METAL CUTTING-Many kinds of metals can be cut with your
saw. Be careful not to twist or bend the blades. DO NOT FORCE. If
the blade chatters or vibrates excessively, use a finer-tooth blade.
If blade teeth become filled or clogged when cutting soft metals, such
as aluminum, use a coarser.tooth blade. We recommend use of kero-
sene when cutting most soft metals and oil when cutting steel to keep
blades cool, increase cutting action, and prolong blade life. Hold the
work firmly and saw close to the holding point to eliminate any
vibration of the work being cut. When cutting conduit, pipe or angle
iron clamp work in a vise if possible and saw close to the vise. To
cut thin sheet material "sandwich" the material between hard board
or plywood and clamp the layers to eliminate vibration and material
tearing. In doing this, the material will be cut smoothly. Layout
your pattern or line of cut on top of the "sandwich."
IMPORTANT-When cutting metal keep exposed portion of saw bar
clean and free of metal chips by wiping frequently with an oily cloth.
Use extreme caution in disposing of oily cloth after completion of
job to prevent potential fire hazard.
The saw is equipped with- a thumb operated lock for locking the
knob in four (4) positions (90. apart). The indicator on front of
swivel knob indicates direction of blade cutting edge. For scroll
cutting the lock must be in the unlocked position for free rotation
of saw bar. Use sufficient forward pressure to permit blade to cut
freely and follow the scribed line with gentle rotation of swivel knob.
SCROLL CUTTlNG-(See Figs. 4
&
5) Your Scroller Saw is designed
to permit 360. swivel of the saw blade by rotating the contoured
top swivel knob. This feature makes it ideally suited for making fancy
cuts and scallops with radii as small as 3/16 inch. It is designed to
cut in corners and close places without the necessity of rotating and
turning the complete saw (See Fig. 5). It is ideal for cutting electrical
outlet and switch box holes, sink and lavatory cut-outs and many
other uses.
INSTALLING BLADES-(See Fig. l)-IMPORTANT-BE SURE
POWER CORD IS DISCONNECTED FROM POWER SUPPLY.
Loosen both blade screws (A) with screwdriver, and insert saw blade
into slot in saw bar (B) as far as it will go.
Tighten side blade screw firmly against blade, then tighten front
blade scrl"( firmly against blade. Excessive pressure on blade during
operation- of the saw can break blade. In the event that this hapPllns all
saw blades, except the 10.tooth tapered back, 6" blade can be reused
by loosening t"- two blade screws until portion left in clamp drops out,
then putting the"remainder of the blade back into the clamp and retight.
ening the blade screws. It may be necessary to flatten tooth set in area
to be inserted into clamp when reusing broken blade.
NOTE:
THE PIN IN THE SAW BAR IS USED ONLY AS A STOP AND
IS NOT DESIGNED TO FIT IN THE NOTCH OF THE BLADE SHANK.
CRAFTSMAN SABRE SAW ~LADES HAVE A UNIVERSAL SHANK
THAT IS DESIGNED TO FIT ALL SABRE SAWS.
GENERAL CUTTING-The angle of cut on your saw maybe set at
any point from O. to 45. right or left. (See Fig. 2)-IMPORTANT-
BE SURE POWER CORD IS DISCONNECTED FROM POWER SUP.
PL Y. Setting for required angle may be accomplished by loosening
base pivot screws, Key No. 17, (See parts list, page 7), and adjusting
base until index mark is in line with required angle on quadrant
scale. Retighten base pivot screws.
Rest. the front of the base on the work and align cutting edge of
blade with line on work. Move saw forward with a firm downward
pressure on the base and with sufficient forward pressure to permit
blade to cut freely. DO NOT FORCE. Be sure to keep base flat on
work.
To nNIke a straight cut, clamp a piece of wood or straight-edge on
the work, and guide the edge of the saw against the straight-edge.
When cutting against a straight edge or board, cut in one direction
only across the material, don't cut half way and continue cut from
the opposite end. For best results, clamp work to bench.
NOTE: BECAUSE THE TAPERED BACK BLADE, CATALOG #2876,
HAS NO SET IN THE TEETH, IT SHOULD NOT BE USED WHEN
USING A BOARD TO GUIDE THE SAW.
PLUNGE CUTTING--(See Fig. 3)
To cut an inside hole in work,
mark the line of cut clearly. Choose a convenient starting.point and place
the tip of the blade over that point and inside the line on the waste. Rest
curved end of base on work and hold firmly in position. Pull trigger
switch and with saw blade in motion, slowly tilt saw downward until
tip of blade starts cutting work. After blade penetrates work, tilt saw
until the blade is perpendicular to the work. Use only 7-teeth per inch
blade for plunge cutting.
