17 and 18, can be opened as follows: MOVING PARTS. LAZERATION / PINCH HAZARD: NEVER OPEN THE DOOR WHEN THE MACHINE IS RUNNING. 1. Press in the two locking latches (A) Fig. 17, and swing door (B) open. 2. Fig. 18, illustrates door (B) in open position. 3. To close and fasten door (B) Figs. 17 and 18, press on door directly over latches (A) Fig. 17, until latches snap into the locking position. 11 B A Fig. 17 B Fig. 18 ADJUSTING BLADE TENSION Blades of 1/8", 1/4", and 3/8" in width by 59-1/2" in length are available for use with your band saw. NOTE: The blade tension must be adjusted to accommodate different blade widths in order to provide proper blade tracking, cutting performance, and blade life. DISCONNECT MACHINE FROM POWER SOURCE. 1. After the desired blade is assembled to the two wheels, turn tension knob (A) Fig. 19, clockwise until spring (B) begins to compress. 2. Turn tension knob (A) Fig. 19, an additional 2-1/2 turns for 1/8" wide blades; 3 turns for 1/4" wide blades; and 4 turns for 3/8" wide blades. 3. A chart (C) Fig. 19, is located at the rear of the band saw. This chart shows blade size, and the minimum radius that can be cut with each size blade. TRACKING THE BLADE DISCONNECT MACHINE FROM POWER SOURCE. 1. Before tracking the blade, make sure the blade guides and blade support bearings are clear of the blade so as not to interfere with the tracking adjustment. Also make sure that the blade is tensioned properly. (Refer to section “ADJUSTING BLADE TENSION”). 2. Open the hinged door (C) Fig. 20. 3. Rotate upper wheel (A) Fig. 20, clockwise by hand and check to see if the blade (B) rides true on the approximate center of the two wheels. 4. If an adjustment is necessary, SLIGHTLY turn blade tracking knob (D) Fig. 19, clockwise to move the blade to the rear, and counterclockwise to move the blade to the front. NOTE: Turn the blade tracking knob (D) in small intervals to adjust the blade tracking. ADJUSTING UPPER BLADE GUIDE ASSEMBLY The upper blade guide assembly (A) Fig. 21, should always be no more than 1/8" above or as close as possible to the top surface of the workpiece being cut. Loosen knob (B) Fig. 21, rotate knob (C) and position the guide assembly (A) to the desired position. Then tighten knob (B). Fig. 19 D C B A A B C Fig. 20 A BC Fig. 21 12 ADJUSTING UPPER BLADE GUIDES AND BLADE SUPPORT BEARING IMPORTANT: BOTH THE UPPER AND LOWER BLADE GUIDES MUST BE PROPERLY ADJUSTED TO PREVENT THE BLADE FROM TWISTING DURING OPERATION. DISCONNECT MACHINE FROM POWER SOURCE. 1. NOTE: Upper blade guard (B) Fig. 22, is shown removed for clarity. 2. Loosen the two screws (C) Fig. 22, and adjust the blade guides (D) as close as possible to the sides of the saw blade, being careful not to pinch the blade.Then tighten the two screws (C). 3. Loosen screw (E) Fig. 22, and move the guide bracket (F) in or out until the front edge of the guides (D) are just behind the “gullets” of the blade teeth. Then tighten screw (E). 4. The upper blade support/thrust bearing (G) Fig. 22, prevents the saw blade from being pushed back too far when cutting. The support bearing (G) should be adjusted approximately 1/32" behind the blade, so the back of the blade overlaps the outside diameter of the ball bearing by approximately 1/8". To adjust, proceed as follows: DISCONNECT MACHINE FROM POWER SOURCE. 5. Loosen screw (H) Fig. 22, and slide support bearing (G) in or out until it is approximately 1/32" behind the saw blade. 6. The upper blade support bearing (G) Fig. 22, is set on an eccentric shaft. To change position of bearing (G), use a straight screwdriver, rotate shaft (J) Fig. 23, until the blade properly overlaps the support bearing. Then tighten screw (H). Fig. 22 G F H E C CD B J Fig. 23 13 ADJUSTING LOWER BLADE GUIDES AND BLADE SUPPORT BEARING The lower blade guides and blade support bearing should be adjusted at the same time as the upper guides and support bearings as follows: DISCONNECT MACHINE FROM POWER SOURCE. 1. Loosen two screws (A) Fig. 24, and move guides (B) as close as possible to the sides of the blade, being careful not to pinch the blade. Then tighten the two screws (A). 2. The front edge of guide blocks (B) Fig. 24, should be adjusted so they are just behind the “gullets” of the blade teeth by loosening screw (C), and moving assembly (D) in or out as necessary. Then tighten screw (C). 3. The lower blade support bearing (E) Fig. 24, should be adjusted to support the rear of the blade during the cutting operation and also prevent the blade from being pushed too far to the rear which could damage the blade. The support bearing (E) Fig. 24, should be set about 1/32" behind the blade by loosening screw (F) Fig. 24, and moving shaft (G) in or out. Then tighten screw (F). 4. The lower blade support bearing (E) Fig. 24, should also be adjusted so the back of the blade overlaps the outside diameter of the ball bearing by approximately 1/8". The blade support bearing (E) is set on an eccentric shaft.To change pos...
