SAFETY GUIDELINES / DEFINITIONS This manual contains information that is important for you to know and understand. This information relates to protecting YOUR SAFETY and PREVENTING EQUIPMENT PROBLEMS. To help you recognize this information, we use the symbols to the right. Please read the manual and pay attention to these sections. Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
17. REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure switch is in “OFF” position before plugging in power cord. In the event of a power failure, move switch to the “OFF” position. 18. NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or if the cutting tool is accidentally contacted. 19. CHECK DAMAGED PARTS.
POWER CONNECTIONS A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3prong grounding type plugs and matching receptacle which will accept the machine’s plug.
EXTENSION CORDS Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire extension cord which has a 3-prong grounding type plug and matching receptacle which will accept the machine’s plug. When using an extension cord, be sure to use one heavy enough to carry the current of the machine. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Fig. D, shows the correct gauge to use depending on the cord length.

ASSEMBLY FOR YOUR OWN SAFETY, DO NOT CONNECT THE MACHINE TO THE POWER SOURCE UNTIL THE MACHINE IS COMPLETELY ASSEMBLED AND YOU READ AND UNDERSTAND THE ENTIRE INSTRUCTION MANUAL. STAND 1. Assemble stand as shown in Fig. 3, using parts shown in Fig. 2. The braces, legs and feet are numbered the same in both illustrations. Insert the M8x1.25x16mm carriage head screws through legs and braces then place the 3/8" flat washers on the screws and secure with the M8x1.25 hex nuts.
3. Place a M8.4 flat washer onto a M8x1.25x45mm hex head screw. Insert the screw through the hole (D) Fig. 6, in the stand and thread screw into the tapped hole in the band saw and tighten securely. Repeat this process for the remaining hole in stand and threaded hole in the band saw and tighten securely. D 4. Align the remaining two holes (A) Fig. 4, with the two holes in the stand. Place a M8.4 flat washer (H) Fig. 7, on a M8x1.25x45mm hex head screw.
4. Place a M6.4 flat washer (B) Fig. 10, onto a M6x1x30mm cheese head screw (A), and insert screw slot in table. Thread a M6x1 wing nut (C) Fig. 10, onto the screw and tighten securely. A B C Fig. 10 UPPER BLADE GUIDE ASSEMBLY C B Fasten the upper blade guide assembly (A) Fig. 11, to the side of the band saw using the lock plate (B) and lock screw (C) as shown. A Fig. 11 OPERATING CONTROLS AND ADJUSTMENTS STARTING AND STOPPING SAW The switch (A) Fig. 13, is located on the front side of the band saw.
OPENING AND CLOSING HINGED DOOR A C When making adjustments such as changing the blade, tracking the blade, blade guide adjustments, etc., the hinged doors (A) and (B) Figs. 15 and 16, can be opened as follows: B NEVER OPEN THE HINGED DOOR WHEN THE MACHINE IS RUNNING. D 1. Pull out on the two door knobs (C) and (D) Fig. 15, and swing doors (A) and (B) open. Fig. 15 2. Fig. 16, illustrates doors (A) and (B) in the open position. 3. To close and fasten doors (A) and (B), Figs.
TRACKING THE BLADE A For accurate work and maximum blade life, it is important that the blade (A) Fig. 18, be centered on the upper band saw wheel. When this adjustment is properly made, the blade will “track” – that is, it will run steady in the same line. To “track” the blade, proceed as follows: B DISCONNECT MACHINE FROM POWER SOURCE. Fig. 18 1. Make sure the blade is tensioned properly.
ADJUSTING UPPER BLADE GUIDES AND BLADE SUPPORT BEARING A J The blade guides must be properly adjusted to prevent the blade from twisting during operation. The upper blade guides and blade support bearing should be adjusted only after the blade is tensioned and tracking properly. To adjust, proceed as follows: G H G DISCONNECT MACHINE FROM POWER SOURCE. Fig. 21 1. Loosen screw (A) Fig. 21, and remove blade guard (B) from guide assembly. 2. The upper guide bracket (C) Fig.
2. The lower blade guides are held in the guide bracket with set screws (D) Fig. 24. Loosen set screws (D) and adjust blade guides as close as possible to the sides of the saw blade, being careful not to pinch the saw blade. Then tighten set screws (D). D 3. The lower blade support bearing (E) Fig. 24, prevents the blade from being pushed back too far while cutting which could damage the set in the saw teeth.
MAINTENANCE ADJUSTING BELT TENSION B If the drive belt on your band saw is slipping, check and adjust as follows: DISCONNECT MACHINE FROM POWER SOURCE. A 1. Remove screw (A) Fig. 29, and belt and pulley cover (B). 2. A poly V-belt (C) Fig. 30, drives the saw pulley (D) from the motor pulley (E). Correct tension of the belt (C) is when there is approximately 1/4" deflection in the center span of the belt (C) using light finger pressure.
DUST CHUTE A dust chute (A) Fig. 33, is provided which enables you to connect your band saw to a standard shop vacuum or dust collector. The opening of the dust chute is 2-1/4" I.D. A Fig. 33 OPERATING THE BAND SAW Before starting the machine, insure that all adjustments are properly made and the guards are in place. Turn the upper wheel by hand to make sure that everything is correct BEFORE turning on the power. Keep the top guide within 1/8" of the work piece at all times.
TROUBLESHOOTING GUIDE In spite of how well a band saw is maintained, problems can occur. The following troubleshooting guide will help you solve the more common problems: Trouble: SAW WILL NOT START. Probable Cause Remedy 1. Saw not plugged in. 1. Plug in saw. 2. Fuse blown or circuit breaker tripped. 2. Replace fuse or reset circuit breaker. 3. Cord damaged. 3. Have cord replaced. Trouble: BREAKER KICKS OUT FREQUENTLY. Probable Cause Remedy 1. Improper extension cord. 1.
TROUBLESHOOTING GUIDE (CONTINUED) Trouble: BLADE WILL NOT TRACK. Probable Cause Remedy 1. Blade too loose 1. Adjust tension 2. Upper wheel not properly adjusted. 2. Adjust upper wheel. 3. Improperly adjusted blade support bearing. 3. Adjust blade support bearing. Trouble: CUT DOES NOT AGREE WITH SETTING ON THE TILT SCALE. Probable Cause Remedy 1. Pointer out of adjustment 1. Adjust pointer. Trouble: BLADE WILL NOT STAY ON WHEEL. Probable Cause Remedy 1. Blade not tensioned properly. 1.
BAND SAW BLADES A band saw blade is a delicate piece of steel that is subjected to tremendous strain. You can obtain long use from a band saw blade if you use it properly. Be sure you use blades of the proper thickness, width and temper for the various types of material and cuts. Always use the widest blade possible. Use narrow blades only for sawing small, abrupt curves and for fine, delicate work. This will save blades and will produce better cuts.
