6.When engine has ignited, first push in the choke knob to “START” position and then pull the starter again to start the engine.
7.Allow the engine to warm up with the throttle lever pulled slightly.
At once pulling throttle lever out, the choke knob is automatically returned to the “RUN” position.
Keep clear of the saw chain as it will start rotatIng upon starting of engine.
■CHECKING THE OIL SUPPLY
Make sure to set up the bar and the chain when checking the oil supply.
If not, the rotating parts may be exposed. It is very dangerous.
After starting the engine, run the chain at medium speed and see if chain oil is scattered off as shown in the fig- ure.

CHOKE START RUN
Note: When restarting immediately after stopping the engine, set the Choke knob in “START” position (choke open and throttle le- ver in the starting position).
Note: Once the choke knob has been pulled out, it will not return to “RUN” position even if you press down on it with your finger. When you wish to return the choke knob to “RUN” position, pull out the throttle lever instead.
5.While holding the saw unit securely on the ground, pull the starter rope vigorously.
Do not start the engine while the chain saw hangs in one hand. The saw chain may touch your body. This in very dangerous.
The chain oil flow can be changed by inserting a screw- driver in the hole on bottom of the clutch side. Adjust according to your work conditions.
