Cutting Metal; Cutting With A Straight Edge - Craftsman 320.28223 Operator's Manual

CUTTING METAL
When cutting metal, always clamp down the metal workpiece to a stable surface
and use a metal cutting blade. Be extremely careful to move the saw very slowly
as you cut. Use the low speeds (position 1,2 or 3 on the variable speed dial).
Also use the LOW position on the orbital control lever.
Do not twist, bend or force the blade, if the saw jumps or bounces as you cut,
change to a blade with finer teeth, if the blade begins to clog when cutting soft
metal, change to a blade with coarser teeth.
For easier cutting, lubricate the blade with a stick of cutting wax (if available) or
cutting oil when cutting steel. Thin metal should be sandwiched between two
pieces of wood or tightly clamped on a single piece of wood (wood on top of the
metal). Draw the cut lines or design on the top piece of wood.
When cutting aluminum extrusion or angel iron, clamp the work in a bench vise
and saw close to the vise jaws.
When sawing tubing with a diameter larger than the blade is deep, cut through the
wall of the tubing and then insert the blade into the cut, rotating the tube as you saw.
1. When cutting metals, a suitable cooling/cutting oil must be used.
2. Spread the oil onto the blade or workpiece at regular intervals during cutting
in order to reduce wear or overheating the blade.
WARNING: Always unplug the saw from the power source before oiling the
blade or making any adjustments or attaching accessories.
,_ WARNING: Always clamp and secure workpiece securely. Always maintain
proper control of saw. Failure to clamp and support workpiece and loss of
control of saw could result in serious injury.
CUTTING WITH A STRAIGHT EDGE (Fig. 15)
1. Mark the the desired cut line.
Fig. 15
2. Clamp a straight edge
parallel to the cut line at a
distance from the cut line
that is equal to the distance
between the blade and the Straight
edge of the saw base. edge
3. As you cut, keep the saw
base edge flush against the
straightedge and fiat on the
workpiece.
NOTE: Always use a rough-cut
blade whenever possible.
_!_ WARNING: To avoid
accidents, always disconnect the tool from the power source before making any
adjustments or attaching accessories.
