Breakdown No. 7
Using a Log-Saw
1: Examine the saw.
2: Select suitable support for timber to be cut.
3: Grasp the saw.
4: Saw the timber.
1: Examine the saw.
Check teeth are sharp and not damaged. The blade can be removed and new blade fitted if necessary. Use log-saw for cross cutting only.
2: Select suitable support for timber to be cut.
Raise timber to convenient height on blocks or similar supports allowing space for the saw to pass backwards and forwards horizontally. If supports are not available timber can be cut on the ground, but timber must be turned as the cut proceeds to avoid the saw teeth fouling the ground. In thin seams particularly, timber is often cradled between the foot and the leg.
3: Grasp the saw.
Grasp the saw firmly without strain round the grip provided on the frame.
4: Saw the timber.
Timber supported off the ground:
| |
(a) |
Place left leg forward, right leg back and left hand on timber to steady it. Hold saw in right hand.
|
| |
(b) |
Position saw on top of timber and on waste side of cutting line.
|
| |
(c) |
Move saw lightly across top of timber to make a start, keeping blade and forearm horizontal and in line with right shoulder.
|
| |
(d) |
Keep blade upright in the cut and gradually lengthen stroke and increase pressure until full length of blade is used. If the timber can be firmly wedged on its supports, the left hand can be moved over to the top of the saw frame to assist in controlling the saw.
|
| |
(e) |
Finish cut cleanly. Turn timber and finish cut.
|
Timber on the ground:
| |
(a) |
Proceed as described above but kneel to lower body.
|
| |
(b) |
Turn timber as necessary to avoid teeth of saw fouling the ground.
|
GENERAL NOTE: When using saw with the left hand, body positions stated should be reversed.
