CHIP REMOVAL
1. Metal chips should be removed from the work area as
soon as possible. They can be washed or scraped
into the right front pan opening, or scooped out with
the supplied shovel-rake.
DO NOT shovel or rake chps whle the saw
band s runnng.
Band Brush
1. A band brush powered by the lower bandwheel and
removes metal chips from the saw band. During
machine operation, the brush bristles should be
positioned so that the tips clean chips from the blade
teeth gullets, but do not contact the bottom of the
gullets. DO NOT allow metal chps to accumulate
on the brush.
Chip Removal Points.
Flushng Hose
1. Metal chips and other debris may accumulate over
time around such machine areas as: saw guides,
drive and idler bandwheels, vises, slides, feed and
discharge areas, etc.
2. The operator should check often for metal chip
collections which can adversely affect machine
performance. They should be removed with the
Flushng Hose as soon as possible.
The DoALL Company recommends usng the
Flushng Hose to remove chps at least twce
per each eght (8) hour shft, and more often
wth heaver use.
COOLANT SYSTEM
Coolant Selecton
1. The main cause of tooth failure during band
machining is excessive heat build-up. Using the
proper cutting fluid reduces the heat generated
during operation. It also helps the machine take
full advantage of its high-speed steel saw bands.
Lterature descrbng these and other coolant
types s avalable from a DoALL sales
representatve.
Coolant Applcaton
1. Coolant is applied as follows during sawing:
• To the saw band and cutting area through the saw
guide inserts. Flow is regulated by a valve on the
control panel.
• To a flushing nozzle for washing parts or cleaning
areas of the machine.
2. Coolant flow is started by: (a) Pushing the Hydraulc
Start button; (b) Turning the Coolant selector to
"ON" or "BAND ON"; (c) Turning the coolant valve
on the control panel clockwse until fluid completely
shrouds the saw band.
DO NOT start cutting until coolant is flowing
adequately. Dry cuttng wll greatly reduce
blade lfe.
3. Check the coolant level if flow is stopped or reduced.
Drip pan capacity is 20 gallons (75.7 liters). Chip
conveyor option has a capacity of 50 gallons (189.2
liters).
HYDRAULIC SYSTEM
1. The hydraulic and band drive systems operate
independently. This allows the operator to perform
the following tasks while the band drive motor is not
runnng : (a) Change saw bands; (b) Traverse the
sawing head; (c) Clamp or unclamp the vises; (d)
Position stock manually.
2. The machine's hydraulic reservoir has a 20 gallon
(75.7 liter) capacity. Refer to the Lubrication section
of this manual for recommended oils.
