NOTE

2.When the outside temperature is below 0°C, repeat the above warming-up operation twice or more. After the engine stops, use the product in a shorter leaving time.

WARNING

•Be sure to perform warming-up with the guide bar and the saw chain mounted.

•Keep clear of the saw chain as it will start rotatIng upon starting of engine.

•Before you start the engine, make sure the saw chain is not contacting anything.

The rope may be pulled out little by little several times.

WARNING

•When pulling out the rope, large clanging is produced. With this clanging, stop pulling out the rope at once. This sound notifies that One-push-start has been set.

•Don’t pull out the rope excessively or don’t pull it out without load by the starter only, otherwise a starter failure will occur.

NOTE

If the engine cannot be started by the above proce- dure, repeat the above operations again. If the en- gine cannot be started smoothly, it may be neces- sary to add warming-up or readjust the engine. Per- form warming-up enough and ask the distributor to readjust the engine.

■FOR SMOOTHER USE OF ONE-PUSH-START

To use One-push-start more smoothly, it is important to perform warming-up longer than ever.

1.When the outside temperature is 0° or more, perform warming-up for about 5 seconds with the throttle fully opened. And leave the product for 5 minutes or less after the engine stops. Then, use the product. With this, the engine can be started more securely.
