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 24 through a clamp, then
through the slots provided in the footplate,
from either side of footplate (Fig. 15). (If
possible, place second clamp on bar from
opposite side of jig saw).
5. Remove center pin from end of the Guide
26 (Fig. 12), push center 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 & GST18V-
60C / GST18V-60BC 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 fr om inside the
intended radius.
– When cutting wheels or discs, cut from
the outside the intended radius.
7. Hook clamp(s) onto footplate, and position
the Guide 26 to that adjusted radius mea-
surement (Fig. 15).
8. Place Lock Knob(s) 25 on proper side of
clamp(s) and securely tighten lock knob(s)
on the clamp(s).
9. Insert battery pack onto jig saw, hold the saw
firmly, squeeze trigger (GST18V-60C model
only) or slide the On/Off Switch forward
into the "on" position (GST18V-60BC model
only) and slowly push the saw forward.

CIRCLE-CUTTING TIPS:
• Place small wedges in the cut as shown in Fig.
15, to keep the inner circle from spreading
when near the end of the cut.
• Use a thick jig saw blade, such as the Bosch
T101TP or T144DP whenever possible.
• Make sure that the jig saw's orbital setting is
at 0 (zero).
• Cut slowly so the blade will stay straight in
the cut.
