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.
METAL CUTTING
See Figure 8.
GENERAL CUTTING
See Figure 6.
OPERATION
Fig. 6
Hold your saw firmly in front of and clearly away from you.
Make sure saw blade is clear of any foreign material. Be sure
material to be cut is held firmly. Small work pieces should be
securely clamped in a vise or with clamps to the work bench
or table. Mark the line of cut clearly. Depress the lock-off
button, then pull switch trigger to start the cutting action.
Place the base assembly against the work, then move the
blade into the work. Do not force. Use only enough pressure
to keep the saw cutting. Let the blade and saw do the work.
Use of excessive pressure that causes bending or twisting of
the blade may result in broken blades.
PLUNGE CUTTING
See Figure 7.
Fig. 8
Fig. 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.
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.
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.
