CUTTING LOGS
Observe the following safety instructions:
Support logs so that the face sides at the cut do not close in against each other, which
would result in the chain being jammed or pinched.
Position and set short logs safely prior to sawing. Saw only wood or wooden objects.
When sawing, always take care to avoid hitting stones, nails etc, as these could be thrown up, cause damage to
the chain or serious injury to the operator or bystanders.
Keep a running saw clear of wire fencing or the ground.
Use of the saw to thin out branches or bushes is not approved. Length cuts must be carried out with care, as
leverage with the gripping spike is not possible. Saw at a flat angle to avoid kickback.
When working on a slope, operate above or to the side of the trunk or laying tree.
Be careful not to trip over tree stumps, branches, roots, etc.
CUTTING WOOD UNDER TENSION
There is a high risk of accidents when sawing wood, branches or trees under tension. Be extremely careful.
Leave saw jobs like these to professionals.
When sawing logs supported on both ends, start the cut from above (Y) about 1/3 of the diameter into the log
and then finish the cut (Z) from below, in order to avoid contact of the chainsaw with the ground. When
sawing logs supported on only one end, start the cut from below (Y) about 1/3 of the diameter into the log and
finish the cut from above (Z) in order to avoid splitting or jamming of the chainsaw.
FELLING TREES
Always wear a hard hat to protect your head against falling branches.
The chainsaw can only be used to fell trees smaller in diameter than the length of the guide bar.
1.
Secure work area. Ensure no persons or animals are in the vicinity of the falling tree. Never attempt to
free a jammed saw with the motor running. Use wooden wedges to free the chain and guide bar. When
cutting and felling operations are being performed by two or more persons, at the same time, the felling
operations should be separated from the cutting operation by a distance of at least twice the height of the
tree being felled. Trees should not be felled in a manner that would endanger any person, strike any utility
line or cause any property damage. If the tree does make contact with any utility line, the relevant utility
owner/company should be notified immediately. The chainsaw operator should keep on the uphill side of
the terrain as the tree is likely to roll or slide downhill after it is felled.
2.
An escape path should be planned and cleared as necessary before cuts are started. The escape path
should extend back and diagonally to the rear of the expected line of fall.
3.
Before felling is started, consider the natural lean of the tree, the location of larger branches and the wind
direction to judge which way the tree will fall. Remove dirt, stones, loose bark, nails staples, and wire from
the tree.
