**Used on 12 gauge - 20 amp circuit.
NOTE: AWG = American Wire Gauge
When working with the product outdoors, use an extension cord that is designed for outside use. This is indicated by the letters “W-A” or “W” on the cord’s jacket.
Before using an extension cord, inspect it for loose or exposed wires and cut or worn insulation.
WARNING:
Keep the extension cord clear of the working area. Position the cord so that it will not get caught on lumber, tools, or other obstructions while you are working with a power tool. Failure to do so can result in serious personal injury.
WARNING:
Check extension cords before each use. If damaged replace immediately. Never use the product with a damaged cord since touching the damaged area could cause electrical shock resulting in serious injury.
Electrical Connection
This product is powered by a precision-built electric motor. It should be connected to a power supply that is 120 V, AC only (normal household current), 60 Hz. Do not operate this product on direct current (DC). A substantial voltage drop will cause a loss of power and the motor will overheat. If the product does not operate when plugged into an outlet, double check the power supply.
SPEED AND WIRING
The no-load speed of this product is approximately 3,000 sfpm. This speed is not constant and decreases under a load or with lower voltage. For voltage, the wiring in a shop is as important as the motor’s horsepower rating. A line intended only for lights cannot properly carry a power tool motor. Wire that is heavy enough for a short distance will be too light for a greater distance. A line that can support one power tool may not be able to support two or three products.
Grounding Instructions
This product must be grounded. 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 product 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.
WARNING:
Improper connection of the grounding plug can result in a risk of electric shock. When repair or replacement of the cord is required, do not connect the grounding wire to either flat blade terminal. The wire with insulation having an outer surface that is green with or without yellow stripes is the grounding wire.
Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the product is properly grounded.
Repair or replace a damaged or worn cord immediately.
This product is for use on a nominal 120 V circuit and has a grounding plug similar to the plug illustrated in figure 1, page 17. Only connect the product to an outlet having the same configuration as the plug. Do not use an adapter with this product.

CLAMPING BAND SAW TO WORKBENCH
See Figure 5, page 18.
If the band saw is to be used as a portable tool, it is recommended that you fasten it permanently to a mounting board that can easily be clamped to a workbench or other supporting surface. The mounting board should be of sufficient size to avoid tipping of saw while in use. Any good grade plywood or chipboard with a 3/4 in. thickness is recommended.
Mount saw to board using holes in saw base as a template for hole pattern. Locate and mark the holes where the band saw is to be mounted.
Follow the last three steps in the section Mounting Band Saw to Workbench, shown above.
If lag bolts are used, make sure they are long enough to go through holes in the saw base and material the saw is being mounted to. If machine bolts are being used, make sure bolts are long enough to go through holes in the saw base, the material being mounted to, and the lock washers and hex nuts.
Note: It may be necessary to countersink hex nuts and washers on bottom side of mounting board.
WARNING:
Do not connect to power supply until assembly is complete. Failure to comply could result in accidental starting and possible serious personal injury.
MOUNTING BAND SAW TO WORKBENCH
If the band saw is to be used in a permanent location, we recommend that you secure it to a workbench or other stable surface. When mounting the saw to a workbench, holes should be drilled through the supporting surface of the workbench.
Each hole in the saw base should be bolted securely using bolts, lock washers, and hex nuts (not included).
Place band saw on the workbench. Using the saw base as a pattern, locate and mark the holes where the band saw is to be mounted.
Drill holes through the workbench.
Place band saw on the workbench aligning holes in the saw base with the holes drilled in the workbench.
Insert bolts (not included) and tighten securely with lock washers and hex nuts (not included).
Note: All bolts should be inserted from the top. Install the lock washers and hex nuts from the underside of the bench.

ASSEMBLY
SQUARing the saw table TO THE BLADE
See Figure 8, page 19.
Turn the lock knob counterclockwise to unlock the blade guide assembly. Turning the blade guide knob clockwise, raise the blade guide assembly as far as it will go. Turn the lock knob clockwise to retighten.
Place a small combination square on the saw table beside the blade.
Loosen the table lock knob and rotate the angle adjustment knob to tilt the saw table up or down to align table 90° to blade (0° position). Retighten the table lock knob.
Using a 4 mm hex key, adjust the zero stop set screw until the set screw just touches the saw housing.
Check squareness of the saw table to the blade. Make readjustments if necessary.
Loosen screw on scale indicator with a phillips screwdriver and align scale indicator to zero.
Tighten all screws securely.
ADJUSTING BLADE TENSION
See Figures 9 - 10, page 19.
Remove the switch key.
Before using the band saw, turn the blade tension knob on the top of the saw clockwise to engage tension.
Note: Adjustments of blade tension can be made at anytime.
Another method of checking blade tension has to do with the sound the blade makes when plucked like a guitar string.
Pluck the back straight edge on the coasting side opposite the blade guides while turning the tension knob. Sound should be a musical note. Sound becomes higher pitched as tension increases.
Using either method to check blade tension can be developed with practice.
Never increase blade tension so tight as to completely compress the spring. When completely compressed, the spring can no longer act as a shock absorber.
Note: Too much tension may cause the blade to break. Too little tension may cause the blade to slip on the wheels.
tracking the BLADE
See Figure 10, page 19.
Note: Adjust blade tension properly before making tracking adjustments. Check that the blade guides are not interfering with the blade.
To adjust:
Open the front cover by releasing the upper and lower latches. Watch the blade’s position on the upper tire through the tracking view window as, by hand, you slowly turn the upper wheel clockwise. If the blade moves away from the center of the tire, the tracking must be adjusted.
If the blade has moved left or right of center:
Note: It may be necessary to loosen the hex nut for a larger range of adjustments. Be sure to retighten after adjusting.
Turn the blade tracking knob (clockwise if blade has moved left and counterclockwise if blade has moved right) while turning the wheel by hand until the blade moves back and rides in the center of the tire.
Check the position of the blade on the lower tire. The blade should be completely on the tire. If not, adjust the tracking until the blade is on both tires.
Rotate the upper wheel by hand in a clockwise direction for a few more turns. Make sure the blade stays in the same location on the tires. Readjust, if necessary, until blade is tracking properly.
Close front cover and relatch.
Note: The 1/8 in. blade may not track properly in the center of the wheel. It may be better to track this blade on the back half of the upper wheel.
warning:
The blade guides have been preset at the factory. These settings are functional for some applications. We recommend that you check and adjust blade guide settings before first use of your saw. Refer to “Adjusting blade guide support, thrust bearings, and blade guide bearings” procedures explained in the adjustments section of this operator’s manual.

