MACHINE FEATURES (Continued....
INSTALLATION LIFTING All the “left”, “right”, “front” and “rear” designations in this manual are as viewed by the operator facing the machine's electrical controls. 1. LOCATION 1. 2. A tapped hole is located on top of the machine's saw head. Screw a forged 3/4-10NC eye-bolt into this hole for lifting purposes. Net weight of the machine is approximately 2250 pounds (1020.6 kg). DO NOT lift the machine by its sawing head. The floor area required by the standard machine is approximately 74.
MACHINE ALIGNMENT (Continued....) PREPARATION FOR USE 3. Place a good quality, 10 inch (254.0 mm) master square on the worktable against the post's back side. Measure clearance between the post and square near the bottom of the post. Clearance should be within 0.007-inch ±0.005-inch (0.18 mm ±0.13 mm) at the bottom of the post for standard machines. 1. 4. Add or remove shims under the base pads until the correct post to square clearance is obtained. Check the transmission oil level.
OPERATION SAFETY PRECAUTIONS Warning Label - READ and UNDERSTAND. USING THE JOB SELECTOR 1. Refer to the Job Selector chart located on the upper bandwheel door. It has information about the recommended band type and pitch, band speeds and cutting rates according to the type of material to be cut and its thickness. It also has a radius guide that shows the minimum radii cuts possible with various saw band widths. 2. To use, find the material to be cut in the first column.
ELECTRICAL CONTROLS BAND SPEED CONTROLS Electrical Box Enclosure 1. The transmission gear shift lever is located on the machine's right side under the worktable, the band speed knob is located on the pushbutton control box on the front of the machine. 2.
TABLE CONTROLS (Continued....) • Insert-Type Saw Guide Adjustment These instructions apply to both the upper and lower insert-type saw guide blocks. Table Feed. This valve with "REVERSE", "STOP", "FEED" and "FORWARD" settings controls table directional movement. "Feed" position is for sawing, "REVERSE" and "FORWARD" positions are for table set-up and/or rapid table movement, and "STOP" stops table movement in either direction. 1.
SAW BAND PREPARATION (Continued....) 2. A scale showing the recommended tension for various saw band widths is located to the right of the tension adjustment knob. Scale numbers represent the recommended tensions for common saw band gages and pitches. 3. Release saw band tension. Then: (a) Open all bandwheel doors; (b) Remove the post saw band guard; (c) Loosen the screw holding the worktable's sawing slot clamp bar and move it aside; (c) Loosen the saw guide inserts.
POST ADJUSTMENT 1. Post and upper saw guide elevation can be adjusted to accept workpieces with heights varying up to 12 inches (304.8 mm) (standard work height) by means of a handwheel located on the right side of the saw head. 2. Post and upper saw guide can be adjusted by turning the handwheel clockwise to "raise" the post and upper saw guide, counterclockwise to "lower" them. 3.
WHEEL BRUSH AND CHIP REMOVAL (Continued....) 2. 3. During operation, chips and other depris may accumulate around such machine areas as saw guides, worktable surfaces, bandwheels, slides, etc. Remove this debris as soon as possible. The DoALL Company recommends removing chip collections at least twice per each eight (8) hour shift, and more often with heavier use. See the "Maintainence" section of this manual for cleaning and adjustment procedures. TYPICAL SAWING PROCEDURES 8.
TYPICAL SAWING PROCEDURES (Continued....) 2. A hole is usually drilled in the stockpiece when a sharp corner is to be cut, as shown in the illustration. However, a corner may also be by-passed by cutting a curve, and leaving the remainder to be notched out later. Internal Contours 1. To prepare for internal contour sawing: (a) Drill a starting hole in the stock; (b) Run the saw band through the hole; (c) Weld the saw band.

MAINTENANCE REPLACING BANDWHEEL FLANGES ELECTRIC MOTORS 1. 1. Replace worn or damaged flange segments by removing the bandwheel from the machine. Then: (a) Remove the flnged segments; (b) Install new flange segments with their chamfered edge toward the tire. HEAD COMPONENTS 2. Loosen the worn tire with a screwdriver or other flat tool. Stretch or cut the tire if necessary to remove it. 3. Mount new tire with the steel backed notches in alignment with the retainers. 4.
