Note:
A new chain and bar will need readjustment after as few as 5 cuts. This is normal during
the break-in period, and the interval between future adjustments will lengthen quickly (Fig. 4).
Caution! If a chain is too loose or too tight, the bar chain and saw bearings will wear
more rapidly. Study Fig. 4 for information concerning correct cold tension (A),
correct warm tension (B), and as a guide for when saw chain needs adjustment (C).

Warning! Never cut tree limbs while standing on tree trunk.
Bucking
Bucking is cutting a fallen log into lengths. Make sure you have a good footing and stand uphill
of the log when cutting on sloping ground. If possible, the log should be supported so that the
end to be cut off is not resting on the ground. If the log is supported at both ends and you must
cut in the middle, make a downward cut halfway through the log and then make the undercut.
This will prevent the log from pinching the bar and chain. Be careful that the chain does not cut
into the ground when bucking as this causes rapid dulling of the chain. When bucking on a
slope, always stand on the uphill side.
1.
Log supported along entire length: Cut from top (overbuck), being careful to avoid cutting
into the ground (Fig. 12A).
2.
Log supported on 1 end: First, cut from bottom (underbuck) 1/3 diameter of log to avoid
splintering. Second, cut from above (overbuck) to meet first cut and avoid pinching (Fig.
12B).
3.
Log supported on both ends: First, overbuck 1/3 diameter of log to avoid splintering.
Second, underbuck to meet first cut and avoid pinching (Fig. 12C).
Note:
The best way to hold a log while bucking is to use a sawhorse. When this is not possible,
the log should be raised and supported by the limb stumps or by using supporting logs. Be
sure the log being cut is securely supported.
Bucking using a sawhorse
For personal safety and ease of cutting, the correct
position for vertical bucking is essential (Fig. 13).
Vertical cutting:
A.
Hold the saw firmly with both hands and keep
the saw to the right of your body while cutting.
B.
Keep the left arm as straight as possible.
C.
Keep weight on both feet.
Caution! While the saw is cutting, be sure
the chain and bar are being properly
lubricated.

Guide bar/saw chain installation
To install guide bar & saw chain:
1. Place power unit on flat surface.
2. To remove the side cover (A), turn the
knob (B) counter-clockwise.
(Fig. 3A).
3. Slide the bar on to the saw, and
place the chain correctly on the
sprocket wheel (Fig. 3B).
4. Spread the chain out with the cutting
edges (E) of the chain pointing in the
direction of rotating (Fig. 3C).
5. Place the side cover back in its place
and turn the knob (B) clockwise.
6. Turn the tension ring (C)untill the
chain tension is correct (Fig. 3D + 4).
7. After running the chain saw for 1
hour, check the chain tension again
and adjust when necessary.
Saw chain tension adjustment
Proper tension of the saw chain is
extremely important and must be
checked before starting, as well as
during, any cutting operation. Taking
the time to make needed
adjustments to the saw chain will
result in improved cutting
performance, prolonged chain life
and safety.
