Grounding Instructions

Caution: This tool must be grounded while in use to protect the operator from electric shock.

In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric
current to reduce the risk of electric shock. This tool is equipped with an electric cord having an
equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet
that is properly installed and grounded in accordance with all local codes and ordinances.

Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a qualified
electrician.

Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The
conductor, with insulation having an outer surface that is green with or without yellow stripes, is the
equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not
connect the equipment-grounding conductor to a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely
understood, or if in doubt as to whether the tool is properly grounded. Use only three wire extension
cords that have three-prong grounding plugs and three-pole receptacles that accept the tool’s plug.

Repair or replace a damaged or worn cord immediately.

115 Volt Operation

As received from the factory, your bandsaw is ready to run at 115 volt operation. This bandsaw, when
wired for 115 volts, is intended for use on a circuit that has an outlet and a plug that looks the one
illustratedinFigure A. A temporaryadapter, which looks like the adapter as illustrated in Figure B, may
be used to connect this plug to a two-pole receptacle, as shown in Figure B if a properly grounded outlet
is not available. The temporary adapter should only be used until a properly grounded outlet can be
installed bya qualified electrician. This adapter is not applicable in Canada. The green colored rigid
ear, lug, or tab, extending from the adapter, must be connected to a permanent ground such as a
properly grounded outlet box, as shown in Figure B.

4

230 Volt Operation

If 230V, single phase operation is desired, the following instructions must be followed:

1. Disconnect the machine from the power source.

2. This bandsaw is supplied with four motor leads that are connected for 115V operation, as shown in

Figure A. Reconnect these four motor leads for 230V operation, as shown in Figure B.

3. The 115V attachment plug supplied with the bandsaw must be replaced with a UL/CSA listed plug

suitable for 230V operation. Contact your local Authorized JET Service Center or qualified
electrician for proper procedures to install the plug. The bandsaw must comply with all local and
national codes after the 230V plug is installed.

4. The bandsaw with a 230V plug should only be connected to an outlet having the same configuration.

No adapter is available or should be used with the 230V plug.

Important: In all cases (115 or 230 volts), make certain the receptacle in question is properly
grounded. If you are not sure, have a registered electrician check the receptacle.

Assembly and Setup

1. With help from another person tilt the

bandsaw just enough to get one set of feet
(A, Fig. 1) underneath the base. Line up
holes and bolt (B, Fig. 1) through the base
into the feet using two hex cap bolts 3/8”­16x4”, two 3/8” lock washers, two 3/8” flat
washers, and two 3/8” plastic flat washers.
Repeat for opposite end.

2. Attach the handle (C, Fig. 2) to the

handwheel (D, Fig. 2).

rest in approximately the center of the
wheel.

3. If adjustment is necessary, loosen the wing
nut (G, Fig. 2) at the top rear of the saw.

4. Adjust tracking by turning the knob (H, Fig.

2) in 1/4 turn increments. Rotate the wheel
forward, and observe the position of the
blade on the wheel. Rotating knob (H, Fig.

2) counter-clockwise should move the blade
towards the front of the wheel. Rotating
the knob clockwise should move the blade
towards the back of the wheel.

Adjusting Blade Tension

1. Disconnect machine from the power

source, unplug.

2. Turn blade tension hand wheel (E, Fig. 2)
counter-clockwise to tension blade, and
clockwise to loosen the tension. A gauge
on the upper wheel slide bracket (F, Fig. 2)
indicates the approximate tension according
to the width of the blade. The JWBS-16
comes with a 3/4” blade so the tension
should be set at 3/4” when using this blade.

• As you become familiar with the saw, you
may find it necessary to change the blade
tension from the initial setting. Changes in
blade width, and the type of material being
cut will have an effect on blade tension.

• Keep in mind that too little, or too much
blade tension can cause blade breakage
and/or poor cutting performance.

Adjusting Blade T racking

5. Continue with adjustments until the blade is
tracking properly.

6. Tighten the wing nut (G, Fig. 2).
