Themachinemust beboltedtotheoorfor
table loads over 100 pounds (45.4 kg).
Worktable.
2. The worktable can be tilted manually up to 10º left and 45º right -- primarily for sawing compound angles. The amount of worktable tilt is indicated by a pointer and a trunnion-mounted calibrated scale.
3. To tilt the worktable: (a) Use the wrench provided to reach through the machine frame and under the worktable to loosen the tilt locknut; (b) Tilt the worktable manually until the pointer reaches desired angle shown on the scale; (c) Tighten the tilt locknut.
4. The worktable is drilled and tapped on three (3) sides to attach accessory equipment. Its removable center plate can be replaced with optional plates for
band ling and band polishing and other various
options.
WHEEL BRUSH AND CHIP REMOVAL
2. 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.
TYPICAL SAWING PROCEDURES
Set-Up
1. These procedures assume that the following machine conditions exist: (a) The machine has been properly installed and aligned; (b) The band drive motor is off; (c) The proper saw band has been installed, is correctly tracked and tensioned; (d) All lubrication procedures have been carried out.
Procedure
1. Raise the post high enough so that the upper saw guide can not be damaged while stock is being loaded onto the worktable.
2. Tilt the worktable to the desired angle and lock it in place.
3. Load stock to be cut onto the worktable. Clamp the
stock if required.
4. Lower the post until the upper saw guide is just
above the stock, but NOT touching.
5. Determine the band speed range and desired band speed for the procedure to be undertaken. Then: (a) Use the transmission gear shift lever to choose between "high" and "low" band speed ranges; (b)
Push the Band Start button; (c) Turn the Band Speed knob to the band speed desired.
6. Before starting the cut, make sure to adjust the mist
coolant spray (if supplied) onto the saw band and cutting area.
1. A brush, lo c ated on the lower ba n dwheel approximately in the ten (10) o'clock position, cleans metal chips from the bandwheel during machine operation. Removed chips drop into a removable pan in the machine base. This pan should be emptied periodically.
DO NOT open the bandwheel doors until saw
band has completely stopped.
7. Carefully move the stock toward the saw band and begin the cut. Adjust the band speed as necessary
during the cutting procedure.
8. After the cut has been nished: (a) Turn the Band Speed knob to its lowest speed; (b) Push the Band Stop button; (c) Remove the piece just cut from the
worktable; (d) Reposition the stock to begin another cut; (e) Push the Band Start button and then set the band speed.
11
TYPICAL SAWING PROCEDURES
Continued....)
9. The following are important sawing precautions which should be observes:
DO NOT feed work so rapidly that saw band
twisting or bowing occurs.
Reduce the feed force when cutting into an
opening to prevent saw band damage.
For future reference, keep a record of band
speeds, coolant application, etc. and other settings for successful jobs.
Contour Sawing
1. Procedures for stock set-up and band speed adjustment are the same as noted for production
sawing except that contour sawing of large, heavy stock will require the use of optional air-operated power feed or air-powered worktable and a heavy gage saw band.
Internal Contour Sawing.
2. The diameter of the drilled starting hole is determined by the size of the saw band being used. Use the widest possible saw band for cutting the curve.
Starting Hole for Sharp Contour Cutting.
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. Insulate
the saw band from contact with the stock or the worktable will insure a better weld.
3. Attempting to cut too small a radius with too wide a saw band will cause binding, and the lower bandwheel may become grooved. The chart on the Job Selector shows minimum radii cuts possible with various saw band widths.
4. Radii chart recommendations are based on sawing relatively thin stock. Consider these variations: (a) Use a heavy gage saw band for heavy stock sawing; (b) Use a narrower than recommended saw band when sawing stock more than one (1) inch (25.4 mm) thick.

