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. 
NOTICE
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.
