Chip Collection

1. 

Most metal chips removed from the saw band 

and from the stock drop onto the coolant pan.  

Periodically remove the chips.

Machine Cleaning

1. 

During the sawing process, the operator should 

check often for chip accumulations around such 

machine areas as:  saw guides, vise bed, vise 

jaws, head feed cylinder, bandwheels, etc.  These 

accumulations can affect machine performance 

and accuracy and should be removed from these 

areas as often as possible.  

Removing chips 

at least twice per each eight (8) hour shift is 

recommended; more often with heavier use.

 

Be sure the band drive motor and the saw band 

are STOPPED completely before clean- 

ing the machine.

REPLACING VISE BED WEAR PLATE

1. 

The machine's vise bed is covered by three (3) steel 

plates which must be replaced before their mounting 

screw heads become worn and damaged (making 

removal difficult).  It can be removed when the vise 

jaw is at the 

maximum open

 position.

2. 

Follow these vise bed replacement directions:  

(a)

 

Move the vise jaw to its maximum open position; 

(b)

 

Remove all wear plate mounting screws; 

(c)

 Install 

new wear plate and mounting screws.

• 

The operator will have to remove the larger wear 

plate first to remove the wear plate under the vise 

jaws.

BANDWHEELS

1. 

Remove the bandwheels every six (6) months to 

clean them and the surrounding machine areas.

Bandwheel Flange and Tread.

BAND TENSION ADJUSTMENT

1. 

Tension adjustment of the saw band will be 

necessary from time to time.  Adjustment is made 

by turning the upper handwheel extending from the 

machine's left side.

2. 

Correct band tension will stress a high-speed steel 

saw band to 30,000 psi (2115 kg/cm²).  This is 

comparable to a Tensigage reading of 4.0 units or 

30,000 psi (2115 kg/cm²) measured by a DoALL 

Tensigage.  Refer also to the band tensioning portion 

in the "

OPERATION"

 section of this manual.

FLOOD COOLANT

1. 

Check the coolant often for signs of contamination 

or breakdown.  Drain the entire system and clean 

it thoroughly when coolant becomes unsuitable for 

further use.

2. 

Empty the reservoir periodically and clean the 

coolant screens.

3. 

Flush the entire coolant system with DoALL's "Kleen 

Flush" when changing to a different coolant type.

CHIP REMOVAL

Band Brush

1. 

The band chip brush should be positioned so that its 

bristles remove all metal chips from the blade tooth 

gullets, but do not touch the bottom of the gullets.  

Replace the brush if its bristles become too worn 

for proper blade cleaning.

2. 

To replace the brush or adjust it to a new position:  

(a)

 

Loosen the carriage bolts that hold the band 

brush to the mounting bracket; 

(b)

 Remove the 

nut to replace the brush; 

(c)

 Place new brushes 

and reinstall the nut; 

(d) 

Adjust the band brush into 

position as described above.
