Operating Tips
PARALLEL CUTTING
Parallel cuts can be made from 5/8” to 6” in
from the edge of the workpiece.
1. The guide fence surface needs to be posi-
tioned ALONGSIDE the workpiece (Fig. 14).
2. Hook clamp(s) onto footplate, adjust fence
to desired width and place lock knob(s) on
proper side of clamp(s).
3. Securely tighten lock knob(s) on the
clamp(s) (Fig. 13).
4. Insert battery pack onto jig saw, hold the
saw firmly, squeeze trigger and slowly push
the saw forward (Fig. 14).
CIRCLE CUTTING
Circle cuts can be made from 5” to 16-1/2” in
diameter.
1. Determine the center point of the desired
circle.
2. Drill a 3/16” (5 mm) center hole 7/8” (23
mm) deep in workpiece. (For enhanced pre-
cision, drill the hole using a drill press, if
possible).
3. Drill or plunge cut near the circle’s edge,
turn saw off, and disconnect battery pack
from the tool.
4. Insert guide bar through a clamp, then
through the slots provided in foot, from ei-
ther side of foot (Fig. 13). (If possible, place
second clamp on bar from opposite side of
jig saw).
5. Remove guide pin from end of guide, push
pin through proper hole provided in guide,
then into center hole of workpiece (Fig. 15).
– When used with a Bosch JS572 jig saw
or the GST18V-50 / GST18V-50B cordless
jig saw, the holes labeled for the JS572
should be used.
– For other jig saws, one of the other holes
should be used.
6. Measure the distance from the center of the
hole to the desired circle radius. Adjust that
measurement as necessary to account for
the width of the blade:
– When cutting a hole, cut from inside the
intended radius.
