ELECTRICAL

EXTENSION CORDS

• Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the product’s plug. When using a power tool at a considerable distance from the power source, use an extension cord heavy enough to carry the current that the product will draw. An undersized extension cord will cause a drop in line voltage, resulting in a loss of power and causing the motor to overheat.
• 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.
• 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 230-240 V, AC only (normal household current), 50 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 11 m/s. 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 input power 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. Repair or replace a damaged or worn cord immediately.

RESIDUAL RISKS

• Even when the product is used as prescribed, it is still impossible to completely eliminate certain residual risk factors. The following hazards may arise and the operator should pay special attention to avoid the following:
• kick-back of work pieces or parts of work pieces due to improper adjustment or handling damage to the respiratory system
• NOTE: Wear respiratory protection masks containing filters appropriate to the materials being worked. Ensure adequate workplace ventilation. Do not eat, drink or smoke in the work area.
  damage to hearing if effective hearing protection is not worn.

MOUNTING BAND SAW TO WORKBENCH

• If the band saw is to be used in a permanent location, the band saw must be mounted to a firm supporting surface such as a workbench. Four bolt holes have been provided in the saw’s base for this purpose. Bolts (not included) should be of sufficient length to accommodate the saw base, lock washers (not included), hex nuts (not included), and the thickness of the workbench. Tighten all four bolts securely.
• Carefully check the workbench after mounting to make sure that no movement can occur during use. If any tipping, sliding, or walking is noted, secure the workbench to the floor before operating.
• 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.

CLAMPING BAND SAW TO WORKBENCH
See Figure 4.

• 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 19 mm (3/4”) Thickness is recommended.
• 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 the bottom side of the mounting board.
• Mount saw to the 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.

MOUNTING THE SAW TABLE
See Figures 5,

• Remove the d-nut, washers, and wing screw on the saw table.
• Standing at the front of the band saw, slide the saw table past the blade and through the slot moving from the right side of the saw table to the left.
• Holding the saw table with your left hand while pulling the angle adjustment knob away from the saw frame, align the teeth on the saw table bracket into the teeth on the angle adjustment knob. Release the knob.
• Fit the pins on the frame into the slots of the saw table bracket.
• Insert the washer on the threaded end of the table lock lever. Tighten the saw table to the saw frame by turning the table lock lever clockwise.
• Attach the d-nut, washers, and wing screw to the saw table.
• NOTE: the wing screw goes below the saw table.

INSTALLING EXTENSION SUPPORT
See Figure 6. 7.

• Insert the tubes of the extension support into the holes in the saw base from the rear.
• Align the holes on the tubes and those on the saw base.
• Insert locking bolts and tighten with washers and hex nuts.

SQUARING THE SAW TABLE TO THE BLADE
See Figures 8 – 9.

• Turn the lock knob counterclockwise to unlock the blade guide assembly. Turning the blade guide adjustment 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 lever and rotate the angle adjustment knob to tilt the saw table up or down to align the table 90° to the blade (0° position). Retighten the table lock lever.
• NOTE: always make a test cut to insure the squareness of the blade prior to beginning any new project. If not square, it may be necessary to loosen the screws under the saw table to make the adjustment (mitre slot must be parallel to the saw blade). Once square, retighten screws.

ADJUSTING BLADE TENSION
See Figures 10-11.

• Switch off the saw.
• 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.
• Pluck the back straight edge of the saw blade like a guitar string while turning the tension knob.
• The sound becomes higher pitched as tension increases. 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.
• Too much tension may cause the blade to break. Thicker workpieces require higher tension; maximum tension is not needed for all cuts. Too little tension may cause the blade to slip on the wheels.

TRACKING THE BLADE
See Figure 11.

• Adjust blade tension properly before making tracking adjustments. Check that blade guides do not interfere with the blade. Blade gullet (the deepest part of the blade tooth) should be in the centre of the tire.

To adjust:

• Disconnect from power. Open the front covers by unscrewing the cover locking screw. Watch the blade’s position on the upper tire as, by hand, you slowly turn the upper wheel clockwise.
• If the blade moves away from the centre of the tire, the tracking must be adjusted.

