WARNING: FAILURE TO FOLLOW THESE RULES MAY RESULT IN SERIOUS PERSONAL INJURY As with all machinery there are certain hazards involved with operation and use of the machine. Using the machine with respect and caution will considerably lessen the possibility of personal injury. However, if normal safety precautions are overlooked or ignored, personal injury to the operator may result. This machine was designed for certain applications only.
keys and adjusting wrenches are removed from tool before turning it "on". (2). DON'T FORCE TOOL. It will do the job better and be safer at the rate for which it was designed. (3). USE RIGHT TOOL. Don't force tool or attachment to do a job for which it was not designed. (4). SECURE WORK. Use clamps or a vise to hold work when practical. It's safer than using your hand frees both hands to operate tool. (5). MAINTAIN TOOLS IN TOP CONDITION. Keep tools sharp and clean for best and safest performance.
E. MAINTENANCE: (1). DISCONNECT machine from power source when making repairs. (2). CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is damaged should be carefully checked to ensure that it will operate properly and perform its intended function check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced. (3).

(3). TURN OFF the power before wiring, & be sure machine in proper grounding, Overload & circuit breaker is recommended for safety wiring. (4). CHECK carefully if the saw blade is running in Counter-clockwise direction, if not reverse the Wiring per circuit diagram then repeat the running Test. (5). KEEP machine always out from sun, dust, wet, 912(B.G) raining area. 912(DR.GDR) 3. MINIMUM ROOM SPACE FOR MACHINE OPERATION 4.
TOOTH SELECTION You need to consider: 1. The width of the cut. That is, the distance in the cut that each tooth must travel from the point it Enters the work piece until it leaves the work piece, and 2.The shape of the work piece. Squares, Rectangles, Flats (Symbol : ) Locate the width of cut on the chart. (Inches on the outer circle and millimeters on the inner circle.) Select the tooth pitch on the ring marked with the square shape which aligns with the width of cut.
5. BI-METAL SPEEDS AND FEEDS These figures are a guide to cutting 4"(100mm) material (with a 314 Vari-Tooth) when using a cutting fluid. Increase Band Speed: 15% When cutting 1/4"(6.4mm) material (l0/l4 Vari-Tooth) 12% When cutting 3/4"(19 mm) material (6/10 Vari-Tooth) 10% When cutting 1-1/4"(32 mm) material (5/8 Vari-Tooth) 5% When cutting 2-1/2" (64 mm) material (4/6 Vari-Tooth) Decrease Band Speed: 12% When cutting 8"(200mm) material (2/3 Vari-Tooth) MATERIAL ALLOY BAND SPEED ASTM NO.

Monitor chip information and adjust feed accordingly.
6. ASSEMBLY A 1 HP, motor, split phase or capacitor-start it recommended for best economical performance. Counterclockwise rotation is required. Note that rotation can be reversed by allowing directions Given on terminal or nameplate. (1). Assemble the motor Mounting plate to the head using the long bolt Note that the flat side of the plate faces up. (2).
7. OPERATION WORK SET UP (1). Raise the saw head to the highest position. (2). Open vise to accept the Piece to be cut by rotating the wheel at the end the base. (3). Place work piece on saw bed. If the piece is long, support the end. (4). Clamp work pieced securely in vise. WORK STOP ADJUSTMENT (1). Loosen the thumb screw holding the work stop casting to the shaft. (2). Adjust the work stop casting to the desired length position. (3). Rotate the work stop to as close to the bottom of the cut as possible.
BLADE DIRECTION OF TRAVEL Be sure the Made is assembled to the pulleys such that the vertical edge engages the work piece first. BLADE MOVEMENT Blade Direction STARTING SAW Switch button function description (Emergency Push Button) (Start Button) (Stop Button) (Coolant Selection Switch) CAUIION: NEVER OPERATE SAW WITHOUT BLADE GUARDS IN PLACE. Be sure the blade is not in contact with the work when the motor is started.
are so far apart that they straddle the work, severe damage to the work piece and to the Made can result. CHANGING BLADE Raise saw head to the highest position and open the blade guards. Loosen tension screw knob sufficiently to allow the saw blade to slip off the wheels. Install the new blade with teeth slanting toward the motor as follows: (1). Place the blade in between each of the guide bearings. (2). Slip the blade around the motor pulley (bottom) with the left hand and hold in position. (3).
QUICK VISE ADJUSTMENT FOR ANGLE CUT (912DR.912GDR) (1). Pull out plastic knob (A).turn and lock the plastic knob. (2). Loosen grip (B).Then rotates the Body Frame for the desired angle. Be aware the blade Position is higher than the Vise Table by pulling up the Body Frame when counter-clockwise Rotation for miter cutting. And for clockwise rotation for angle cutting higher the Body Frame and keep the blade position higher than the vise. Then pull forward the vise Jaw Bracket (Front) to a proper location.
guides for proper spacing. NOTE: There should be from 000 (just touching) 001 clearance between the blade and guide bearings to obtain this clearance adjust as follows: 1. The inner guide bearing is fixed and cannot be adjusted. 2. The outer guide bearing is mounted to an eccentric bushing and can be adjusted. 3. Loosen the nut while holding the bolt with an Alien wrench. 4. Position the eccentric by turning the bolt to the desired position of clearance. 5. Tighten the nut. 6.
9. BLADE TRACK ADJUSTMENT (1). Open the blade guard. (2). Remove the blade guide assemblies (top and bottom) (3). Loosen the hex head screw in the tilting mechanism to a point where it is loose but snug. (4). with the machine running, adjust both the set crew and blade tension knob simultaneously to keep constant tension on the blade. The set screw and blade tension knob are always turned in opposite directions, i.e., when one is turned clockwise the other is turned counterclockwise.
(1) Daily Maintenance (by operator) (a) Fill the lubricant before starting machine everyday. (b) If the temperature of spindle caused over-heating or strange noise, stop machine immediately to cheek it for keeping accurate performance. (c) Keep work area clean; release vise, cutter, work-piece from table; switch off power source; take chip or dust away from machine and follow instructions lubrication or coating rust proof oil before leaving.
11. TROUBLE SHOOTING Symptom Possible Cause(s) Corrective Action Excessive Blade 1. Materials loosen in vise. 1. Clamp work securely Breakage 2. Incorrect speed or feed 3.Blade teeth spacing too large 2. Adjust speed or feed 3. Replace with a small teeth 4. Material too coarse spacing blade 4. Use a blade of slow speed and small teeth spacing 5. Incorrect blade tension 6.Teeth in contact with material before saw is started 7. Blade rubs on wheel flange 8. Miss-aligned guide bearings 9.
Motor running too hot speed. 3. Vibrating work-piece. speed 3. Clamp work piece securely 4. Gullets loading 4. Use coarser tooth blade or brush to remove chips. 1. Blade tension too high. 2. Drive belt tension too high. 1. Reduce tension on blade. 2. Reduce tension on drive belt. 3. Use finer blade. 3. Blade is too coarse for work 4. Blade is too fine for work 5. Gears aligned improperly 4. Use coarse blade. 5. Adjust gears so that worm is 6. Gears need lubrication in center of gear. 6.
