Sharpening Procedure

Follow these steps for optimal sharpening results.

Secure chain in vise at correct pitch setting.
Set grinding angle according to chain specifications.
Adjust depth gauge using tool to proper height.
Turn on sharpener and allow wheel to reach full speed.
Gently feed cutter into wheel until spark pattern reaches tip.
Repeat for each cutter, maintaining consistent pressure.
File depth gauges after every 3-5 sharpenings.
Check chain tension and lubrication after sharpening.

Tip: Sharpen all cutters on one side before rotating chain for opposite side.

Grinding Wheel Replacement

Replace wheel when worn or damaged.

Disconnect power from sharpener.
Remove wheel guard by loosening screws.
Use wrench to hold motor shaft while loosening retaining nut.