ACCESSORIES
The following are accessories sometimes
used during sawing operations. A DoALL sales representative will be happy to advise you about the current availability of any ac­cessory.
DISC CUTTER
1. This attachment can be used to cut internal or ex­ternal circles from 2-1/2 to 30 inches (63.5 to 762.0 mm) in diameter. To set up the disc cutter:
Place at washers under the mounting screws.
Then: (a) Bolt the mounting bracket to the post; (b) Lower the post until the upper saw guide is ap-
proximately 3/8 inch (10 mm) above the worktable;
(c) Loosen the ne adjustment and arm clamp bolts; (d) Move the center pin to the approximate distance
of the radius to be cut; (e) Tighten the ne adjust­ment clamp bolt.
Miter No. 2 Cut-Off Option.
2. When not in use, this unit can be swung upward and around on the slide rod so that it hangs down below the worktable surface.
RIP FENCE
1. Square this xture during installation so that it is in
line with the worktable sawing slot. When alignment
is correct, secure the adjusting screws in place with
the set screws under the the guide bar on the rip fence casting.
Disc Cutter.
Position the center pin so that it is perpendicular to
the saw band's cutting edge. To do so: (a) Place a square against the tip of a sawband tooth; (b) Loosen the vertical adjustment clamp bolt; (c) Line up the center pin with the square's blade edge; (d)
Clamp the vertical adjustment clamp bolt.
Make nal radius adjustments with the ne adjust-
ment wheel. Then: (a) tighten the arm and radius arm clamp bolts while making sure the center pin is square to the table; (b) Adjust the disc cutter for stock thickness by raising or lowering the post.
MITER NO. 2 CUT-OFF (Side Mount)
1. To set up: (a) Place a combination square in the worktable sawing slot to check the alignment; (b) Set the bar for sawing at the desired angle. It is im­portant that the mitering bar contact the worktable's surface evenly during use.
2. Before attempting a long cut, check to see that the saw band is not worn on one side. This will cause stock to wander relative to the rip fence guide bar.

Heavy Work Slides.
WORKHOLDING JAWS
1. This option is used for off-hand and contour saw­ing. By looping a power feed chain around the
workholding jaws, the operator can use the cable
pulley system to guide stock along the contour layout lines.
Be sure to use the correct saw band width
when cutting a radius.
Adjust the pulley and cable system for stock width.
This is done by: (a) Loosening the two (2) knobs located under the rear mounting bracket; (b) Re­moving any slack in the workholding chain.
Chain and Pulley System.
Set the desired feed force with the regulating valve knob. Turn the knob clockwise to increase feed force, counterclockwise to decrease it. Refer to the gauge for pressure readings.

AIR-OPERATED POWER FEED
This option requires shop air: 20 psi (1.4 kg/
cm²) minimum; 100 psi (7.0 kg/cm²) maximum. It has been tested at 70 psi (4.9 kg/cm²) pres­sure during factory inspection.
1. Air power feed provides steady feeding pressure and allows the operator to use both hands to guide the stockpiece.
2. This system has: (a) A pressure-regulating valve and gauge located slightly below the left worktable surface; (b) A pulley and cable system attached by
an adjustable bracket to the rear worktable edge
and to an air cylinder mounted to the machine base.
Pressure Valve and Gauge.
Place stock between the workholding jaws and
remove any slack in the cable. Next: (a) Start the machine; (b) Begin the cut by pushing down slightly on the foot pedal.
Feed force can be increased while sawing by ap­plying additional pressure on the foot pedal. When
the sawing is nished, remove your foot from the
pedal to relax feed force.
A special oil-mist lubricator is included with
this option.
21
CHIP BLOWER
1. The operator can remove chips from the sawing area by using the chip blower. Shop air is used to deliver air to the cutting area.
2 . A protective lens cover should be placed around
the magnier to prevent scratches when not being
used.
POST ELEVATING HANDWHEEL
2. Adjust the exible hose and nozzle to direct chips
away from the sawing area.
3. The air supply connection is located on the left side of the machine on the drive compartment wall. Incoming air supply should be between 80 and 90 psi (5.6 and 6.3 kg/cm²).
DO NOT exceed 90 psi (6.3 kg/cm²).
MIST COOLANT
1. Using shop air, this option has a valve with sight glass and a one (1) quart (0.95 liter) supply bottle mounted on the rear side of the head.
2. Air and coolant are mixed in a manifold to form
a ne mist. Adjust the exible tube to direct mist
stream onto saw band and workpiece to lubricate and cool the cutting area. Regulate mist with ad-
justable valve at a rate of one drop per second as
seen through the sight glass.
3. The air supply connection is located on the left side of the machine on the drive compartment wall. Incoming air supply should be between 80 and 90 psi (5.5 and 6.2 bar or 5.6 and 6.3 kg/cm²).
DO NOT exceed 90 psi (6.2 bar or 6.3 kg/
cm²).
4. Your DoALL sales representative can provide complete information on various coolants and their applications
.
BAND MIST LUBRICATOR
1. See the instructions sent with the unit for information
on operation and adjustments.
WORKLIGHT
1. The worklight illuminates the cutting area and areas nearby and is controlled by an "on/off" switch on the lamp, or by selector switch on the electrical control box.
