Oregon 557849 Professional Filing Guide Instruction Manual

1. Introduction

The Oregon 557849 Professional Filing Guide is designed to provide consistent and accurate sharpening results for chainsaw chains. This guide offers a method for precision sharpening comparable to motorized grinders, at a fraction of the cost.

Key features include:

• Easy installation on the saw bar with the chain in place.
• Precision-built design for accurate filing.
• Consistent sharpening results.
• Replacement parts are available separately.

2. Product Overview

Image 1: The Oregon 557849 Professional Filing Guide. This image shows the filing guide attached to a chainsaw bar, illustrating its compact design and how it positions the file for sharpening.

The filing guide consists of a main body that clamps onto the chainsaw bar, a sliding mechanism for the file, and adjustable components to set the correct filing angles. It is designed for manual operation, guiding the user to maintain precise angles for each tooth.

3. Setup Instructions

1. Prepare the Chainsaw: Ensure the chainsaw is turned off and the chain brake is engaged. Secure the chainsaw in a vise or on a stable surface to prevent movement during sharpening.
2. Attach the Filing Guide: Place the filing guide onto the chainsaw bar, ensuring the chain is in place. Position the guide so that the file aligns with the first tooth to be sharpened.
3. Secure the Guide: Tighten the set screw to firmly clamp the guide to the saw bar. Ensure the guide is stable and does not slip. For improved grip, some users have found it beneficial to modify the set screw tip to a rounded shape or apply adhesive-backed non-skid material to the contact points on the opposite side of the sharpener.
4. Insert the File: Insert the appropriate round file into the guide's holder.
5. Set Angles: Adjust the guide's settings to achieve the correct top plate angle, top plate bevel, and 'down angle' for your specific chain type. Refer to your chainsaw chain manufacturer's specifications for recommended angles. Ensure angle indicators align correctly; if they do not, check the handle's position on the unit.

4. Operating Instructions

1. Identify First Tooth: Begin sharpening with a single tooth, typically on one side of the chain.
2. Position the File: Place the file against the cutting edge of the tooth, ensuring it rests correctly within the guide.
3. File the Tooth: Using smooth, consistent strokes, push the file across the tooth. Only file on the forward stroke. Lift the file slightly on the return stroke to avoid dulling the file. Apply moderate pressure; excessive force is not required and can damage the guide or chain.
4. Maintain Consistency: Count the number of strokes for each tooth to ensure uniform sharpening across all teeth on one side.
5. Sharpen All Teeth on One Side: Once all teeth on one side are sharpened, rotate the chainsaw or reposition the guide to sharpen the teeth on the opposite side. Adjust the guide's angle settings as necessary for the opposing teeth.
6. Check for Burrs: After sharpening, use a flat file to remove any burrs from the top plate and depth gauges.

5. Maintenance

• Cleaning: After each use, clean the filing guide to remove sawdust and debris. Use a brush or compressed air.
• Lubrication: Periodically apply a small amount of light oil (e.g., marine synthetic oil) to the sliding bar and the pad underneath to ensure smooth operation. This can help prevent stiff sliding action.
• Storage: Store the filing guide in a clean, dry place to prevent rust and damage.

6. Troubleshooting

• Issue: Guide slips on the saw bar.
  Solution: Ensure the set screw is tightened sufficiently. Consider modifying the set screw tip to a rounded shape or adding adhesive-backed non-skid material to the contact points for better grip.
• Issue: Angle indicators do not line up or are inconsistent.
  Solution: Verify that the handle is correctly positioned on the unit. Re-check and adjust the angle settings carefully.
• Issue: Stiff sliding action of the file.
  Solution: Apply a small amount of lubricant, such as marine synthetic oil, to the sliding bar and the pad underneath.
• Issue: Plastic fastenings or adjustment mechanisms feel wobbly.
  Solution: Handle the unit with care and avoid applying excessive force during adjustments or filing. While the unit is designed for precision, delicate components require gentle handling.
