Grounding Instructions 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.
The 115V attachment plug (shown in Figure 6) supplied with the band saw, must be replaced with a UL/CSA listed plug suitable for 230V operation (shown in Figure 7). Contact your local authorized Walter Meier (Manufacturing) Inc., service center or qualified electrician for proper procedures to install the plug. The band saw must comply with all local and national codes after the 230 volt plug is installed.
Unpacking The band saw is shipped in two cartons. Open both cartons and inspect contents for shipping damage. Report any damage immediately to your distributor and shipping agent. Do not discard any shipping material until the Band Saw is assembled and running properly. Compare the contents of both cartons and all internal boxes with the following parts list to make sure all parts are intact.(*) Missing parts, if any, should be reported to your distributor.

Installation and Assembly Tools required for assembly: open-end or box wrenches– 10mm, 12mm, 1/2” [in some cases, a socket wrench set can be used to speed assembly time] hex (Allen) wrenches – 3, 5, 6mm Cross point (Phillips) screwdriver square straightedge NOTE: If further clarification is needed for any of the following assembly procedures, consult the exploded views at the back of this manual. Exposed metal surfaces on the Band Saw, such as the table, have been given a protective coating at the factory.
5. Push motor cord and strain relief plate through the opening to the outside of the stand, as shown in Figure 16. Fasten the strain relief plate to the stand with two M5x12 pan head screws (HP3-G). 6. Connect the plugs of the switch cord and motor cord (Figure 16). Do not connect machine to power source during assembly. Installing Drive Belt Figure 17 Refer to Figures 17 through 20. 1. The motor and wheel pulleys have been accurately aligned with each other by the manufacturer.
Installing Trunnion Support Refer to Figure 21. 1. Use the two locating pins attached to the saw body to help position the trunnion support. Attach trunnion support to saw body with two M8x30 hex cap screws (HP1J) and two M8 lock washers (HP1-F). Tighten with a 1/2” wrench. 2. Thread M8 hex nut (HP1-H) onto the M8x80 hex cap screw (HP1-K) and install into the trunnion support as shown. Finger tighten the hex nut; this will be fully tightened later for the 90° table stop setting.
Leveling the Extension Table NOTE: Before leveling the extension table, the 90-degree stop of the main table should be verified. Read “Adjusting 90° Table Stop” on page 20, then return to this page. Refer to Figures 22 and 24. 1. Position the main table at 90-degrees and tighten the table locking knobs. 2. Place a straight edge (Figure 24) across both tables, at several points along the tables. If the extension table is not level with the main table, use the level board beneath to achieve this, as follows.
4. Shift either end of the fence as needed to gain identical distance from table top. 5. Tighten both screws in the rear rail using a 10mm wrench. Installing Front Rail and Rip Fence Refer to Figures 26 through 29. 1. Install front rail (E, Figure 26) to the main table using two M6x20 hex cap screws (HP4-L), two 1/4" lock washers (HP4-M) and two 1/4" flat washers (HP4-N). Finger tighten only at this time. Figure 27 2.
Aligning Fence to Blade Refer to Figure 31. 1. Place the table at 90-degrees. (Make sure the 90° Table Stop setting has been verified – see page 20.) 2. Lock the fence to the guide rail with the handle. 3. Place a square on the table and against the fence, as shown in Figure 31. 4. If the fence is not square to the table, slightly loosen the two screws in the front rail (see Figure 26) and raise or lower one end of the front rail assembly until fence is square to table. Figure 31 5. Re-tighten screws.
Resaw Guide Refer to Figure 32. For resawing operations, attach the resaw guide (HP4-A) to the fence using the knob (HP4-B) through the slotted hole. Position the resaw guide so that it is centered approximately with the front edge of the saw blade. The resaw guide offers a taller, single-point contact surface that allows pivoting of the workpiece in order to keep the blade on the cutting line. Blower Nozzle Figure 32 Refer to Figures 33 and 34. 1.
Installing Quick Tension Lever Refer to Figure 36. Install the quick tension lever (M) onto the shaft as shown, and tighten the two set screws using a 3mm hex wrench. The movement of the blade tension lever is explained under “Installing Blades”. Stand Attachments Refer to Figure 37. 1. Mount the two miter gauge hooks (HP3-B) to the side of the stand with two M8x16 carriage bolts (HP3-E) and two M8 flanged hex nuts (HP3-F). Position the hooks at an angle, similar to that shown in Figure 38.
Adjustments Tilting the Table Unplug the machine from the power source before making any repair or adjustment. Refer to Figure 39. 1. Loosen the table locking knobs. 2. Tilt table up to 45 degrees to the right. The angle is indicated on the trunnion scale. Figure 39 3. Tighten the table locking knobs. 4. You can place a measuring device on the table and against the blade to verify the 45° setting. Adjusting 90° Table Stop Refer to Figures 39 and 40. 1. Disconnect machine from power source. 2.
Table Aligned with Blade For accurate crosscuts using the miter gauge, the table (i.e. miter slot) must be aligned with the blade. This alignment has been set by the manufacturer, but the operator may wish to verify it, as follows. NOTE: This procedure works best with a wide blade. Refer to Figure 41. 1. Place a straightedge along the side of the blade, with very light pressure (do not deflect the blade). The straightedge should contact both front and back of blade. Figure 41 2.
6. Remove the current blade from the upper wheel, then the lower wheel. Turn blade to direct it through the slot in the table. New blades are usually packaged in coiled position. Use gloves and grasp the coil with one hand while slowly uncoiling the blade with the other hand. 7. Guide new blade through table slot. Place blade in upper and lower blade guides, and around upper and lower wheels. Note: Make sure blade teeth point forward and down toward the table.
