RUNNING

warning

The saw chain should not move at idle, otherwise serious personal injury may result.

If saw chain moves adjust carburetor according to “Carburetor Adjustment” instructions in this manual, or see your dealer.

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. See

"Adjusting Chain Tension."

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.
