SAFETY INSTRUCTIONS

Clearing‘s ABC

A.Always use the correct equipment.

B.Always have well adjusted equipment.

C.Follow the safety instructions.

D.Organise the work well.

E.Always use full throttle when applying the blade.

F.Always use a sharp blade.

G.Avoid stones.

H.Guide the direction of fall (use the wind).

!WARNING!

Avoid cutting in the cutting region between 12 and 3 o‘clock on the blade. Kickback can occur due to the blade‘s rotation speed in this area of the blade when applied on thick stems.

Working methods

Before you start clearing, check the clearing area, its condition, slopes, if there are stones, pits, etc.

Thereafter start at the end which is easiest, and make a good start to the clearing.

Work systematically to

and from and across the area. Each stroke should encompass a working area of 4-5 metres. This then utilises the full working area of the machine in both directions and provides the operator with an easy and variable working area to work through.

The length of the pathway should be approx. 75 m. Move the fuelling station as work progresses.

On sloping ground the pathway should run parallel to the slope. It is far easier to work along a slope then up and down a slope.

The pathway should be

planned so that you avoid going over ditches or other obstacles. Also adapt the pathway to the wind conditions so that the cleared stems fall on the part of the stand that has been cleared.

Forestry clearing using a saw blade

When applying the blade to heavier stems the risk of kickback increases. You should therefore avoid applying the blade on the cutting area between 12 and 3 o‘clock.

To fell to the left, the lower section of the tree should carry to the right. Angle the blade and move it with a resolute movement diagonally down to the right. At the same time press against the stem using the blade guard. Apply the blade on the area between 3-5 o‘clock. Use full throttle when applying the blade.

To fell to the right, the lower section of the tree should carry to the left.

Angle the blade and move it with a resolute movement diagonally up to the left. Apply the blade on the area between 3 and 5 o‘clock so that the blade‘s direction of rotation carries the lower section of the tree to the left.

To fell a tree forwards the lower section of the tree should be drawn backwards. Draw the blade backwards with a quick and resolute movement.
