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)|