WHEEL BRUSH 1. 2. Check the lower bandwheel brush occasionally for correct position. Adjust the brush so it just touches the bandwheel tire. Too much pressure of the brush will score the bandwheel tire. 2. Bleeding Air From The System 1. Replace the brush when necessary. BAND DRIVE BELT 1. The drive belt may stretch slightly after initial use. This stretch must be removed for proper operation. 2.
HYDRAULIC SYSTEM (Continued....) 4. See the "Adjustment Summary" for information on all hydraulic adjustment procedures. HYDRAULIC PUMP REPLACEMENT 1. DO NOT attempt to repair the hydraulic pump. Return it to the factory for repair or replacement. Be sure to specify the correct pump model and serial numbers when returning the unit. 2. Rotate the pump and motor by hand to insure free movement after installing a new unit.
TROUBLE SHOOTING Repair and adjustment procedures should be made by experienced maintenance personnel, or by a DoALL service representative. Reference to the machine's electrical and hydraulic schematics will be helpful. Make sure the disconnect switch is in the "ON" position. 2. Make sure the All Stop pushbutton has been reset (turn the button head clockwise). 3. Make sure the bandwheel doors are closed. 4. Check to see if the fuses and/or circuit breakers have tripped. 5.
TROUBLE SHOOTING (Continued....) 2. Check for a clogged coolant applicator nozzle. 4. 3. Check for a clogged or kinked coolant hose. 4. Check for a clogged or damaged coolant control valve. Check for a light feed pressure setting. Increase if necessary. 5. Coolant is not properly covering the saw band. 6. The cutting rate is too high. TRANSMISSION WILL NOT STAY IN GEAR 7. Check for faulty material such as heavy scale, inclusions, hard spots, etc. 1. 8. Check for saw band vibration. 9.
ACCESSORIES UNIVERSAL CALIBRATED WORK FIXTURE The following are accessories sometimes used during contour sawing operations. A DoALL Sales representative will be happy to advise you about the current availability of any accessory. Set-Up for Straight Cut-Off 1. Place the fixture on the worktable at the required distance from the saw band. Then: (a) Loosely install T-nuts and screws; (b) If necessary, align the scale's zero (0) mark with the saw band, then "zero" the pointer. 2.
WORKHOLDING JAWS UNIVERSAL CALIBRATED WORK FIXTURE (Continued....) 2. 3. 1. Mount the collar on the right T-nut and fasten it to the worktable (against the back-up bar) with the socket head screw. Then: (a) Run the worktable forward until the back-up bar barely touches the saw band; (b) Set the workstop for the required stock length dimension. The back-up bar scale is not used for angle cuts. This option is used for off-hand and contour sawing.
DUST SPOUT Insert-Type Saw Guides 1. • This option is located just below the worktable on the right side of the machine frame near the lower saw guide and attached to a collection system for disposal of chips and other waste materials. High speed, heavy-duty saw guide blocks are for band speeds up to 6000 fpm (1830 m/min). BANDWHEELS 1. Your machine may be equipped with flanged metal face or center crowned rubber tired bandwheels instead of the standard rubber faced flanged bandwheels.
OPTIONAL SAW GUIDE BLOCKS (Continued....) • In "MANUAL", the foot switch is disconnected and standard operation is active. • In the "CONTOUR" setting, the foot switch operates the table in "FORWARD" or "REVERSE" settings of the table feed control valve at controlled feed rates set by the operator. • The "PRODUCTION" setting operates the table at controlled forward feed rate but with a fast table return stroke. Type II Roller Saw Guides. 2.
LASER LINE GENERATOR OPTION To avoid eye damage, DO NOT stare into the laser beam. 1. A laser devise is used to emit a line on the material to be cut. This line shows the approximate spot where the cut will take place. 2. The devise is controlled by a selector switch with "ON" and "OFF" settings and is located on or near the control panel. Turn the laser "OFF" when not in use. 3. The laser is adjustable to position the laser beam where desirable. 4.
