Different cuts for BUCKING (Fig. D)

m

 Caution: If the saw is clamped into a log, do not pull 

it out by force. You risk losing control of the device, 
thereby resulting in injury and / or damage to the saw. 
Hold the saw, and drive a plastic or wood - wedge into 
the cut until the saw can be pulled out easily. Position 
the saw carefully and allow it to cut again. Start the 
saw if it is trapped in a trunk.

Upper section (Fig. E, Item 1) 

Position the saw at the upper end of the log. With the 
overcut apply only slight downward pressure

Sub-section (Fig. E, item 2)

Place the undercut at the bottom of the trunk, holding 
the top of the saw down against the log. Practice the 
undercut; it is just as easy to train from the top. Hold 

the saw firmly and maintain control. The saw will push 

backwards (towards you).

m

 Caution: Never hold the saw upside down for an 

undercut. In this position, you have no control over the 

device. Always execute the first cut on the compres

-

sion side of the log. The compression side of a log is 
where the pressure of the root weight is concentrated

Bucking without supports (Fig. F) 

•  When the whole length of the tree trunk is stable 

and even, start sawing from the top (No. 1).

•  Make sure you do not saw into the ground.

Trunk cutting, supported on one end (Fig. G)

•  When the tree trunk is propped up on one end, 

make the first cut (No. 1) from underneath (1/3 of 

the trunk diameter) in order to prevent splitting.

•  The second cut is made from the top (2/3 of the 

diameter) in the same line as the first cut to prevent 

the saw from becoming jammed.

Trunk cutting, supported on both ends (Fig. H)

•  When the tree trunk is propped up on both ends, 

make the first cut (No. 1) from the top (1/3 of the 

trunk diameter) in order to prevent splitting.

•  The second cut is made from underneath (2/3 of the 

diameter) in the same line as the first cut to prevent 

the saw from becoming jammed.

Limbing and Trimming 

m

 Attention: Always pay attention to, and protect 

yourself against kickback. Never let the moving chain 
at the top of the guide bar come into contact with other 
branches or objects when limbing or trimming. Such 
contact can cause serious injury.

m

 Attention: Climb the tree for pruning or trimming. 

Do not stand on ladders, platforms, etc. as you may 
lose your balance and lose control of the device.

Important Notes 

• 

Work  slowly,  and  hold  the  saw  firmly  with  both 

hands. Ensure safe standing position and balance.

•  Watch out for spring backs. Use extreme caution 

when cutting small size limbs. Pliable material may 

Undercut and felling of the tree (Fig. B-C)

•  Saw a wedge with a depth of 1/3 of the tree diam-

eter at a right-angle to the falling direction. Make 

the lower horizontal wedge cut first (Fig. B, No. 1). 

This will prevent the saw chain or the guide bar be-
coming jammed when the second wedge cut (Fig. 
B, No. 2) is made.Now remove the excised wedge.

•  Next, you can run the felling cut (Fig. B, Pos. 3) on 

the opposite side of the tree. Do this at approxi-
mately 5 cm above the centre of the notch. Make 
the dropping cut parallel to the horizontal wedge cut. 
For the dropping cut (No. 3), saw only to a depth so 
that a bridge (No. 4) (holding wood) remains which 
can act as a hinge. The bridge prevents the tree 
from turning and falling in the wrong direction. Do 
not cut through the bridge.

m

 Note: When the dropping cut is made close to the 

bridge, the tree should start falling. If it looks like the 
tree may possibly not fall in the desired direction or it 
leans back and traps the saw chain, stop the dropping 
cut and use wedges of wood. plastic or aluminium to 
open the cut and to tilt the tree into the required falling 
direction.
When the tree starts falling, remove the chainsaw 
from the cut, turn it off, put it away and leave the dan-
ger zone via the planned escape route. Look out for 
falling branches and do not trip.
•  Be alert to signs that the tree is starting to fall: crack-

ing sounds, widening of the felling cut, or movement 
in the upper branches.

•  To avoid injury, do not cut down a partially felled 

tree with your saw. Pay special attention to par-
tially felled trees that may be poorly supported. 
If a tree does not fall completely, set the saw aside 
and pull with a cable winch, block and tackle, or 
tractor.

Sawing a felled tree (Bucking)

The term „BUCK“ means to cut a felled tree trunk into 
the desired log length.

m

 Caution: Do not stand on the log while it is being 

cut. Any portion can roll, and you may lose your foot-
ing and control over the device. Never run the saw on 
sloping ground. Make sure you have secure footing 
and distribute your body weight evenly on both feet. 
If possible, put branches, beams or wedges under the 
tree to support it.

Important Notes

•  Always only cut one log at a time.
•  Be careful when cutting splintery wood. You could 

be hit by sharp wood particles. 

•  Cut small logs or branches on a sawhorse. When 

cutting logs, another person should hold the trunk. 
Do not secure the trunk with your leg or foot.

•  If you use the saw in places where trunks and roots 

are tangled, drag the logs into a clear spot, and lift 

the cleared logs first.
