PLUNGE CUTTING
See Figure 7.
Mark the line of cut clearly. Choose a convenient starting
point inside the area to be cut out and place the tip of
the blade over that point. Rest front edge of base (shoe)
assembly on work and hold firmly in position. Depress the
lock-off button, then pull switch trigger to start the cutting
action.
WARNING:
Make sure blade does not touch work
until motor reaches full speed, since this could cause
loss of control resulting in serious injury.
With saw blade at full cutting speed, slowly tilt saw
downward until tip of blade starts cutting work. After
blade penetrates work, tilt saw until blade is perpendicular
to the work.
Never use gasoline since normal sparking of motor could
ignite fumes. Clamp the work firmly and cut close to the
clamping 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 cut close to the vise. To
cut thin sheet material, "sandwich" the material between
hardboard or plywood and clamp the layers to eliminate
vibration and material tearing.
OPERATION
METAL CUTTING
See Figure 8.
Metals such as sheet steel, pipe, steel rods, aluminum,
brass, and copper may be cut with your saw. Be careful
not to twist or bend the saw blade. Do not force. We
recommend cutting oil when cutting most soft metals
and steel. Cutting oil will also keep blades cool, increase
cutting action, and prolong blade life.
