OPERATION
6. If the engine has started, while listening to explosion sounds, return the choke lever slowly
to full-open position. Be sure to perform a warm-up run for the period 3 to 5 minutes at low
speed, while paying careful attention to gasoline leakage or abnormal sound.
7. If it is difficult to start the engine by repeatedly pulling the starter rope, pull off the spark
plug and check the sparking performance. If the plug is wet due to excessive fuel intake or
soiled, replace the coil or clean sufficiently to its internals. With the ignition plug removed,
pull the recoil starter handle 2-3 times to discharge excessive blended gas.
2.6 Cutting
1. Before the saw is placed into operation, run the engine for several minutes. Check for fuel
leaks, and noises that would associate with a loose blade guard covers.
2. Rotate the throttle lever to
“

”
position.
3. To begin sawing, lower the rotating blade allowing it to cut to the present depth.
4. When blade has reached full cutting depth, slowly walk behind the saw at a rate that will
allow the engine to operate without losing optimum RPM.
5. When the end of the cut has been reached, raise the blade out of the cut by pulling back
on the handlebars (using a downward pressure) until the raise/lower rod drops into its slot
with the blade in the raised position.
6. If cutting is complete, shut the saw down using the following
