NEVER adjust the band brush while the 

saw band is running or allow metal chips to 

accumulate on the brush.

Chip Removal

1. 

Metal fragments removed from the band brush and 

from the stockpiece drop onto the coolant pan.  Chip 

collections should be removed from the coolant pan 

when necessary.

2. 

In addition, the operator should check often for 

chip accumulations around such machine areas 

as:  saw guides, vise bed, vise jaws, head feed 

cylinder, etc.  These accumulations may affect 

machine performance if not removed.  Remove chip 

accumulations at least twice per eight (8) hour shift 

and more often with heavier use.

 

Be sure the band drive motor and the saw band 

are STOPPED completely before cleaning the 

machine.

TYPICAL OPERATION PROCEDURES

Preparation

1. 

These operations assume that the machine is 

prepared as follows:  

(a)

 The band drive motor is 

"OFF"; 

(b)

 The saw band is properly installed and 

tensioned; 

(c)

 Both bandwheel doors are closed; 

(d)

 All guards are in place and/or secured; 

(e)

 The 

coolant reservoir or the optional Mist Lubricator 

reservoir is full and all lubrication points are properly 

serviced and if necessary, press the "COOLANT" 

key with the desired delivery mode; 

(f)

 The band 

brush is properly positioned; 

(g)

 The work height is 

adjusted for material size.

Manual Operation

1. 

On the 

VIEW

 screen, make sure the "MANUAL 

MODE" key is activated.

2. 

Go to the 

VIEW 

Screen

 

and then press the 

"HYDRAULIC START" key.

3. 

If desirable, press the "VISE CLAMPED DELAY" 

key(s) to change the time delay values, enter the 

value for each using the pop-up keypad and then 

press OK.

4. 

Press a "COOLANT" key selection that is correct 

for the application.

5. 

Go to the 

VIEW 

Screen

 

and then press the "SAW 

HEAD UP" key.  Raise the saw head all the way to 

the head clear position.  The vises now enabled be 

opened to its full open position.

6. 

Press and hold the "INDEX VISE OPEN" key to 

open the vise wide enough for stock to be placed 

between the jaws.  Release the keys to stop vise 

movement.  Repeat the action for the front vise.

7. 

Load the stock to be cut onto the indexer roller bed 

near the fixed vise jaws and manually position for 

a crop cut if desired.

• 

To move the stock into position for clamping using the 

indexer:  

(a)

 Press the "INDEXER REVERSE" key to 

move the index vise to the rear limit of its travel; 

(b)

 

Press the "INDEX VISE CLAMP" key to clamp the 

stock; 

(c)

 Press the "INDEXER FORWARD" key to 

position the stock extending beyond the saw band 

and enough stock for the front vise to clamp.

8. 

On the hydraulic control panel, turn the 

Feed Rate

 

control fully 

clockwise

 to stop the feed.

 

DO NOT over tighten.  To prevent damage to 

the Feed Rate valve, turn only enough to seat 

the needle of the valve.

9. 

Press the "FRONT VISE CLAMP" key to clamp the 

stock.  Then:  

(a)

 Press the "SAW HEAD DOWN" 

key and release the "SAW HEAD DOWN" key when 

the saw band is just above the stock to be cut; 

(b)

 

Press the "BAND SPEED" key and enter the desired 

speed and press 

OK

.

10. 

Press the "BAND/CYCLE START" key.  As the saw 

band drive comes up to speed and coolant begins to 

flow, the saw head will descend when the operator 

adjusts the 

Feed Rate

 control 

counterclockwise

 

to begin saw head feed.

11. 

The operator may adjust band speed, coolant flow, 

feed rate, and/or feed force at any time during the 

sawing process.

 

DO NOT remove the cut-off piece until the saw 

band has stopped completely.

12. 

After the cut has been completed, the saw band 

will shut off with the saw head in the down position.  

Remove the cut-off piece.

14. 

If more cuts are to be made:  

(a)

 Raise the saw 

head until the desired saw head height is reached; 

(b)

 Unclamp the vise jaws; 

(c)

 Position stock for 

another cut; 

(d)

  Clamp  the  vises; 

(e)

  Press  the 

"BAND/CYCLE START" key.
