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.
B. USE OF MACHINE: (1). REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that 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).
(3). KEEP CHILEREN AND VISITIORS AWAY. All children and visitors should be kept a safe distance from work area. (4). DON’T install & use this machine in explosive, dangerous environment. E. MAINTENANCE: (1). DISCONNECT machine from power source when making repairs. (2). CHECK DAMAGED PARTS.

TRANSPORTATION OF MACHINE: Unpacking 1.
(1). Tighten all locks before operation. (2). ALWAYS Keep proper footing & balance while moving this 125kgs machine, and only use heavy duty fiber belt to lift the machine as Fig. A (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 repeats the running Test. (5).
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 Enter 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 Vary-Tooth) when using a cutting fluid. Increase Band Speed: 15% When cutting 1/4"(6.

Monitor chip information and adjust feed accordingly.
6. ASSEMBLY A 3/4 HP, motor, split phase or capacitor-start it recommended for best economical performance. Counterclockwise rotation is required. Note that rotation can be reversed by following directions On the 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 vertical 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. (4).
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 (FOR CE ONLY) 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. Start the motor, allow the saw to come to full speed, then begin the cut by letting the head down slowly onto the work. DO NOT DROP OR FORCE.
CHANGING BLADE Raise saw head to vertical 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 (1). Loosen the A. B. C. D. Screw. (2). Adjust rear vise to the threaded hole position. (E) (3). Set the scale to the desired angle. (4). Adjust the front vise (F) to parallel the rear vise(E) (5). Tighten the A. B. C. D. Screw. 8. BLADE GUIDE BEARING ADJUSTMENT ATTENTION: This is the most important adjustment on your saw. It is impossible to get satisfactory work from your saw if the blade guides are not properly adjusted. The blade guide bearings on your metal.
REMARK: 1. Adjust the tension of blade until the back of the blade(A) against the blade wheel (front) lightly. 2. Be sure the nut (E) is tightened. 3. Turn the eccentric shaft(B) counterclockwise, when the bearing(D) touches the saw blade properly, tighten the nut(E). 4. To adjust, loosen set screw(F) and move the blade adjustable up or down until it lightly Touches the back of the blade(A). 5. Repeat 1. 2, 3, and 4 steps to adjust the other side's blade guide bearings(G). 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.
(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. (2) Weekly Maintenance (a) Clean and coat the leading screw with oil. (b) Check to see if sliding surface and turning parts lack of lubricant. If the lubricant is insufficient, fill it. (3) Monthly Maintenance (a) Check if the fixed portion has been loose.
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 4. Material too coarse teeth spacing blade 4. Use a blade of slow speed 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.
Blade. 2. Too heavy pressure; too slow speed. 2. Decrease pressure, increase speed 3. Vibrating work-piece. 4. Gullets loading 3. Clamp work piece securely 4. Use coarser tooth blade or brush to remove chips. Motor running too hot 1. Blade tension too high. 1. Reduce tension on blade. 2. Drive belt tension too high. 2. Reduce tension on drive 3. Blade is too coarse for work Bad Cuts (Crooked) 4. Blade is too fine for work 5. Gears aligned improperly 3. Use finer blade. 4. Use coarse blade. 6.
