1)  Give machine an overall inspection. Verify that 

all  guards,  covers,  etc.  are  in  place  and  in 
working order, the blade is tensioned properly, 
and  tooth  direction  matches  arrow  on  bow. 
Check that blade guides and wire brush are set 
correctly. 

2)  Raise bow until it will clear workpiece by a few 

inches,  and  secure  in  position  by  closing 
cylinder valve. 

 

Always  secure  bow  in 

raised  position  before  loading  material. 
Never  start  a  cut  with  blade  contacting 
workpiece.

 

3)  Position  workpiece  in  vise  and  tighten  vise. 

Workpiece should be fitted directly between the 
jaws without adding other objects. When work 
piece  is  profiled  section,  flat  piece  or  special 
shape,  refer  to  examples  in  Figure  9-1  for 
proper clamping positions. The top row shows 
acceptable clamping positions, the bottom row 
show 

un

acceptable positions. 

If the thickness of profile section is very thin, a 
piece  which  duplicates  the  profile  should  be 
fitted  inside  the  workpiece  itself,  to  prevent 
workpiece being crushed between the jaws. 

 

Do  not  load/unload  material 

from vise while machine is running. Never hold 
workpiece  by  hand  when  cutting;  workpiece 
must be firmly secured in vise. Do not reach into 
cutting area during cutting operations.

4)  Adjust  left  blade  guide  to  minimize  exposed 

blade area. 

5)  Set suitable feed rate on cylinder dial. 
6)  Open  coolant  valve,  and  open  valve  on 

hydraulic  cylinder  to  allow  bow  to  descend  in 
gradual and controlled manner. 

7)  Switch trip tab must turn off saw at completion 

of cut.  

9.3

  Evaluating Cutting Efficiency 

Is  the  blade  cutting  efficiently?  The  best  way  to 
determine this is to observe the chips formed by the 
cutting blade. 
If  chip  formation  is  powdery,  then  the  feed  rate  is 
much too light, or the blade is dull. 

If  chips  formed  are  curled,  but  colored  —  that  is, 
either  blue  or  straw-colored  from  heat  generated 
during the cut — then the feed rate is too high. 
If  chips  are  slightly  curled  and  are  not  colored  by 
heat – the blade is sufficiently sharp and is cutting 
at its most efficient rate.

  User-Maintenance 

 Always  disconnect  power  to 

machine  before  performing  maintenance.   
Failure to do this may result in serious personal 
injury. 

Keep all surfaces clean and free of rust, slag, chips, 
and coolant build-up. 
Clear  metal  particles  with  a  small  paint  brush  or 
parts cleaning brush. Do not use compressed air, as 
it may force chips into the guide bearings and other 
critical areas of the saw.  
Clean drain filter assembly. 
Make frequent inspections of motor fan and blow out 
(with  low  pressure  air  hose)  or  vacuum  any 
accumulation of foreign material to maintain normal 
motor ventilation.  
Wipe saw down with a clean, dry cloth, and oil all 
unpainted surfaces with light machine oil. 
Keep blade guides clean and free of metal particles. 
Check guide bearings frequently to make sure that 
they are properly adjusted and turning freely. 
Periodically inspect belt for wear or fraying. Replace 
if needed. 
To prevent corrosion of machined surfaces when a 
soluble  oil  is  used  as  coolant,  pay  particular 
attention  to  wiping  dry  the  surfaces  where  fluid 
accumulates and does not evaporate quickly, such 
as between machine bed and vise. 
Place a thin coat of oil on bed surface on which vise 
jaw slides. 
If the power cord is worn, cut, or damaged in any 
way, have it replaced immediately.

 

10.1

  Lubrication 

All  ball  bearings  are  permanently  lubricated  and 
sealed. They require no further lubrication. 
Lubricate  the  vise  lead  screw  as  needed  with  #2 
tube grease. 
Drain  and  refill  gear  box  oil  after  first  90  days  of 
operation.  Thereafter,  change  every  six  months. 
Use 90W oil. 
To change gear box oil: 
1)  Disconnect machine from power source. 
2)  Place bow in horizontal position. 
3)  Remove four screws from gear box and remove 

cover plate and gasket. If more space is needed 
to  access  gearbox,  remove  belt  and  adjust 
motor away.
