Hydraulic System
Symptom Possible Cause Possible Solution
Hydraulics are not
functioning. 1. Hydraulic fluid level is low.
2. Insufficient system pressure.
3. Hydraulic system is leaking.
4. Flow blocked or impeded.
5. Control panel or electrical cabinet wiring at
fault.
6. Hydraulic pump at fault.
1. Check/fill hydraulic fluid level ( Page 54).
2. Adjust system pressure ( Page 53).
3. Inspect/test for leaks/repair.
4. Make sure hydraulic line(s) are not pinched or
damaged.
5. Check that hydraulic pump motor is running and
that solenoids are activating (indicated by red LED
in solenoid plug). Repair/replace if at fault.
6. Test/repair/replace.
Vise does not open/
close. 1. Vise valve solenoids at fault.
2. Vise valve solenoids connections are bad.
3. Vise hydraulic system is leaking.
4. Control panel or electrical cabinet wiring at
fault.
5. Hydraulic pump at fault.
1. Test/repair/replace.
2. Check solenoid plugs.
3. Test for leaks/repair.
4. Check that hydraulic pump motor is running and
that solenoids are activating (indicated by red LED
in solenoid plug). Repair/replace if at fault.
5. Test/repair/replace.
Headstock does not
raise/lower. 1. Headstock valve solenoids at fault.
2. Headstock valve solenoids connections are
bad.
3. Headstock hydraulic system is leaking.
4. Control panel or electrical cabinet wiring at
fault.
5. Hydraulic pump at fault.
1. Test/repair/replace.
2. Check solenoid plugs.
3. Test for leaks/repair.
4. Check that hydraulic pump motor is running and
that solenoids are activating (indicated by red LED
in solenoid plug). Repair/replace if at fault.
5. Test/repair/replace.
Symptom Possible Cause Possible Solution
Blade wears on
one side or shows
overheating. 1. Blade guides worn or mis-adjusted.
2. Blade not supported.
3. Dull/incorrect blade.
4. Incorrect coolant mixture for workpiece/cut.
5. Blade is bell-mouthed.
1. Re-adjust guides and bearings (
Page 66)/replace.
2. Move left blade guide arm closer to workpiece
( Page 37).
3. Replace blade ( Page 34).
4. Use correct coolant mixture.
5. Replace blade (
Page 34).
Blade tracks
incorrectly, or
comes off wheels. 1. Feed rate too fast/wrong TPI.
2. Blade tension/tracking requires adjustment.
3. Blade guides need adjustment.
4. Blade bell-mouthed.
1. Reduce feed rate ( Page 31)/decrease blade TPI
( Page 28).
2. Adjust blade tracking ( Page 68), tension (Page 36).
3. Adjust blade guides (
Page 66).
4. Replace blade (
Page 34).
Cuts are crooked/
excessively rough. 1. Feed rate too fast; blade speed incorrect.
2. Blade is too course or dull.
3. Blade not supported.
4. Carbide blade guides/roller bearings out of
adjustment.
5. Blade tension/tracking requires adjustment.
6. Feed pressure is too great.
1. Reduce feed rate ( Page 31); adjust blade speed
(
Page 31).
2. Replace blade (
Page 34).
3. Move left blade guide arm closer to workpiece
( Page 37).
4. Adjust carbide blade guides/roller bearings
(
Page 66).
5. Adjust blade tracking (
Page 68), tension (Page 36).
6. Increase headstock spring tension ( Page 73).
Blade keeps moving
or headstock not
raising after cut. 1. Downfeed stop limit switch not engaged/at
fault.
1. Adjust downfeed stop bolt ( Page 72); test/replace
limit switch if at fault.
