DAMAGE CLAIM PROCEDURES

VISIBLE DAMAGE AT THE TIME OF DELIVERY:

1. Note damage on carrier’s delivery receipt. Accept the shipment. It can be returned later if repairs

are not possible in the eld.

2. Request a “damage inspection” from the delivery carrier:

a. The carrier will send his own people or contract an independent agency to make the

inspection.

b. The inspector will request a signature on the report and leave a copy.

c. The carrier “damage inspection” report is not nal. If additional damage is found when

repairs are started, contact the carrier for another inspection; or at least give them the details of the damage.

3. Do not move the equipment from the receiving area and keep all shipping materials until carrier “damage inspection” report is complete.

4. If possible, take photographs of the damage and keep them for your les. Photos could possibly

prove a claim at a later time.

5. Keep a record of all expenses and be sure they are documented.

6. Repair damage in the eld whenever possible. Carriers encourage this to keep expenses down.

7. You have nine (9) months to le a claim.

CONCEALED DAMAGE:

1. You have fourteen (14) days to report damage not noted at time of delivery.

a. Report damage as soon as possible. This makes it easier to prove that it did not happen

at cosignee’s plant.

b. Inspect machine(s) carefully before moving from the receiving area. Again, if machine is

not moved, it is easier to prove your case.

2. Request a “damage inspection” from the delivery carrier:

a. The carrier will send his own people or contract an independent agency to make the

inspection.

b. The inspector will request a signature on the report and leave a copy.

c. The carrier “damage inspection” report is not nal. If additional damage is found when

repairs are started, contact the carrier for another inspection; or at least give them the details of the damage.

3. Do not move the equipment from the receiving area and keep all shipping materials until carrier “damage inspection” report is complete.

4. If possible, take photographs of the damage and keep them for your les. Photos could possibly

prove a claim at a later time.

5. Keep a record of all expenses and be sure they are documented.

6. Repair damage in the eld whenever possible. Carriers encourage this to keep expenses down.

7. You have nine (9) months to le a claim.

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.

Page 15

WORKTABLE AND TILT ADJUSTMENT

(Continued....)

3. Load stock to be cut onto the worktable. Clamp the

stock if necessary.

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

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.

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.

4. Lower the post until the upper saw guide is just

above the stock, but NOT touching.

5. Determine the desired band speed for the procedure to be undertaken. Then: (a) Push the Band Start button; (b) Turn the Band Speed knob to the band speed desired.

6. Carefully move the stock toward the saw band and begin the cut. Adjust the band speed as necessary

during the cutting procedure.

7. After the cut has been nished: (a) Turn the Band Speed knob to its lowest speed; (b) Push the 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.

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.

2. The followin g are important contour sawing precautions which should be observed:

Reduce the feed force when cutting into an

opening to prevent saw band damage.

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.

DO NOT feed work so rapidly that saw band

twisting or bowing occurs.

For future reference, keep a record of band

speed, feed pressure and coolant application settings for successful jobs.

3. 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.

Page 16

TYPICAL SAWING PROCEDURES

Continued....)

Starting Hole for Sharp Contour Cutting.

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.

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.

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.

Internal Contour Sawing.

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.

2. Choice of blade pitch is incorrect.

3. Stock is not being clamped rmly to the worktable and/or by optional vise jaws.

4. Check for worn or improperly adjusted saw guide

inserts.

5. Check for a worn saw guide back-up bearing.

EXCESSIVE INSERT AND BLADE WEAR

1. Inserts or roller saw guide are adjusted too tightly

on the saw band.

2. High band speed is causing friction (using roller saw guides may be adviseable). Increase coolant volume to better lubricate the saw band.

3. The back-up bearing may need replacement.

4. Check for incorrect saw band tension setting.

5. Wheel brush is worn or not properly adjusted

causing chips to stay on the bandwheel.

PREMATURE BLADE TEETH DULLING

1. The saw band is not being "broken" in on the rst few

cuts. Reduce the feeding pressure when making these cuts.

2. Band speed is too high (this causes abrasion).

6. Check for a loose post. Adjust the cover plate if

necessary.

7. Check for a poor weld in the saw band.

8. Check for an incorrect saw band tension setting.

3. Saw band pitch is too coarse.
