Note: Chain should be clean and free of dirt before clamping.
Sharpening Procedure
Follow steps for consistent results.
- Power on: Press switch to start motor.
- Approach wheel: Gently bring cutter into contact with wheel.
- Apply pressure: Use light, even pressure - don't force.
- Sharpen cutter: Hold until sparks become consistent.
- Release pressure: Let wheel clear before moving to next cutter.
- Advance chain: Loosen vise, move to next cutter, retighten.
- Repeat: Sharpen all cutters on one side.
- Reverse chain: Flip chain to sharpen opposite cutters.
- Check consistency: All cutters should have equal length and angle.
WARNING! Never grind for more than 3-4 seconds per cutter to avoid overheating.
Depth Gauge Setting
Proper depth gauge setting prevents kickback and ensures smooth cutting.
- Select tool: Use included depth gauge tool.
- Position tool: Place over chain with gauge on rakers.
- Check height: Rakers should be level with tool.
- File high rakers: Use flat file to reduce height if necessary.
- Check frequently: Set rakers every 3-4 sharpenings.
- Maintain consistency: All rakers should be uniform height.
Important: Incorrect depth gauge setting is a common cause of poor cutting performance.
Maintenance & Cleaning
Regular maintenance ensures optimal performance.
- Wheel dressing: Use dresser to clean wheel surface periodically.
- Bearing lubrication: Apply light oil to moving parts annually.
- Clean vise: Remove chain debris from vise mechanism.
- Inspect wiring: Check power cord for damage.

Troubleshooting
| Symptom | Possible Cause | Corrective Action |
| Motor doesn't start | Power issue/switch | Check power outlet; ensure switch is on; check circuit breaker. |
| Uneven sharpening | Wheel wear/alignment | Dress wheel; check chain positioning; verify angle setting. |
| Excessive sparking | Too much pressure | Reduce pressure; sharpen in shorter bursts. |
| Chain doesn't fit vise | Wrong pitch/vise setting | Verify chain pitch; adjust vise width if adjustable. |
| Poor cutting after sharpening | Wrong angle/depth gauge | Check manufacturer's angle spec; set depth gauges properly. |
| Wheel wobble | Loose mounting/wear | Tighten wheel nut; replace if worn unevenly. |
| Overheating chain | Excessive grinding time | Sharpen for 2-3 seconds only; allow to cool between cutters. |
