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 4000 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.

STOPPING

• Release throttle trigger and move ignition switch

down to “STOP” position.

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.

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.

   CAUTION

Do not operate with a loose chain.

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.