To avoid blade contact, adjust the blade guide assembly to just clear the workpiece. Failure to do so could result in serious personal injury.
APPLICATIONS
You may use this tool for the purposes listed below:
Scroll cutting and circle cutting of wood and wood composition products
Various straight line cutting operations in wood and wood composition products
BASIC OPERATION OF THE BAND SAW
A band saw is basically a “curve cutting” machine that can also be used for straight-line cutting operations like cross cutting, mitering, beveling, compound cutting, and resawing. When using the band saw for straight line cutting, the user can install a fence using an appropriately sized piece of wood clamped to the table with “C” clamps. It is not capable of making inside or non-through cuts.
This band saw is designed to cut wood and wood composition products only.
Before starting a cut, watch the saw run. If you experience excessive vibration or unusual noise, stop immediately. Turn the saw off, remove the switch key, and unplug the saw. Do not restart until locating and correcting the problem.
CUTTING PROCEDURES
Hold the workpiece firmly against the saw table.
Use gentle pressure and both hands when feeding the work into the blade. Do not force the work; allow the blade to cut.
The smallest diameter circle that can be cut is determined by blade width. A 1/4 in. wide blade will cut a minimum diameter of 1-1/2 in.; a 1/8 in. wide blade will cut a minimum diameter of 1/2 in.
Keep your hands away from the blade. Do not hand hold pieces so small your fingers will go under the blade guard.
Avoid awkward operations and hand positions where a sudden slip could cause serious injury from contact with the blade. Never place hands in blade path.
Use extra supports (tables, saw horses, blocks, etc.) when cutting large, small or awkward workpieces.
Never use a person as a substitute for a table extension or as additional support for a workpiece that is longer or wider than the basic saw table.

OPERATION
When cutting irregularly shaped workpieces, plan your work so it will not pinch the blade. For example, a piece of molding must lay flat on the saw table. Workpieces must not twist, rock or slip while being cut.
When backing up the workpiece, the blade may bind in the kerf (cut). This is usually caused by sawdust clogging the kerf or when the blade comes out of the guides. If this happens:
Place the switch in the OFF position. Wait until the saw has come to a full and complete stop, then remove the switch key from the switch assembly. Store key in a safe place.
Unplug the saw from the power source.
Wedge the kerf open with a flat screwdriver or wooden wedge.
Open front cover and turn the upper wheel by hand while backing up the workpiece.
RELIEF CUTS
Relief cuts are made when an intricate curve (too small a radius for the blade) is to be cut. Cut through a scrap section of the workpiece to curve in pattern line then carefully back the blade out. Several relief cuts should be made for intricate curves before following the pattern line as sections are cut off of curve “relieving” blade pressure.
SCROLL CUTTING
For general type scroll cutting, follow the pattern lines by pushing and turning the workpiece at the same time. Do not try to turn the workpiece while engaged in the blade without pushing it – the workpiece could bind or twist the blade.
REMOVING JAMMED MATERIAL
Never remove jammed cutoff pieces until the blade has come to a full and complete stop.
Place the switch in the OFF position. Wait until the saw has come to a full and complete stop, then remove the switch key from the switch assembly. Store key in a safe place.
Unplug the saw from the power source before removing jammed material.
AVOIDING INJURY
Make sure saw is level and does not rock. Saw should always be on a firm, level surface with plenty of room for handling and properly supporting the workpiece.
Bolt saw to the support surface to prevent slipping, walking or sliding during operations like cutting long, heavy boards.
Turn saw off, remove switch key, and unplug cord from the power source before moving the saw.
Do not remove jammed cutoff pieces until blade has come to a full and complete stop.
Choose the right size and style blade for the material and type of cut you plan to do.
Make sure that the blade teeth point down toward the saw table, that the blade guides, thrust bearings, and blade tension are properly adjusted, that the blade guide knob is tight, and that no parts have excessive play.
To avoid accidental blade contact, minimize blade breakage, and provide maximum blade support, always adjust the blade guide assembly to just clear the workpiece.
Use only recommended accessories.
With the exception of the workpiece and related support devises, clear everything off the saw table before turning the saw on.
Properly support round materials such as dowel rods or tubing because they have a tendency to roll during a cut causing the blade to “bite”. To avoid this, always use a “V” block or clamp workpiece to a miter gauge.
Before removing loose pieces from the saw table, turn saw off and wait for all moving parts to stop.
LOCKING THE SWITCH
See Figure 12, page 20.
Place the switch in the OFF position. Wait until the saw has come to a full and complete stop, then remove the switch key from the switch assembly. Store key in a safe place.
