CARBURETTOR

Description

WARNING!

The fuel used in the chain saw has the follow- ing hazardous properties:

•The fluid and its vapour are poisonous.

•Can cause skin irritation.

•Is highly inflammable.

The drawings accompanying this description do not correspond with the carburettor on the chain saw. They show purely the principle for the design and function. The carburettor is based on three sub-systems:

Metering unit

The needles and the fuel’s control functions are located in the metering unit (A). Here the correct quantity of fuel is adjusted for the actual speed and power output.

Mixing venturi

The mixing venturi (B) houses the choke, throttle valve and diffuser jets. Here air is mixed with the fuel to give a fuel/air mixture that can be ignited by the ignition spark.

Pump unit

In the pump unit (C), fuel is pumped from the fuel tank to the metering unit. One side of the pump diaphragm is connected to the crankcase and pulses in time with the pressure changes in the crankcase. The other side of the diaphragm pumps the fuel.
