Ignition switch

STOP Throttle trigger

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 3800 r/min approximately.

•Confirm proper acceleration and lubrication of chain and bar.

•Give several strokes to manual oiler button to confirm extra lubrication.

•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.
