TROUBLE SHOOTING (Continued....)
12. Check for coolant not being supplied evenly to both
sides of the saw band.
SURFACE FINISH OF CUT-OFF PIECE IS TOO
ROUGH
1. Check for vibration while sawing.
2. Check for a damaged saw band.
3. Use a ner pitch saw band.
4. Increase band speed being used and/or decrease
the feed rate.
5. Check the saw band back-up guides for wear.
Replace them if necessary.
6. Check for incorrect saw band tension.
CUTTING RATE IS TOO SLOW
1. Use a courser pitch saw band.
2. Increase band speed and/or feed force.
STOCK FEEDS ERRATICALLY
1. Check for low hydraulic system oil level.
INDEX VISE WON'TMOVE FORWARD
1. Check to see if Solenoid 6 is operating.
VISES WON'T TRANSFER AFTER AN INDEX
1. Check for faulty operation of the index forward
proximity switch (4 PRS or 4 LS) on the index vise
base.
2. Check for faulty operation of Solenoid 9 and 10.
INDEX WON'T RETURN
1. Check to see if Solenoid 5 is operating.
2. Check for incorrect adjustment of the index forward
proximity switch (4 PRS or 4 LS).
VISES WON’T TRANSFER and SAW HEAD
STAYS DOWN
1. Check for faulty operation of the head down proximity
switch (2 PRS or 2 LS).
2. Check to see if Solenoid 2 is energized.
3. Check to see if Solenoids 8 and 11 are
operating.
SAW HEAD WON’T LOWER
1. The feed rate setting is too low.
2. Check the head clear proximity switch (3 or 2 PRS)
for faulty operation.
3. Check Solenoids 1 and 12 for incorrect
operation.
4. Check for saw head obstruction.
SAW HEAD WILL NOT RAISE, OR RAISES
SLOWLY
1. Check for faulty Solenoid 2 operation.
2. Check for low hydraulic system pressure caused
by blockage, clogged oil lter cartridge, or pinched
hose.
SAW HEAD LOWERS ERRATICALLY
1. Bleed air from the head lift cylinder. It may be
necessary to raise and lower the saw head several
times to thoroughly bleed the head lift cylinder.
SAW HEAD WON'T STOP AT THE CORRECT
STOCK HEIGHT
1. Check the stock height sensing arm. Is it positioned
correctly relative to the saw band?
2. Check to see if the sensing arm is properly actuating
the head clear proximity switch (3 or 2 PRS).
3. Check for faulty Solenoid 2 operation.
SAW HEAD DOESN'T LOWER FOR REPEAT
CUTS
1. Check for faulty operation of Solenoids 1 and 12.
2. Check adjustment of the head clear proximity switch
(3 or 2 PRS).
3. Check the index forward proximity switch (4 PRS
or 4 LS).
