RULES FOR SAFE OPERATION The purpose of safety symbols is to attract your attention to possible dangers. The safety symbols, and the explanations with them, deserve your careful attention and understanding. The safety warnings do not by themselves eliminate any danger. The instructions or warnings they give are not substitutes for proper accident prevention measures. Symbol Meaning DANGER: Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
RULES FOR SAFE OPERATION Safe operation of this power tool requires that you read and understand this operator's manual and all labels affixed to the tool. Safety is a combination of common sense, staying alert, and knowing how your band saw works. READ ALL INSTRUCTIONS KNOW YOUR POWER TOOL. Read the operator's manual carefully. Learn the applications and limitations as well as specific potential hazards related to this tool.
RULES FOR SAFE OPERATION AVOID AWKWARD OPERATIONS AND HAND POSITIONS where a sudden slip could cause your hand to move into the blade. ALWAYS make sure you have good balance. ALLOW THE MOTOR TO COME UP TO FULL SPEED before starting a cut to avoid binding or stalling. DO NOT USE TOOL IF SWITCH DOES NOT TURN IT ON AND OFF. Have defective switches replaced by an authorized service center. REPLACEMENT PARTS.
ELECTRICAL EXTENSION CORDS ELECTRICAL CONNECTION Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool'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 tool 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.

ASSEMBLY 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.
ASSEMBLY Align the screw holes in the saw table with the holes in the saw table bracket. Using the phillips screws, attach the saw table to the saw table bracket. Tighten phillips screws securely. Attach the table aligning bolt, washer, and wing nut to the saw table. NOTE: The wing nut goes below the saw table. LOCK KNOB TABLE ALIGNING BOLT SQUARING THE SAW TABLE TO THE BLADE See Figure 8.
ASSEMBLY ADJUSTING BLADE TENSION See Figures 9 and 10. Turn off and unplug the saw. Remove the switch key. WARNING: Failure to turn the saw off, remove the switch key, and unplug the saw could result in accidental starting causing possible serious personal injury. Before using the band saw, turn the blade tension knob on the top of the saw clockwise to engage tension. See Figure 9. NOTE: Adjustments of blade tension can be made at anytime.
ASSEMBLY ATTACHING THE WORKLIGHT WORKLIGHT BRACKET See Figure 11.

ADJUSTMENTS Slowly turn the upper wheel to the right or clockwise by hand to center the blade on the rubber tires. Adjust the blade tension; check or adjust the blade tracking and re-engage the RapidSet™blade tension lever. Adjust both upper and lower blade guides and thrust bearings. Reattach the aligning bolt, washer, and wing nut. Tighten securely. Reattach the blade guard. Close front cover.
ADJUSTMENTS ADJUSTING THRUST BEARINGS, BLADE GUIDE SUPPORT, AND BLADE GUIDES See Figures 20 - 22. The upper and lower blade guides and thrust bearings support the band saw blade during cutting operations. The adjustment of the guides and bearings should be checked whenever a different blade is installed. NOTE: The lower blade guide support screw is the top screw located on the right of the saw housing under the table. See Figure 21. WARNING: Never operate saw without blade guard secured in place.
ADJUSTMENTS To Adjust Blade Guides: BLADE GUIDE ASSEMBLY The blade guides help keep the blade from twisting and binding. The blade will be ruined if the blade teeth hit the blade guides while using the band saw. The set of teeth and the sharpened edge of teeth will be damaged by hitting the blade guides. Proper adjustment of the upper and lower blade guides will prevent this from happening. Remove the blade guard by loosening the two phillips screws.
MAINTENANCE LUBRICATION All 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. Remove the nut and washer from the middle of the saw housing. See Figure 24. Pull the lower wheel away from the saw housing. Remove the worn drive belt. Place new drive belt on the pulley.
TROUBLESHOOTING WARNING: To prevent accidental starting that could cause possible serious personal injury, turn off the saw, remove the switch key, and unplug the saw from the power source before working on the band saw. PROBLEM CAUSE SOLUTION Motor will not run. 1. Problem with On-Off switch or power cord. 2. Motor defective. 1. Have worn parts replaced before using band saw again. 2. Do not attempt any repair. Have tool repaired by a qualified service technician.

OPERATOR'S MANUAL 9 in. (229 mm) Band Saw BS902 EXTENSION CORD CAUTION **Ampere rating When using a power tool at a considerable distance from a power source, be sure to use an extension cord that has the capacity to handle the current the tool will draw. An undersized cord will cause a drop in line voltage, resulting in overheating and loss of power. Use the chart to determine the minimum wire size required in an extension cord. Only round jacketed cords should be used.
