WARNING: To avoid possible serious injury,
keep hands and fingers from between the gear
housing and saw blade clamp.
SCROLLER KNOB LOCK
See Figure 7.
Your saw is equipped with a thumb operated lock for
locking the knob in (4) positions, 90 ° apart. Lock and
unlock the scroller mechanism of your saw by rotating
the lock, located on the front of your saw, in the
direction of the arrows as shown in Figure 7. Looking
the knob as shown in Figure 7 permits cuts to be
made close to walls and corners. For scroll cutting,
the lock must be in the unlocked position for free
rotation of the saw bar.
SCROLL CUTTING
See Figures 8 and 9.
Your auto-scroll saw is designed to permit 360 °
rotation of the saw blade so that intricate designs may
be cut with minimum effort with the blade installed in
the back slot. Your saw may be operated either by
rotating the auto scroller knob manually with your free
hand, or by guiding the direction of the cut with
applied pressure on the handle as shown in figures 8
and 9.

_k, WARNING: Excessive side pressure to the
blade could result in broken blades or damage to
the material being cut.
METAL CUTTING
Many kinds of metalscan 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 or higher speed. If blade heats excessively,
use lower speed. If blade teeth become filled or clogged
when cutting soft metals, such as aluminum, use a
coarser-tooth blade or lower speed. We recommend use
of oil when cutting metals to keep blades cool, increase
cutting action, and prolong blade life. Clamp the work
firmly and saw 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 saw close to the vise. To cut thin
sheet materials, "sandwich" the material between
hardboard or plywood and clamp the layers to eliminate
vibration and material tearing. By doing this, the material
will be cut smoothly. Lay out 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.
