Felling trees (continued)
Operating the Electric Chainsaw
Notched Undercut.
Cut a notch about 1/3 the diameter of the tree, perpendicular to the direction of
fall .Make the cuts of the notch so they intersect at a right angle to the line of fall. This notch should
be cleaned out to leave a straight line. To keep the weight of the wood off the saw, always make the
lower cut of the notch before the upper cut.
Felling backcut.
The back cut is always made level and horizontal, and at a minimum of 2 in.
above the horizontal cut of the notch.
Never cut through to the notch. Always leave a band of wood between the notch and back cut
(approximately 2 in. Or 1/10 the diameter of the tree).This is called “hinge”or “hinge wood” .It
controls the fall of the tree and prevents slipping or twisting or shoot-back of the tree off the stump.
On large diameter trees, stop the back cut before it is deep enough for the tree to either fall or settle
back on the stump. Then insert soft wooden or plastic wedges into the cut so they do not touch the
chain. The wedges can be driven in, little by little, to help jack the tree over.
NOTE!
When bucking or felling with a wedge, it may be necessary to remove the anti-kickback
device to allow the bar to be drawn through the cut. After the cut is complete, the tip should be
reinstalled immediately.
As tree starts to fall, stop the chain saw and put it down immediately .Retreat along the cleared
path, but watch the action in case something falls your way. Be alert for overhead limbs or branches
that may fall and watch your footing.
WARNING!
Never cut through to the notch when making a backcut. The hinge controls the fall of
the tree, this is the section of wood between the notch and backcut.

brush.
3). Remove stubborn dirt with high pressure air (max. 3 bar).
4). Check for worn or damaged parts. Replace worn parts as necessary or contact an authorised
service centre for repair before using the product again.
5). Regularly check for obvious defects such as loose, dislodged or damaged cutting device, loose
fixings and worn or damaged components.
6). Check that covers are undamaged and correctly fitted. Carry out necessary maintenance or
repairs before using the product.
7) Regularly apply lubricant to the chain surface.

Chain sharpening
WARNING!
Wear safety gloves when working on the chainsaw and close to it!
Periodically sharpen the blades as follows:
1. Disconnect the cord from the mains supply.
2. Wear protective gloves.
3. Ensure the chain is correctly tensioned and not too loose.
4. Engage the chain brake (10) to lock the chain on the bar (“Engage”position) when sharpening.
5. Uses a round file for chain sharpening. Diameter equivalent to 1.1times the cutting tooth depth.
6. File at a horizontal angle 35°to the bar.
7. File from inside towards outside of the tooth only.
8. Sharpen each tooth equally by using the same number of strokes.
9. File at an angle of 90°to the bar.
10. Check the safety depth gauge height in intervals while sharpening. Use depth gauge measuring
instrument to check the height of the depth gauge.
