Different cuts for BUCKING (Fig. D)

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 rmly and maintain control. The saw will

push backwards (towards you).

Caution: Never hold the saw upside down for an

undercut. In this position, you have no control over

the device. Always execute the rst cut on the

compression 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 rst 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 rst 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 rst 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 rst cut to

prevent the saw from becoming jammed.

Limbing and Trimming

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.

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 rmly with both

hands. Ensure safe standing position and

balance.

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

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

diameter at a right-angle to the falling direction.

Make the lower horizontal wedge cut rst (Fig. B,

No. 1). This will prevent the saw chain or the guide

bar becoming 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

approximately 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.

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

danger 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:

cracking 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

partially 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.

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

Any portion can roll, and you may lose your footing

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 rst.
