Safety Gloves	Optional protection during sharpening

Installation & Setup

Unpack and inspect all components. Ensure work area is clean, stable, and well-lit.

Secure chainsaw: Use clamp to fix bar in vise or stable surface.
Identify chain type: Determine pitch and gauge to select correct file size.
Set filing angle: Adjust guide to match chain manufacturer's specification (usually 30°).
Position depth gauge tool: Align with chain to check raker height.
Wear safety gear: Gloves and eye protection recommended.

WARNING! Ensure chainsaw is completely powered off and cool before sharpening. Disconnect spark plug for gas models.

First-Time Use

Follow these steps for initial sharpening procedure.

Clean chain: Remove dirt, grease, and debris with brush and cleaner.
Inspect chain: Check for damaged, broken, or excessively worn cutters.
Mark starting cutter: Use marker on first tooth to track progress.
File cutting teeth: Apply round file with guide, using smooth forward strokes.
File depth gauges: Use flat file and depth gauge tool to lower rakers.
Repeat for all teeth: Maintain consistent angle and pressure.
Test sharpness: Make test cut in scrap wood to verify performance.

CAUTION! Always file in one direction (away from body). Keep fingers clear of chain teeth.

Specifications

File Sizes: 4mm (5/32"), 4.8mm (3/16"), 5.2mm (13/64") for round files.
Filing Angles: Adjustable from 25° to 35° for standard chains.
Materials: High-carbon steel files, aluminum/plastic guides.
Compatibility: Fits most chainsaw pitches (1/4", .325", 3/8", .404").
Depth Gauge Settings: Typically .025" to .035" below cutter height.
Weight: 0.5 to 2 lbs depending on kit contents.
Storage: Includes case or pouch for organization.
Operating Temp: Standard workshop conditions.

Controls and Components

Primary components: File, guide, depth tool, clamp.

File Guide: Angle adjustment knob, locking mechanism, file channel. Depth Gauge Tool: Height measurement slots, level indicator. Clamp: Bar groove, tightening screw, rubber pads. Angle Guide: Degree markings, alignment arrows.

Adjustments: Filing angle (set via guide markings), file height (position in guide), depth gauge height (using tool), clamp pressure (secure but not damaging).

Connecting to Chainsaw

Secure attachment ensures accurate sharpening.

Turn off and secure chainsaw: Disconnect power source.
Position clamp: Attach to bar near area to be sharpened.
Adjust guide: Set to correct angle for chain type.
Insert file: Place round file into guide channel.
Align depth tool: Hook over chain to check raker height.

Tip: Rotate chain periodically to bring new sections into position. Keep chain tension proper during sharpening.

Sharpening Process

Step-by-step procedure for optimal results.

Position file: Place on cutter at specified angle.
File strokes: Use 3-5 smooth forward strokes per tooth.
Maintain consistency: Same number of strokes for each cutter.
Check progress: Look for shiny metal and uniform shape.
File depth gauges: Lower rakers after every 3-5 sharpenings.
Clean filings: Brush away metal debris regularly.
Inspect chain: Ensure all cutters are same length.
Lubricate chain: Apply chain oil after sharpening.

WARNING! Do not over-file; remove only enough metal to restore edge. Uneven filing causes chain vibration and poor cutting.

Safety Features

Angle guides prevent incorrect filing. Depth tools prevent over-lowering rakers. Clamps secure chain to prevent movement. File guards protect hands. Bright markings for visibility.

Care & Cleaning

Clean after each use. Wipe files with brush to remove filings. Store in dry place. Lightly oil metal parts to prevent rust. Replace worn files (dull or clogged).

CAUTION! Do not use damaged files. Keep tools away from moisture and extreme temperatures.

Regulatory Information

Troubleshooting

Symptom	Possible Cause	Corrective Action
Chain cuts crooked	Uneven filing	Measure cutter lengths; file shorter cutters only.
Excessive vibration	Uneven depth gauges	File all rakers to same height using gauge tool.
Poor cutting performance	Dull file or wrong angle	Replace file; verify angle setting.
File slips in guide	Worn guide or incorrect size	Ensure file matches guide channel; tighten clamp.
Chain binds during cut	Depth gauges too high	Lower rakers to specified height.
Rough finish on wood	Burrs on cutters	Lightly file inside of cutter to remove burr.

Maintenance: Replace files after 8-10 sharpenings. Check guide for wear monthly.
