A standard saw unit package contains the items as
shown. (SE1)
Open the box and install the guide bar and the saw
chain to the power unit as follows.
The saw chain has very sharp edges. Use thick,
protective gloves to avoid injury.
1. Loosen a nut and remove the chain cover.
2. Mount the guide bar and fit the saw chain
around the bar and the drive sprocket. Pay
attention to the correct direction of the saw
chain. (SE2)
3. Fit the chain tensioner nut into the lower hole of
the guide bar, then install the chain cover, and
fasten the mounting nut to finger tightness.
(SE3)
When installing the chain cover, be sure to fit the
hook completely at the rear end of the cover. (SE4)
4. While holding up the tip of the bar, adjust the
chain tension by turning the tensioner screw until
the tie straps just touch the bottom side of the
bar rail. (SE5)
5. Keep holding the guide bar up, tighten the
mounting nut firmly with the attached socket
wrench.
6. Rotate the saw chain by hand, wearing a
protective glove, to see if it turns smoothly
without noticeable gap between the tie straps
and the guide bar.
A new chain will expand its length in the beginning
of use. Check and readjust the tension frequently
as a loose chain can easily derail or cause rapid
wear of itself and the guide bar.
