WARNING!
The operation should be completed on a
flat and stable surface, with adequate space for moving the
machine and its components.

DANGER!
Never start the motor before installing the
guide bar, chain, and sprocket cover. Without all these parts in
place, the clutch can fly off or explode, exposing the user to
potentially serious injuries.
When you first purchase your chain saw, the chain and bar will
come pre-assembled on the saw. Should you need to replace
the chain in the future, follow the steps below.
1.
Unscrew the end cover + chain tensioning knob
counterclockwise to unlock to the end and remove the
chain/sprocket end cover (Fig. 17).
2.
Remove the cutting bar and chain from the mounting
surface (Fig. 18).
3.
Remove the old chain from the bar.
4.
Lay out the new saw chain in a loop and straighten
any kinks.
THE SHARP SIDE OF THE TEETH MUST
FACE AWAY FROM YOU IN THE DIRECTION OF THE
CHAIN ROTATION INDICATED ON THE GUIDE BAR
. If the teeth face backwards,
turn the loop over (Fig. 19).
5.
Starting at the tip, mount the chain drive links into the
bar groove, leaving a loop at the back of the bar. The
chain will loosely fit until it is placed on the sprocket
(Figs. 20 & 21).
NOTE:
Make certain of the direction of the chain
. If the chain is mounted
backwards, the saw will vibrate abnormally and will
not cut.
6.
Mount the guide bar by inserting the stud bolt into the
long slot on the guide bar; arrange the chain loop on the
back of the bar to ensure the sprocket is inserted in the
loop (Fig. 22).
