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.