Blade Tracking Disconnect machine from power source. Do not adjust blade tracking with the machine running. “Tracking” refers to how the blade is positioned on the wheels while in motion. The blade should track approximately in the center of both wheels, as shown in Figure 44. Tracking on the PWBS14CS Band Saw has been factory-adjusted; however, it should be checked periodically, including after every blade change. Figure 44 Refer to Figure 45. 1.
2. Loosen lock knob and raise or lower upper blade guide assembly to approximately 3/16” above the material being cut. 3. Tighten lock knob. 4. The guide post (Figure 46) is spring loaded. To adjust the tension on the spring, unscrew and completely remove knob, then tighten or loosen set screw, until desired tension is reached. Re-install knob. Upper Bearing Guides Refer to Figures 47, 48, 49. 1. Disconnect machine from power source. Figure 47 2. Blade must already be tensioned and tracking properly. 3.
2. Blade must already be tensioned and tracking properly. 3. Loosen thumb screw (J) and move guide block by turning knob (K) so that the front of the guide wheels (L) are just behind the gullet (curved area at base of tooth) of the blade. 4. Tighten thumb screw (J). Thrust Bearing 5. Loosen thumb screw (M) and turn knob (N) to move the support bearing (O) in or out until the bearing is approximately 0.016” (or 1/64") behind the blade.
On/Off Switch The band saw is equipped with a push-button switch that will accept a safety padlock (not included). To safeguard your machine from unauthorized operation and accidental starting by young children, the use of a padlock is highly recommended – see Figure 54. Maintenance Before doing maintenance, disconnect machine from electrical supply by pulling out the plug or switching off the main switch! Failure to comply may cause serious injury.
A fine pitch (more teeth per inch) will cut slowly but more smoothly. A coarse pitch (fewer teeth per inch) will cut faster but more roughly. Blade Selection Using the proper blade for the job will increase the operating efficiency of your band saw, help reduce necessary saw maintenance, and improve your productivity. Thus, it is important to follow certain guidelines when selecting a saw blade. As a rule of thumb, the thicker the workpiece, the coarser will be the blade pitch.
Set Blade Breakage The term “set” refers to the way in which the saw teeth are bent or positioned. Bending the teeth creates a kerf that is wider than the back of the blade. This helps the operator more easily pivot a workpiece through curve cuts, and decreases friction between blade and workpiece on straight cuts. Band saw blades are subject to high stresses and breakage may sometimes be unavoidable. However, many factors can be controlled to help prevent most blade breakage.
Ripping Operation Ripping is cutting lengthwise down the workpiece, and with the grain (of wood stock). See Figure 58. Always use a push stick or similar safety device when ripping narrow pieces. The following section contains basic information, and is not intended to cover all possible applications or techniques using the Band Saw. Consult published sources of information, acquire formal training, and/or talk to experienced Band Saw users to gain proficiency and knowledge of band saw operations.
Resawing It is more common with small, narrow blades, and is almost always attributable to poor blade quality, or lack of proper adjustments. Inspect the band saw for the following: Resawing is the process of slicing stock to reduce its thickness, or to produce boards that are thinner than the original workpiece, such as veneers. • • • • The ideal blade for resawing is the widest one the machine can handle, as the wider the blade the better it can hold a straight line.
Troubleshooting – Mechanical and Electrical Problems Trouble Machine will not start/restart or repeatedly trips circuit breaker or blows fuses. Band Saw does not come up to speed. Probable Cause Remedy No incoming power. Verify machine is connected to power source. Electrical cord damaged. Replace cord. Building circuit breaker trips or fuse blows. Verify that band saw is on a circuit of correct size. If circuit size is correct, there is probably a loose electrical lead.
Troubleshooting – Operating Problems Trouble Probable Cause Remedy Table tilt does not hold position under load. Table locking knobs are not tight. Tighten locking knobs . Table will not tilt. Trunnion is not lubricated. Grease the trunnion. Trunnion is jammed. Disassemble and replace jammed parts. Stand is on uneven floor. Re-position on flat, level surface. Drive belt is too slack, or worn. Increase tension on drive belt. Replace belt if worn.
Trouble “Blade lead” occurs (blade wanders during cut) Blade cannot be tensioned properly. Blade binds in the workpiece. Blade forms cracks at base of teeth. Cracks on back edge of blade. Blade breaks prematurely. Probable Cause Remedy Fence not aligned with blade. Check and adjust fence (see page 17) Wood is warped. Select different wood. Excessive feed rate Reduce feed rate. Incorrect blade being used for the particular cut being made. Change blade to correct type.
Trouble Blade breaks close to weld. Premature dulling of saw teeth. Probable Cause Remedy Blade cooled too rapidly after welding. Replace blade, or have blade annealed, or eliminate brittle part and weld correctly. Thrust bearing not properly supporting blade, or guide post/side bearings set too high allowing flex. Check all guide bearings for correct position and signs of wear. Adjust or replace as needed. Blade tensioned too tightly. Reduce tension (see page 22).
Blade Selection Guide Identify the material and thickness of your workpiece. The chart will show the recommended PITCH, blade TYPE, and FEED RATE. Key: H – Hook S – Skip R – Regular L – Low M – Medium H – High Example: 10/H/M means 10 teeth per inch / Hook Type Blade / Medium Feed For Radius Cutting Study the part drawing or prototype, or actually measure the smallest cutting radius required, and locate this radius (in inches) on the chart at the right.
