lower left hand portion of the motor housing near the chip deflector. The motor housing is marked: 0, I, II, III. The
"0" designates the straight-line mode. "I" through "III" designate increasing levels of orbital action. Just as with
blade speed, selecting the proper orbital action is largely a matter of operator experience and experimentation on
scrap. The chart shown below is intended as a guideline only.

APPLICATION
BLADE SELECTION
To obtain the best performance from the saw, it is important to select a specific blade for the particular application
and type of material you wish to cut. By doing this you will get a smoother, faster cut and prolong blade life.
NOTE:
This tool is designed to work with T-shank blades. Other types of saw blades are not guaranteed to work
properly and may come loose from the tool.
GENERAL CUTTING
CAUTION:
Always hold the base flush with the workpiece. failure to do so may cause blade breakage, resulting
in a serious injury.
Jig saws cut on the upstroke. It causes the workpiece surface facing upwards to splinter. Therefore, determine
the "good" side of your workpiece, and place your guidelines for cutting on the opposite side. Properly support
and clamp the workpiece with the "good" side down, and with the guidelines clearly visible and unobstructed
(above & below) the surface to be cut.
To start the cut, place the front edge of the saw base on the workpiece and align the blade with the previously
drawn guideline. Make sure the blade does not contact the workpiece. Turn the saw on, wait for the blade to
reach full speed and slowly move the blade into the workpiece. Apply only enough downward pressure to keep
the saw steady on the workpiece and only enough forward pressure to keep the blade cutting.
EDGE GUIDE CUTTING
This jig saw is equipped with a Rip Guide. It can be used for making cross cuts and rip cuts.
To Install the Rip Guide
1. use Allen wrench provided, loosen the two screws at the front of the base.
2. Insert the rip guide arm through two slots with the scale side up.
3. Adjust rip guide to the desired width and lock in place by tightening the two screws.
BEVEL CUTTING
Bevel cutting angles may be adjusted from 0° to 45° right or left. Angles for cuts from 0° to 45° in 15°
increments are marked on a scale on both the left and right side of the base.
To Adjust the Bevel Cutting Angles
1. using Allen wrench provided, loosen the two base screws until the base can be moved.
2. Slide base backward until base screws can move freely in the grooves in base.
3. Align the mark, on the base, of the desired angle with the edge of motor housing.
4. Once the desired angle is reached, tighten the base screws securely.
INTERIOR CUTOUTS
An interior cutout is needed when a cutting pattern is located in the workpiece without a lead-in cut from an edge.
These cuts can be performed using one of two methods: either using starting holes or by plunge cutting.
SCROLL CUTTING
Scroll cuts can be made with the jig saw by guiding the direction of the cut with applied pressure on the handle.
WArNING:
or damage to the material being cut.
Applications
for clean cuts in wood and plywood. for cutting mild steel, stainless
steel, and plastics.
for cutting mild steel, aluminum, and hard wood.
for cutting wood and plywood.
for fast, aggressive cutting in wood and plywood.
Excessive side pressure to the blade could result in broken blades
