Secure chainsaw: Clamp bar firmly or use vise; ensure chain brake is engaged.
Disconnect power: Remove spark plug wire on gas saws; unplug electric models.
Handle files carefully: Sharp edges can cause cuts; store properly.
Work in clean area: Clear debris to prevent slips or tool damage.

WARNING! Never sharpen chain while attached to powered saw. Always ensure saw is completely disabled.

Set filing angle: Adjust guide to recommended angle (usually 30° for cross-cutting).
Secure chain: Use clamp or vise to immobilize chainsaw bar.
Position sharpener: Align file with cutter, following angle guide.

Tip: Mark starting cutter with chalk to track progress around chain.

Sharpening Procedure

Step-by-step guide to sharpening chain cutters.

Position file: Insert into guide, align with cutter at set angle.
Apply consistent pressure: Push file forward across cutter in smooth motion.
Maintain angle: Keep file level; follow existing cutter profile.
File each cutter: Use same number of strokes (typically 3-5) per cutter.
Rotate chain: Move to next cutter on same side of bar.
Complete one side: Sharpen all cutters facing same direction.
Rotate saw: Reposition to sharpen cutters on opposite side.
Check uniformity: Visually inspect all cutters for consistent length and angle.

CAUTION! Do not over-file; excessive filing shortens chain life.

Depth Gauge Setting

Proper raker height ensures optimal chip size and reduces kickback.

Locate depth gauges: Found in front of each cutter.
Use depth gauge tool: Place over chain with guide resting on cutter top.
Check height: If raker protrudes above tool, it needs filing.
File rakers: Use flat file to reduce height until flush with tool.
Maintain profile: Keep raker shape consistent; avoid sharp edges.
Repeat for all depth gauges: Ensure uniform height around chain.

Note: File rakers every 3-5 sharpening sessions, or as needed.

Maintenance & Care

Regular maintenance extends sharpener life and performance.

Clean after use: Brush away metal filings; wipe with dry cloth.
Inspect file: Replace when worn or damaged; dull files produce poor results.
Lubricate moving parts: Apply light machine oil to adjustment mechanisms.
Store properly: Keep in case to prevent damage and corrosion.
Check alignment: Verify angle settings remain accurate over time.

CAUTION! Do not use solvents or water; moisture causes rust.

Compatibility Guide

Match sharpener settings to your chain specifications.

Chain Pitch	Recommended File Diameter	Typical Angle
1/4"	5/32"	25°-30°
.325"	5/32"	30°
3/8" (low profile)	5/32"	30°
3/8" (standard)	3/16"	30°-35°
.404"	7/32"	30°-35°

Consult your chainsaw manual for manufacturer-specific recommendations.

Troubleshooting

Problem	Possible Cause	Solution
Chain cuts unevenly	Uneven filing or angles	Re-sharpen with consistent strokes; check angle settings.
Excessive vibration	Uneven cutter lengths	Measure cutters; file longer ones to match shortest.
Chain pulls to one side	More cutters filed on one side	Ensure equal number of cutters sharpened on both sides.
Poor cutting performance	Dull file or incorrect angle	Replace file; verify angle matches chain type.
Depth gauges too high	Not filed regularly	File rakers to proper height using depth gauge tool.
File slips in guide	Worn guide or incorrect size	Replace guide or ensure file diameter matches.

Pro Tip: Always file from inside to outside of cutter for best edge.