If the blade has moved left or right of center:

• Turn the blade tracking knob (clockwise if blade has moved left; counterclockwise if blade has moved right) while turning the wheel by hand until the blade moves back and rides in the centre of the tire.
• Check the position of the blade on the lower tire. The blade should be completely on the tire (gullet of the blade teeth in the centre). 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 covers and tighten cover locking screw.
• Switch on the saw.
• Verify saw blade is centred on the tire (through the tracking view window). If not centred, repeat above steps.
• 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 and Thrust Bearings procedures explained in the “Adjustment” section of this operator’s manual.

INSTALLING THE RIP FENCE

• Place the rip fence on the left side of the saw table, with the lock handle at the front.
• Push down the lock handle to lock the position of the rip fence.
• Turn the lock handle to adjust tightness of the clamps.

OPERATION

• Do not allow familiarity with the product to make you careless. Remember that a careless fraction of a second is sufficient to inflict serious injury.
• Always wear eye protection. Failure to do so could result in objects being thrown into your eyes, resulting in possible serious injury.
• Do not use any attachments or accessories not recommended by the manufacturer of this product. The use of attachments or accessories not recommended can result in serious personal injury.
• To avoid blade contact, adjust the blade guide assembly to just clear the workpiece. Failure to do so could result in serious personal injury.
• Never operate saw without the blade guard secured and the front covers locked. To do so could result in serious personal injury.

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, mitring, 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.
Before starting a cut, watch the saw run. If you experience excessive vibration or unusual noise, stop immediately. Turn the saw off 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 6.35 mm (1/4”) wide blade will cut a minimum diameter of 38 mm (1-1/2”).
• 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.
• 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:
• Switch off the saw. Wait until the saw has come to a full and complete stop. 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.
• Switch off the saw. Wait until the saw has come to a full and complete stop.
• 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.
• Switch off the saw 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 devices, 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 mitre gauge.
• Before removing loose pieces from the saw table, switch off the saw and wait for all moving parts to stop.

• The miter gauge can be set to 60° maximum to the right or left.
• Loosen the lock knob on the miter gauge.
• With the miter gauge in the miter gauge slot, rotate the gauge until the desired angle is reached on the index scale.
• Retighten the lock knob.

Using the rip fence

• The rip fence is used for all ripping operations. Never rip freehand without the fence in place and securely locked.
• Position the fence to the desired width of the rip and lock it in place.
• Before starting to rip, be sure the rip fence is parallel to the saw blade. When ripping long boards or large panels, always use work support.
• Hold the piece against the fence and feed it through the saw blade with smooth, steady pressure.

ADJUSTMENTS

• Before performing any adjustment, make sure the tool is unplugged from the power supply and the switch is in the off position. Failure to heed this warning could result in serious personal injury.
• To avoid personal injury, maintain proper adjustment of blade tension, blade tracking, blade guides, and thrust bearings.

INSTALLING AND ADJUSTING THE BLADE
See Figure 17.

• Loosen and remove the wing screw, washers, and D- nut from the saw table.
• Open the front covers by unscrewing the cover locking screw.
• Turn the lock knob counterclockwise to unlock the blade guide assembly. Turning the blade guide knob (clockwise raises the blade guide assembly; counterclockwise lowers it), position the blade guide assembly about halfway between the saw table and saw housing. Retighten the lock knob.
• Open the blade guard by pulling the left side of the guard out and away from the wheel.
• Release all blade tension from the blade.
• Carefully remove the old blade.
• Wearing gloves, carefully uncoil the new blade at arms length. If the new blade was oiled to prevent rusting, it may need to be wiped to keep the oil from your workpiece. Carefully wipe in the same direction the teeth are pointing so the rag does not catch on the teeth of the saw blade.
• NOTE: The blade may need to be turned inside out if the teeth are pointing in the wrong direction. Hold the blade with both hands and rotate it inward.
• With the teeth of the blade toward the left of the saw and facing downward, place the blade through the lower blade guides and around both wheels.
• Slowly turn the upper wheel to the right or clockwise by hand to centre the blade on the rubber tires.
• Re-engage the RapidSet™ blade tension lever then adjust the blade tension; check or adjust the blade tracking.
• Adjust both upper and lower blade guides and thrust bearings as explained later in this Operator’s Manual.
• Reattach the wing screw, washers, and D-nut. Tighten securely.
• Close the blade guard and front cover. Tighten the cover locking screw.

