•When this unit is shipped from the
factory, the brake is on. Release
the brake before installing the
guide bar and saw chain. You
cannot remove the chain cover
unless you release the brake. (F2)

Be sure to keep the tension of the saw
chain appropriate at all times. Since a
new chain will stretch particularly after
first using it, check and readjust the
tension frequently. If the chain is too
slack, it could come off; if the chain is
too tight, it could cause rapid wear of
the guide bar, saw chain, clutch, etc.
1. Remove the guide bar mounting nuts
and remove the chain cover.
Dispose of the cushioning material
(cardboard) between the chain cover
and the main body.
2. After setting the guide bar to the
main body, place the saw chain on
the sprockets in the proper direction
and mount the saw chain in the
groove of the guide bar.
3. After inserting the chain tension
adjusting nut into the round hole of
the guide bar, install the chain bar
onto the main body and temporarily
tighten the guide bar mounting nuts.

锯链的张力必须始终保持在适当的状态下。
特别是新锯链在开始使用后链长延伸较大，
必须频繁地进行调整。
松动的链条在使用中容易脱轨。与之相反，
链条过度张紧会导致导板、锯链及离合器
的过早磨损。
1. 拆下主体上的导板安装螺母，然后拆卸
链罩。链罩与主体间的缓冲材料（瓦楞
纸）不再需要，请将其扔掉。
2. 将导板安放到主体上后，将链轮以正确
的朝向安装到链轮上，并嵌入导板的凹
槽内。
3. 将链条张紧器螺母装入导板上的圆孔内，
然后将链罩安装到主体上，暂时拧紧导
