STARTING ENGINE
1. The process of run-in before driving
When you get a new engine, we might remind you that,
no matter what kind of engine, it is important to clean
inside of the engine. They will damage the engine if
the dust and scruff get into it.
Secondly, for the run-in process, we adopt traditional
methods. In other words, we carry out the cool run-in
process under the condition of rich gas. However, the
adjustment situation of the needle valve accords with
the situation of leaving factory. Turn down the needle
value until the carburetor is in full speed without stop,
and go on with 5 tanks oil during those process, you
should let the engine stop for a while before carry on
following process.
Glow plug starter
When going load milling, the curtate range of the needle
valve should not be adjusted excessively, approximately
1/4 round is best under preview work or reaching the
properly middle/low speed. However, the main needle
only need be curtailed a little. We suggest that the
temperature is no more than 90 centidegree .

starter is heavy, remove plug/pull recoil starter for 20-30
times to discharge the fuel.
