Plunge Cutting - Ryobi JS651L Operator's Manual

ANGLE CUTTING (BEVEL CUTTING)
See Figures 9 - 10, page 12.
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.
An arrow under the motor assembly provides an indicator at
each of the above mentioned 15° increments. A protractor
is recommended when accurate cuts are required.
 Unplug the saw.
 Using the 1/8 in. hex key provided, loosen the base pivot
screw until the base can be moved.
 Rotate base to desired bevel angle.
NOTE: To prevent the blade clamp from contacting the
thumb screw, it may be necessary to move or remove the
edge guide knob when making bevel cuts.
 Tighten base pivot screw.
SCROLL CUTTING
See Figure 11, page 12.
Scroll cuts can be made with the jig saw by guiding the direc-
tion of the cut with applied pressure on the handle as shown.
NOTE: Tighter tolerance scroll cutting may require the use
of a scroll cutting blade (not included).
WARNING:
Excessive side pressure to the blade could result in
broken blades or damage to the material being cut.

PLUNGE CUTTING

See Figures 12 - 14, page 12 - 13.
Depending on the thickness of the material being cut, you
may need to drill a pilot hole before making plunge cuts.
WARNING:
To avoid loss of control, broken blades, or damage to
the material being cut, always use extreme caution when
making plunge cuts. We do not recommend plunge cut-
ting on materials other than wood.
To make plunge cuts using pilot holes:
 Mark the line of cut clearly on the workpiece.
 Drill a pilot hole inside the area marked by the line of cut.
The pilot hole should be large enough to slide the blade
through the material.
 Slowly lower the blade through the pilot hole in the
workpiece until the base contacts the work piece. Fully
squeeze the switch trigger to start the saw.
OPERATION
 Do not move the base forward until the blade is entirely
through the workpiece and the base is in complete con-
tact with the workpiece.
 Move the saw forward to complete the opening.
To make plunge cuts without using pilot holes:
 Mark the line of cut clearly on the workpiece.
 Tilt the jig saw forward so that it rests on the front edge
of the base and blade will not come in contact with the
workpiece when the tool is turned on.
 Make sure the blade is aligned with the area to be cut.
 Fully squeeze the switch trigger and slowly lower the
blade into the workpiece until the blade cuts through the
workpiece.
 Continue lowering the blade into the workpiece until the
base rests flat on the work surface, then move the jig saw
forward to complete the opening.
 Use only the 7 teeth per inch blade for this type of cut.
METAL CUTTING
See Figure 15, page 13.
NOTE: The jig saw has to be in the no-orbit mode to cut
metals and conduit. Set the orbital adjustment knob to "0."
Refer to the Orbital Motion section earlier in this manual
for more details.
Many kinds of metals can be cut with the saw using a metal
blade. Be careful not to twist or bend the blades. Do not
force. If the blade chatters or vibrates excessively, use a
finer-tooth metal-cutting blade. 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 lubricant
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 mate-
rial tearing. By doing this, the material will be cut smoothly.
Lay out your pattern or line of cut on top of the "sandwich."
NOTE: 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.
