because if the engine runs over its maximum
rated speed, it can overheat and run out of lubricant. This
can damage the engine!
Only adjusting screw (T) can be manipulated by the user. If
the cutting disc moves in idle (i.e. without the throttle being
pressed), it is imperative to correct the idle speed!
Idle speed adjustment must only be undertaken when the
engine is warm, with a clean air filter.
Use a screwdriver (4 mm blade) for idle adjustments.

MAINTENANCE

CAUTION:
• Before doing any work on the Power Cutter stop the
engine and let it cool down, remove the cutting disc,
pull the plug cap off the spark plug and wear protective
gloves!
Carrying out maintenance directly after stopping the engine or
with the plug cap on the spark plug may cause burns from hot
engine or injury from inadvertent start up.
• Start the Power Cutter only after complete assembly and
inspection.
• Never use gasoline, benzine, thinner, alcohol or the like.
Discoloration, deformation or cracks may result.
NOTE:
• Wipe off dirt from the Power Cutter and then select a clean
workplace to carry out maintenance.