ADJUSTING BLADE GUIDE ASSEMBLY
See Figures 18 – 19.

• To prevent the blade from twisting or breaking, the blade guide assembly should always be set approximately 3.2 mm (1/8”) above the workpiece.
• Turn the lock knob counterclockwise to unlock the blade guide assembly.
• As a guide, use a scrap piece of the same wood you are about to cut to set the height of the blade guide assembly. Adjust the blade guide assembly by turning the blade guide knob.
• Lock blade guide assembly in place by turning the lock knob clockwise.
• Always lock the blade guide assembly in place before turning on the band saw.

ADJUSTING BLADE GUIDE SUPPORT AND THRUST BEARINGS
See Figures 20 – 21.

• NOTE: Tighten the lock knob and refer to Adjusting Blade Tension and Tracking the Blade procedures explained in the ASSEMBLY section of this operator’s manual prior to making adjustments.
• The upper and lower blade thrust bearings support and bearing guides the saw blade during cutting operations. The adjustment of the bearings and guides should be checked whenever a different blade is installed.
• To adjust thrust bearings:
• The thrust bearings support the back edge of the blade during cutting. The blade should not contact the thrust bearings when you stop cutting. It is important that both upper and lower thrust bearings be adjusted equally.
• Open the front covers and blade guard.
• Using a hex key, loosen the upper and lower thrust bearing screws and push thrust bearings to the back of the saw.
• Verify that saw blade is tracking correctly, then slide the thrust bearing forward until the bearing is within 0.4 mm (1/64”) of the blade. Tighten the thrust bearing screw securely.
• Slide lower bearing forward until it has proper clearance. Tighten the thrust bearing screw securely.

To adjust blade guide support:

• Loosen the blade guide support and blade guide set screws using hex keys.

MAINTENANCE

• When servicing, use only identical replacement parts. Use of any other parts can create a hazard or cause product damage.
• Always wear eye protection during product operation. If operation is dusty, also wear a dust mask.
• Before performing any maintenance, make sure the tool is unplugged from the power supply and the switch is in the off position. Failure to heed this warning could result in serious personal injury.

GENERAL MAINTENANCE

• Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, oil, grease, etc.
• Do not at any time let brake fluids, gasoline, petroleum-based products, penetrating oils, etc., come in contact with plastic parts. Chemicals can damage, weaken or destroy plastic which may result in serious personal injury.
• Keep your band saw clean.
• Remove sawdust from the inside frequently.
• Do not allow pitch to accumulate on the saw table, blade guides, or thrust bearings. Clean them with gum and pitch remover.
• Apply a thin coat of automobile type wax to the saw table’s top so the wood slides easily while cutting.

Lubrication

• All of the bearings in this tool are lubricated with a sufficient amount of high grade lubricant for the life of the unit under normal operating conditions. Therefore, no further lubrication is required.

TIRES Cleaning tires:

• Pitch and sawdust accumulates on tires and needs to be removed with a fine wire brush or a piece of wood. Do not use a sharp knife or any kind of solvent.

Replacing tires:

• Open front cover and remove saw blade. See section on Installing and Adjusting the Blade.
• Pry the worn tire away from the wheel carefully.
• Stretch the new tire around the wheel.
• Replace the saw blade and close the front cover.

BRUSH
See Figure 22.

• There is a brush located inside the saw housing next to the wheel. It helps protect the tire and wheel by brushing off saw dust. As the brush becomes worn, it will need to be adjusted or replaced.
• Remove the screw and washer then pull the brush off.
• Place the new brush in the groove.
• Reinstall using the washer and screw.
