6.2 Extension cords
The use of extension cords is discouraged. Try to
position machines within reach of the power
source. If an extension cord must be used, make
sure it is heavy enough to carry the current your
product will draw. An undersized cord will cause a
drop in line voltage resulting in loss of power and
overheating. Table 2 shows correct size to use
depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.

7.0 Adjustments
Note: Figures may show either JB-10P or JB-10R,
but procedures are identical for both models,
unless indicated otherwise.
7.1 Tools required for adjustments
Hex (Allen) wrenches, 2.5, 5 mm
Open-end wrench, 14 mm
7.2 Depth of cut
1. Loosen locking handle (A, Figure 7-1) on each
side of machine.
2. Rotate knob (B) until desired depth is shown
on scale in millimeters (C, Figure 7-2). NOTE:
The scale is only a general guide based upon
45° position. Actual depth will vary depending
upon chamfering angle.
3. Retighten locking handles (A).
Note: Locking handles are adjustable: Lift up
on handle, rotate it to more convenient
position, then release.
7.3 Chamfer angle
1. Remove stop screw (D
1
, Figure 7-2) on both
sides of machine.
2. Loosen screw (D
2
) on both sides of machine.
3. Tilt guide plate assembly (E) until screw hole
aligns with 15, 30 or 45 degrees.
4. Insert stop screw (D
1
) on both sides.
5. Tighten all four screws.

7.4 Bead positioning
Steel beads in the guide plates can be positioned
to reduce friction between workpiece and guide
plates, resulting in smoother, more rapid progress
of the cut. This is particularly useful when
workpiece surface is rough or textured.
1. Loosen hex nut (F
1
, Figure 7-3) with 14mm
wrench.
2. Turn set screw (F
2
) with 5mm hex wrench to
raise steel bead (G) slightly above guide plate
surface.
3. Retighten hex nut(s).
