Bullet Tools - Troubleshooting
Before troubleshooting double check the manual:
- Is your shear properly assembled?
- Is it being operated correctly?
- Is it properly lubricated?
- Has the blade been honed as recommended?
Visually inspect shear, watching for objects that might obstruct the blade or powerhead travel:
- Foreign material presence between the blade and anvil, in the pin springs or under the cam.
- Check your blade for chips, cracks or burrs.
- Make sure bearings are intact and lubricated. They should not be spinning/moving on the cam during use.
| Problem | Check First | Check Second | Check Third | Check Fourth |
|---|---|---|---|---|
| Diffificuly cutting | Ensure cam lock is OFF. If equipped, engage power lobes (Model 226) | Make sure handle is FULLY extended | Check blade sharpness / condition | Inspect and lubricate bearings / pins |
| Not cutting completely through material | Inspect pins for oblong/wallowed orifice | Adjust front stroke stop (MAGNUM shears) | Check bearings for wear/play | Ensure blade is proper nominal height |
| Blade sticking after completing cuts | Check/remove & replace blade stops if damaged | Ensure blade screws are tight | Remove anvil, turn it over, reinstall | Check for marks on anvil (overbite) |
| Rough or crushed cuts | Check veneer thickness (max= 1/16") | Check blade condition (chips, burrs, breaks) | Ensure blade is honed and sharp | Review approved materials list |
| Cuts aren't square | Loosen fence screws, align fence, tighten | Check pins for uneven wear | Inspect blade and anvil/bladestop for contact | |
| Handle not returning to open position | Ensure pins are lubricated | Apply grease to contact area of bearing | Lubricate axle bolts | Check springs for breakage |
| Material won't fit into cut area | Check max thickness of material for your shear | Reverse back stroke stop | Ensure blade is proper nominal height | If you have two bearings, switch which bearing is engaged |
| Cam lock pin bent/stuck | Do not lift or carry shear by the handle | Return handle slowly to open position - do not "let it fly" | Disengage cam lock pin BEFORE cutting | |
| Blade chipping | Hone as directed in manual (~25 cuts, then daily) | Do not cut stranded bamboo | Do not cut high pressure laminate | Check veneer thickness (max= 1/16 ") |
| Pin openings wallowed out / oblong where cam axle passes through | Do not lift or carry shear by the handle | Return handle slowly to open position - do not "let it fly" | Check veneer thickness (max= 1/16 ") | Review approved materials list |
| Not cutting to edge of material | Check fence alignment - adjust if needed | Do not "angle" material beyond the blade edge | Ensure angle fence(s) are installed with WIDE edge inward (620 model) |
