CS-440

RUNNING

• When engine starts, keep idling for a few

minutes.

• Set the brake lever in the unlocked position

before starting to cut.

• Pull throttle trigger gradually and increase

revolution of the engine.

• The chain starts running when the engine

reaches 3,800 r/min approximately.

• Confirm proper acceleration and lubrication of

chain and bar.

• Do not run the engine at high speed

unnecessarily.

• Be sure that saw chain stops moving when

throttle trigger is released.

STOP

CHAIN LUBRICATION TEST

Hold the chain just above a dry surface and open
the throttle to half speed for 30 seconds.

A thin line of “thrown” oil should be seen on the dry
surface.

CAUTION

Do not operate with a loose chain.

CHECKING CHAIN TENSION

• Chain tension should be checked frequently

during work and corrected as necessary.

• Tension the chain as tight as possible, but so it

can still be pulled easily along the bar by hand.

NOTE

If engine does not stop, pull choke control knob
out fully to stop engine.

Return the unit to your authorized ECHO dealer
to check and repair stop switch before starting
the engine again.

STOPPING

• Release throttle trigger and move ignition switch

down to “STOP” position.
