General safety rules Safety is a combination of common sense, staying alert and knowing how your band saw works. SAVE THESE SAFETY INSTRUCTIONS. WARNING: To avoid mistakes that could cause serious injury, do not plug in the band saw until the following steps have been read and understood. 1. READ and become familiar with this entire instruction manual. LEARN the tool’s applications, limitations, and possible hazards. 2. AVOID DANGEROUS CONDITIONS.
13. NEVER LEAVE A RUNNING TOOL UNATTENDED. Turn the power switch to OFF. Do not leave the tool until it has come to a complete stop. 14. NEVER STAND ON A TOOL. Serious injury could result if the tool tips or is accidentally hit. DO NOT store anything above or near the tool. 15. DO NOT OVERREACH. Keep proper footing and balance at all times. Wear oilresistantrubber-soled footwear. Keep the floor clear of oil, scrap, and other debris. 16. MAINTAIN TOOLS PROPERLY.
Specific safety rules for band saws 1. To avoid injury from unexpected movement, make sure the saw is on a firm, level surfaceand secured properly to prevent rocking. Make sure there is adequate space for operations. Bolt the saw to a support surface to prevent slipping or sliding during operation. 2. Turn off and unplug the saw before moving it. 3. Use the correct size and style of blade. 4. Make sure the blade teeth point down and toward the table. 5.
16. Don’t leave the work area until all moving parts have stopped. Shut off the power to master switches. Remove the switch key from the band saw and store it in a safe place away from children. Childproof the workshop! Electrical information Grounding Instructions IN THE EVENT OF A MALFUNCTION OR BREAKDOWN, grounding provides the path of least resistance for electric current and reduces the risk of electric shock.
Guidelines for Using Extension Cords Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The table below shows the correct size to be used according to cord length and nameplate ampere rating. When in doubt, use a smaller-numbered gauge (the smaller the gauge number, the heavier the cord).

Assembly CAUTION: Do not attempt assembly if parts are missing.Use this manual to order replacement parts. WARNING: To avoid injury, do not attempt to run oruse this machine until all parts are assembled and workingproperly. Assembly stand Note: Hand-tighten all hardware during assembly. Do notcompletely tighten hardware until assembly is complete. Refer to Exploded View and Parts List, Page 26. 1. Place base (Item 6) on flat surface.
Centering the table 1. Loosen the hex bolts mounting the trunnion to the saw frame (see Figure 1). 2. Move the table sideways as required, until the saw blade runs through the center of the table insert. 3. Re-tighten hex bolts for trunnion and recheck the saw blade position. Setting table square to saw blade Refer to Figures 1 and 2. Loosen the handle on the table trunnion and place asuitably sized square against the saw blade. If the tablerequires adjustment, proceed as follows: 1.

Changing and adjusting the saw blade This band saw is factory-equipped with a general-purpose,woodcutting blade; the saw blade is set prior to delivery. To change the saw blade, follow the procedure below: WARNING: To avoid injury from unexpected starting,whenever changing the saw blade or carrying outadjustments, switch the band saw off and remove thepower cord from the main outlet. To avoid injury tohands when handling the saw blade, wear gloveswhenever necessary. Blade Figure 7 1.
Setting the cutting height 1. The upper blade guide should be set as close as is practically necessary against the workpiece. 2. To adjust this height, loosen the locking knob in the center of the adjusting knob (See Figure 8). 3. Set the blade guide to the required height by turning the guidepost-adjusting knob. 4. Tighten locking knob after setting. GuidepostAdjusting Knob Locking Knob Figure 8 Adjusting the blade guides NOTE: Upper and lower blade guides are adjusted inthe same manner.
Adjusting the rip fence Fence Body The locking pressure of the rip fence has been factory-set. Figure 12 The fence handle has a cam action, press down thehandle to clamp tightly to the table after setting ripfence to desired position. Fence Extrusion NOTE: The rip fence can be used on both sides of theblade. The rip fence extrusion needs to be positioned onthe side of the fence body that is closest to the blade.
BLADE SELECTION 1. Blades vary depending on type of material, size of workpiece and type of cut that is being performed. 2. Characteristics which make blades different are width, thickness and pitch. BLADE WIDTH 1. Width of blade describes distance from tip of a tooth to back of blade. 2. Width of blade affects rigidity of blade. A wider blade wanders less and produces a straighter cut. 3. Width of blade also limits the smallest radius which can be cut. A 1⁄4″ wide blade can cut about a 1⁄2″ radius.
CONTOUR SAWING 1. When contour sawing, use both hands to keep workpiece flat against table and guided along desired path. 2. Avoid positioning hands in line with the blade. If hands slip, they may contact blade. 3. Try to stand in front of the saw. Place hands over the portion of the table to the right of the blade before cutting. 4. Cut small corners by sawing around them. Saw to remove scrap until desired shape is obtained. BEVEL CUTTING 1. 2. 3. 4.
Operation ON/OFF Switch(Figure 14) 1. To turn the saw ON, move the switch to the up (ON) position. 2. To turn the saw OFF, move the switch to the down (OFF) position. 3. To lock the switch in the OFF position: Figure 14 a) Wait until the band saw has come to a complete stop. b) Remove the switch key from the switch housing. Store the switch key in a safe place. 4. To unlock the switch and turn the saw ON, insert the switch key into the switch, and move the switch to the ON position.
Cutting Curves When cutting curves, carefully turn the work piece so the blade follows without twisting. If the curve is so sharp that you repeatedly back up and cut new kerf, use either a narrower blade or a blade with more set (teeth further apart). When a blade has more set, the work piece turns easier with a rougher cut. When changing a cut, do not withdraw the work piece from the blade. The blade may get drawn off the wheels.
