Model G0887 (Mfd. Since 01/19)
Operation
Symptom Possible Cause Possible Solution
Vibration when
operating or cutting. 1. Loose or damaged blade.
2. Worn wheel bearing.
3. Bent or dull blade.
4. Machine component(s) loose.
5. Wheels worn or incorrectly installed.
6. Wheel appears bent.
7. Gearbox at fault. 1. Tension blade (
Page 36)/replace blade (Page 34).
2. Check/replace wheel bearing.
3. Replace blade (
Page 34).
4. Inspect/re-tighten component(s).
5. Replace wheels; adjust blade tracking (
Page 68).
6. Check/replace wheel/wheel bearing.
7. Rebuild gearbox; replace bad gear(s)/bearing(s).
Ticking sound when
saw is running. 1. Blade weld contacting blade guides.
2. Blade weld may be failing.
3. Blade teeth missing or broken.
4. Blade speed sensor adjusted too close to
pulley.
1. Grind weld down flush with blade.
2. Cut and reweld blade, or replace blade (
Page 34).
3. Inspect/replace blade (
Page 34).
4. Adjust blade speed sensor 5mm from
pulley ( Page 74).
Machine or blade
bogs down in cut. 1. Feed rate too fast; blade speed too low.
2. Belt slipping.
3. Blade loading up.
4. Blade dull.
5. Blade not supported; blade tracking
incorrectly.
6. Blade TPI incorrect.
7. Blade tension too low.
8. Material requires cutting fluid/lubrication.
1. Reduce feed rate (
Page 31); increase blade speed
(
Page 31).
2. Tension/replace belt ( Page 74).
3. Install blade with fewer TPI/different style of teeth
( Page 34).
4. Replace blade (
Page 34).
5. Move left blade guide arm closer to workpiece
(
Page 37); adjust blade tracking (Page 68).
6. Verify blade has at least 3 teeth contacting material
at all times ( Page 28).
7. Clean wheels; increase blade tension (
Page 36).
8. Use applicable coolant/lubricant.
Cuts not square. 1. Blade not square to table. 1. Adjust blade square to table ( Page 70).
Blade dulls
prematurely, or
metal sticks to
blade. 1. Blade improperly broken in.
2. Blade gullets loading up with chips.
3. Blade tension is too low.
4. Blade TPI too fine or course for material;
teeth load up and overheat.
5. Incorrect coolant mixture for workpiece/cut.
6. Inadequate feed pressure.
1. Replace blade ( Page 34); complete blade break-in
procedure ( Page 30).
2. Use blade with larger gullets ( Page 34).
3. Increase blade tension (
Page 36).
4. Use coarser-tooth or finer-tooth blade (
Page 34);
adjust feed rate ( Page 31); adjust blade speed
( Page 31); make sure blade brush works and is
adjusted correctly ( Page 65).
5. Use correct coolant mixture.
6. Decrease headstock spring tension (
Page 73).
Excessive blade
breakage. 1. Workpiece loose.
2. Blade contacting workpiece when started.
3. Blade too thick/blade gullets too large.
4. Workpiece too course for blade.
5. Blade tension/tracking requires adjustment.
6. Blade guide roller bearings require
adjustment.
7. Blade weld may be failing.
1. Secure workpiece with vise; increase vise clamping
pressure (
Page 42).
2. Raise headstock, start blade, then lower blade into
workpiece.
3. Use thinner blade/blade with smaller gullets
( Page 34).
4. Use coarser-tooth blade (
Page 34); adjust feed rate
(
Page 31); adjust blade speed (Page 31).
5. Adjust blade tracking ( Page 68), tension (Page 36).
6. Adjust blade guide roller bearings ( Page 66).
7. Cut and reweld blade, or replace blade (
Page 34).
