TM 9-243
USING THE HACKSAW - Continued
2
Secure the material (4) to be cut in a vise or other
holding device to avoid vibration which may snap
the blade.
3
To make an accurate cut, use a file (5) to make a
notch for guiding the first strokes of the saw.
4
Steady the saw by holding the handle with the right
hand and the frame with the left.
5
Hold the blade parallel to the work surface and cut
on the push stroke, being careful not to bear down
too hard. Draw the blade back using no pressure
each time.
6
Saw at a rate not to exceed 40 to 50 strokes per
minute.
CARE OF SAWS
1.
Store blades in a dry place and apply a light coat of
oil when not in use. This will keep the blades from
rusting.
2.
Never use a woodcutting saw to cut through nails
or other metal.
3.
Between cuts, place saw flat on a work bench or in
a spot where teeth cannot be damaged.
4.
Avoid placing heavy tools or objects on saw blades
as this can result in distortion of the blade.
5.
Do not force the saw if it binds. Use a wedge to
spread the cut.
6.
Replace damaged saw handles with new ones
immediately when needed.
7.
To keep saw teeth in top condition, touch up the
teeth with a file occasionally.
8.
Always loosen the blade tension on a hacksaw
when not in use.
9.
Always protect saw blade teeth from coming in
contact with metal or other material that may dam-
age them.
10.
Always remove the nested saw blade from the
handle for storage.
