- Position and set short logs safety prior to sawing. Only saw wood or wooden objects.

When sawing, always take care to avoid hitting stones, nails, etc, as these could

be thrown up

or 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 teeth (17) 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.

Should the chain touch earth/soil the chain will become instantly blunt.

- 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 tree wedges to

free 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 company

should be notified immediately.The chain saw operator should keep on the uphill

side of the terrain as the tree is likely to roll or slide downhill after it is felled.

- An escape path should be planned and cleared as necessary before cuts are started.

The escape path should extend back and ideally diagonally to the rear of the expected line

of fall.

- 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.

- Notching undercut: Make the notch (x-w)1/3 the diameter of the tree, perpendicular to

the direction of falls as make the lower horizontal notching cut. This will help to avoid

pinching either the saw chain or the guide bar when the second notch is being made.

- Felling back cut: make the felling back cut (Y)at least 50 mm higher than t

2.3.6 CUTTING WOOD UNDER TENSION. (See Fig.4)

There is a high risk of accidents when sawing logs, branches or stems 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 chain saw 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 nish the cut from above (Z) in order to avoid

log splitting or jamming of the chain saw.

2.3.7 GENERAL CUTTING INSTRUCTIONS.

1). Felling trees. (See Fig. 5)

Always wear a hard-hat with visor 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.
