• 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.
3. Before starting the engine, fix the engine securely
and make sure that there is no obstacle around the
saw chain. Then, push the top of the engine stop
switch on the right side of the rear handle and set it
to the “Run” position. After that, move the select le-
ver to the rear side of the machine body indicated
by label. The starter is started to start the engine.
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.
2. Put the machine body on the stable ground and make
sure that there is no obstacle around the saw-crossing
portion. Then, while holding the front handle with the
left hand and putting the right foot on the frame portion,
pull out the starter rope slowly.
The rope may be pulled out little by little several times.
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.
• 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.
■ 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.
■ 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.
The chain oil flow can be changed by inserting a
screwdriver in the hole on bottom of the clutch side.
Adjust according to your work conditions.
The oil tank should become nearly empty by the time
fuel is used up. Be sure to refill the oil tank every time
when refueling the saw.
■ ADJUSTING THE CARBURETOR
The carburetor on your unit has been factory adjusted,
but may require fine tuning due to a change in operat-
ing conditions.
Before adjusting the carburetor, make sure that the pro-
vided air/fuel filters are clean and fresh and the fuel prop-
erly mixed.
When adjusting, take the following steps:
Be sure to adjust the carburetor with the bar chain at-
tached.
